A42MX09-2PLG84

Overview

The A42MX09-2PLG84 is a Field Programmable Gate Array from the Microchip A42MX series, housed in an 84-pin PLCC package. It provides 14,000 system gates and 336 logic elements with 72 I/O pins. The device operates on a supply voltage range of 4.75 V to 5.25 V and supports functional levels at 3.3 V and 5 V. It is rated for commercial temperature operation between 0°C and +70°C.

Feature Summary

• Single-chip ASIC alternative offering high performance and cost-effective design solutions
• Supports mixed-voltage operation with PCI-compliant I/Os
• Enables up to 100% resource utilization and pin locking
• Features deterministic, user-controllable timing

Applications

• High-speed controllers
• Address decoding
• Peripheral bus interfaces
• DSP functions
• Co-processor applications

Procurement Notes

Verify component authenticity through authorized Microchip distributors or official channels. Confirm RoHS compliance status via current datasheets. Check for moisture sensitivity handling requirements during storage and assembly. Validate that the specific suffix matches the required package and temperature grade for your application.

Selection Notes

Select this model when 14,000 system gates are sufficient for the design. Ensure the 84-pin PLCC package fits the PCB layout constraints. Verify that the 5V core voltage requirement aligns with the system power architecture. Consider the commercial temperature range limits for environmental suitability.

Part Context

This component belongs to the A42MX family of FPGAs, which serves as a single-chip solution to consolidate logic previously implemented in multiple PALs, CPLDs, and FPGAs. The family offers configurable dual-port SRAM and fast wide-decode circuitry to shorten system development cycles.

Replacement Considerations

Check for direct cross-references within the A42MX series such as A42MX09 variants with different packages. Evaluate newer Microchip FPGA families if long-term availability is critical, as older MX series parts may face discontinuation.
