3.4.2 Power Supply Topology

3.4.2.1 Input Power

The ATSAMA5D27-WLSOM1-EK1 power source can come through a USB connector (J10) connected to a PC. This USB power source is sufficient to supply the board in most applications.

Important: In case of an external device connected through the USB-B port, it is recommended to use the 5V power supply input with an AC/DC wall adapter for the entire system rather than a PC or a USB hub, which are limited to 500 mA typical.

ATSAMA5D27-WLSOM1-EK1

Baseboard Components

Jumper J16 is used to perform VDD_MAIN current measurements on the baseboard.

The following figure is a schematic of the power source.

Figure 3-4. VDD_MAIN Input Powering

3.4.2.2 Power Supply Requirements and Restrictions

Detailed information on the device power supplies is provided in tables “SAMA5D2 Power Supplies” and “Power Supply Connections” in the SAMA5D2 Series datasheet.

3.4.2.3 Power-up and Power-down Considerations

Power-up and power-down considerations are described in section “Power Considerations” of the SAMA5D2 Series datasheet.

Note: The power-up and power-down sequences provided in the SAMA5D2 Series datasheet must be respected for reliable operation of the device. These are respected by the on-board MCP16502.

3.4.2.3.1 LPDDR2 Power-Off Sequence

The LPDDR2 power-off sequence must be controlled by software to preserve the LPDDR2 device.

In this sequence, the CKE signal should be low during the full period the power rails are powering down.

The power failure can be controlled by the embedded Voltage Supervisor (MIC842) and handled at system level (IRQ on PD31). The LPDDR2 power-off sequence is applied using the bit LPDDR2_LPDDR3_PWOFF in the MPDDRC Low-Power register (MPDDRC_LPR).

3.4.6.2 USB Interfaces

The USB (Universal Serial Bus) is a hot-pluggable general-purpose high-speed I/O standard for computer peripherals. The standard defines connector types, cabling, and communication protocols for interconnecting a wide variety of electronic devices. The USB 2.0 Specification defines data transfer rates as high as 480 Mbps (also known as High-Speed USB). A USB host bus connector uses four pins: a power supply pin (5V), a differential pair (D+ and D- pins) and a ground pin.

The ATSAMA5D27-WLSOM1-EK1 features three USB communication ports named USB-A to USB-C:

• USB-A device interface – One USB device standard Micro-AB connector – Offers a VBUS detection function through the R81-R83 resistor ladder – Used as a secondary power source and as a communication link for the ATSAMA5D27-WLSOM1-EK1, and

derives power from the PC over the USB cable. In most cases, this port is limited to 500 mA.

• USB-B (host port B high- and full-speed interface) – One USB host type C connector – Equipped with a 500 mA high-side power switch

• USB-C (High-Speed Inter-Chip/HSIC port) – One USB high-speed host port with an HSIC interface – Connected to 2 U.FL connectors

3.5 External Interfaces

3.5.1 LCD TFT Interface

The ATSAMA5D27-WLSOM1-EK1 provides an FPC connector with 18 bits of data and control signals to the LCD interface.

This connector is used to connect to an LCD display type AC320005-5.

A 50-pin FPC (J21) header is provided on the baseboard to interface the LCD module with the 18-bit parallel RGB mode and is used to connect to an LCD display type AC320005-5.

The connector provides two PIOs as interrupts, one SPI and a TWI port to interface the MaXTouch® touch controller or QTouch® button controller embedded on the LCD module.

In order to operate correctly from the processor with various LCD modules, two voltage lines are available: 3.3V and 5VCC (default). Both are selected by 0R resistors R107 and FB9.

Two Tri-State Buffers are available on TX and RX lines in order to protect the system against any leakage when an FTDI connector is present and when the system is not started yet.

R152 and R154 are optional (not implemented) resistors that can be used for power selection. Power can be delivered either by the ATSAMA5D27-WLSOM1-EK1 board or by the debug interface tool. To avoid malfunction between the debug interface (e.g., FTDI) and the on-board power system, ensure that the voltage level selected corresponds to the application requirements.

3.7.2 mikroBUS Interfaces

The ATSAMA5D27-WLSOM1-EK1 hosts two pairs of 8-pin female headers acting as mikroBUS interfaces. The mikroBUS standard defines the main board sockets and add-on boards, or Click boards, used for interfacing microprocessors with integrated modules having proprietary pin configuration and silkscreen markings. The pinout consists of three groups of communication pins (SPI, UART and TWI), four additional pins (PWM, interrupt, analog input and reset) and two power groups (+3.3V and GND on the left, and 5V and GND on the right 1x8 header).

3.8.3 VTH Threshold

The ATSAMA5D27-WLSOM1 module mounted on the base board integrates a Voltage Supervisor MIC842.

A resistor ladder is mounted on the ATSAMA5D27-WLSOM1-EK1 board and detects a voltage drop when reduced to

4.64V.

It is possible to change this resistor ladder, values or reference if, for test purposes, another voltage reference is monitored (e.g. 12V). If the reference voltage is above 5.5V, then R60 should be removed (unsoldered).

Microchip Devices Code Protection Feature

Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Legal Notice
