• Supports mixed-voltage operation for core and I/Os with PCI-compliant interfaces
• Enables deterministic, user-controllable timing and up to 100% pin locking

Applications

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

Procurement Notes

Verify the specific revision level and manufacturing date code against the latest Microchip datasheet before procurement. Confirm that the PLCC-84 package variant matches the required footprint for your PCB layout. Ensure compliance with RoHS directives if applicable to your assembly process. Check for any recent Product Change Notifications regarding component availability or material composition updates.

Selection Notes

Select this model when a cost-effective 5V solution is required for consolidating logic previously implemented in multiple PALs or CPLDs. Consider the A42MX series for designs needing fast wide-decode circuitry and dual-port SRAM capabilities. Evaluate the 336 LE capacity against your logic density requirements to ensure optimal resource utilization without over-specifying the device.
