AT94S10AL-25BQU

Overview

The AT94S10AL-25BQU is a Field Programmable System Level Integrated Circuit (FPSLIC) from Microchip Technology, combining an 8-bit AVR microcontroller with FPGA fabric. It features 10K FPGA gates and 576 core cells implemented in 0.35um CMOS technology. The device includes 4K to 16K bytes of data SRAM and a 512K x 8 bit EEPROM for code storage. Operating at a maximum speed of 25 MHz, it functions within a voltage range of 3V to 3.6V. The component is housed in a 144-pin LQFP surface-mount package.

Feature Summary

• Integrates an 8-bit AVR microcontroller core with reconfigurable FPGA logic fabric on a single chip
• Provides non-volatile code storage via large embedded EEPROM capacity for system flexibility
• Supports standard digital communication interfaces including I2C and UART for peripheral connectivity

Applications

• Industrial automation control systems requiring mixed signal processing
• Process automation modules needing embedded logic and MCU integration
• High-power module interface controllers

Procurement Notes

Verify the specific suffix 'BQU' corresponds to the 144-pin LQFP package and commercial temperature grade when sourcing. Confirm RoHS compliance status as indicated by manufacturer documentation. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when a design requires both general-purpose processing and custom hardware acceleration without separate chips. The integrated EEPROM allows for field-upgradable logic configurations. Consider the 25 MHz operating speed limit against system timing requirements. Evaluate the 144-pin footprint against available PCB space constraints.
