24FC04T-E/OT36KVAO

Memory IC Overview

The Microchip Technology 24FC04T-E/OT36KVAO is a 4-Kbit Electrically Erasable PROM organized as two blocks of 256 x 8-bit memory. It features a 2-wire serial I2C interface with a maximum clock frequency of 1 MHz across the full operating voltage range of 1.7V to 5.5V. The device supports page writes up to 16 bytes and includes hardware write protection via the WP pin. It is qualified under AEC-Q100 standards for automotive applications, operates within an extended temperature range of -40°C to +125°C, and utilizes a 5-lead SOT-23 surface-mount package.

Memory IC Feature Summary

• AEC-Q100 qualified for automotive reliability requirements
• Extended temperature operation from -40°C to +125°C at low voltages
• Hardware write protection enabled by connecting the WP pin to VCC
• Schmitt trigger inputs provide noise suppression on the serial bus

Memory IC Applications

• Automotive electronic control units requiring non-volatile data storage
• Industrial systems operating in high-temperature environments
• Low-voltage embedded devices utilizing I2C communication protocols

Memory IC Procurement Notes

Verify that the specific suffix '36KVAO' corresponds to the intended reel or cut tape packaging configuration as defined by the manufacturer's ordering guide. Confirm the component meets the required AEC-Q100 qualification level for your specific application environment. Ensure the extended temperature grade (E) matches your system's thermal specifications before finalizing procurement.

Memory IC Selection Notes

Select this component when an I2C EEPROM requires operation below 2.5V while maintaining a 1 MHz clock speed. The 24FC04 series is distinct from the 24LC04B, which is limited to 400 kHz and higher minimum voltages. Choose this part if the design necessitates the specific 5-lead SOT-23 footprint combined with automotive-grade durability and extended temperature tolerance.

Memory IC Part Context

This part belongs to the 24XX04 family of 4-Kbit serial EEPROMs manufactured by Microchip Technology. The family includes variants such as the 24AA04 and 24LC04B, which differ primarily in maximum clock frequency and minimum operating voltage. The 24FC04 variant specifically bridges the gap between low-voltage compatibility and high-speed serial communication capabilities.

Memory IC Replacement Considerations

The 24FC04T-E/OT is the direct functional equivalent to the standard 24FC04T-E/OT. Verify that any substitute maintains the 1 MHz clock specification and the -40°C to +125°C temperature range, as lower-grade industrial versions may not support the required performance envelope.
