- Page 2 2/18 1 Introduction The XC-1A is a card-sized development board based on the XMOS XS1-G4 event-driven processor device. It comprises a single XS1-G4, 16 user-configurable LEDs, four push- buttons, a speaker, JTAG and serial interfaces, four expansion areas suitable for IDC headers and a through-hole prototyping area for connecting external components.
- Page 3 3/18 2 XS1-G4 Device [A] The XC-1A provides a single XS1-G4 device in a 512BGA package. The XS1-G4 device contains four multithreaded XCore™ processing components with tightly integrated support for communication, I/O and timing. The pins on XCore processors are brought out of the package and connected to the card’s components as follows:...
- Page 4 XC-1A Hardware Manual (1.2) 4/18 To reduce the number of pins required for the 12 clock-LEDs, the LED anodes are connected to four 8-bit ports (8D) on processor 0, 1, 2 and 3 and the cathodes are connected to two 1-bit ports (1E for green, 1F for red) on processor 0.
- Page 5 XC-1A Hardware Manual (1.2) 5/18 The clock-LED pins are mapped to ports on the XS1-G4 as shown in the table below: Port Processor XCore0 X0D40 P8D4 PORT_CLOCKLED_0 [I] X0D41 P8D5 PORT_CLOCKLED_0 [II] X0D42 P8D6 PORT_CLOCKLED_0 [III] X0D12 P1E0 PORT_CLOCKLED_SELG X0D13...
- Page 6 6/18 4 Push-Button Switches [D] The XC-1A provides four push-button switches whose states can be sampled at any time by software. The layout of the push-buttons is shown below. The push buttons are connected to four pins, which are mapped to ports as described in the table below.
- Page 7 XC-1A Hardware Manual (1.2) 7/18 5 I/O Expansion Areas [E] The I/O pins of XCore1, XCore2 and XCore3 are brought out to expansion areas on both sides of the card. These areas have 0.1” pitch plated through holes and are suitable for use with IDC headers.
