AT17F040A-30CU

Overview

The AT17F040A-30CU is an FPGA configuration flash memory device manufactured by Microchip Technology, formerly Atmel. It provides 4 Mbit (512K x 8) of non-volatile storage for configuring Field Programmable Gate Arrays. The component operates at a maximum clock frequency of 30 MHz and supports a supply voltage range of 2.7V to 3.6V. It is housed in a 20-pin PLCC package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Provides non-volatile storage for FPGA configuration data
• Supports high-speed serial communication interfaces
• Compatible with standard FPGA programming protocols

Applications

• Configuration of Altera FPGAs
• Configuration of Xilinx FPGAs
• System boot code storage for programmable logic devices

Procurement Notes

Verify the specific speed grade suffix (30) against current datasheet revisions to ensure compatibility with target FPGA timing requirements. Confirm package availability as legacy components may have limited production runs or require alternative sourcing channels through authorized distributors.

Selection Notes

Select this component when designing systems requiring external configuration memory for FPGAs. Ensure the target FPGA supports the specific interface mode (SPI/Parallel) supported by the AT17F series. Verify voltage level compatibility between the microcontroller/FPGA and the 3.3V operation of the flash memory.

Part Context

This part belongs to the AT17F family of configuration memories designed primarily for Altera and Xilinx programmable logic devices. It serves as a persistent storage solution for device configuration bitstreams, allowing FPGAs to load their operational settings automatically upon power-up without host intervention.

Replacement Considerations

Direct substitutes include other members of the AT17F040A series with different speed grades or packages, such as AT17F040A-30JU. Cross-family replacements from other manufacturers may require interface adapter circuits.
