ATF2500C CPLD Family Datasheet

Atmel Corporation 

6. Software Support

All family members of the ATF2500C can be designed with Atmel-WinCUPL.

Additionally, the ATF2500C may be programmed to perform the ATV2500Hs functional subset

(no T-type flip-flops, pin clocking or D/T2 feedback) using the ATV2500H JEDEC file. In this

case, the ATF2500C becomes a direct replacement or speed upgrade for the ATV2500H. The

ATF2500C are direct replacements for the ATV2500B/BQ and the ATV2500H, including the lack

of extra grounds on P4 and P26.

Third Party Programmer Support

Major Third Party Device Programmers support three types of JEDEC files.

Device

Description

ATF2500C (V2500)

V2500 Cross-programming. JEDEC file compatible with standard V2500

JEDEC file (Total fuses in JEDEC file = 71648). The Programmer will

automatically disable the User row fuses and also disable the pin-keeper

feature. The Fuse checksum will be the same as the old ATV2500H/L file.

This Device type is recommended for customers that are directly migrating

from an ATV2500H/L device to an ATF2500C device.

ATF2500C (V2500B)

V2500B Cross-programming. JEDEC file compatible with standard

V2500B JEDEC file (Total fuses in JEDEC file = 71745). The Programmer

will automatically disable the User row fuses and also disable the pin-keeper

feature. The Fuse checksum will be the same as the old

ATV2500B/BQ/BQL/BL file. This Device type is recommended for customers

that are directly migrating from an ATV2500B/BQ/BQL/BL device to an

ATF2500C device.

ATF2500C

Programming of User Row bits supported and Pin keeper bit is user-

programmable. (Total fuses in JEDEC file = 71816). This is the default device

type and is recommended for users that have Re-compiled their Source

Design files to specifically target the ATF2500C device.

Note: The ATF2500C has 71816 Jedec fuses.
