AMD XC3142-5PP132C

Overview

XC3142-5PP132C from Xilinx is a high-performance Field Programmable Gate Array (FPGA) with 3,000 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 3.3 V, supports TTL/CMOS input thresholds, and integrates full subsystem logic in a single plastic PQFP package for embedded control and digital signal routing.

For engineers reviewing the XC3142-5PP132C datasheet, pinout, applications, or equivalent options, key selection criteria include its 3.3 V operation, 96 I/O count, 144 CLB architecture, Soft Startup slew-rate limiting, and compatibility with XC3000A/XC3100A bitstreams and pinouts.

Technical Context

The XC3142-5PP132C implements a static memory-based FPGA architecture with perimeter I/O Blocks (IOBs), a core array of 144 CLBs, and hierarchical interconnect resources including general-purpose grids, direct CLB-to-CLB paths, and horizontal longlines. Each CLB contains dual flip-flops, five logic inputs (A–E), programmable clock inversion, and a 32×1 LUT supporting two 4-variable functions or one 5-variable function.

Configuration is loaded via serial or parallel mode into distributed SRAM cells; on-chip initialization logic enables automatic power-up loading from external PROMs (e.g., XC17XX series). IOBs support registered/direct I/O, programmable slew rate, 3-state control, passive pull-up, and soft startup-holding all outputs slew-rate limited during initial power-up to suppress ground bounce.

Key Specifications

Pinout & Package

XC3142-5PP132C is housed in a 132-pin Plastic Quad Flat Pack (PQFP) with 0.65 mm pitch, 28.0 × 28.0 mm body, and JEDEC MO-118 compliant footprint. Pin numbering follows standard counter-clockwise convention starting from top-left corner (Pin 1).

Supply support for XC3142-5PP132C includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

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

The XC3000 Series-including XC3142-5PP132C-was designed for mid-density custom logic replacement in cost-sensitive, volume-production embedded systems requiring field-upgradable functionality without ASIC NRE costs.

FAQ

What is the operating voltage range for XC3142-5PP132C?

The XC3142-5PP132C operates at a nominal 3.3 V supply with tolerance of ±0.3 V (3.0–3.6 V). This low-voltage operation reduces dynamic power consumption versus 5 V XC3000A devices while maintaining full I/O compatibility with 3.3 V systems. The XC3142-5PP132C does not support 5 V operation; applying 5 V to VCC will damage the device.

Does XC3142-5PP132C support in-system reconfiguration?

Yes, XC3142-5PP132C supports in-system reconfiguration via serial (CCLK/DIN) or parallel modes. Its static RAM-based configuration allows full bitstream reload without power cycling, enabling field-upgradable logic functions. The XC3142-5PP132C retains configuration only while powered; external PROM (e.g., XC1732) is required for nonvolatile storage.

How many configuration memory bits does XC3142-5PP132C require?

The XC3142-5PP132C requires 30,784 configuration bits, as specified in the XC3000 Series documentation. This value determines the minimum size of external serial PROM (e.g., XC1732 = 32 kbit) needed for automatic power-up loading. Bitstream size is fixed for this density and cannot be reduced by design optimization.

Is XC3142-5PP132C pin-compatible with XC3042A-5PQ132C?

Yes, XC3142-5PP132C is 100% pin-out compatible with XC3042A-5PQ132C and other XC3000-series 132-pin PQFP devices. Both share identical mechanical footprint, power/ground pin allocation, and I/O pin mapping. However, XC3142-5PP132C uses 3.3 V I/O while XC3042A-5PQ132C uses 5 V, so voltage translation is required for interoperability.

What development tools support XC3142-5PP132C?

XC3142-5PP132C is supported by Xilinx Foundation Series and M1 software (v1.5–v3.x), including schematic capture, automatic place-and-route, timing simulation, and bitstream generation. It interfaces with Viewlogic, Cadence, and Mentor Graphics design environments. No newer Xilinx toolchains (ISE, Vivado) support this legacy device.
