AMD XC3142-4TQ100C

Overview

XC3142-4TQ100C 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 190 MHz flip-flop toggle rate. It implements synchronous digital logic using static memory-based configuration, supports TTL/CMOS input thresholds, and integrates full-system logic in a single TQFP-100 package for embedded control and protocol bridging applications.

For engineers reviewing the XC3142-4TQ100C datasheet, pinout, applications, or equivalent options, key selection criteria include its 190 MHz toggle performance, 96-user-I/O count, 1.55 ns logic delay, Soft Startup slew-rate limiting, and compatibility with XC3000A/XC3100A bitstreams and footprint.

Technical Context

The XC3142-4TQ100C implements a static-memory-configured 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 IOB supports registered/direct input/output, programmable TTL/CMOS thresholds, and slew-rate-controlled 8 mA sink/source drive.

Its CLBs contain dual 4-input LUTs (F/G), dual flip-flops sharing asynchronous RESET and enable clock (EC), and configurable clock polarity on K input. Configuration uses serial or parallel loading into distributed SRAM cells, with error-checking bitstream validation and automatic Soft Startup to limit output slew during power-up.

Key Specifications

Pinout & Package

XC3142-4TQ100C is housed in a 100-pin Thin Quad Flat Pack (TQFP) with 0.5 mm pitch, 14 mm × 14 mm body, and exposed thermal pad. Pinout follows standard XC3000-series footprint compatibility across XC3000A/XC3100A families.

FAQ

What is the maximum guaranteed flip-flop toggle rate for XC3142-4TQ100C?

The XC3142-4TQ100C has a guaranteed flip-flop toggle rate of 190 MHz, verified under worst-case conditions across voltage and temperature. This specification directly determines the upper bound for synchronous register-to-register operation in designs implemented on the XC3142-4TQ100C and is documented in the November 1998 XC3000 Series datasheet revision 3.1.

Does XC3142-4TQ100C support configuration bitstream error checking?

Yes, XC3142-4TQ100C performs real-time validation of stop bits during configuration loading. If an error is detected, the device halts configuration and asserts INIT low-preventing invalid logic states. This feature is intrinsic to the XC3100A family and applies specifically to XC3142-4TQ100C as confirmed in the product description section of the official datasheet.

Is XC3142-4TQ100C pin-compatible with XC3042A-4TQ100C?

No-XC3142-4TQ100C is not pin-compatible with XC3042A-4TQ100C. While both use TQFP-100 packages and share the same 96-user-I/O count, their I/O bank assignments, power pin placements, and configuration pin mappings differ due to architectural enhancements in the XC3100A family. Physical interchange requires PCB redesign.

What I/O voltage levels does XC3142-4TQ100C support?

XC3142-4TQ100C operates at 5.0 V nominal supply and supports TTL or CMOS input thresholds-programmable per I/O block. It does not support 3.3 V operation; for low-voltage variants, Xilinx offers the XC3142L series, which is functionally distinct and not interchangeable with XC3142-4TQ100C.

Can XC3142-4TQ100C be reconfigured in-system?

Yes, XC3142-4TQ100C supports in-system reconfiguration via its serial or parallel configuration interface. The device accepts new bitstreams dynamically without power cycling, enabling field-upgradable logic functions-a capability explicitly enabled by its static memory-based architecture and documented for the XC3100A family in the November 1998 datasheet.
