A42MX16-PQG208I

Overview

The A42MX16-PQG208I is a high-performance Field Programmable Gate Array (FPGA) from the Microchip MX series, designed as a single-chip ASIC alternative. It features 24,000 system gates and 608 Logic Elements, supporting up to 140 user-programmable I/O pins. The device integrates up to 2.5 kbits of configurable dual-port SRAM for embedded memory needs. Operating at supply voltages of 3V to 3.6V or 4.75V to 5.25V, it delivers performance up to 250 MHz with a clock-to-out delay of 5.6 ns. Packaged in a 208-pin PQFP, it supports mixed-voltage operation and deterministic timing control.

Feature Summary

• Provides high-density logic capacity with up to 24,000 system gates and 608 LEs for complex digital designs.
• Integrates configurable dual-port SRAM to reduce external memory requirements and simplify board layout.
• Supports mixed-voltage I/O operation compatible with 3.3V and 5.0V standards for flexible system integration.
• Enables deterministic timing through user-controllable delays and 100% pin locking capabilities.

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interfaces and DSP co-processor functions
• Industrial automation and automotive electronic control units

Procurement Notes

Verify component authenticity through authorized Microchip distributors due to the presence of counterfeits in the market. Confirm the specific suffix 'I' indicates industrial temperature range compliance. Check for recent Product Change Notices regarding assembly site updates or software tool modifications that may affect design implementation. Ensure EOL status is considered for long-term production planning.

Selection Notes

Select this model when designing systems requiring moderate logic density with integrated memory resources. Compare against the A42MX36 variant if higher gate counts are necessary. Verify that the 208-pin PQFP package fits the available PCB footprint constraints. Ensure the design utilizes the mixed-voltage I/O capabilities effectively to interface with both 3.3V and 5V peripherals without additional level shifters.

Part Context

This component belongs to the Microchip 40MX and 42MX FPGA families, which succeeded earlier Actel devices. These FPGAs are known for their non-volatile flash technology, eliminating the need for external configuration memories. The family targets applications replacing complex PALs, CPLDs, and standard FPGAs with lower power consumption and faster time-to-market.

Replacement Considerations

Direct replacements include other variants within the A42MX16 series with different packages, such as A42MX16-CQFP172I. For higher capacity needs, the A42MX36 series serves as an upward-compatible option. Cross-reference with older Actel part numbers like ACT42MX16 for legacy design migration.
