AT94K10AL-25AQC

Overview

The AT94K10AL-25AQC is a Field Programmable System Level Integrated Circuit (FPSLIC) combining an AT40K SRAM-based FPGA with an embedded AVR 8-bit RISC microcontroller. It features 10,000 FPGA gates, up to 36 Kbytes of shared dual-port SRAM, and JTAG ICE support for on-chip debugging. The device operates at 3.0V to 3.6V, supports 33 MHz PCI-compliant I/O, and utilizes a 0.35µm CMOS process. Key capabilities include dynamic reconfiguration via Cache Logic, hardware multipliers for DSP applications, and extensive peripheral integration within a monolithic architecture.

Feature Summary

• Monolithic FPSLIC architecture integrating AT40K FPGA and AVR RISC core
• 10,000 usable FPGA gates with distributed FreeRAM and Cache Logic
• Up to 36 Kbytes of dynamically allocated instruction and data SRAM
• On-chip JTAG ICE support for comprehensive debug and boundary-scan

Applications

• Video compression and decompression systems
• Encryption and convolution algorithms
• Adaptive finite impulse response (FIR) filters
• Fast Fourier transforms (FFT) and discrete-cosine transforms (DCT)

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Confirm JTAG ICE support availability by checking the date code marking for the 'J' indicator as described in the datasheet. Ensure PCB design accounts for split power supply requirements for optimal performance.

Selection Notes

Select this component when system design requires tight integration between programmable logic and microcontroller processing without external interconnects. The AT94K10AL offers a balance of gate density and memory resources suitable for complex control and signal processing tasks. Consider the 3.3V operating voltage and 5V I/O tolerance for interface compatibility with standard logic levels.

Part Context

This part belongs to the AT94KAL Series, which includes variants with 5K, 10K, and 40K gates. The 'AL' designation indicates the 3.0V–3.6V operating voltage range. The series is fabricated using Atmel’s 0.35µ five-layer metal CMOS process, providing high performance and low power consumption compared to earlier generations.

Replacement Considerations

Direct pin-compatible replacements within the same family include the AT94K05AL and AT94K40AL, subject to gate and memory resource requirements. Verify that any substitute maintains the required JTAG ICE support and voltage specifications.
