AT94K10AL-25BQI

Overview

The AT94K10AL-25BQI is a monolithic 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 instruction and data SRAM. 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 0.35µm CMOS process, JTAG ICE support for on-chip debugging, and 5V I/O tolerance. The architecture supports dynamic reconfiguration via Cache Logic and includes extensive peripherals such as UARTs, timers, and a hardware multiplier.

Feature Summary

• Integrated FPSLIC architecture with 10K FPGA gates and high-performance 8-bit RISC AVR core
• Up to 36 Kbytes of shared dual-port SRAM for flexible program and data allocation
• JTAG (IEEE 1149.1) interface with On-Chip In-Circuit Emulator (ICE) support
• Dynamic reconfigurable logic (Cache Logic) allowing in-system FPGA updates without data loss

Applications

• Portable and handheld applications requiring low static and dynamic power consumption
• DSP-optimized systems utilizing the hardware multiplier and fast array multipliers
• Multimedia applications including video compression/decompression and encryption
• Adaptive logic designs leveraging dynamic partial reconfiguration capabilities

Procurement Notes

Verify the presence of JTAG ICE support by checking the date code suffix 'J' on the component marking. Ensure PCB layout accommodates split power supply requirements for the FPGA and AVR sections. Confirm RoHS compliance status through official manufacturer documentation prior to procurement.

Selection Notes

Select this model for designs requiring 10,000 FPGA gates and integrated microcontroller control. Compare against AT94K05AL for lower gate counts or AT94K40AL for higher density. Ensure the design utilizes the 3.0V-3.6V operating voltage range and leverages the 5V tolerant I/O structures for mixed-voltage interfaces.

Part Context

This component belongs to the AT94KAL Series FPSLIC family, which integrates Atmel's AT40K FPGA technology with AVR microcontrollers. The series is fabricated using a 0.35µm five-layer metal CMOS process. It is designed to reduce time-to-market by providing co-verification tools and supporting automatic component generators for efficient FPGA design implementation.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Design migration within the same package footprint is supported by other members of the AT94K series, specifically the AT94K05AL and AT94K40AL, which maintain consistent pin locations.
