AMD XC3195-PQ208CPH

Overview

XC3195-PQ208CPH from Xilinx is a high-density, high-performance Field Programmable Gate Array (FPGA) with 7,500 usable logic gates, 484 Configurable Logic Blocks (22 × 22 array), and 176 user I/Os in a 208-pin plastic quad flat package (PQFP). It supports system clock speeds over 85 MHz, offers 1.5 ns minimum logic delay, and integrates on-chip crystal oscillator amplifier for clock generation in embedded digital control and protocol bridging applications.

For engineers reviewing the XC3195-PQ208CPH datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed 370 MHz flip-flop toggle rate, TTL/CMOS input threshold programmability, soft-start slew-rate limiting at power-up, 8 mA output drive capability, and full bitstream compatibility with XC3000A/XC3000L families.

Technical Context

The XC3195-PQ208CPH implements a static CMOS-based FPGA architecture with distributed configuration memory cells controlling IOBs, CLBs, and interconnect resources. Its 22 × 22 CLB array provides 1,320 maximum flip-flops and 44 horizontal longlines for high-fan-out signal distribution and low-skew clock routing.

Each IOB supports registered/direct input paths, programmable 3-state output buffers with slew-rate control, and dual-clock-edge programmability per die edge. The CLB's 32×1 look-up table enables two independent 4-variable functions or one 5-variable function per block, with shared asynchronous reset (RD) and enable clock (EC) across both internal flip-flops.

Key Specifications

Manufacturer

Xilinx, founded in 1984, pioneered commercial FPGA technology and established foundational architectures for reconfigurable logic design.

The XC3000 Series - including XC3195-PQ208CPH - was engineered for high-density digital system integration in cost-sensitive, medium-volume applications where ASIC NRE was prohibitive and PLD logic insufficient.

FAQ

What is the maximum system clock frequency supported by XC3195-PQ208CPH?

The XC3195-PQ208CPH guarantees system clock speeds over 85 MHz, with flip-flop toggle rates up to 370 MHz. This specification is validated across the commercial temperature range (0°C to +70°C) and reflects worst-case timing under full load conditions. Actual achievable clock frequency depends on design topology, routing congestion, and I/O standards used - XC3195-PQ208CPH's 1.5 ns logic delay enables tight timing closure for critical paths in high-speed control applications.

Does XC3195-PQ208CPH support in-system reprogramming?

Yes, XC3195-PQ208CPH supports unlimited in-system reprogramming via its serial or parallel configuration interface. The device loads configuration data from external PROM (e.g., XC17XX series) or microcontroller-controlled memory, enabling field updates without physical replacement. Soft Startup and error-checked bitstream loading ensure safe transitions between configurations - a key capability leveraged in the XC3195-PQ208CPH for dynamic function switching in adaptive systems.

Is XC3195-PQ208CPH pin-compatible with other XC3000-series FPGAs?

XC3195-PQ208CPH is 100% pin-out compatible with other XC3100A family members and maintains footprint compatibility with XC3000A/L devices in the same PQ208 package. However, due to its larger 22×22 CLB array and increased I/O count (176 vs. 144 in XC3190A), direct substitution into smaller-footprint designs requires PCB revision. The XC3195-PQ208CPH pin mapping follows Xilinx's standardized PQFP assignment for the XC3100A series.

What power supply requirements does XC3195-PQ208CPH have?

XC3195-PQ208CPH operates from a single 5.0 V ±5% supply applied to VCC pins, with separate ground connections required for noise isolation. Quiescent current is ≤5 mA in power-down mode, and active power consumption scales with toggle rate and I/O loading. Decoupling capacitors (0.1 µF ceramic + 10 µF tantalum) must be placed within 1 cm of each VCC/GND pair - a requirement explicitly defined in the XC3195-PQ208CPH thermal and electrical specifications to maintain signal integrity.

Can XC3195-PQ208CPH replace XC3000-series devices in existing designs?

XC3195-PQ208CPH is upward-compatible with XC3000A and XC3000L bitstreams, meaning verified configurations for smaller XC3000 devices will load and function correctly. However, due to its larger logic capacity (7,500 gates vs. 6,000 in XC3190A), unused resources remain unallocated unless explicitly targeted. Migration to XC3195-PQ208CPH is feasible for designs needing headroom - the XC3195-PQ208CPH retains identical I/O electrical characteristics and timing models for backward compatibility.
