A42MX09-1PQ100

Overview

The A42MX09-1PQ100 is a Field Programmable Gate Array (FPGA) from the Microchip Actel MX family, designed as a single-chip ASIC alternative. It features 336 Configurable Logic Blocks (CLBs), equivalent to 14,000 system gates, and provides up to 104 user-programmable I/O pins. The device supports mixed-voltage operation with core voltages of 3.3V or 5.0V and PCI-compliant I/Os. Key performance metrics include a maximum clock frequency of 70.2 MHz and a CLB-max combination delay of 3.5 ns. It is housed in a 100-pin Plastic Quad Flat Package (PQFP).

Feature Summary

• Single-chip solution integrating logic previously requiring multiple PALs, CPLDs, or FPGAs.
• Supports mixed-voltage operation for both core and I/O supplies at 3.3V or 5.0V.
• Includes deterministic, user-controllable timing and up to 100% pin locking capabilities.
• Offers high-speed wide-decode circuitry and configurable dual-port SRAM resources.

Applications

• High-speed controllers and address decoding systems.
• Peripheral bus interfaces and DSP co-processor functions.
• Replacement for legacy PLD/CPLD designs requiring higher density.

Procurement Notes

Verify the specific suffix '1' against official Microchip documentation to confirm the temperature grade and speed bin, as variations exist within the A42MX09 series. Confirm package integrity for the PQFP-100 form factor. Check for RoHS compliance status and moisture sensitivity level requirements during storage and handling prior to assembly.

Selection Notes

Select this component when a design requires approximately 14,000 system gates with mixed-voltage I/O support. Ensure the 100-pin PQFP footprint fits the PCB layout constraints. Compare against the A42MX09-FPQG100I if industrial temperature ranges (-40°C to +85°C) are required instead of commercial grades.

Part Context

This part belongs to the Microsemi/Actel 40MX and 42MX FPGA families, which were acquired by Microchip Technology. These devices serve as cost-effective alternatives to ASICs, offering high performance and shortened development cycles for embedded logic applications.

Replacement Considerations

The A42MX09-FPQG100I is a verified substitute within the same series, offering identical logical capacity but potentially differing in temperature rating and package variant. Verify pin compatibility before substitution.
