AMD XC3190-PG175CPH

Overview

XC3190-PG175CPH from Xilinx is a high-performance, 6,000-gate Field Programmable Gate Array (FPGA) in a 175-pin ceramic pin-grid array (PG175) package, featuring 320 Configurable Logic Blocks (CLBs), 144 user I/Os, 928 maximum flip-flops, and guaranteed 1.55–4.1 ns logic delays for use in high-speed digital subsystem integration and TTL/MSI replacement.

For engineers reviewing the XC3190-PG175CPH datasheet, pinout, applications, or equivalent options, this page delivers verified architecture compatibility with XC3000A/XC3100A families, Soft Startup slew-rate limiting, on-chip crystal oscillator amplifier support, and confirmed 3.3 V operation with 8 mA I/O drive capability.

Technical Context

The XC3190-PG175CPH implements a static CMOS FPGA architecture with a 16 × 20 CLB array, distributed configuration memory cells, and three-layer interconnect resources including horizontal longlines, general-purpose metal grids, and direct CLB-to-CLB/IOB routing paths. It supports both registered and direct I/O paths with programmable TTL/CMOS input thresholds.

Configuration is loaded via serial or parallel modes using external PROMs (e.g., XC17XX series); on-chip initialization logic enables automatic power-up loading. The device includes error-checking of configuration bitstreams and Soft Startup - a hardware-controlled slew-rate limit applied to 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 developed the first commercial FPGA architecture and established industry standards for reconfigurable computing.

The XC3000 Series - including XC3190-PG175CPH - was designed for high-reliability, medium-complexity digital logic replacement in industrial, aerospace, and medical systems where flexibility, fast time-to-market, and NRE avoidance were critical.

FAQ

What is the operating voltage range for XC3190-PG175CPH?

The XC3190-PG175CPH is a low-voltage device specified for 3.3 V ±0.3 V operation. Its I/O buffers are compatible with both TTL and CMOS logic thresholds, and it draws maximum quiescent current of 5 mA. This voltage range enables direct interfacing with 3.3 V microcontrollers and peripherals without level-shifting circuitry, making XC3190-PG175CPH suitable for battery-powered and energy-efficient industrial modules.

Is XC3190-PG175CPH pin-compatible with other XC3000-series FPGAs?

Yes, XC3190-PG175CPH is 100% pin-out compatible with other XC3000A, XC3000L, XC3100A, and XC3100L family members in the same PG175 package. This includes identical placement of VCC, GND, I/O, clock, and configuration pins. However, functional equivalence requires matching speed grade and voltage variant - XC3190-PG175CPH must be substituted only for other -PGL or -PG175C-marked 3.3 V devices.

Does XC3190-PG175CPH support in-system reprogramming?

Yes, XC3190-PG175CPH supports in-system reprogramming via its serial configuration interface (CCLK/DIN). The device accepts new bitstreams after power-up without requiring physical removal or socketing. This capability enables field-upgradable logic functions, remote diagnostics, and adaptive control algorithms - a key advantage of XC3190-PG175CPH in deployed industrial controllers where firmware updates must occur without hardware intervention.

What configuration memory technology does XC3190-PG175CPH use?

XC3190-PG175CPH uses static CMOS configuration memory cells - not flash or antifuse - arranged in a distributed array across the die. Each cell consists of two cross-coupled inverters and a pass transistor, providing high noise immunity and radiation tolerance. Unlike volatile SRAM-based FPGAs, these cells retain state indefinitely when powered, but require external PROM (e.g., XC1765) for automatic reload at power-up - a defining characteristic of the XC3190-PG175CPH architecture.

Can XC3190-PG175CPH drive 5 V TTL loads directly?

XC3190-PG175CPH outputs are CMOS-compatible with 3.3 V logic levels and 8 mA drive strength, which meets TTL input voltage thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) but cannot safely source/sink into 5 V-biased loads without risk of latch-up. For reliable 5 V TTL interfacing, external level translators or resistive pull-ups to 5 V with current limiting are required. This limitation is inherent to XC3190-PG175CPH's 3.3 V I/O architecture and must be accounted for in schematic design.
