The Core Board contains a fully pinned out 8-core xCORE-XA Processor, with its GPIOs connected to header connectors to interface with expansion cards, interposer boards and other external hardware. The Module Board also contains on board debugger hardware for interfacing with the xCORE and ARM processors on the xCORE XA device. 1.2 Module Board Layout The diagram below shows an overview of the layout of the xCORE-XA Module Board. Figure 1: Module Board diagram XM006580A 2 Module Board IN THIS CHAPTER · Setup · Power Supply · Debug · xCORE-XA Boot · XMOS Links · Reset · Clocking · I/O · LEDs · ARM Peripherals The Module Board contains the XMOS device plus support and debug circuitry. A single XS1-XA8A-10-FB265 device has its GPIO connected to the headers. Figure 2: xCORE-XA Module Board 2.1 Setup The Module Board is powered by a 5V external power supply. For debugging, an on board XTAG device is available for debugging the xCOREs and a JLINK-OB device is available for debugging the ARM core. XM006580A xCORE XA Module Board Hardware Manual 2.1.1 6/19 Default Jumper Settings · Power up : Jumpers J8 and J12 should be connected to “xCORE DEF ON” to have the xCORE power default to on. · Boot mode: Jumpers J14 and J16 should be connected to “MSEL” for initial xCORE debugging. · D13 Routing: There is another jumper J15 that selects on board LED or GPIO (X0D13) in one of the I/O header. It should be connected in “LED” position. 2.2 Power Supply Power input can be fed either via a USB micro B connector (J3), or to pin 2 any of the I/O headers. The 5V input supply is used to generate the 3.3V and 1.0V supplies required by the xCORE-XA device. The 5V and 3.3V supplies are connected to the I/O headers, and can be supplied to or by the Module Board. The on board 3.3V supply is capable of supplying 1.25A to external circuits connected to the I/O headers, as long as a suitable 5V adapter is used to provide the system power. 2.2.1 xCORE Power Control The xCORE power is controlled by two jumpers(J8,J9). The jumpers selects xCORE power default to on (XCORE DEF ON) or off. It is also controlled by ARM via GPIO’s PD2 and PD10 to powering it down during low energy mode applications. 2.2.2 Power Supply Monitoring The xCORE-XA power supply can be monitored via low power mode and sleep mode etc. Four ADC signals including two shunt signals with 100:1 gain are used for power monitoring. 2.3 Debug Debug of the system is via the micro USB connector J2, on the bottom side of the Module Board. This should be connected to a host computer for debugging and programming. 2.3.1 Debug LEDs The LEDs indicate the status of the device as shown in the below table. XM006580A xCORE XA Module Board Hardware Manual 7/19 Figure 3: Debug LEDs LED Status Description D1 Green The xTAG is powered on D7 Green Target is running Red Target is in debug mode and stopped Green Target stop reason is expected e.g. breakpoint,print message Red Target stop reason is unexpected e.g.exception Green There is JTAG activity with the target happening Off No JTAG Green Flashing xSCOPE is enabled Off No xSCOPE Green Target device is detected after a Run Configuration or Debug Configuration is used (xrun or xgdb command) Red Target device is not detected after a Run Configuration or Debug Configuration is used (xrun or xgdb command) D13 D12 D8 D6 XM006580A xCORE XA Module Board Hardware Manual 2.3.2 8/19 Debug System Disable The debug system could be powered down(OFF) or enabled (ON) by setting the jumper J13. This allows the board in a standalone mode with typical power usage. 2.4 xCORE-XA Boot The boot mode jumpers J14 & J16 can be selected to boot from ARM flash using LINKS or through external Flash or from xTAG(MSEL). This allows to develop xCORE code independent of ARM code and experiment with xCORE. 2.5 XMOS Links This board contains two 5-bit xCONNECT links XLA and XLB which can be used for connecting more xCORES together. The 2-bit xCONNECT link XLC is used for xSCOPE. 2.6 Reset The reset can be applied to the board in two ways. Manual reset can be generated using push button SW1. In debug mode the reset from xTAG resets the whole system. The reset is connected to all I/O headers so any circuitry on them can be reset. 2.7 Clocking There are two clock sources available in the board. One provides a 48MHZ system clock to both ARM and xCORE. The other is a 32.768 KHZ clock connected to ARM to allow low energy mode applications. 2.8 I/O 2.8.1 xCORE Headers The xCORE signals are identified on the silkscreen layer of the Module Board, the table below lists their relationship to the internal ports.

D2 is connected to PB13 and D4 is connected X0D13. Jumper J15 should be connected to “LED” position to access D4. 2.10 ARM Peripherals xCORE-XA ARM includes dedicated low energy peripherals,low energy sensor interfaces and a full speed USB. ARM I/O header includes peripherals like I2C,UART,USART,PWM and ADC. The I/O from the ARM core in the xCORE-XA is bought out to four headers. The I/O is laid out to give two pairs of similar layout (J6 & J4, J7 & J5) one containing GPIO linked to analogue I/O and the other containing GPIOs linked to digital peripherals.

Each set of I/O headers includes power, ground and reset for maximum flexibility. Flexible power supply options allow this board to be powered from a microUSB supply, supplying the add on board, or from the add on board, via the headers. This board plugs into top of the xCORE-XA industrial board. Custom daughter cards, such as the xCORE-XA vision module and click board interposer can be attached this board. XM006580A 4 New Designs Based on Module Board IN THIS CHAPTER · Power Supply · Debug · I/O There are a number of sections of the design of the xCORE-XA Module Board that have been optimized for flexibility to cover as many use cases as possible. Therefore some consideration may be required in what to leave out or change in a custom design. Some of the important points to consider are dealt with in this section. Some general points to consider when implementing your own design are: · Always check the datasheet of the xCORE device. In the case where the reference design and datasheet conflict, the datasheet presides. · XMOS datasheets contain additional hardware design requirements and guidelines that are not covered in this document, which users of XMOS hardware reference designs must ensure are followed. · The presence of a third party device in an XMOS hardware reference design does not make any statement about its general availability. You must make your own arrangements to ensure that all components can be sourced in the required volumes. 4.1 Power Supply For custom designs the minimum power supply requirements for the xCORE-XA device should be met. A 1.0V supply, capable of supplying at least 500mA is required for the xCORE-XA core, and a 3.3V supply, capable of supplying at least 100mA is required for the xCORE-XA I/O and ARM core supply. The required capability of the 3.3V supply will vary depending on the I/O usage and may need to be higher to supply peripheral devices. The 1.0V, 3.3V supplies and reset should all be sequenced in accordance with the requirements stated in the datasheet. 4.2 Debug In a custom design debug and programming interfaces for both the xCORE cores and the ARM core will be required. A standard XSYS connection should be added to debug and program the xCORE cores by way of an XTAG debug adapter. A standard SWD interface should be implemented, for connection to an external debug adapter. XM006580A xCORE XA Module Board Hardware Manual 4.3 18/19 I/O Attention should be paid to the I/O planning for both the xCORE and ARM cores. The peripherals provided by the ARM core can be multiplexed to a variety of different pin groups, care should be taken to ensure there is no overlap. the xCORE I/O should be mapped, with care taken to ensure that port types are used appropriately, and that bi-directional usage for wide ports is avoided.
