AT94K10AL-25AQI

Overview

The AT94K10AL-25AQI 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 for the AVR core. Fabricated using a 0.35µm CMOS process, it supports PCI-compliant 3.3V I/O structures and includes extensive peripherals such as UARTs, timers, and a hardware multiplier.

Feature Summary

• Monolithic FPSLIC architecture integrating AT40K FPGA (10K gates) with AVR 8-bit RISC microcontroller
• Up to 36 Kbytes of shared dual-port SRAM for program and data storage
• On-chip JTAG ICE for comprehensive debugging and boundary-scan capabilities
• High-performance DSP optimized core cell with 8-sided array multipliers and Cache Logic

Applications

• Video compression and decompression systems requiring adaptive filtering
• Encryption and convolution algorithms utilizing DSP-optimized logic
• Portable and handheld applications benefiting from low static and dynamic power consumption
• Systems requiring dynamic reconfigurable in-system logic via Cache Logic

Procurement Notes

Verify the specific ordering suffix AQI against the manufacturer's current datasheet to confirm package type and temperature range. Ensure design layouts support split power supplies for VCC and VCCIO as recommended for AT94KAL devices. Confirm RoHS compliance status through official Microchip or Atmel documentation prior to procurement.

Selection Notes

Select this component when a combined FPGA and microcontroller solution is required to reduce board space and complexity. The AT94K10AL offers 10K gates, suitable for moderate logic density designs. Consider the 25MHz speed grade if real-time processing constraints exist. Verify that the 3.0V-3.6V operating voltage aligns with the system power rails, as this series does not support 5V operation directly.

Part Context

The AT94K10AL belongs to the AT94KAL Series FPSLIC family, which merges Atmel's AT40K FPGA technology with AVR microcontroller cores. This series is designed for rapid prototyping and production in applications needing both programmable logic and control processing. The 'J' designation in date codes indicates JTAG ICE support, a key feature for development and debugging workflows.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitutes within the AT94KAL family, such as the AT94K05AL or AT94K40AL, depending on gate count requirements. Ensure any replacement maintains the same package footprint and electrical specifications, particularly the 3.3V PCI-compliant I/O levels.
