A42MX16-1PL84M

Overview

The A42MX16-1PL84M is a Field Programmable Gate Array (FPGA) from the MX series, manufactured by Microchip Technology. It features 24,000 system gates and supports 72 I/O pins within an 84-LCC (J-Lead) package. The device operates on supply voltages of 3V to 3.6V or 4.5V to 5.5V. It is rated for an operating temperature range of -55°C to 125°C (TC). The component is classified as obsolete with a RoHS status of non-compliant.

Feature Summary

• Single-chip ASIC alternative providing high performance while shortening design cycles
• Supports mixed-voltage operation for core and I/Os with PCI-compliant interfaces
• Enables up to 100% resource utilization and 100% pin locking

Applications

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

Procurement Notes

Verify obsolescence status before procurement as the part is marked obsolete. Confirm voltage requirements match specific operational needs due to dual supply options. Check RoHS compliance constraints for regulatory adherence. Ensure packaging type matches board layout specifications.

Selection Notes

Select this model for applications requiring 24,000 system gates in a compact 84-pin package. Consider the wide industrial and military temperature range for harsh environments. Evaluate the need for mixed-voltage support if interfacing with different logic levels. Verify that the J-Lead package is suitable for the intended mounting method.

Part Context

This component belongs to the Microchip MX FPGA family, designed as a cost-effective solution for consolidating logic previously implemented in multiple PALs, CPLDs, and FPGAs. The family offers deterministic timing and in-system diagnostic capabilities via Silicon Explorer II.
