AT94K10AL-25AJI

Overview

The AT94K10AL-25AJI is a monolithic Field Programmable System Level Integrated Circuit (FPSLIC) combining an Atmel AT40K SRAM-based FPGA with an embedded high-performance RISC AVR microcontroller core. It features 10,000 usable FPGA gates, up to 36 Kbytes of dynamically allocated instruction and data SRAM, and on-chip JTAG ICE support. The device operates at a supply voltage of 3.0V to 3.6V with a maximum clock frequency of 25 MHz. It utilizes a 0.35µm CMOS five-layer metal process and includes extensive peripherals such as two UARTs, timer/counters, and a hardware multiplier.

Feature Summary

• Monolithic integration of 10K-gate AT40K FPGA and 8-bit AVR RISC microcontroller
• Up to 36 Kbytes of shared dual-port SRAM for program and data storage
• On-chip JTAG ICE for comprehensive debug and boundary-scan capabilities
• Distributed FreeRAM with 10 ns access time and Cache Logic for dynamic reconfiguration

Applications

• Video compression and decompression systems requiring DSP functions
• Encryption and convolution algorithms for multimedia applications
• Portable and handheld devices due to low static and dynamic power consumption
• Adaptive logic designs utilizing dynamic full or partial logic reconfiguration

Procurement Notes

Verify the presence of the 'J' suffix in the date code to confirm JTAG ICE support, as indicated by the manufacturer's identification scheme. Ensure PCB layout supports split power supplies for the FPGA and AVR cores. Confirm RoHS compliance status through official Microchip documentation prior to procurement.

Selection Notes

Select this model for designs requiring 10,000 FPGA gates and significant on-chip memory resources. The 25MHz speed grade suits moderate-frequency processing tasks. Consider the ATFS10 support device if external configuration memory is required for power-up loading. Verify that the 3.0V-3.6V operating voltage range aligns with the system power architecture.
