ispMACH 4256ZE Breakout Board

Evaluation Kit User’s Guide

Appendix C. Known Issues

1.

The ispMACH 4000ZE 1532 interface signals TCK, TMS, TDI and TDO are referenced to VCC=1.8V (logic
core). The ispMACH 4256ZE Breakout Board has an issue where the JTAG signals are connected to the FTDI
which has a 3.3V interface. This circuit should not be replicated in a production board. As a work-around
another FTDI device could be selected or a level translator could be used between the FTDI device and the
ispMACH 4000ZE.
