A42MX16-PQ208A

Overview

The A42MX16-PQ208A is a Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 608 Logic Elements and approximately 24,000 system gates within a PQFP-208 package. The device supports up to 176 user-programmable I/O pins and operates with a supply voltage range of 4.5 V to 5.5 V, typically at 5 V. It offers an industrial temperature grade ranging from -40°C to +125°C. The component includes up to 2.5 kbits of configurable dual-port SRAM for embedded memory functions.

Feature Summary

• Provides high-performance logic consolidation for applications previously requiring multiple PALs, CPLDs, or FPGAs.
• Supports mixed-voltage operation allowing flexible integration of 3.3V and 5.0V core and I/O standards.
• Enables deterministic timing through user-controllable delay paths and 100% pin locking capabilities.

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interface implementations
• DSP and co-processor function acceleration

Procurement Notes

This component is identified as End-of-Life (EOL). Official discontinuance notifications indicate that manufacturing will cease, and availability is restricted to existing stock or last-time buys. Verification of current lifecycle status against the latest Microchip Product Discontinuance Notification is required before design commitment due to potential obsolescence risks.

Selection Notes

Select this part for legacy designs requiring specific 5V FPGA performance in a PQFP-208 footprint. Ensure compatibility with the MX family toolchain. Verify that the 608 LE capacity meets design requirements, as larger gate counts are available in the A42MX36 series if additional resources are needed.

Part Context

The A42MX16-PQ208A belongs to the Actel/Microchip MX family of radiation-tolerant and high-reliability FPGAs. Originally developed by Microsemi, these devices bridge the gap between complex CPLDs and large-scale FPGAs, offering non-volatile configuration without external memory components.

Replacement Considerations

Direct functional replacements may include the A42MX36 series for higher capacity needs, such as the A42MX36-2PQG208. Designers should evaluate pin-to-pin compatibility and verify software tool support for migration to newer MX family members.
