AT94S10AL-25DGI

Overview

The AT94S10AL-25DGI is a Field Programmable System Level Integrated Circuit (FPSLIC) combining an Atmel AT40K SRAM-based FPGA with an embedded AVR microcontroller and secure configuration EEPROM. It features 10,000 FPGA gates, up to 32 Kbytes of instruction SRAM, and up to 16 Kbytes of data SRAM. The device operates at a maximum frequency of 25 MHz with a supply voltage range of 3.0V to 3.6V. It includes a 1 Mbit configuration memory with security protection and in-system programming capabilities.

Feature Summary

• Integrated AT40K SRAM-based FPGA with 10,000 usable gates and Cache Logic capability
• Embedded high-performance 8-bit AVR RISC microcontroller core
• Up to 32 Kbytes of dynamically allocated instruction SRAM and 16 Kbytes of data SRAM
• 1 Mbit Secure Configuration EEPROM with In-System Programming (ISP)
• JTAG (IEEE Std. 1149.1 Compliant) interface for on-chip debug support

Applications

• Portable and handheld applications requiring low power consumption
• DSP-based systems utilizing the hardware multiplier
• Secure embedded systems requiring configuration memory protection
• Industrial control systems using integrated UARTs and timers

Procurement Notes

Verify the specific ordering suffix 'DGI' against official Microchip/Atmel documentation to confirm package type and temperature grade. Ensure compatibility with the required 3.0V to 3.6V supply voltage. Confirm that the 25MHz speed grade meets system timing requirements. Check for RoHS compliance status if required by local regulations.

Selection Notes

Select this component when a combined FPGA and microcontroller solution is needed to reduce board space. The AT94S10AL offers a balance between logic capacity (10K gates) and processing power. Consider the AT94S05AL for lower gate counts or the AT94S40AL for higher performance needs. Ensure the design supports the 3.3V PCI-compliant I/O structures.

Part Context

The AT94S series belongs to the Secure FPSLIC family, merging Atmel's AT40K FPGA technology with AVR microcontrollers and AT17 Series configuration memories. This integration allows for dynamic reconfiguration and secure booting. The device utilizes a patented SRAM-based architecture with FreeRAM technology for flexible memory allocation.
