A42MX16-FPQ208

Overview

The A42MX16-FPQ208 is a Field Programmable Gate Array (FPGA) from the Microchip MX series, designed as a single-chip ASIC alternative. It features 608 Logic Elements and approximately 16,000 system gates within a 208-pin Fine-Pitch Quad Flat Package (FPQFP). The device supports mixed-voltage operation with core voltages of 3.3V or 5.0V and I/O levels compatible with 3.3V or 5.0V standards. It includes up to 2.5 kbits of configurable dual-port SRAM for embedded memory functions. The component offers high performance with clock-to-out delays as low as 5.6 ns and supports deterministic timing through user-controllable pin locking.

Feature Summary

• Supports mixed-voltage operation allowing flexible integration of 3.3V and 5.0V logic domains.
• Provides deterministic timing via user-controllable pin locking capabilities.
• Integrates configurable dual-port SRAM for embedded data storage applications.

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interfaces and DSP co-processor functions
• Replacement for legacy PALs, CPLDs, and FPGAs in consolidated designs

Procurement Notes

Verify current availability status as this component may be subject to end-of-life notices. Confirm package type accuracy, as FPQFP variants are distinct from standard PQFP or TQFP options. Ensure design compatibility with required voltage levels and I/O configurations before procurement.

Selection Notes

Select this model when a moderate gate count solution is required for mixed-voltage environments. Consider the 208-pin footprint constraints and verify thermal requirements for the specific operating temperature grade. Compare against higher-capacity MX models if additional logic resources are anticipated.

Part Context

This part belongs to the Microchip 40MX and 42MX FPGA families, which are engineered to replace complex discrete logic and older programmable devices. The family emphasizes cost-effective design solutions with high performance and short development cycles, suitable for consolidating multiple logic functions onto a single chip.

Replacement Considerations

Direct substitutes include other members of the A42MX16 series with different packages, such as A42MX16-PQ208A or A42MX16-TQ144I, depending on board layout constraints. Higher capacity alternatives like the A42MX24 or A42MX36 series may be considered if additional logic resources are needed.
