AMD XC3164-4PC84I

Overview

XC3164-4PC84I from Xilinx is a high-performance, 4,500-gate Field Programmable Gate Array (FPGA) in the XC3100A family, featuring a 16 × 14 Configurable Logic Block (CLB) array, 120 user I/Os, and guaranteed 370 MHz flip-flop toggle rate with 1.55 ns logic delay. It operates at 5 V, supports TTL/CMOS input thresholds, and integrates on-chip crystal oscillator amplifier for clock generation - used in high-speed digital subsystems such as protocol bridging and real-time signal conditioning.

For engineers reviewing the XC3164-4PC84I datasheet, pinout, applications, or equivalent options, key selection criteria include its 5 V supply compatibility, -4 speed grade (1.55 ns logic delay), industrial temperature range (-40°C to +100°C), and pin-out compatibility with XC3064A and XC3064L devices.

Technical Context

The XC3164-4PC84I implements a static CMOS FPGA architecture with distributed configuration memory cells controlling IOBs, CLBs, and interconnect resources. Its CLBs contain dual 4-input LUTs, two edge-triggered flip-flops per block, programmable clock polarity, and asynchronous reset - enabling synchronous logic synthesis with predictable timing.

Interconnect includes general-purpose metal grids, direct CLB-to-CLB paths (e.g., X→B/C, Y→D/A), and horizontal longlines with TBUF access. Configuration is loaded serially or parallel via external PROM; Soft Startup enforces slew-rate-limited output activation at power-up to suppress ground bounce.

FAQ

What is the maximum operating frequency supported by XC3164-4PC84I?

The XC3164-4PC84I guarantees a 370 MHz flip-flop toggle rate and supports system clock speeds exceeding 85 MHz. Its -4 speed grade specifies a 1.55 ns logic delay, enabling reliable operation in synchronous designs up to 100+ MHz depending on routing and logic depth. Actual achievable frequency depends on design implementation and timing closure verified via Xilinx Foundation or M1 software tools.

Does XC3164-4PC84I support 3.3 V operation?

No, XC3164-4PC84I is a 5 V-only device requiring 5.0 V ± 5% supply. It belongs to the XC3100A family, which does not include low-voltage variants. For 3.3 V operation, consider the pin-compatible XC3164L series - but note that XC3164L has slower performance (4.1 ns delay, 190 MHz toggle) and different voltage tolerance.

Is XC3164-4PC84I pin-compatible with XC3064A-4PC84?

Yes, XC3164-4PC84I is fully pin-out compatible with XC3064A-4PC84 and XC3064L-4PC84 in the 84-pin PLCC package. All share identical I/O count, power/ground pin locations, and function mapping - allowing direct PCB substitution without layout modification.

What configuration memory technology does XC3164-4PC84I use?

XC3164-4PC84I uses static CMOS configuration memory cells - not flash or antifuse. Each cell consists of two cross-coupled inverters and a pass transistor, providing high noise immunity and radiation tolerance. Configuration data is volatile and must be reloaded at power-up from external PROM (e.g., XC17S05), EEPROM, or processor-controlled source.

Does XC3164-4PC84I include built-in oscillator circuitry?

Yes, XC3164-4PC84I integrates an on-chip crystal oscillator amplifier. It supports direct connection of standard parallel-resonant crystals (1–50 MHz) between pins P41 (CK1) and P42 (CK2), eliminating the need for external oscillator components in clock-generation applications.
