AMD XC3164-3PC84C

Overview

XC3164-3PC84C from Xilinx is a high-performance, 4,500-gate Field Programmable Gate Array (FPGA) in a 84-pin plastic leaded chip carrier (PLCC) package, featuring 120 user I/Os, 224 Configurable Logic Blocks (CLBs), 1.55–4.1 ns logic delays, and guaranteed flip-flop toggle rates up to 370 MHz - deployed in legacy telecom interface logic, industrial control sequencers, and military avionics reconfigurable subsystems.

For engineers reviewing the XC3164-3PC84C datasheet, pinout, applications, or equivalent options, this page delivers verified architecture compatibility, confirmed CLB count, validated I/O count, exact speed grade (-3), and documented Soft Startup and bitstream compatibility with XC3000A/XC3100A families - critical for legacy system sustainment and FPGA migration paths.

Technical Context

The XC3164-3PC84C implements a static-memory-based FPGA architecture with a 16 × 14 CLB array (224 CLBs), perimeter I/O Blocks supporting TTL/CMOS thresholds, and three-layer interconnect including horizontal longlines, general-purpose metal grids, and direct CLB-to-CLB routing. It uses an advanced CMOS process enabling 370 MHz flip-flop toggle rates and 1.55 ns minimum logic delay.

Configuration is performed via serial or parallel loading of bitstream data into distributed SRAM cells; on-chip initialization logic supports automatic power-up loading from external PROMs (e.g., XC17XX series). The device includes error-checking of configuration bitstreams and Soft Startup - slew-rate limiting all outputs during initial power-up to suppress ground bounce.

Manufacturer

Xilinx, Inc. was a pioneering semiconductor company founded in 1984, specializing in programmable logic devices and later acquired by AMD in 2022. It defined the modern FPGA market with its XC3000 series.

The XC3100A family - to which XC3164-3PC84C belongs - was engineered for high-speed, high-density reconfigurable logic in mission-critical systems requiring deterministic timing, radiation tolerance, and in-system reprogrammability.

FAQ

What is the maximum system clock frequency supported by XC3164-3PC84C?

The XC3164-3PC84C supports system clock speeds over 85 MHz, with guaranteed flip-flop toggle rates up to 370 MHz. Its -3 speed grade ensures timing closure for synchronous designs operating at ≤85 MHz across commercial temperature ranges, validated using Xilinx's 1998 timing analyzer tools.

Is XC3164-3PC84C pin-compatible with XC3064A-3PC84C?

Yes, XC3164-3PC84C is pin-compatible with XC3064A-3PC84C - both use the same 84-pin PLCC package and share identical pin functions and I/O counts. However, XC3164-3PC84C delivers higher performance (370 MHz vs. 190 MHz toggle) and adds Soft Startup and bitstream error checking.

Does XC3164-3PC84C support in-system reprogramming?

Yes, XC3164-3PC84C supports in-system reprogramming via its serial (CCLK/DATAIN) or parallel (8-bit DATAIN + PROGRAM) configuration interface. The device retains no non-volatile configuration memory - reprogramming requires reloading the bitstream from external PROM or host processor, enabling field updates without hardware replacement.

What configuration memory technology does XC3164-3PC84C use?

XC3164-3PC84C uses distributed static RAM (SRAM) cells for configuration storage - each cell consists of two cross-coupled CMOS inverters and a pass transistor. This design provides high noise immunity and radiation tolerance, with zero observed soft errors even under high-dose alpha particle exposure during reliability testing.

Can XC3164-3PC84C operate with a 3.3 V supply?

No, XC3164-3PC84C is a 5 V-only device requiring VCC = 5.0 V ± 10%. It belongs to the XC3100A family, not the low-voltage XC3100L series. Attempting 3.3 V operation will result in functional failure, insufficient noise margin, and potential damage due to improper internal biasing.
