Features • High-performance, High-density, Electrically-erasable Programmable Logic Device • Fully Connected Logic Array with 416 Product Terms • Maximum Pin-to-pin Delay for 5V Operation • 24 Flexible Output Macrocells – 48 Flip-flops – Two per Macrocell – 72 ...
Page 2
The ATF2500C is organized around a single universal array. All pins and feedback terms are always available to every macrocell. Each of the 38 logic pins are array inputs, as are the out- puts of each flip-flop. In the ATF2500C, ...

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 ...

Security Fuse Usage A single fuse is provided to prevent unauthorized copying of ATF2500C fuse patterns. Once pro- grammed, the outputs will read programmed during verify. The security fuse should be programmed last, as its effect is immediate. The ...
