AMD XC3195-5PQ208C

Overview

XC3195-5PQ208C from Xilinx is a high-density, static-memory-based Field Programmable Gate Array (FPGA) with 7,500 usable logic gates, 484 Configurable Logic Blocks (22 × 22 array), 176 user I/Os, and guaranteed 370 MHz flip-flop toggle rate. It implements synchronous digital logic via programmable look-up tables and registered I/O, supporting system clock speeds over 85 MHz in industrial temperature range.

For engineers reviewing the XC3195-5PQ208C datasheet, pinout, applications, or equivalent options, key selection criteria include its 208-pin PQFP package, 5 ns logic delay grade, 3.3 V nominal supply compatibility, Soft Startup slew-rate limiting, and bitstream compatibility with XC3000A/XC3100A families.

Technical Context

The XC3195-5PQ208C implements a regular, extendable architecture comprising a perimeter of programmable Input/Output Blocks (IOBs), a core array of Configurable Logic Blocks (CLBs), and distributed static configuration memory cells. Each CLB contains dual 4-input LUTs, two edge-triggered flip-flops, programmable clock polarity, and asynchronous reset.

Its interconnect uses a two-layer metal grid with programmable pass-transistor switching matrices, direct CLB-to-CLB routing paths, and horizontal longlines for high-fanout signal distribution. Configuration is loaded serially or in parallel from external PROMs, with built-in bitstream error checking and automatic soft-start output slew control at power-up.

FAQ

What is the maximum system clock frequency supported by XC3195-5PQ208C?

XC3195-5PQ208C supports system clock frequencies exceeding 85 MHz, with guaranteed flip-flop toggle rates up to 370 MHz. Its -5 speed grade specifies a maximum logic delay of 5 ns, enabling robust timing closure in synchronous designs operating at 85–100 MHz depending on routing and logic depth. Actual achievable clock speed depends on design topology and placement, but the device is characterized to sustain >85 MHz under worst-case industrial conditions.

Does XC3195-5PQ208C support in-system reconfiguration?

Yes, XC3195-5PQ208C supports in-system logic changes via serial or parallel configuration interfaces. Its static RAM-based configuration memory can be reloaded dynamically without power cycle, enabling field updates, partial reconfiguration, and adaptive functionality. The device includes dedicated DIN/DOUT/CCLK pins and INIT status feedback to coordinate safe reconfiguration sequences in live systems.

Is XC3195-5PQ208C pin-compatible with earlier XC3000-series FPGAs?

XC3195-5PQ208C is 100% pin-out compatible with other XC3100A and XC3000A family members in the same PQFP-208 package, including XC3090A-5PQ208C and XC3064A-5PQ208C. However, it is not pin-compatible with XC3000 or XC3100 base families due to expanded I/O count and internal resource mapping. Always verify package footprint and power pin allocation against the specific variant's mechanical drawing.

What configuration memory technology does XC3195-5PQ208C use?

XC3195-5PQ208C uses static RAM (SRAM) configuration memory cells-distributed across the die and controlled by program-configured pass transistors. Each cell consists of two cross-coupled CMOS inverters with a write-enable transistor, providing high noise immunity and radiation tolerance. Unlike volatile DRAM, these cells retain state indefinitely when powered and require no refresh; configuration is loaded at power-up from external PROM or processor memory.

Can XC3195-5PQ208C operate at 5 V?

No, XC3195-5PQ208C is a 3.3 V nominal device with absolute maximum VCC of 3.6 V. It is incompatible with 5 V logic families unless level-shifted. Its I/Os support TTL- or CMOS-threshold inputs and deliver 3.3 V CMOS-compatible outputs with 8 mA drive strength. Direct connection to 5 V buses will damage the device; external translators or resistive dividers are required for mixed-voltage interfacing.
