1.4 System Memory

The board has two 204-pin SO-DIMM sockets and supports the following memory features:

 1.35 V DDR3L 1600/1866 MHz SDRAM non-ECC SO-DIMM with gold plated contacts on

Intel Celeron processor J3455

 Two memory channels  Unbuffered, single-sided or double-sided SO-DIMMs using 4 Gb or 8 Gb technology

(density)

 8 GB maximum total system memory (with 4 Gb or 8 Gb memory technology). Refer to

Section 2.1.1 on page 37 for information on the total amount of addressable memory.

 Minimum recommended total system memory: 2048 MB  Serial Presence Detect  Optional 2 GB DDR3L 1600 MHz SO-DIMM pre-installed (included in Intel NUC Kit

NUC6CAYS only)

NOTE

To be fully compliant with all applicable DDR SDRAM memory specifications, the board should be populated with SO-DIMMs that support the Serial Presence Detect (SPD) data structure. This allows the BIOS to read the SPD data and program the chipset to accurately configure memory settings for optimum performance. If non-SPD memory is installed, the BIOS will attempt to correctly configure the memory settings, but performance and reliability may be impacted or the SO-DIMMs may not function under the determined frequency.

NOTE

Intel NUC Board NUC6CAYB supports only 4 Gb and 8 Gb memory technologies (also referred to as “SDRAM density”). Table 4 lists the supported SO-DIMM configurations. Table 5 lists the SO-DIMM configurations that are not supported.

1.5.1.1 Video Memory Allocation

Intel® Dynamic Video Memory Technology (DVMT) is a method for dynamically allocating system memory for use as graphics memory to balance 2D/3D graphics and system performance. If your computer is configured to use DVMT, graphics memory is allocated based on system requirements and application demands (up to the configured maximum amount). When memory is no longer needed by an application, the dynamically allocated portion of memory is returned to the operating system for other uses.

1.5.2 High Definition Multimedia Interface* (HDMI*)

The HDMI port supports standard, enhanced, or high definition video, plus multi-channel digital audio on a single cable. The port is compatible with all ATSC and DVB HDTV standards and supports eight full range channels at 24-bit/96 kHz audio of lossless audio formats.

1.6 USB

The USB port arrangement is as follows:

 USB 3.0 ports:

 Two ports are implemented with external front panel connectors (one blue and one

amber charging capable)

 Two ports are implemented with external back panel connectors (blue)  Maximum current is 900 mA for each blue port, 1.5 A for the amber charging port

 USB 2.0 ports:

 Two ports via two single-port internal 1x4 1.25 mm pitch headers (white)  One port is reserved for an M.2 2230 Module  Maximum current is 500 mA for each port of the white headers (1 A total)

All the USB ports are high-speed, full-speed, and low-speed capable.

NOTE

Computer systems that have an unshielded cable attached to a USB port may not meet FCC Class B requirements, even if no device is attached to the cable. Use a shielded cable that meets the requirements for full-speed devices.

1.7 SATA Interface

The SoC provides one SATA port with a theoretical maximum transfer rate of 6.0 Gb/s. A point-to-point interface is used for host to device connections.

The underlying SATA functionality is transparent to the operating system. The SATA controller can operate in both legacy and native modes. In legacy mode, standard IDE I/O and IRQ resources are assigned (IRQ 14 and 15). In Native mode, standard PCI Conventional bus resource steering is used. Native mode is the preferred mode for configurations using Windows* operating systems.

1.7.1 AHCI Mode

The board supports AHCI storage mode.

NOTE

In order to use AHCI mode, AHCI must be enabled in the BIOS. Microsoft* Windows* 10 includes the necessary AHCI drivers without the need to install separate AHCI drivers during the operating system installation process. However, it is always good practice to update the AHCI drivers to the latest available by Intel.

Product Description

1.8 Embedded MultiMediaCard (e-MMC) - optional

The board contains a 32 GB Embedded MultiMediaCard (e·MMC) onboard storage module with Windows 10 Home operating system preinstalled (e-MMC and OS included in Intel NUC Kit NUC6CAYS only).

1.9 Real-Time Clock Subsystem

A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer is not plugged into a wall socket, the battery has an estimated life of three years. When the computer is plugged in, the standby current from the power supply extends the life of the battery. The clock is accurate to  13 minutes/year at 25 ºC with 3.3 VSB applied via the power supply 5 V STBY rail.

NOTE

If the battery and AC power fail, date and time values will be reset and the user will be notified during the POST.

When the voltage drops below a certain level, the BIOS Setup program settings stored in CMOS RAM (for example, the date and time) might not be accurate. Replace the battery with an equivalent one. Figure 1 on page 13 shows the location of the battery.

1.13.1.1 System States and Power States

Under ACPI, the operating system directs all system and device power state transitions. The operating system puts devices in and out of low-power states based on user preferences and knowledge of how devices are being used by applications. Devices that are not being used can be turned off. The operating system uses information from applications and user settings to put the system as a whole into a low-power state.

Table 8 lists the power states supported by the board along with the associated system power targets. See the ACPI specification for a complete description of the various system and power states.

Table 8. Power States and Targeted System Power

Notes:

1. Total system power is dependent on the system configuration, including add-in boards and peripherals powered

by the system chassis’ power supply.

2. Dependent on the standby power consumption of wake-up devices used in the system.

Product Description

1.13.2.1 Power Input

When resuming from an AC power failure, the computer may return to the power state it was

in before power was interrupted (on or off). The computer’s response can be set using the Last Power State feature in the BIOS Setup program’s Boot menu.

1.13.2.2 Instantly Available PC Technology

Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-RAM) sleep-state. While in the S3 sleep-state, the computer will appear to be off (the power supply is off, and the front panel LED is amber if dual colored, or off if single colored.) When signaled by a wake-up device or event, the system quickly returns to its last known wake state. Table 9 on page 32 lists the devices and events that can wake the computer from the S3 state.

The use of Instantly Available PC technology requires operating system support and drivers for any installed PCI Express add-in card.

1.13.2.3 LAN Wake Capabilities

LAN wake capabilities enable remote wake-up of the computer through a network. The LAN subsystem monitors network traffic at the Media Independent Interface. Upon detecting a Magic Packet* frame, the LAN subsystem asserts a wake-up signal that powers up the computer.

1.13.2.4 Wake from USB

USB bus activity wakes the computer from an ACPI S3, S4, and S5 states.

NOTE

Wake from USB requires the use of a USB peripheral that supports Wake from USB.

1.13.2.5 WAKE# Signal Wake-up Support

When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from an ACPI S3, S4, or S5 state.

1.13.2.6 Wake from S5

When the RTC Date and Time is set in the BIOS, the computer will automatically wake from an ACPI S5 state.

1.13.2.7 Wake from Consumer IR

CIR activity wakes the computer from an ACPI S3, S4, or S5 state.

1.13.2.8 +5 V Standby Power Indicator LED

The standby power indicator LED shows that power is still present even when the computer appears to be off. Figure 9 shows the location of the standby power LED.

CAUTION

If AC power has been switched off and the standby power indicator is still lit, disconnect the power cord before installing or removing any devices connected to the board. Failure to do so could damage the board and any attached devices.

1.14 Intel Platform Security Technologies

Intel platform security technologies provides tools and resources to help the user protect their information by creating a safer computing environment.

NOTE

Software with security capability is required to take advantage of Intel platform security technologies.

1.14.1 Intel® Virtualization Technology

Intel Virtualization Technology (Intel® VT) is a hardware-assisted technology that, when combined with software-based virtualization solutions, provides maximum system utilization by consolidating multiple environments into a single server or client.

NOTE

A processor with Intel VT does not guarantee that virtualization will work on your system. Intel VT requires a computer system with a chipset, BIOS, enabling software and/or operating system, device drivers, and applications designed for this feature.

1.14.2 Intel® Platform Trust Technology

Intel® Platform Trust Technology (Intel® PTT) is a platform functionality for credential storage and key management. Intel® PTT supports Microsoft* BitLocker* Drive Encryption for hard drive encryption and supports all Microsoft requirements for firmware Trusted Platform Module (fTPM) 2.0.

NOTE

Support for fTPM version 2.0 requires a UEFI-enabled operating system, such as Microsoft* Windows* 10.

CAUTION

BIOS recovery using the BIOS security jumper clears Intel® Platform Trust Technology (Intel® PTT) keys. These keys will not be restored after the BIOS recovery.

2 Technical Reference

2.1 Memory Resources

2.1.1 Addressable Memory

The board utilizes up to 8 GB of addressable system memory. Typically the address space that is allocated for PCI Conventional bus add-in cards, PCI Express configuration space, BIOS (SPI Flash device), and chipset overhead resides above the top of DRAM (total system memory). On a system that has 8 GB of system memory installed, it is not possible to use all of the installed memory due to system address space being allocated for other system critical functions. These functions include the following:

 BIOS/SPI Flash device (64 Mbit)  Local APIC (19 MB)  Direct Media Interface (40 MB)  PCI Express configuration space (256 MB)  SoC base address registers PCI Express ports (up to 256 MB)  Memory-mapped I/O (I/O fabric) that is dynamically allocated for PCI Express add-in cards

(256 MB)

The board provides the capability to reclaim the physical memory overlapped by the memory mapped I/O logical address space. The board remaps physical memory from the top of usable DRAM boundary to the 4 GB boundary to an equivalent sized logical address range located just above the 4 GB boundary. All installed system memory can be used when there is no overlap of system addresses.

2.2 Connectors and Headers

CAUTION

Only the following connectors and headers have overcurrent protection: back panel and front panel USB.

2.5.1 Power Supply Considerations

Technical Reference

System power requirements will depend on actual system configurations chosen by the integrator, as well as end user expansion preferences. It is the system integrator’s responsibility to ensure an appropriate power budget for the system configuration is properly assessed based on the system-level components chosen.

2.5.2 Fan Header Current Capability

Table 26 lists the current capability of the fan header.

Table 26. Fan Header Current Capability

2.6 Thermal Considerations

CAUTION

A chassis with a maximum internal ambient temperature of 58 oC at the processor fan inlet is recommended. If the internal ambient temperature exceeds 58 oC, further thermal testing is required to ensure components do not exceed their maximum case temperature.

CAUTION

Failure to ensure appropriate airflow may result in reduced performance of both the processor and/or voltage regulator or, in some instances, damage to the board.

All responsibility for determining the adequacy of any thermal or system design remains solely with the system integrator. Intel makes no warranties or representations that merely following the instructions presented in this document will result in a system with adequate thermal performance.

CAUTION

Ensure that the ambient temperature does not exceed the board’s maximum operating

temperature. Failure to do so could cause components to exceed their maximum case temperature and malfunction. For information about the maximum operating temperature, see the environmental specifications in Section 2.8.

CAUTION

The processor voltage regulator area (shown in Figure 19) can reach a temperature of up to

97.5 oC in an open chassis. Ensure that proper airflow is maintained in the processor voltage regulator circuit. Failure to do so may result in shorter than expected product lifetime.

Section 1.2, page 18

Table 27 provides maximum case temperatures for the components that are sensitive to thermal changes. The operating temperature, current load, or operating frequency could affect case temperatures. Maximum case temperatures are important when considering proper airflow to cool the board.

Table 27. Thermal Considerations for Components

To ensure functionality and reliability, the component is specified for proper operation when Case Temperature is maintained at or below the maximum temperature listed in Table 28. This is a requirement for sustained power dissipation equal to Thermal Design Power (TDP is specified as the maximum sustainable power to be dissipated by the components). When the component is dissipating less than TDP, the case temperature should be below the Maximum Case Temperature. The surface temperature at the geometric center of the component corresponds to Case Temperature.

It is important to note that the temperature measurement in the system BIOS is a value reported by embedded thermal sensors in the components and does not directly correspond to the Maximum Case Temperature. The upper operating limit when monitoring this thermal sensor is Tcontrol.

The calculation is based on the Telcordia SR-332-2 Issue 2, Method I, Case 3, 55⁰C ambient. The MTBF prediction is used to estimate repair rates and spare parts requirements. The MTBF for the board is 61,444 hours.

2.8 Environmental

Table 29 lists the environmental specifications for the board.

Table 29. Environmental Specifications

Note: Before attempting to operate this board, the overall temperature of the board must be above the minimum

operating temperature specified. It is recommended that the board temperature be at least room temperature before attempting to power on the board. The operating and non-operating environment must avoid condensing humidity.

3 Overview of BIOS Features

3.1 Introduction

The board uses an Intel Visual BIOS that is stored in the Serial Peripheral Interface Flash Memory (SPI Flash) and can be updated using a disk-based program. The SPI Flash contains the Visual BIOS Setup program, POST, the PCI auto-configuration utility, LAN EEPROM information, and Plug and Play support. The initial production BIOSs are identified as AYAPLCEL.86A.

The Visual BIOS Setup program can be used to view and change the BIOS settings for the computer, and to update the system BIOS. The BIOS Setup program is accessed by pressing the <F2> key after the Power-On Self-Test (POST) memory test begins and before the operating system boot begins.

NOTE

The maintenance menu is displayed only when the board is in configuration mode. Section 2.3 on page 50 shows how to put the board in configuration mode.

3.2 BIOS Flash Memory Organization

The Serial Peripheral Interface Flash Memory (SPI Flash) includes a 64 Mb (8192 KB) flash memory device.

3.3 System Management BIOS (SMBIOS)

SMBIOS is a Desktop Management Interface (DMI) compliant method for managing computers in a managed network.

The main component of SMBIOS is the Management Information Format (MIF) database, which contains information about the computing system and its components. Using SMBIOS, a system administrator can obtain the system types, capabilities, operational status, and installation dates for system components. The MIF database defines the data and provides the method for accessing this information. The BIOS enables applications such as third-party management software to use SMBIOS. The BIOS stores and reports the following SMBIOS information:

 BIOS data, such as the BIOS revision level  Fixed-system data, such as peripherals, serial numbers, and asset tags  Resource data, such as memory size, cache size, and processor speed  Dynamic data, such as event detection and error logging

Non-Plug and Play operating systems require an additional interface for obtaining the SMBIOS information. The BIOS supports an SMBIOS table interface for such operating systems. Using this support, an SMBIOS service-level application running on a non-Plug and Play operating

system can obtain the SMBIOS information. Additional board information can be found in the BIOS under the Additional Information header under the Main BIOS page.

3.4 Legacy USB Support

Legacy USB support enables USB devices to be used even when the operating system’s USB drivers are not yet available. Legacy USB support is used to access the BIOS Setup program, and to install an operating system that supports USB. However, this requires the addition of USB 3.0 drivers to the operating system image prior to beginning installation. By default, Legacy USB support is set to Enabled.

Legacy USB support operates as follows:

1. When you apply power to the computer, legacy support is disabled.

2. POST begins.

3. Legacy USB support is enabled by the BIOS allowing you to use a USB keyboard to enter and

configure the BIOS Setup program and the maintenance menu.

4. POST completes.

5. The operating system loads. While the operating system is loading, USB keyboards and mice

are recognized and may be used to configure the operating system. (Keyboards and mice are not recognized during this period if Legacy USB support was set to Disabled in the BIOS Setup program.)

6. After the operating system loads the USB drivers, all legacy and non-legacy USB devices are

recognized by the operating system, and Legacy USB support from the BIOS is no longer used. This requires the operating system to have USB 3.0 driver support in order to recognize devices attached to any of the NUC6AYB’s external USB ports.

To install an operating system that supports USB, verify that Legacy USB support in the BIOS Setup program is set to Enabled and follow the operating system’s installation instructions.

3.5 BIOS Updates

The BIOS can be updated using either of the following utilities, which are available on the Intel World Wide Web site:

 Intel

 Intel F7 switch during POST allows a user to select where the BIOS .bio file is located and

 Intel Visual BIOS allows the user to select the BIOS .bio file from the internet, USB device,

All utilities verify that the updated BIOS matches the target system to prevent accidentally installing an incompatible BIOS.

Express BIOS Update utility, which enables automated updating while in the Windows environment. Using this utility, the BIOS can be updated from a file on a hard disk, a USB drive (a flash drive or a USB hard drive), or a CD-ROM, or from the file location on the Web.

Flash Memory Update Utility, which requires booting from DOS. Using this utility, the BIOS can be updated from a file on a hard disk, a USB drive (a flash drive or a USB hard drive), or a CD-ROM.

NOTE

Supported file systems for BIOS recovery:

 NTFS (sparse, compressed, or encrypted files are not supported)  FAT32  FAT16  FAT12  ISO 9660

3.7 Boot Options

In the BIOS Setup program, the user can choose to boot from a hard drive, optical drive, removable drive, or the network. The default setting is for the optical drive to be the first boot device, the hard drive second, removable drive third, and the network fourth.

Boot Device Menu Function Keys

Description

<> or <>

Selects a default boot device

<Enter>

Exits the menu, and boots from the selected device

<Esc>

Exits the menu and boots according to the boot priority defined through BIOS setup

NOTE

Optical drives are not supported by the onboard SATA connectors. Optical drives are supported only via the USB interfaces.

3.7.1 Network Boot

The network can be selected as a boot device. This selection allows booting from the onboard LAN or a network add-in card with a remote boot ROM installed.

Pressing the <F12> key during POST automatically forces booting from the LAN. To use this key during POST, the User Access Level in the BIOS Setup program's Security menu must be set to Full.

3.7.2 Booting Without Attached Devices

For use in embedded applications, the BIOS has been designed so that after passing the POST, the operating system loader is invoked even if the following devices are not present:

 Video adapter  Keyboard  Mouse

3.7.3 Changing the Default Boot Device During POST

Pressing the <F10> key during POST causes a boot device menu to be displayed. This menu displays the list of available boot devices. Table 31 lists the boot device menu options.

Table 31. Boot Device Menu Options

Overview of BIOS Features

3.7.4 Power Button Menu

The Power Button Menu is accessible via the following sequence:

1. System is in S4/S5 (not G3)

2. User pushes the power button and holds it down

3. The power LED will change to its secondary color to signal the user to release the power

button (approximately 3 seconds); alternately, the system will emit three short beeps from the PC speaker or headphones, if installed, then stop. Release immediately.

4. User releases the power button before the 4-second shutdown override.

If this boot path is taken, the BIOS will use default settings, ignoring settings in VPD where possible.

The BIOS will display the following prompt and wait for a keystroke:

[ESC] Normal Boot [F2] Intel Visual BIOS [F3] Disable Fast Boot [F4] BIOS Recovery [F7] Update BIOS [F10] Enter Boot Menu [F12] Network Boot

[F3] Disable Fast Boot is only displayed if at least one Fast Boot optimization is enabled.

If an unrecognized key is hit, then the BIOS will beep and wait for another keystroke. If one of the listed hotkeys is hit, the BIOS will follow the indicated boot path. Password requirements must still be honored.

If Disable Fast Boot is selected, the BIOS will disable all Fast Boot optimizations and reset the system.

3.8 Hard Disk Drive Password Security Feature

The Hard Disk Drive Password Security feature blocks read and write accesses to the hard disk drive until the correct password is given. Hard Disk Drive Passwords are set in BIOS SETUP and are prompted for during BIOS POST. For convenient support of S3 resume, the system BIOS will automatically unlock drives on resume from S3. Valid password characters are A-Z, a-z, and 0-9. Passwords may be up to 19 characters in length.

The User hard disk drive password, when installed, will be required upon each power-cycle until the Master Key or User hard disk drive password is submitted.

The Master Key hard disk drive password, when installed, will not lock the drive. The Master Key hard disk drive password exists as an unlock override in the event that the User hard disk drive password is forgotten. Only the installation of the User hard disk drive password will cause a hard disk to be locked upon a system power-cycle.

Table 32 shows the effects of setting the Hard Disk Drive Passwords.

Table 32. Master Key and User Hard Drive Password Functions

During every POST, if a User hard disk drive password is set, POST execution will pause with the following prompt to force the user to enter the Master Key or User hard disk drive password:

Enter Hard Disk Drive Password:

Upon successful entry of the Master Key or User hard disk drive password, the system will continue with normal POST.

If the hard disk drive password is not correctly entered, the system will go back to the above prompt. The user will have three attempts to correctly enter the hard disk drive password. After the third unsuccessful hard disk drive password attempt, the system will halt with the message:

Hard Disk Drive Password Entry Error

A manual power cycle will be required to resume system operation.

NOTE

The passwords are stored on the hard disk drive so if the drive is relocated to another computer that does not support Hard Disk Drive Password Security feature, the drive will not be accessible.

3.9 BIOS Security Features

The BIOS includes security features that restrict access to the BIOS Setup program and who can boot the computer. A supervisor password and a user password can be set for the BIOS Setup program and for booting the computer, with the following restrictions:

 The supervisor password gives unrestricted access to view and change all the Setup options

in the BIOS Setup program. This is the supervisor mode.

 The user password gives restricted access to view and change Setup options in the BIOS

Setup program. This is the user mode.

 If only the supervisor password is set, pressing the <Enter> key at the password prompt of

the BIOS Setup program allows the user restricted access to Setup.

 If both the supervisor and user passwords are set, users can enter either the supervisor

password or the user password to access Setup. Users have access to Setup respective to which password is entered.

 Setting the user password restricts who can boot the computer. The password prompt will be

displayed before the computer is booted. If only the supervisor password is set, the computer boots without asking for a password. If both passwords are set, the user can enter either password to boot the computer.

 For enhanced security, use different passwords for the supervisor and user passwords.  Valid password characters are A-Z, a-z, and 0-9. Passwords may be up to 20 characters in

length.

 To clear a set password, enter a blank password after entering the existing password.

Table 33 shows the effects of setting the supervisor password and user password. This table is for reference only and is not displayed on the screen.
