34LC02T-E/MS

Overview

The Microchip Technology 34LC02T-E/MS is a 2 Kbit (256 x 8) serial EEPROM housed in an 8-lead MSOP package. It operates on a single supply voltage ranging from 1.7V to 5.5V and supports a maximum clock frequency of 1 MHz. The device features a 2-wire I2C compatible interface, low-power CMOS technology with typical standby current of 100 nA, and extended temperature range operation from -40°C to +125°C.

Feature Summary

• Supports permanent and resettable software write-protect for the lower half of the memory array
• Includes hardware write protection capability via the dedicated WP pin
• Features Schmitt trigger inputs for enhanced noise suppression

Applications

• Embedded systems requiring non-volatile data storage
• Industrial control applications operating in extended temperature environments
• Automotive electronic modules

Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape-and-reel packaging and '/MS' indicates the MSOP package type. Confirm the 'E' suffix matches the required automotive temperature range (-40°C to +125°C). Ensure compatibility with the system's I2C bus voltage levels and check for specific RoHS compliance documentation if required by the manufacturing process.

Selection Notes

Select this component when a 2 Kbit capacity is sufficient and high-speed 1 MHz operation is required. It is suitable for designs needing flexible write-protection schemes or robust performance in electrically noisy environments. Consider the MSOP package dimensions against available PCB space constraints.

Part Context

This part belongs to the 34XX02 family of serial EEPROMs, which includes the 34AA02 variant. The 34LC02 specifically offers higher clock speed capabilities compared to standard variants. It is designed for applications demanding reliable data retention and low power consumption across a wide voltage range.

Replacement Considerations

The 34AA02T-E/MS serves as a functional substitute within the same family, though it has a lower maximum clock frequency specification.
