AT94S10AL-25BQI

FPGAs (Field Programmable Gate Array) With Microcontrollers Overview

The AT94S10AL-25BQI is a Secure Field Programmable System Level Integrated Circuit (FPSLIC) from Microchip Technology, housed in a 144-pin LQFP package. It integrates an AT40K SRAM-based FPGA with 10,000 usable gates and an embedded AVR 8-bit RISC microcontroller. The device includes 1 Mbit of secure configuration EEPROM memory for ISP and security protection. Operating at a supply voltage of 3.0V to 3.6V, it supports up to 137 FPGA user I/O lines and 16 programmable AVR I/O lines. Key features include Cache Logic for dynamic reconfiguration, JTAG debug support, and hardware multipliers for DSP applications.

FPGAs (Field Programmable Gate Array) With Microcontrollers Procurement Notes

Verify the specific suffix 'BQI' corresponds to the 144-pin LQFP package and industrial temperature range (-40°C to +85°C) as defined in the manufacturer's part numbering guide. Confirm that the source document explicitly lists this exact part number variant, as generic family datasheets may not detail every packaging option. Ensure compatibility with the required 3.3V operating voltage and 5V tolerant I/O levels for your target system design.

FPGAs (Field Programmable Gate Array) With Microcontrollers Selection Notes

Select the AT94S10AL-25BQI when 10,000 FPGA gates are sufficient for the logic implementation alongside an embedded AVR controller. Compare against the AT94S05AL for lower gate counts or the AT94S40AL for higher capacity (40K gates). Consider the 144-pin LQFP package constraints if board space is limited. Verify that the 1 Mbit configuration memory meets the size requirements for both FPGA bitstream and AVR application code storage.

FPGAs (Field Programmable Gate Array) With Microcontrollers Part Context

This component belongs to the AT94S Secure FPSLIC family, which merges Atmel's AT40K FPGA technology with AVR microcontrollers and AT17 series EEPROMs. The 'AT94S10AL' designation indicates the 10K gate variant within this multi-chip module architecture. The 'BQI' suffix typically denotes the 144-pin LQFP package and industrial temperature rating, distinguishing it from BGA packages or commercial temperature variants found in the broader AT94S series.

FPGAs (Field Programmable Gate Array) With Microcontrollers Replacement Considerations

Direct pin-to-pin replacements within the same package are limited to other AT94S series devices like the AT94S05AL or AT94S40AL, provided gate count and I/O requirements align. Cross-family replacements require significant redesign due to the unique integration of FPGA and AVR cores. No alternative part numbers are confirmed in the provided documentation.
