XC3142A-3PC84C

The Xilinx XC3142A-3PC84C is a high-performance, high-density digital integrated circuit belonging to the XC3000 Series FPGAs. Its user-programmable array architecture is composed of configuration program storage, I/O Blocks (IOBs), Configurable Logic Blocks (CLBs), and interconnection resources.

This specific device offers 3000 logic gates and 144 cells, with a maximum operating frequency of 270MHz and a supply voltage of 5V. It supports system clock rates between 50-85 MHz and features guaranteed flip-flop toggle rates from 190 to 370 MHz, with logic delays ranging from 1.55 to 4.1 ns. The XC3142A-3PC84C also provides 8 mA output sink and source current capabilities, and a maximum quiescent current of 5 mA.

The FPGA's logic functions and interconnections are determined by configuration program data stored in internal static memory cells, which can be loaded externally from sources like EEPROM, EPROM, or ROM. On-chip initialization logic allows for optional automatic program loading at power-up.

Packaged in an 84-pin PLCC, this obsolete part is suitable for applications requiring flexible, user-programmable logic. Design entry is supported by schematic capture and auto place-and-route, with logic and timing simulation available for verification.
