A42MX16-2TQ176

Overview

The A42MX16-2TQ176 is a Field Programmable Gate Array (FPGA) belonging to the Microsemi 40MX and 42MX families. It features 1890 Configurable Logic Blocks (CLBs) and an equivalent capacity of 24,000 system gates. The device supports a maximum clock frequency of 48.24 MHz with a CLB delay of 3.72 ns. It operates within a voltage range of 4.5 V to 5.5 V and includes up to 2.5 kbits of configurable dual-port SRAM. The component is housed in a 176-pin Thin Quad Flatpack (TQFP) package.

Feature Summary

• Functions as a high-capacity single-chip ASIC alternative capable of consolidating logic from multiple PALs, CPLDs, and FPGAs.
• Supports mixed-voltage operation for both core and I/Os, compatible with 5.0V or 3.3V systems and PCI-compliant interfaces.
• Provides deterministic, user-controllable timing with unique in-system diagnostic and verification capabilities via Silicon Explorer II.

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces
• DSP and co-processor functions

Procurement Notes

Verify the specific suffix against official Microsemi documentation to confirm pinout and electrical characteristics. Ensure compatibility with existing PCB footprints for the TQFP-176 package. Confirm moisture sensitivity level requirements during storage and handling procedures prior to assembly.

Selection Notes

Select this model when design requirements necessitate approximately 24,000 system gates and 1890 CLBs. It is suitable for applications requiring mixed-voltage I/O support and integrated dual-port SRAM. Consider the 176-pin form factor for board space constraints relative to higher pin-count variants.

Part Context

This component is part of the 40MX and 42MX FPGA family, designed to offer cost-effective solutions at 5V. These devices are engineered to shorten system design cycles by replacing multiple discrete programmable logic components with a single high-performance chip.

Replacement Considerations

Direct substitutes include other members of the MX family such as the A42MX24 series for increased gate density or the A42MX08 series for reduced resource requirements. Verify pin-to-pin compatibility and logic capacity before substitution.
