A42MX09-PQ160

Overview

The A42MX09-PQ160 is a Field Programmable Gate Array (FPGA) from the Microchip MX series, designed as a high-capacity single-chip ASIC alternative. It features 336 Configurable Logic Blocks (CLBs) and approximately 14,000 system gates. The device supports up to 101 user-programmable I/O pins and includes up to 2.5 kbits of configurable dual-port SRAM. It operates with mixed-voltage capabilities for both core and I/Os at 5.0V or 3.3V. The component is housed in a 160-pin Plastic Quad Flat Package (PQFP) and supports deterministic timing with full resource utilization and pin locking.

Feature Summary

• High-capacity single-chip solution consolidating logic previously implemented in multiple PALs, CPLDs, and FPGAs.
• Supports mixed-voltage operation allowing flexible integration of 5.0V and 3.3V core and I/O standards.
• Provides unique in-system diagnostic and verification capability through Silicon Explorer II technology.
• Enables 100% resource utilization and 100% pin locking for deterministic, user-controllable timing.

Applications

• High-speed controllers and address decoding systems.
• Peripheral bus interfaces requiring mixed-voltage compatibility.
• DSP and co-processor functions within embedded systems.

Procurement Notes

Verify the specific suffix requirements for temperature range and speed grade when sourcing replacements, as standard commercial variants differ from industrial or military specifications. Confirm package integrity upon receipt due to moisture sensitivity level 3 classification. Ensure ESD precautions are strictly followed during handling and storage to prevent damage to the CMOS structure.

Selection Notes

Select this model for designs requiring moderate logic density with significant I/O flexibility. The PQFP-160 package offers a cost-effective surface-mount option compared to ceramic packages. Consider the 2.5 kbits of embedded SRAM for small data buffers. Verify that the target application does not require higher gate counts found in the A42MX16 or A42MX24 variants if future scalability is anticipated.

Part Context

This component belongs to the Microsemi/Microchip 40MX and 42MX FPGA families, which bridge the gap between complex PLDs and large FPGAs. These devices are characterized by fast wide-decode circuitry and low power consumption relative to their performance. The family allows designers to replace multiple discrete logic components with a single programmable chip, reducing board space and assembly complexity.

Replacement Considerations

Direct functional substitutes within the same package include the A42MX09-1PQG160 and A42MX09-2PQG160, differing primarily in speed grades. For higher capacity needs in the same footprint, consider the A42MX16-PQG160A or A42MX16-2PQG160. Note that older 'A' suffix versions may have different voltage tolerances than newer revisions.
