24FC256T-I/MS

Memory IC Overview

The Microchip Technology 24FC256T-I/MS is a 32K x 8 (256 Kbit) Serial Electrically Erasable PROM (EEPROM). It operates across a broad voltage range of 1.7V to 5.5V and supports a maximum clock frequency of 1 MHz at VCC ≥ 2.5V. The device features a two-wire I2C compatible interface, hardware write-protect capability, and a 64-byte page write buffer. It is housed in an 8-lead MSOP package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed serial data transmission with a maximum clock frequency of 1 MHz under specified voltage conditions.
• Includes a 64-byte page write buffer to optimize write operations and reduce internal programming cycle overhead.
• Provides hardware-based write protection via the WP pin to prevent unintended data modification.
• Features Schmitt trigger inputs on SDA and SCL lines for enhanced noise suppression.

Memory IC Applications

• Personal communications devices requiring non-volatile data storage
• Data acquisition systems needing reliable parameter retention
• Low-power embedded applications operating on single supply voltages

Memory IC Procurement Notes

Verify that the ordering suffix 'MS' corresponds to the 8-lead MSOP package type required for your PCB layout. Confirm the 'I' designation matches the industrial temperature range specifications (-40°C to +85°C). Ensure the 'T' indicates tape and reel packaging if automated assembly is planned. Cross-reference the specific revision level against your design documentation to guarantee compatibility.

Memory IC Selection Notes

Select this component when a 256 Kbit capacity is required alongside a 1 MHz interface speed. It is suitable for designs needing operation down to 1.7V, unlike the 24LC256 variant which requires a minimum of 2.5V. Consider the MSOP package constraints regarding pin availability for chip select addresses during system architecture planning.

Memory IC Part Context

This part belongs to the 24XX256 family of serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA256 and 24LC256 but offers distinct electrical characteristics, specifically higher clock speeds and lower voltage operation ranges compared to other family members.

Memory IC Replacement Considerations

The 24AA256 serves as a functional substitute but is limited to a 400 kHz maximum clock frequency. The 24LC256 is also interchangeable electrically but requires a minimum supply voltage of 2.5V, whereas this device supports 1.7V operation.
