Cypress CY7C68013A EZ‑USB FX2LP
U2CY7C68013‑56.pdf 

1. With CY7C68013A‑56 chip: low‑power version of the enhanced 51‑core, 16KBprogram data areas, frequency of 48Mhz, 480Mbps high‑speed transmission protocol standards, compatible with USB2.0
2. Firmware, EEPROM: Complete in‑system programming solution with a USB cabledirectly to download firmware, on‑board to provide 16K (24LC128) a large program memory (EEPROM), used as storage VID / PID and the USB firmware, the program space to meet the CY7C68013A Needs.
3. All the GPIO pin through the 2.54mm standard leads to very convenient for learners toexpand DIYdesign.
4. With the board firmware can be achieved through the core function of the logic analyzer
5. PDF format, provide the schematic and code

pull‑up TMS, TDI, pull‑down TCK
Altera recommends that you use pull‑up resistor values between 1k and 10k ohms on the TMS and TDI pins and a pull‑down resistor valueof 1k ohmson the TCK pin.
