A42MX24-FTQG176 概要

The Microchip Technology A42MX24-FTQG176 is a field-programmable gate array (FPGA) from the MX family, offering 36,000 system gates and 912 logic modules in a 176-pin LQFP package. It operates at both 3.3V and 5.0V, providing a flexible, single-chip ASIC alternative for integrating legacy PLDs into a low-cost, high-volume design. The device features 150 user I/Os and is fully compliant with the PCI Local Bus Specification (version 2.1), making it suitable for a wide range of industrial and communication applications.

An FPGA is an integrated circuit that can be programmed after manufacturing to implement custom digital logic functions. Unlike fixed-function ASICs, FPGAs offer reconfigurability, allowing designers to iterate on logic designs without the cost and lead time of custom silicon. The MX family sits within the broader hierarchy of programmable logic devices, bridging the gap between CPLDs and high-density FPGAs, and is optimized for 5V legacy systems while supporting 3.3V operation.

Key features of the A42MX24-FTQG176 include 36K system gates, 912 modules, and 150 user I/Os. The device supports mixed-voltage systems through MultiPlex I/Os, which enable programmable PCI and provide a low-power mode. It also includes D-modules for wide-decode functions, delivering speeds comparable to CPLDs and PALs. The 176-pin LQFP package offers a compact footprint for space-constrained designs.

Technically, the A42MX24 is built on a 0.45um process technology, balancing performance and power consumption. The architecture includes S-modules and C-modules for logic implementation, along with D-modules for wide-input AND functions. The device supports both 3.3V and 5.0V I/O, with internal voltage regulation for core logic. This flexibility allows seamless integration into existing 5V systems while enabling migration to lower-voltage designs.

Typical applications include industrial control, telecommunications, automotive electronics, and legacy system integration. The A42MX24-FTQG176 is ideal for designs that require high I/O count and moderate logic density, such as bus interfaces, memory controllers, and protocol converters. Its PCI compliance makes it suitable for add-on cards and embedded systems.

When designing with this FPGA, consider the power supply requirements: both 3.3V and 5.0V rails may be needed, and proper decoupling is essential. The device supports in-system programming, allowing firmware updates in the field. Ensure adequate thermal management for high-I/O designs, as the LQFP package has limited heat dissipation.

選定ガイド

Choose the A42MX24-FTQG176 when you need a lead-free, RoHS-compliant FPGA with 36K gates and 150 I/Os in a 176-pin LQFP package. It is ideal for new designs requiring environmental compliance. If you do not require RoHS compliance, the A42MX24-TQG176 is a cost-effective alternative. For higher performance, select the A42MX24-1TQG176, but verify timing closure. For cost-sensitive applications with relaxed timing, the A42MX24-3TQG176 may be suitable. For industrial temperature ranges, choose the A42MX24-1TQG176I. For military-grade reliability, the A42MX24-TQG176M is available. All alternatives are pin-compatible, allowing PCB reuse.

  • Standard speed grade with wide availability （vs A42MX24-1TQG176)
  • PCI 2.1 compliance （vs A42MX24-3TQG176)

設計ノート

The A42MX24-FTQG176 supports both 3.3V and 5.0V supplies. Ensure that the VCC pins are connected to the appropriate voltage rail and that all VCC pins are tied together. Use 0.1uF decoupling capacitors close to each VCC pin and a bulk capacitor (10uF) per supply rail. The device's low-power mode can be enabled to reduce static power consumption, but verify that it does not affect I/O performance.

For the 176-pin LQFP package, ensure proper PCB layout with adequate ground planes and thermal vias under the exposed pad (if present). Route high-speed signals with controlled impedance if needed. Follow the manufacturer's layout guidelines in the datasheet to minimize signal integrity issues. Keep traces short for critical signals like clock and reset.

A common pitfall is mixing 3.3V and 5V I/Os without proper configuration. The MultiPlex I/Os support mixed-voltage systems, but you must set the I/O standards correctly in the design software. Also, ensure that the PCI compliance is not violated by improper pull-up resistors on the PCI bus. Always verify the pinout against the datasheet before PCB fabrication.
