AMD XC3142-PQ100CPH

Overview

XC3142-PQ100CPH from Xilinx is a high-performance Field Programmable Gate Array (FPGA) with 3,000 maximum logic gates, 144 Configurable Logic Blocks (12 × 12 array), 96 user I/Os, and guaranteed 1.55–4.1 ns logic delays. It operates at system clock speeds up to 85 MHz and supports TTL or CMOS input thresholds for embedded digital control and interface logic integration.

For engineers reviewing the XC3142-PQ100CPH datasheet, pinout, applications, or equivalent options, key selection criteria include its 100-pin PQFP package, 3.3 V nominal supply voltage (L-version), soft-start slew-rate limiting on power-up, configuration bitstream error checking, and compatibility with XC3000A/XC3100A bitstreams and footprints.

Technical Context

The XC3142-PQ100CPH implements a static memory-based FPGA architecture with a perimeter of programmable I/O Blocks (IOBs), a core array of 144 CLBs, and hierarchical interconnect resources including general-purpose metal grids, direct CLB-to-CLB paths, and horizontal longlines. Each CLB contains dual 4-input LUTs, two flip-flops with shared asynchronous reset (RD) and enable clock (EC), and programmable inversion on clock (K) and output signals.

Configuration is loaded via serial or parallel mode into distributed SRAM cells; the device supports automatic power-up initialization using external PROMs (e.g., XC17XX series). It features soft startup-slew-rate limiting on all outputs during initial power-up-and configuration bitstream error detection that pulls INIT low on format violation.

FAQ

What is the operating voltage range for XC3142-PQ100CPH?

The XC3142-PQ100CPH operates from 3.0 V to 3.6 V nominal supply voltage. This low-voltage range reduces dynamic and quiescent power versus 5 V XC3000 devices, making it suitable for battery-powered or thermally constrained applications. The XC3142-PQ100CPH specification explicitly defines this as the functional VCC range, with timing parameters guaranteed across the full span.

Does XC3142-PQ100CPH support in-system reprogramming?

Yes, XC3142-PQ100CPH supports full in-system reprogramming via its standard configuration interface. The device accepts serial or parallel configuration data after power-up, allowing logic updates without physical removal. Its soft startup and bitstream error checking features ensure safe, verified reconfiguration - critical for field-upgradable XC3142-PQ100CPH deployments.

Is XC3142-PQ100CPH pin-compatible with XC3042A-PQ100C?

No, XC3142-PQ100CPH is not pin-compatible with XC3042A-PQ100C despite identical PQ100 packaging and 96 I/O count. The XC3142-PQ100CPH uses different power and ground pin allocations optimized for 3.3 V operation and includes dedicated PROGRAM and INIT pins not present in the 5 V XC3042A, requiring PCB layout change for substitution.

What configuration memory technology does XC3142-PQ100CPH use?

XC3142-PQ100CPH uses internal static RAM (SRAM) cells for configuration storage - 30,784 bits total - organized as a distributed array across the die. These cells retain logic definition only while powered; external nonvolatile memory (e.g., XC1736 PROM) is required for automatic reconfiguration at power-up. The SRAM cell design includes dual inverters and a pass transistor for high noise immunity and radiation tolerance.

Can XC3142-PQ100CPH replace XC3042A in an existing design?

XC3142-PQ100CPH cannot directly replace XC3042A without hardware and software modifications. While logic capacity and CLB count match, XC3142-PQ100CPH requires 3.3 V supply (vs. 5 V), has different power/ground pin mapping, and adds PROGRAM/INIT control signals. However, its bitstream compatibility allows reuse of synthesized HDL and place-and-route data after voltage and pinout adaptation.
