04/25/01 When does
04/18/01 I can perform in-system programming (ISP) without any problem using the 10-pin ribbon cable of the ATDH2200E programming kit, but I got the expecting 1 but found 0 errers in CPS when I use the ATDH2225 ISP direct download cable.

04/12/01 A pin that is connected to the Reset of the configuration EEPROM can be used as a general output after configuration. If the data from the EEPROM is ignored, what impact might there be from constantly resetting the device?
04/12/01 After a failed instruction to the EEPROM, it no longer produces a clock signal during configuration -- even after being fully programmed and verified by a 3rd party programmer.

04/12/01 In your data sheet, Vih is specified as 2.0v min, however, your programming specification says Vcc*0.7, which works out to 3.5V. If the latter is true, does this mean that the 5V parts cannot reliably interface with 3.3V FPGAs?
04/12/01 Instead of using the write polling method of communicating with the EEPROM, can I set up a delay in my programming routine?
04/12/01 Is there a common package for migration to larger density devices so I can simplify my cascaded serials at a later date?

04/12/01 The AT17LV010 programs and verifies ok but it stops sending data partway through FPGA configuration. A device ID error is reported by my programmer corresponding to 001E 0037.
04/12/01 The bst file read back from the device is larger than the bst file originally written.
04/12/01 The first byte of the EEPROM comes out corrupted. Why?

04/12/01 The reset polarity is incorrect when my power-up time spans 20-30ms.
04/12/01 We have some A part EEPROMs, which does not provide the clock signal during configuration. We tested another parts with different date code, but they worked ok. Is there anything wrong with these parts?

04/12/01 When I try to program the AT17C512-10JC EEPROM using a BP 1200 programmer (third party programmer), I got the device ID error. Do you have a solution to solve this problem?
