AMD XC3195-5PQ160C

Overview

XC3195-5PQ160C from Xilinx is a high-density, static CMOS FPGA with 7,500 usable 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 SRAM-based configuration memory, supports TTL/CMOS input thresholds, and integrates on-chip crystal oscillator amplifier for clock generation in embedded control systems.

For engineers reviewing the XC3195-5PQ160C datasheet, pinout, applications, or equivalent options, key selection criteria include its 5 ns logic delay, 8 mA output drive capability, soft-start slew-rate limiting at power-up, architecture compatibility with XC3000A/XC3100A families, and PQ160 ceramic PGA package for thermal stability in industrial timing and interface consolidation.

Technical Context

The XC3195-5PQ160C implements a regular, extendable FPGA architecture comprising a perimeter of programmable I/O Blocks (IOBs), a core array of Configurable Logic Blocks (CLBs), and hierarchical interconnect resources including general-purpose metal grids, direct CLB-to-CLB paths, and horizontal longlines. Its CLBs contain dual 4-input LUTs, two edge-triggered flip-flops sharing asynchronous reset (RD) and enable clock (EC), and programmable inversion on clock (K) inputs.

Configuration is loaded via serial or parallel mode into distributed static memory cells that retain state without refresh; bitstream is compatible with XC3000A and XC3100A families. The device features error-checking during configuration, soft startup (slew-limited initial output activation), and on-chip crystal oscillator amplifier-enabling self-contained clock synthesis without external oscillators.

Manufacturer

Xilinx, founded in 1984, pioneered commercial FPGA technology and established industry standards for reconfigurable logic architecture, development tools, and bitstream security.

The XC3000 Series-including XC3195-5PQ160C-was designed for high-reliability, medium-complexity digital system integration in aerospace, industrial automation, and test equipment where mask-programmed ASICs were cost-prohibitive and PLDs lacked density.

FAQ

What is the maximum guaranteed toggle rate for XC3195-5PQ160C?

The XC3195-5PQ160C has a guaranteed flip-flop toggle rate of 370 MHz across its full industrial temperature range (−40°C to +85°C). This specification is validated per Xilinx datasheet Version 3.1 and reflects worst-case performance under rated VCC and timing conditions-not a typical or average value. The XC3195-5PQ160C achieves this using an advanced CMOS process and optimized CLB routing, enabling high-speed counters and state machines without external clock multiplication.

Does XC3195-5PQ160C support in-system reprogramming?

Yes, XC3195-5PQ160C supports unlimited in-system reprogramming via its serial or parallel configuration interface. Configuration data is loaded into volatile SRAM cells, allowing full logic function changes without device removal. The XC3195-5PQ160C retains no configuration state after power loss, requiring reload from external PROM or processor-enabling field updates, bug fixes, and feature upgrades in deployed systems.

Is XC3195-5PQ160C pin-compatible with other XC3000-series devices?

XC3195-5PQ160C is 100% pin-out compatible with all XC3000A, XC3000L, XC3100A, and XC3100L family members in the PQ160 package. This includes identical power, ground, I/O, clock, and configuration pin assignments. However, internal routing resources and CLB count differ-so while PCB layout is reusable, bitstream is not interchangeable across array sizes like XC3064A or XC3190A.

What voltage levels does XC3195-5PQ160C accept on its I/O pins?

XC3195-5PQ160C supports programmable TTL or CMOS input thresholds per IOB, selectable via configuration bits. Input buffers recognize logic High as ≥2.0 V (TTL) or ≥3.5 V (CMOS) and logic Low as ≤0.8 V (TTL) or ≤1.5 V (CMOS). All I/Os are 5 V tolerant with clamp diodes, but VCCIO is fixed at 5.0 V-no 3.3 V I/O support is provided in this variant.

How does the soft startup feature work in XC3195-5PQ160C?

Upon completion of configuration, XC3195-5PQ160C automatically enables slew-rate limiting on all outputs for the first activation cycle-preventing simultaneous switching noise (SSN) and ground bounce. This hardware-enforced behavior lasts only until the first output transition completes; thereafter, individual I/O slew rates revert to configuration-programmed settings. The feature requires no user code or external circuitry and is active in all power-up scenarios.
