AMD XC3190-5PQ208I

Overview

XC3190-5PQ208I from Xilinx is a high-density, high-speed Field Programmable Gate Array (FPGA) with 6,000 logic gates, 320 Configurable Logic Blocks (CLBs) in a 16 × 20 array, and 144 user I/Os. It supports system clock speeds over 85 MHz, features TTL/CMOS input thresholds, on-chip crystal oscillator amplifier, and internal 3-state bus capability - deployed in legacy telecom line cards and industrial control backplanes.

For engineers reviewing the XC3190-5PQ208I datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed 370 MHz flip-flop toggle rate, 1.55–4.1 ns logic delay range, soft-start slew-rate limiting at power-up, architecture compatibility with XC3000A/XC3100A families, and PQ208 ceramic package thermal performance.

Technical Context

The XC3190-5PQ208I implements a static memory-based FPGA architecture with distributed configuration memory cells, programmable I/O Blocks (IOBs), and Configurable Logic Blocks (CLBs) interconnected via metal-segment routing grids and longlines. Each CLB contains dual flip-flops, five logic inputs (A–E), programmable clock inversion, and a 32×1 look-up table supporting two 4-variable functions or one 5-variable function.

Configuration is loaded serially or in byte-parallel mode using external PROMs (e.g., XC17XX series); initialization logic enables automatic power-up loading. IOBs support registered/direct input paths, programmable 3-state output buffers with 8 mA sink/source drive, TTL or CMOS threshold selection, and passive pull-up - all controlled by configuration bits.

The XC3000 Series - including XC3190-5PQ208I - was engineered for high-reliability, high-density custom logic replacement in telecom, industrial, and military systems where mask-programmed gate arrays posed NRE and schedule risk.

FAQ

What is the maximum guaranteed flip-flop toggle rate for XC3190-5PQ208I?

The XC3190-5PQ208I has a guaranteed flip-flop toggle rate of 190–370 MHz, with the "-5" speed grade specifying mid-to-high performance binning. This value is validated under worst-case conditions (VCC = 4.75 V, TA = +100°C) and directly impacts synchronous design frequency limits. The XC3190-5PQ208I achieves this using an advanced CMOS process and optimized CLB routing, enabling robust timing closure in high-speed control paths.

Does XC3190-5PQ208I support automatic configuration at power-up?

Yes, XC3190-5PQ208I includes on-chip initialization logic that supports automatic serial configuration loading from external XC17XX-series PROMs upon power-up. This feature eliminates need for external microcontroller intervention and ensures deterministic startup behavior. The XC3190-5PQ208I validates configuration stream integrity before releasing INIT, guaranteeing reliable boot in mission-critical systems.

Is XC3190-5PQ208I pin-compatible with other XC3000-series devices?

Yes, XC3190-5PQ208I is 100% pin-out compatible with all XC3000A, XC3000L, XC3100A, and XC3100L family members in the PQ208 package. This includes identical I/O pin mapping, power/ground pin locations, and configuration interface signals (CCLK, DIN, PROGRAM, INIT). The XC3190-5PQ208I maintains full footprint interchangeability - critical for drop-in replacements in legacy designs.

What I/O voltage standards does XC3190-5PQ208I support?

XC3190-5PQ208I supports both TTL and CMOS input thresholds, configurable per IOB via configuration bits. Its outputs deliver 5 V CMOS-compatible levels with 8 mA sink/source drive, matching standard 5 V logic families. It does not support 3.3 V or mixed-voltage I/O - unlike the XC3190L variant. This makes XC3190-5PQ208I ideal for legacy 5 V systems where level translation would add complexity and skew.

How does the Soft Startup feature work in XC3190-5PQ208I?

The Soft Startup feature in XC3190-5PQ208I automatically limits the slew rate of all outputs during the first activation after configuration completion, preventing simultaneous switching noise and ground bounce. This hardware-enforced behavior lasts only for initial output enable; thereafter, individual I/O slew rates are set by configuration bits. The XC3190-5PQ208I implements this without external components - a key reliability differentiator for high-pin-count 5 V systems.
