The operating voltage range is specified from 3V to 3.6V, with a nominal voltage of 3.3V. The maximum clock frequency is 25MHz. The component operates within a temperature range of -40°C to +85°C. It is housed in a 208-pin PQFP package measuring 28x28 mm.

Feature Summary

• Integrates FPGA fabric with an embedded 8-bit AVR processor core for combined logic and control capabilities.
• Provides high-density programmable logic through 576 configurable logic blocks.
• Supports standard surface mount installation via a 208-lead plastic quad flatpack package.

Applications

• Complex digital logic implementation requiring embedded processing
• System-on-chip designs combining custom logic with microcontroller functions
• Industrial control applications needing robust programmable interfaces

Procurement Notes

Verify the specific suffix DQU corresponds to the 208-PQFP package and commercial temperature grade when sourcing. Confirm RoHS compliance status as per current manufacturer documentation. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the datasheet revision date to ensure compatibility with design specifications.

Selection Notes

Select this component when a single chip solution is required for both complex gate array logic and sequential control tasks. The integration eliminates the need for separate FPGA and MCU components, reducing board space. Consider the 25MHz performance limit and 3.3V supply requirements against system constraints. Evaluate pin count availability for necessary I/O connections.

Part Context

This part belongs to the AT94K series of FPSLIC devices manufactured by Microchip Technology (formerly Atmel). These devices are designed to accelerate time-to-market by merging reconfigurable logic with established AVR architecture. The series offers scalable gate counts for various application complexities.

Replacement Considerations

The AT94K40AL-25DQU serves as a higher-capacity alternative within the same package and series. Both share identical physical dimensions and pinout configurations, facilitating potential footprint-compatible upgrades if additional logic resources are required.
