A42MX09-2PQG100I

Overview

The A42MX09-2PQG100I is a Field Programmable Gate Array from the Microchip A42MX series, housed in a PQFP-100 package. It features 336 Logic Elements and approximately 14,000 system gates. The device supports mixed-voltage operation with a core supply of 3.3V or 5V and I/O supplies ranging from 4.5V to 5.5V. It offers up to 83 user-programmable I/O pins and operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Single-chip ASIC alternative providing high performance logic consolidation
• Mixed-voltage operation capability for 3.3V and 5.0V core and I/Os
• Deterministic, user-controllable timing with pin locking support

Applications

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

Procurement Notes

Verify the specific speed grade suffix against official datasheets, as variations exist within the A42MX09 family. Confirm RoHS compliance status for the specific manufacturing lot. Ensure ESD precautions are taken during handling due to humidity sensitivity classification. Cross-reference the package marking code to distinguish from similar PQFP variants.

Selection Notes

Select this component when a single-chip solution replaces multiple PALs, CPLDs, or FPGAs. Consider the A42MX series for designs requiring deterministic timing and mixed-voltage compatibility. Evaluate the 14,000 gate capacity against logic density requirements before choosing higher-capacity models like the A42MX24.

Part Context

This part belongs to the Microsemi (now Microchip) 40MX and 42MX FPGA families. These devices are designed as cost-effective solutions for 5V applications. The family integrates configurable dual-port SRAM and fast wide-decode circuitry to shorten system design cycles.

Replacement Considerations

The A42MX09-FPQG100I is a documented variant within the same family offering similar gate counts but potentially different timing characteristics. Verify electrical specifications and package dimensions before substitution.
