24LC02BT-I/MNY

Memory IC Overview

The Microchip Technology 24LC02BT-I/MNY is a 2-Kbit (256 x 8) serial EEPROM featuring an I²C interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes an 8-lead TDFN package and functions across an industrial temperature range of -40°C to +85°C. Key electrical parameters include a maximum active read current of 1 mA, standby current of 5 µA at extended temperatures, and a write cycle time of 5 ms.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication compatible with standard I²C protocols
• Includes hardware write protection via the WP pin to inhibit memory writes when tied high
• Features Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination

Memory IC Applications

• Industrial systems requiring non-volatile data storage
• Consumer electronics utilizing low-power microcontrollers
• Automotive applications meeting AEC-Q100 qualification standards

Memory IC Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm the 'I' designation matches required industrial temperature specifications. Ensure the MNY package code corresponds to the 8-TDFN form factor. Validate RoHS compliance status against current manufacturing notifications before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 2.5V minimum supply voltage is acceptable, distinguishing it from lower-voltage variants like the 24AA02. The TDFN package offers a compact surface-mount solution suitable for space-constrained designs. Verify that the 400 kHz bus speed meets system timing requirements compared to higher-speed 1 MHz alternatives.

Memory IC Part Context

This part belongs to the 24XX02 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA02 and 24FC02 but differs in operating voltage and clock frequency capabilities. The 24LC02B series specifically targets applications requiring operation down to 2.5V rather than 1.7V.

Memory IC FAQ

How does the Write Protect (WP) pin function?

Connecting the WP pin to VCC inhibits all write operations, protecting the entire memory array. Connecting it to VSS enables normal read and write access.

What is the page write buffer size?

The device contains an 8-byte page write buffer, allowing up to eight bytes to be written in a single transaction without generating a Stop condition between each byte.
