AMD XC3190-PQ160CPH

Overview

XC3190-PQ160CPH from Xilinx is a high-density, high-performance Field Programmable Gate Array (FPGA) in the XC3100A family, featuring 6,000 logic gates, a 16 × 20 Configurable Logic Block (CLB) array (320 CLBs), and 144 user I/Os. It delivers guaranteed flip-flop toggle rates up to 370 MHz, logic delays as low as 1.55 ns, and supports system clock speeds over 85 MHz. It is used in high-speed digital subsystem integration, replacing TTL/MSI logic and enabling single-package implementation of complex control and interface logic.

For engineers reviewing the XC3190-PQ160CPH datasheet, pinout, applications, or equivalent options, this page provides verified architecture details, confirmed I/O count and CLB configuration, exact speed-grade specifications, package mapping to PQ160 (Plastic Quad Flat Package, 160-pin), and validated alternatives compatible with XC3100A bitstream and footprint.

Technical Context

The XC3190-PQ160CPH implements a static CMOS-based FPGA architecture with distributed configuration memory cells controlling programmable I/O Blocks (IOBs), Configurable Logic Blocks (CLBs), and hierarchical interconnect resources including general-purpose grids, direct interconnects, and horizontal longlines. Its IOBs support TTL/CMOS input thresholds, programmable slew rate, soft-start output activation, and 8 mA sink/source drive capability.

Each CLB contains dual flip-flops, five logic inputs (A–E), programmable clock polarity, asynchronous reset, and a 32×1 look-up table supporting two independent 4-variable functions or one 5-variable function. Configuration is loaded via serial or parallel modes using external PROMs (e.g., XC17XX series), with error-checking of bitstream framing and automatic INIT assertion on configuration failure.

Manufacturer

Xilinx, Inc. pioneered commercial FPGA technology and developed the XC3000 series as the industry's first widely adopted field-programmable logic platform.

The XC3100A family - including XC3190-PQ160CPH - was designed to extend the XC3000 architecture with higher speed, greater density, and enhanced configuration reliability for demanding embedded control and communications systems.

FAQ

What is the operating voltage range for XC3190-PQ160CPH?

The XC3190-PQ160CPH operates at a nominal 5 V supply voltage with tolerance specified per Xilinx datasheet revision 3.1. It is not compatible with 3.3 V operation; low-voltage variants (e.g., XC3190L) use separate part numbering. Input thresholds are programmable for TTL or CMOS levels, but core logic requires stable 5 V ±5%.

Is XC3190-PQ160CPH pin-compatible with other XC3000-series devices?

Yes - XC3190-PQ160CPH shares identical PQ160 package pinout and footprint with XC3090A-PQ160C and XC3190A-PQ160C. All XC3100A and XC3000A devices in PQ160 packaging maintain 100% architecture and pin-out compatibility, enabling mechanical interchangeability within the same socket.

Does XC3190-PQ160CPH support in-system reprogramming?

Yes - XC3190-PQ160CPH supports in-system configuration via serial or parallel modes using external PROMs or host processors. Its configuration memory is static CMOS-based and retains state indefinitely without refresh; reprogramming requires asserting PROGRAM and reloading the bitstream, enabling field updates without device removal.

What development tools were originally qualified for XC3190-PQ160CPH?

Xilinx Foundation Series and XACT software suites - including schematic capture, automatic place-and-route, logic/timing simulation, and bitstream generation - were fully qualified for XC3190-PQ160CPH. These tools interfaced with Viewlogic, Cadence, and Mentor Graphics environments and supported timing calculator and design editor optimization specific to the XC3100A architecture.

How does the Soft Startup feature function in XC3190-PQ160CPH?

Upon completion of configuration, XC3190-PQ160CPH automatically limits output slew rate for the first activation of all I/Os to suppress ground bounce. This is implemented in hardware and requires no user configuration. After startup, individual I/O slew rates revert to values set by configuration bits - ensuring robust power integrity during boot while preserving timing performance in steady-state operation.
