Connectors
All connectors are are for 100mil headers, all connector locations are in 100 mil grid.
JTAG/Debug
Connector JB1 (2 x 6 pin Header) is directly compatible to XMOD JTAG Adapter TE0790, this adapter can be inserted from top onto the TE0725, if JB1 is fitted with male pin header. Optionally JB1 can be fitted with pin header from bottom, in that case the JTAG cable connector must be on the base board.
When using XMOD-JTAG in JB1 then additionally USB UART is usable, and the push-button on XMOD works as configuration reset.
When using XMOD-JTAG please check the switch settings on XMOD to be sure the power and I/O reference are supplied correctly. TE0790 can in some case be used to power up TE0725, this is however not recommended. TE0790-01 has not enough power for TE0725 (LED Blink may work, for larger designs the XMOD delivered power may be not sufficient).
Technical Specification
Power
Single 3.3V Power supply required.
| FPGA | Design | Typical Power, 25C ambient |
|---|---|---|
| A35T | not configured | TBD |
| A35T | LED Blinky | 170mW |
| A100T | not configured | TBD |
Typical power consumption
Connectors
Measurements and placement of the connectors and mounting holes. All 100 mil pin headers are in 100 mil grid, the M3 mounting holes are in 50 mil grid aligned to the centers of the 100mil headers. The module is symmetrical, turning it 180 degrees will keep all I/O and Power Pins in both 50 pin headers in compatible places.
