... Green Package Options (Pb/Halide-free/RoHS Compliant) Available 1. Description The ATF2500C is the highest-density PLD available in a 44-pin surface mount pack- age. With its fully connected logic array and flexible macrocell structure, high gate utilization is easily obtainable. The ATF2500C is a high-performance CMOS (electri- cally-erasable) programmable logic device (PLD) that utilizes Atmel’ ...

... 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, four product terms are input to each sum term. Furthermore, each macrocell’s three sum terms can be combined to provide product terms per sum term with no per- formance penalty ...

... A Total of 48 Registers – The ATF2500C provides two flip-flops per macrocell – a total of 48. Each register has its own clock and reset terms, as well as its own sum term. ...

... Power-up Reset The registers in the ATF2500Cs are designed to reset during power-up point delayed slightly from V depend on the polarity of the output buffer. This feature is critical for state as nature of reset and the uncertainty of how V the system, the following conditions are required: 1. The V 2. After reset occurs, all input and feedback setup times must be met before driving the clock pin or terms high, and 3 ...

... Preload and Observability of Registered Outputs The ATF2500Cs registers are provided with circuitry to allow loading of each register asynchro- nously with either a high or a low. This feature will simplify testing since any state can be forced into the registers to control test sequencing priate register high settings ...

... 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 ...

... 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 security fuse also inhibits Preload and Q2 observability. 8. Bus-friendly Pin-keeper Input and I/O All ATF2500C family members have programmable internal input and I/O pin-keeper circuits ...

... Functional Logic Diagram ATF2500C Notes: 1. Pin 4 and Pin 26 are “ground” connections and are not required for PLCC, LCC and JLCC versions of ATF2500C, making them compatible with ATV2500H, ATV2500B and ATV2500BQ pinouts. 2. For DIP package, VCC = P10 and GND = P30. For, PLCC, LCC and JLCC packages, VCC = P11 and P12, GND = P33 and P34, and GND = P4, P26 (See Note 1, above). 0777K– ...
