xCORE-200 explorerKIT is an evaluation board for the configurable xCORE-200
multicore microcontroller products from XMOS. It’s easy to use and provides lots
of advanced features on a small, extremely low cost platform.
xCORE lets you software-configure the interfaces that you need for your system;
so with xCORE-200 explorerKIT you can configure the board to match your exact
requirements. The xCORE-200 multicore microcontroller has sixteen 32bit logical
cores that deliver up to 2000MIPs completely deterministically, making xCORE-200
explorerKIT an ideal platform for functions ranging from robotics and motion
control to networking and digital audio.

2 xCORE Multicore Microcontroller Device
xCORE-200 explorerKIT is based on a two-tile xCORE-200 device (XEF216-512-
TQ128). Each tile is user-programmable, providing eight logical cores with a
total of up to 1000 MIPS compute. A total of 53 general-purpose digital I/O have
been brought out to header pins, providing tremendous flexibility for connecting
peripherals to the xCORE-200 explorerKIT board.

4 Gyroscope and accelerometer
The xCORE-200 explorerKIT provides a BMG160 3-axis gyroscope sensor and an
FXOS8700CQ Digital Sensor (3D Accelerometer ( ± 2g/ ± 4g/ ± 8g) + 3D Magnetome-
ter). These are connected via an I2C interface as described in Figure 7.

7 xSYS connector
The xSYS connector is provided to interface to an xTAG debug adapter. The
xTAG debug adapter allows the xTIMEcomposer tools to interrogate the application
running on the xCORE-200 device using the XMOS debugger and the xSCOPE library
which provides non-intrusive program instrumentation.
8 General purpose push-button switches
Two general purpose push-button switches are provided as shown below. When
depressed, the push-buttons create a connection from the IO to GND. Care must be
taken to ensure that this does not cause undesirable behaviour on the xCORE-200
or other components connected through the GPIO headers:

11 QSPI Flash
xCORE-200 explorerKIT provides 1Mbytes of Quad Serial Peripheral Interface (QSPI)
FLASH memory, which is interfaced by the GPIO connections shown in Figure 16:
The xTIMEcomposer tools include the xFLASH utility for programming compiled
programs into the flash memory. xCORE-200 explorerKIT designs may also access
the FLASH memory at run-time by interfacing with the above pins.

14 Operating requirements
A USB 2.0 high-speed compliant cable of less than 3m in length should be used
when operating the xCORE-200 explorerKIT. XMOS cannot guarantee correct opera-
tion of the xCORE-200 explorerKIT should any other cable be used.
