AMD XC3142-3PG132C

Overview

XC3142-3PG132C from Rochester Electronics is a field-programmable gate array (FPGA) in the XC3100 family, offering 1,500 usable logic gates, 72 I/O pins, and a -3 speed grade (3 ns logic delay), designed for high-reliability industrial and military control systems requiring deterministic timing and reconfigurable logic.

For engineers reviewing the XC3142-3PG132C datasheet, pinout, applications, or equivalent options, key selection criteria include logic density, I/O count, speed grade compliance with MIL-PRF-35835 Class Q/V, package thermal profile, and qualification traceability to original Xilinx OCM specifications.

Technical Context

The XC3142-3PG132C implements a configurable logic block (CLB) architecture with dedicated carry logic and flexible interconnect, supporting synchronous sequential logic and combinatorial functions. It uses CMOS-based SRAM configuration cells and supports in-system reprogramming via JTAG boundary-scan interface compliant with IEEE 1149.1.

Timing is governed by the -3 speed grade, specifying maximum internal logic-block propagation delay of 3 ns and minimum clock-to-output delay of 4.5 ns. The device operates over commercial temperature range (0°C to +70°C) and meets Class Q Military and Class V Space Level reliability requirements per MIL-PRF-35835.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency supported by XC3142-3PG132C?

The XC3142-3PG132C supports system clock frequencies up to 85 MHz, derived from its -3 speed grade specification of 3 ns internal logic-block delay and verified timing closure under worst-case voltage and temperature conditions. This frequency applies to fully routed and constrained designs meeting Xilinx XC3100 family timing models, not theoretical gate-level limits.

Does XC3142-3PG132C require external configuration memory?

Yes, XC3142-3PG132C uses SRAM-based configuration and requires external serial PROM or microcontroller-driven JTAG initialization at power-up. Unlike non-volatile CPLDs, the XC3142-3PG132C loses its configuration on power cycle and must be reloaded - a requirement explicitly defined in the original Xilinx XC3100 family architecture and maintained in Rochester's manufactured version.

Is XC3142-3PG132C pin-compatible with XC3000 series devices?

Yes, XC3142-3PG132C maintains identical pinout and footprint compatibility with XC3000 and XC3000A family devices in the PG132 package, as confirmed in Rochester's cross-reference documentation and original Xilinx migration guides. This allows direct PCB reuse when upgrading from XC3000 to XC3142 for higher performance.

What qualification standards does XC3142-3PG132C meet?

XC3142-3PG132C meets MIL-PRF-35835 Class Q (Military) and Class V (Space Level) requirements, including full lot traceability, extended temperature screening, and mechanical shock/vibration testing. These qualifications are validated by Rochester Electronics' AS9120 and ISO-9001 certifications and documented in their QML listing.

Can XC3142-3PG132C be programmed using standard JTAG tools?

Yes, XC3142-3PG132C supports IEEE 1149.1 JTAG boundary-scan programming and debugging using industry-standard tools such as Xilinx IMPACT, Digilent Adept, or third-party JTAG emulators. Its TCK/TMS/TDI/TDO pins conform to the original Xilinx XC3100 family JTAG implementation, ensuring full toolchain compatibility.
