AT94K10AL-25BQC

Overview

The AT94K10AL-25BQC is a monolithic Field Programmable System Level Integrated Circuit (FPSLIC) combining an Atmel AT40K SRAM-based FPGA with an embedded high-performance AVR 8-bit RISC microcontroller. It features 10,000 FPGA gates, up to 32 Kbytes of dynamically allocated instruction and data SRAM, and JTAG ICE support. The device operates at a maximum clock frequency of 33 MHz with a supply voltage range of 3.0V to 3.6V. Key specifications include 576 FPGA core cells, 4096 bits of FPGA SRAM, and 846 total registers.

Feature Summary

• Monolithic FPSLIC architecture integrating AT40K FPGA with AVR Enhanced RISC Core
• 10,000 usable FPGA gates with Cache Logic for dynamic reconfiguration
• Up to 32 Kbytes of shared dual-port SRAM (Instruction and Data)
• JTAG (IEEE std. 1149.1 Compliant) Interface with On-chip ICE support

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 ordering suffix 'BQC' against official Microchip documentation to confirm package type and temperature grade. Confirm that the specific date code includes the 'J' indicator for JTAG ICE support if debug functionality is required. Ensure split power supply layout guidelines are followed during PCB design as recommended in the application notes.

Selection Notes

Select this model for applications requiring 10,000 FPGA gates and an embedded 8-bit microcontroller. It is suitable for designs needing dynamic logic reconfiguration via Cache Logic. Compare against AT94K05AL for lower gate counts or AT94K40AL for higher density. Ensure the system voltage matches the 3.0V - 3.6V operating range.

Part Context

This component belongs to the AT94KAL Series FPSLIC family, which integrates SRAM-based FPGAs with AVR microcontrollers. The series includes AT94K05AL, AT94K10AL, and AT94K40AL variants. These devices are fabricated on a 0.35µ CMOS five-layer metal process and utilize the AT40K FPGA core architecture.

Replacement Considerations

Direct replacements within the same family include the AT94K05AL (5K gates) and AT94K40AL (40K gates). Verify pin compatibility and memory allocation differences before substitution. Other FPSLIC families like AT94SAL use different technology and may require design changes.
