A42MX24-2PQ208I

Overview

The A42MX24-2PQ208I is a Field Programmable Gate Array (FPGA) from the Microchip A42MX series, designed for industrial and commercial applications. It features 912 Logic Elements and supports up to 176 I/O pins within a 208-pin PQFP package. The device operates on a single 5V supply voltage with a range of 4.75V to 5.25V. It offers an extended industrial temperature range from -40°C to +105°C. The architecture includes non-volatile flash memory for configuration retention and supports JTAG programming.

Feature Summary

• Non-volatile Flash-based architecture eliminates the need for external configuration memory devices.
• Supports in-system programmability via JTAG interface for flexible design updates.
• Provides robust ESD protection and latch-up resistance suitable for harsh environments.
• Integrates high-speed I/O buffers compatible with various logic standards.

Applications

• Industrial control systems requiring reliable programmable logic.
• Automotive electronics operating within extended temperature ranges.
• Communication interface adapters and protocol converters.
• Test and measurement equipment logic functions.

Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +105°C) against the official datasheet. Confirm the package type is 208-pin PQFP. Check for current production status as older FPGA models may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints and programming tools before procurement.

Selection Notes

Select this component when a mid-density FPGA with non-volatile configuration is required. Compare logic element counts against alternative models like the A42MX36 if higher capacity is needed. Verify that the 208-pin PQFP package fits the mechanical constraints. Ensure the design utilizes the available I/O banks and power requirements align with the 5V specification.

Part Context

This part belongs to the Actel/Microchip MX family of Flash-based FPGAs. These devices are known for instant-on capability due to embedded non-volatile memory. The A42MX24 variant provides a balance of logic density and I/O count, positioning it between lower-density PLDs and larger FPGAs. It serves as a drop-in replacement for many complex PAL/GAL designs.

Replacement Considerations

Direct pin-to-pin replacements within the same package and logic density should be verified against the manufacturer's cross-reference guide. Models such as A42MX24-PQ208 or A42MX24-2PQ208 may share physical compatibility but differ in temperature grades or speed bins. Always validate electrical characteristics and timing parameters before substitution.
