A42MX09-PQ160A

Overview

The A42MX09-PQ160A is a Field Programmable Gate Array (FPGA) from the Microchip MX series, housed in a 160-pin PQFP package. It features 14,000 system gates and supports up to 101 user-programmable I/O pins. The device operates with dual voltage supplies: 3V to 3.6V for the core and 4.75V to 5.25V for I/Os. It includes up to 2.5 kbits of configurable dual-port SRAM and offers high-performance logic with clock-to-out times as fast as 5.6 ns. The component is designed for mixed-voltage applications and deterministic timing control.

Feature Summary

• Single-chip ASIC alternative integrating logic previously requiring multiple PALs, CPLDs, or FPGAs
• Mixed-voltage operation supporting both 5.0V and 3.3V core and I/O configurations
• Deterministic, user-controllable timing with up to 100% resource utilization and pin locking
• In-system diagnostic and verification capability via Silicon Explorer II

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces
• DSP and co-processor functions

Procurement Notes

Verify end-of-life status carefully, as the A42MX09 family has been subject to discontinuation notices by Microchip Technology. Confirm current availability through authorized distributors and check for last-time-buy deadlines. Ensure compliance with RoHS and REACH regulations specified in the datasheet before procurement planning.

Selection Notes

Select this model when a cost-effective 5V FPGA solution is required with moderate logic capacity. Compare against higher-gate variants like the A42MX16 or A42MX24 if additional resources are needed. Verify that the 160-pin PQFP package fits the PCB layout constraints and that the commercial temperature range meets operational requirements.

Part Context

This part belongs to the 40MX and 42MX FPGA families, which provide high performance at 5V. These devices consolidate complex logic designs into single chips, reducing board space and development cycles. The MX series is known for its ease of integration and support for legacy design tools while offering modern programmability features.

Replacement Considerations

Direct replacements may be limited due to discontinuation. Consider upgrading to newer Microchip FPGA families such as the IGLOO or ProASIC3L series for long-term supply stability. Evaluate pin-compatible alternatives within the same package type if available.
