AT17C256-10CI

Overview

The AT17C256-10CI is a 256Kb serial EEPROM configuration memory device manufactured by Microchip Technology. It operates within a supply voltage range of 4.5V to 5.5V and supports a maximum operating frequency of 12.5 MHz. The component is designed for surface mount installation in an 8-TDFN package. It functions reliably across an extended industrial temperature range from -40°C to +85°C. This non-volatile memory is specifically engineered for FPGA configuration applications, providing robust data retention and high-speed serial access for system initialization.

Feature Summary

• Serial EEPROM architecture optimized for FPGA configuration tasks
• Surface-mount 8-TDFN package design for compact integration
• Industrial temperature rating ensuring reliability in harsh environments

Applications

• Field Programmable Gate Array (FPGA) configuration storage
• System initialization memory for embedded controllers
• Non-volatile data storage in industrial control systems

Procurement Notes

Verify the specific suffix 'CI' confirms the 8-TDFN package and industrial temperature range during procurement. Ensure the ordering documentation explicitly states the 4.5V to 5.5V supply requirement. Confirm RoHS compliance status through official manufacturer channels prior to finalizing orders. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Selection Notes

Select this component when a 256Kb capacity is required for serial configuration of FPGAs or similar programmable logic devices. The 8-TDFN package is suitable for designs prioritizing small footprint and surface-mount assembly. Verify that the system power supply remains strictly within the 4.5V to 5.5V window to prevent operational instability. Consider the -40°C to +85°C range if the application involves variable environmental conditions.
