24C00T-E/OT

Memory IC Overview

The Microchip Technology 24C00T-E/OT is a serial electrically erasable programmable read-only memory (EEPROM) device featuring a storage capacity of 128 bits, organized as 16 words by 8 bits. It utilizes a 2-Wire I2C interface with a maximum clock frequency of 400 kHz. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports surface mount installation in an SOT-23-5 package. Key electrical parameters include a typical access time of 3.5 µs, a maximum active read current of 2 mA, and a working supply current of 500 µA. Data retention is specified at 200 years.

Memory IC Feature Summary

• Supports high-speed I2C communication with a maximum clock frequency of 400 kHz for efficient data transfer.
• Provides long-term non-volatile data storage with a verified retention period of 200 years.
• Operates reliably across an extended industrial temperature range from -40°C to +125°C.

Memory IC Applications

• Embedded systems requiring small-scale non-volatile configuration storage
• Industrial control devices needing parameter retention under extreme temperatures
• Consumer electronics utilizing I2C-based memory for calibration data

Memory IC Procurement Notes

Verify the specific suffix OT confirms the SOT-23-5 package and tape-and-reel shipping format. Confirm the E suffix indicates the extended temperature grade (-40°C to +125°C). Ensure compatibility with 5V logic levels, as this variant does not support lower voltage operation compared to other family members. Check RoHS compliance status via official documentation before finalizing procurement.

Memory IC Selection Notes

Select this part when a compact SOT-23-5 footprint is required for 128-bit EEPROM applications. It is suitable for designs operating strictly at 5V, unlike wider voltage variants. Consider the 400 kHz speed limit if higher throughput is needed, in which case the 24FC series might be more appropriate. Verify that the 3.5 µs access time meets system timing requirements.

Memory IC Part Context

This component belongs to the Microchip 24C00 family of serial EEPROMs. It shares the same memory architecture and interface protocol with variants like the 24C00-I/SN but differs in packaging and temperature rating. The T suffix typically denotes tape-and-reel packaging, while OT specifies the SOT-23-5 form factor with extended temperature capabilities.

Memory IC Replacement Considerations

Publicly confirmed substitutes include the 24C00T-I/ST for standard temperature SOT-23-5 applications and the 24C00T-E/MNY for TDFN-8 packaging. Cross-reference datasheets to ensure voltage and speed specifications match the original design requirements.
