AMD XC3195-5PG223C

Overview

XC3195-5PG223C from Xilinx is a high-density, high-speed Field Programmable Gate Array (FPGA) with 7,500 logic gates, 484 Configurable Logic Blocks (22 × 22 array), 176 user I/Os, and guaranteed 370 MHz flip-flop toggle rate. It implements custom digital logic in embedded control, protocol bridging, and legacy interface replacement applications using static CMOS configuration memory.

For engineers reviewing the XC3195-5PG223C datasheet, pinout, applications, or equivalent options, key selection criteria include its 22 × 22 CLB architecture, 1.5 ns logic delay, 8 mA output drive, soft-start slew-rate limiting, and full bitstream compatibility with XC3000A/XC3100A families.

Technical Context

The XC3195-5PG223C implements a regular, extendable FPGA architecture composed of perimeter I/O Blocks (IOBs), a core array of Configurable Logic Blocks (CLBs), and programmable interconnect resources. Each CLB contains dual 4-input LUTs, two flip-flops, programmable clock enable, asynchronous reset, and invertible clock inputs.

Configuration is stored in distributed static memory cells, loaded serially or in parallel from external PROM/EEPROM. IOBs support TTL/CMOS input thresholds, registered/direct I/O paths, programmable slew rate, 3-state control, and internal pull-up resistors - all controlled by configuration bits.

Key Specifications

Pinout & Package

XC3195-5PG223C uses a 223-pin Plastic Grid Array (PGA) package with 22 × 22 pin layout and 1.27 mm pitch. The package provides full access to all 176 user I/Os plus dedicated VCC, GND, configuration, and clock pins.

Manufacturer

Xilinx, Inc. is a pioneering semiconductor company founded in 1984, specializing in programmable logic devices and FPGA technology.

The XC3000 Series - including XC3195-5PG223C - was designed for high-density, reprogrammable digital logic implementation in industrial, military, and communications systems where ASIC NRE costs and lead times were prohibitive.

FAQ

What is the maximum system clock frequency supported by XC3195-5PG223C?

The XC3195-5PG223C supports system clock frequencies over 85 MHz, with guaranteed flip-flop toggle rates up to 370 MHz. Its 1.55 ns logic delay and low-skew clock distribution enable reliable operation at 85–100 MHz in well-designed synchronous circuits, subject to place-and-route timing closure.

Does XC3195-5PG223C require external configuration memory?

Yes, XC3195-5PG223C requires external configuration memory such as Xilinx XC17XX series serial PROMs or parallel EEPROM/Flash. The device has no internal non-volatile storage; configuration data is loaded at power-up via CCLK/DIN or parallel mode, and must be retained externally.

Is XC3195-5PG223C pin-compatible with other XC3000-series FPGAs?

XC3195-5PG223C is pin-compatible with other XC3100A family members in the same PG223 package, and shares footprint compatibility with XC3000A/L families. However, it is not pin-compatible with smaller XC3000-series devices (e.g., XC3064) due to differing I/O count and array size.

What I/O standards does XC3195-5PG223C support?

XC3195-5PG223C supports programmable TTL or CMOS input thresholds per IOB, with 8 mA output drive capability. It does not support LVDS, SSTL, or other modern differential standards - its I/Os are strictly single-ended 5 V-tolerant CMOS/TTL compatible.

How does the Soft Startup feature work in XC3195-5PG223C?

The Soft Startup feature in XC3195-5PG223C automatically limits the slew rate of all outputs during initial power-up and configuration completion. This prevents simultaneous switching noise and ground bounce across its 176 I/Os, ensuring stable power rail behavior before full user logic activation.
