budget for all the devices on the board and a correct power-up sequence for the MPU. The power-up and powerdown sequences indicated in the SAM9X60 datasheet must be respected for a reliable operation of the device.

3.1.1 Input Power Options

The SAM9X60-EK board can be powered through:

This section describes the implementation and the circuitry that ensures adequate voltage stability and current

The +5V from the wall adapter is protected through an NCP349 positive overvoltage controller switch. The controller is able to disconnect the system from its output pin when incorrect input operating conditions are detected (5.83V max).

The USB-powered operation comes from the USB device port connected to a PC or a 5VDC supply. The USB supply is enough to power the board in most applications. It is important to note that when the USB supply is used, the USB port has limited power. If USB Host port is required for the application, it is recommended that the external DC supply be used.

• an external AC to DC +5V wall adapter connected via a 2.1 mm center-positive plug into the power jack of the board (J1). The recommended output capacity of the power adapter is 2A,

• USB port A (J7).

Function Blocks

The switch between the two powering options is made by four transistors that ensure the separation between the two when both are plugged. The switch prioritizes powering from the wall adapter to maximize power transfer.

The following figure shows the input power supply topology.

Figure 3-2. Input Power Options

Note: USB-powered operation eliminates additional wires and batteries. It is the preferred mode of operation for any

project that requires only a 5V source at up to 500 mA.

3.1.2 Power Management Integrated Circuit

The MIC2800 is a high-performance power management IC providing three output voltages with maximum efficiency. Integrating a 2-MHz DC/DC converter with an LDO post-regulator, the MIC2800 gives two high-efficiency outputs with a second, 300 mA LDO for maximum flexibility. The DC-to-DC converter uses small values of L and C to reduce board space while still retaining efficiency over 90% at load currents up to 600 mA. For more information about the MIC2800, refer to the product web page.

Each LDO has an independent Enable (EN) pin thus allowing a proper power-up sequence for the MPU. The 20 KΩ resistor in series and the 0.1 µF capacitor in parallel with the EN1 input make a low-pass filter and introduce the necessary delay between the 3.3V and 1.15V rails needed for the proper operation of the MPU. The diode (D1 in

Figure 3-3) ensures that the capacitor fast discharges during the power-down sequence.

Detailed information on the SAM9X60 MPU power supplies and power-up/down considerations are described in section “Electrical Characteristics” in the SAM9X60 device datasheet (see 1.2 Recommended Reading).

The MIC2800-G8S comes preset to supply all the voltage rails needed by the system:

• 1.8V DC/DC supplies SAM9X60 DDR2 pads (VDDIOM) and devices.

• 1.15V LDO1 supplies SAM9X60 Core (VDDCORE).

• 3.3V LDO2 supplies SAM9X60 I/O pads.

The figure below shows the power management scheme.

WARNING

3.1.3 Shutdown Circuitry

The processor can assert the SHDN signal to shut down the PMIC and enter Power-down mode. This is done by pulling both enable pins of the PMIC to GND through a Field Effect Transistor (FET) scheme.

Jumper J3 must not be set to enable this functionality. By setting jumper JP2/J3, the user can shut down the MPU without powering down its power rails.

Figure 3-4. Shutdown Circuitry

SAM9X60-EK

Function Blocks

3.1.4 Battery Unit

A 3.3V battery (supercapacitor) is implemented to permanently maintain the VDDBU voltage.

This function allows the user to shut down the MPU and the system, thus entering a low power mode, and still keep the custom configuration that was previously set in the MPU backup area. While in Shut-down mode, the board can be woken up by action on the SW2 button (WAKE UP), which signals the MPU to resume operations.

Jumper JP1/J2 must be in place for proper operation of the MPU, and can be removed if the user wants to bring the MPU back to the initial configuration, by resetting the General Purpose Backup Registers (GPBR).

Make sure the board is powered off before removing the JP1/J2 jumper.

3.1.5 Current Measurement

Two Microchip DC power/energy monitors are embedded on the SAM9X60-EK board:

• one single high-side current sense monitor PAC1710

• one four-channel current sense monitor PAC1934

Both chips communicate with the MPU via a Two-wire Interface (TWI) and both output their ALERT# signal to a port expander.

The PAC1710 is a single high-side bidirectional current sensing monitor with precision voltage measurement capabilities. The power monitor measures the voltage developed across an external sense resistor to represent the high-side current of a battery or voltage regulator. The PAC1710 also measures the SENSE+ pin voltage and calculates average power over the integration period. The PAC1710 can be programmed to assert the ALERT# pin when high and low limits are exceeded for current sense and bus voltage. For more information about the PAC1710, refer to the product web page.

One current sense resistor is populated on board for measuring voltage and current on the main 5V power rail.

The PAC1934 is a four-channel power/energy monitor with current sensor amplifier and bus voltage monitors that feed high resolution ADCs. Digital circuitry performs power calculations and energy accumulation. The PAC1934 enables energy monitoring with integration periods from 1 ms to up to 36 hours. Bus voltage, sense resistor voltage, and accumulated proportional power are stored in registers for retrieval by the system master or embedded controller. For more information about the PAC1934, refer to the product web page.

3.2.3 Clock Circuitry

The embedded MPU generates its necessary clocks based on two oscillators: one slow clock (SLCK) oscillator running at 32.768 kHz and one main clock oscillator running at 24 MHz.

The main clock oscillator is implemented with a MEMS (Micro Electro-Mechanical System) device DSC1001.

For evaluation purposes, we leave users the freedom to mount a crystal instead, using the PCB footprint reservation (Y1). In that case, resistors R149 and R28 should be removed, resistors R27 and R91 should be populated and capacitors C24 and C25 should be populated with the appropriate load capacitance for the selected crystal.

DDR_VREF

Three reset sources for the SAM9X60 MPU are placed on the board:

• Power-on Reset from the power management unit MIC2800

• User push button reset SW3

• External JTAG or J-Link-OB reset from an in-circuit emulator

Figure 3-11. Processor Reset Circuitry

3.2.5 DDR Controller (MPDDRC)

The SAM9X60 embeds a Multi-Port DDR-SDRAM Controller (MPDDRC) to drive DDR2 and LPDDR1 memories.

Note the following regarding the command and control signal connections between the DDR Controller and the DDR Memory:

• Addresses A0, A1 and A12 are not used on the controller side.

• Addresses A2 to A11 are connected to A0 to A9 on the memory side.

• Signal SDA10 must be connected to A10.

• Addresses A13 to A15 are connected to the last three addresses on the memory side.

• A16 to A18 are connected to BA0 to BA2.

It is recommended to double-check the design schematic against the information provided in the datasheet.

SAM9X60-EK

Function Blocks

The MPDDRC I/Os embed an automatic impedance matching control to avoid overshoots and to reach the best performance levels depending on the bus load and external memories. A serial termination connection scheme, where the driver has an output impedance matched to the characteristic impedance of the line, is used to improve signal quality and reduce EMI. This is done using the ZQ calibration procedure to calibrate the SAM9X60 DDR I/O drive strength. The pin name where the ZQ resistor must be connected is DDR_CAL and, as indicated in the SAM9X60 datasheet for DDR2 case, the resistor value is 20 KOhms.

The DDR_VREF pin serves as a voltage reference input for the DDR I/Os when DDR2 or LPDDR external SDRAM memories are used.

3.2.6 PIOs

The following sections depict all the signals connected to the SAM9X60 MPU ports.

See Table 3-3 for details about each port’s functions.

Figure 3-15. Processor PIOs PB and PD

Some of the ports were multiplexed to accommodate more devices on the evaluation kit and to showcase all the functions the SAM9X60 MPU can address off a single PIO wire.

Most of the ports that share multiple functions are split through passive resistors placed on the board as close to the MPU as possible, therefore no other hardware change must be made. In most cases, the user can use only one of their functions at a time, or can develop a composite driver enabling the use of multiple functions at the same time.
