A42MX16-2PQ208

Overview

The A42MX16-2PQ208 is a Field Programmable Gate Array (FPGA) from the Microchip MX series, housed in a 208-pin PQFP package. It provides 608 Logic Elements and approximately 24,000 system gates. The device supports dual-voltage operation with a core supply of 3V to 3.6V and I/O supplies of 4.75V to 5.25V. It features an industrial temperature range of -40°C to +85°C and includes up to 2.5 kbits of configurable dual-port SRAM for embedded memory functions.

Feature Summary

• Supports mixed-voltage operation allowing independent 3.3V or 5.0V selection for core logic and I/O pins.
• Integrates configurable dual-port SRAM to facilitate embedded processing and data buffering tasks.
• Enables deterministic timing through user-controllable pin locking and resource utilization.

Applications

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

Procurement Notes

Verify component authenticity through authorized Microchip distributors due to the availability of counterfeits in the market. Confirm that the specific suffix matches the required voltage and temperature grades. Check for recent Product Change Notifications regarding assembly site updates or software tool compatibility changes before finalizing procurement plans.

Selection Notes

Select this model when a single-chip ASIC alternative is needed to consolidate multiple PALs or CPLDs. Ensure the design requires the specific 208-pin form factor and the 24,000 gate capacity. Verify that the target application operates within the specified 3V to 3.6V core voltage range and utilizes the available I/O standards.

Part Context

This component belongs to the Microsemi/Actel MX family, known for non-volatile Flash-based FPGA technology. The A42MX16 variant specifically targets mid-range complexity applications requiring high performance at 5V. It serves as a bridge between traditional programmable logic devices and more complex FPGAs.

Replacement Considerations

Direct replacements include other variants within the A42MX16 series with different packages, such as A42MX16-VQG100 or A42MX16-PQ100. Cross-family migration to the A42MX40 series may be necessary if higher gate counts are required, though pinouts will differ significantly.
