AT94K10AL-25AJC

Overview

The AT94K10AL-25AJC is a Field Programmable System Level Integrated Circuit (FPSLIC) combining an Atmel AT40K SRAM-based FPGA with an embedded AVR microcontroller core. It features 10,000 usable FPGA gates and up to 36 Kbytes of dynamically allocated dual-port SRAM for instruction and data storage. The device operates at a maximum clock frequency of 33 MHz within a voltage range of 3.0V to 3.6V. Key specifications include a 25 ns access time, JTAG ICE support for on-chip debugging, and 5V-tolerant I/O structures.

Feature Summary

• Monolithic FPSLIC architecture integrating 10K-gate AT40K FPGA with high-performance 8-bit AVR RISC core
• Up to 36 Kbytes of shared dual-port SRAM (up to 16 Kbytes x 16 program, 16 Kbytes x 8 data)
• JTAG (IEEE 1149.1 compliant) interface with On-Chip ICE support for extensive debug capabilities
• Distributed FreeRAM blocks and Cache Logic for dynamic in-system reconfiguration without data loss

Applications

• Video compression and decompression systems requiring adaptive FIR filters and FFTs
• Portable and handheld applications benefiting from low static and dynamic power consumption
• DSP-based systems utilizing the hardware multiplier and single-clock cycle execution
• Encryption and multimedia convolution applications leveraging FPGA compute-intensive functions

Procurement Notes

Verify the ordering suffix 'JC' against official Microchip documentation to confirm package type and temperature grade. Confirm that the specific revision includes JTAG ICE support as indicated by the datasheet date code conventions. Ensure split power supply layout guidelines are followed during PCB design to support the 3.3V FPGA core and 5V I/O requirements.

Selection Notes

Select this model for designs requiring 10,000 FPGA gates and significant on-chip memory resources. The AT94K10AL supports up to 144 maximum FPGA user I/O lines and 16 programmable AVR I/O lines. Consider the 3.0V-3.6V operating voltage range and 33 MHz PCI-compliant I/O speed when defining system timing constraints.

Part Context

This component belongs to the AT94KAL Series FPSLIC family, which integrates Atmel's AT40K FPGA technology with AVR microcontrollers. The series includes variants with 5K, 10K, and 40K gates. The AT94K10AL specifically provides a balance of logic density and memory capacity, fabricated on a 0.35µm five-layer metal CMOS process.

Replacement Considerations

Compatible alternatives within the same family include the AT94K05AL (5K gates) and AT94K40AL (40K gates). These parts share consistent pin locations and package footprints to facilitate design migration. Verify that any substitute part maintains the required JTAG ICE support and SRAM allocation characteristics.
