A42MX16-3PQ208I

Overview

The A42MX16-3PQ208I is a Field Programmable Gate Array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features 54,000 system gates and 912 logic elements within a 208-pin PQFP package. The device supports supply voltages of 3V to 3.6V and 4.75V to 5.25V, with an operating temperature range of -40°C to +85°C. It includes up to 2.5 kbits of configurable dual-port SRAM and offers up to 202 user-programmable I/O pins.

Feature Summary

• Provides high-performance single-chip ASIC alternative capabilities with fast wide-decode circuitry.
• Supports mixed-voltage operation for core and I/Os, including PCI-compliant interfaces.
• Enables deterministic, user-controllable timing with up to 100% resource utilization and pin locking.

Applications

• High-speed controllers
• Address decoding
• Peripheral bus interfaces

Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct channels. Confirm RoHS compliance status and check for Product Change Notifications (PCNs) regarding assembly site updates or software modifications. Ensure storage conditions meet moisture sensitivity level requirements prior to soldering.

Selection Notes

Select this model for designs requiring moderate logic density with mixed-voltage compatibility. Verify that the 208-PQFP package fits the board layout constraints. Compare against other MX family members if different I/O counts or temperature grades are needed for the specific application environment.

Part Context

This component belongs to the Microchip 40MX and 42MX FPGA families, which are designed as cost-effective solutions for consolidating logic previously implemented in multiple PALs, CPLDs, and FPGAs. The series emphasizes high performance and shortened development cycles for embedded applications.

Replacement Considerations

Direct substitutes include other variants within the A42MX16 family, such as A42MX16-PQ208I, provided the package and electrical specifications match. Cross-family replacements require careful evaluation of gate count and I/O availability.
