AMD XC3190-5PQ160I

Overview

XC3190-5PQ160I from Xilinx is a high-performance, 6,000-gate Field Programmable Gate Array (FPGA) in a 160-pin plastic quad flat package (PQFP), featuring 144 user I/Os, 928 maximum flip-flops, and guaranteed 1.55–4.1 ns logic delays. It implements configurable logic blocks (CLBs), programmable I/O blocks (IOBs), and hierarchical interconnect resources for digital system integration in industrial control and communications interfaces.

For engineers reviewing the XC3190-5PQ160I datasheet, pinout, applications, or equivalent options, this device supports TTL/CMOS input thresholds, on-chip crystal oscillator amplifier, soft-start slew-rate limiting at power-up, configuration bitstream error checking, and full software/bitstream compatibility with XC3000A/L and XC3100A/L families.

Technical Context

The XC3190-5PQ160I implements a static memory-based FPGA architecture with a 16 × 20 array of Configurable Logic Blocks (CLBs), each containing dual flip-flops, five-input look-up tables, and programmable clock enable/reset controls. Its IOBs support registered/direct I/O paths, programmable 3-state output control, and selectable slew rate.

Interconnect resources include general-purpose metal grids, direct CLB-to-CLB routing, and horizontal longlines with TBUF access. Configuration is loaded via serial or parallel mode using external PROMs (e.g., XC17XX series), with automatic initialization and bitstream integrity verification during startup.

Manufacturer

Xilinx, founded in 1984, pioneered commercial FPGA technology and developed the XC3000 series as its first widely adopted programmable logic platform for high-density digital system integration.

The XC3100A family-including XC3190-5PQ160I-was designed to deliver enhanced speed and density over the XC3000A series while maintaining full backward compatibility, targeting demanding applications in industrial automation and communications infrastructure.

FAQ

What is the operating voltage requirement for XC3190-5PQ160I?

XC3190-5PQ160I operates at a nominal VCC of 5.0 V ± 5%, with absolute maximum ratings of 5.5 V. It is not compatible with 3.3 V supply rails; for low-voltage operation, the pin-compatible XC3190L-5PQ160I (3.0–3.6 V) must be used instead. All I/O thresholds, internal logic levels, and configuration circuitry are designed specifically for 5 V CMOS operation in XC3190-5PQ160I.

Does XC3190-5PQ160I support in-system reprogramming?

Yes, XC3190-5PQ160I supports unlimited in-system reprogramming via its standard configuration interface. The device accepts serial or parallel configuration data after power-up, allowing logic changes without physical replacement. Soft Startup and bitstream error checking remain active during each reconfiguration cycle, ensuring reliable updates in deployed systems. XC3190-5PQ160I retains full bitstream compatibility with XC3000A/L and XC3100A/L families for seamless migration.

What package type and pin count does XC3190-5PQ160I use?

XC3190-5PQ160I uses a 160-pin plastic quad flat package (PQFP) conforming to JEDEC MS-026, with 0.65 mm lead pitch and 28 mm × 28 mm body dimensions. All 144 user I/O pins are arranged in four peripheral banks, plus dedicated power, ground, configuration, and clock pins. This PQFP package is mechanically and electrically identical across all XC3190 speed grades (-4, -5, -6) and voltage variants (A/L).

How many configuration memory bits does XC3190-5PQ160I require?

XC3190-5PQ160I requires exactly 64,160 configuration bits to define its logic functionality, interconnect routing, and I/O settings. These bits are loaded into distributed static memory cells within the FPGA fabric and determine CLB behavior, IOB configuration, and switch matrix states. The bitstream format is validated during loading, and any error in stop-bit placement causes INIT to assert low, halting configuration-this mechanism ensures deterministic initialization in XC3190-5PQ160I.

Is XC3190-5PQ160I pin-compatible with other XC3000-series FPGAs?

Yes, XC3190-5PQ160I is fully pin-compatible with all XC3000A, XC3000L, XC3100A, and XC3100L devices in the same PQ160 package, including XC3090A/L and XC3195A. Pin functions-including I/O, power, clock, and configuration signals-are identically mapped. This enables drop-in replacement across speed grades and voltage variants, provided the target application meets the electrical and timing requirements of the selected part.
