34LC02T-I/SN

Overview

The Microchip Technology 34LC02T-I/SN is a 2 Kbit (256 x 8) serial EEPROM featuring an I²C-compatible 2-wire interface. It operates on a single supply voltage ranging from 1.7V to 5.5V and supports clock frequencies up to 1 MHz for the LC version. The device includes permanent and resettable software write-protect capabilities for the lower half of the array, alongside hardware protection via the WP pin. It utilizes low-power CMOS technology with typical standby current of 100 nA and read current of 1 mA. The component offers over one million erase/write cycles and data retention exceeding 200 years.

Feature Summary

• Features permanent and resettable software write-protect mechanisms for the lower half of the memory array.

Applications

• Data storage in industrial electronic systems
• Configuration memory for embedded controllers
• Parameter logging in battery-operated devices

Procurement Notes

Verify that the ordering suffix 'T' corresponds to the specific tape-and-reel packaging configuration required for automated assembly processes. Confirm that the 'I' suffix aligns with the specified industrial temperature range requirements for your application environment. Ensure compatibility with the host system's I²C bus voltage levels and pull-up resistor configurations before finalizing procurement.

Selection Notes

Select this component when a 2 Kbit non-volatile memory solution with high-speed 1 MHz I²C communication is required. It is suitable for designs needing flexible write-protection schemes through both software commands and hardware pins. Consider its wide operating voltage range and low power consumption for portable or energy-efficient applications requiring reliable long-term data retention.

Part Context

This part belongs to the 34AA02/34LC02 family of serial EEPROMs manufactured by Microchip Technology. The 'LC' designation indicates support for higher clock speeds compared to the standard AA variant. The 'SN' suffix identifies the 8-lead SOIC surface-mount package type, while 'T' denotes reel packaging. This family provides robust noise suppression and brown-out detection features.

Replacement Considerations

The 34LC02BT-I/SN serves as a verified replacement within the same product family, offering identical electrical characteristics and functionality.
