AMD XC3142-TQ144IPH

Overview

XC3142-TQ144IPH 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 190–370 MHz flip-flop toggle rates. It implements synchronous digital logic using static configuration memory, supports TTL/CMOS input thresholds, and integrates on-chip crystal oscillator amplifier for clock generation in embedded control and data-path acceleration applications.

For engineers reviewing the XC3142-TQ144IPH datasheet, pinout, applications, or equivalent options, key selection criteria include its 144-pin TQFP package, 3.3 V nominal supply (L-version), Soft Startup slew-rate limiting, bitstream compatibility with XC3000A/L families, and support for automatic serial configuration via XC17XX PROMs.

Technical Context

The XC3142-TQ144IPH uses a distributed static RAM-based configuration memory architecture with programmable I/O Blocks (IOBs), Configurable Logic Blocks (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 at power-up via serial (e.g., XC1701–XC1764 PROMs) or parallel modes; the device includes built-in bitstream error checking and automatic INIT low assertion on configuration failure. IOBs support registered/direct inputs, programmable slew rate, 3-state control, passive pull-up, and selectable TTL/CMOS input thresholds - all controlled by configuration bits.

Key Specifications

Pinout & Package

Manufacturer

Xilinx, Inc. pioneered commercial FPGA technology and developed the XC3000 series as the industry's first widely adopted reprogrammable logic platform.

The XC3100A family-including XC3142-TQ144IPH-was designed to deliver higher-speed, pin-compatible upgrades to XC3000A/L systems while enabling seamless migration from TTL/PLD-based designs to single-chip logic integration.

FAQ

What is the maximum system clock frequency supported by XC3142-TQ144IPH?

XC3142-TQ144IPH supports system clock speeds over 85 MHz, with guaranteed flip-flop toggle rates up to 370 MHz. This performance derives from its advanced CMOS process and optimized interconnect architecture, enabling high-speed synchronous logic in applications such as digital test equipment and real-time control. The actual achievable clock frequency depends on design placement, routing, and timing closure - verified using Xilinx Foundation or M1 software tools.

Does XC3142-TQ144IPH require an external configuration PROM?

Yes, XC3142-TQ144IPH requires an external configuration PROM such as the XC1701–XC1764 series for automatic loading at power-up. The device itself contains no non-volatile configuration storage; its static RAM-based configuration memory must be reloaded each time power is applied. Serial configuration via DIN/CCLK is the most common method, though parallel modes are also supported depending on board design.

Is XC3142-TQ144IPH pin-compatible with XC3042A-TQ144C?

Yes, XC3142-TQ144IPH is pin-compatible with XC3042A-TQ144C - both use identical 144-pin TQFP packages and share the same I/O pin mapping. However, XC3142-TQ144IPH operates at 3.3 V and includes additional features like Soft Startup and configuration error checking, whereas XC3042A-TQ144C is a 5 V device without those enhancements.

What I/O standards does XC3142-TQ144IPH support?

XC3142-TQ144IPH supports programmable TTL or CMOS input thresholds per I/O block, with 4 mA (8 mA in XC3100A variants) sink/source drive capability. Outputs are CMOS-compatible and configurable for slew rate, 3-state control, and logic inversion. It does not support LVDS, SSTL, or other differential or high-speed I/O standards - those were introduced in later Xilinx families.

Can XC3142-TQ144IPH be reprogrammed in-system?

Yes, XC3142-TQ144IPH supports in-system reprogramming via its serial or parallel configuration interfaces. The configuration memory is SRAM-based and can be reloaded dynamically without power cycling, enabling field updates and logic changes during operation. This capability is used in applications like adaptive test equipment and reconfigurable communication gateways where functionality must evolve post-deployment.
