34VL02/MS

Overview

The Microchip Technology 34VL02/MS is a 2 Kbit (256 x 8) serial EEPROM operating within a supply voltage range of 1.5V to 3.6V. It features a 2-wire I²C compatible interface with maximum clock frequencies of 100 kHz at voltages below 1.8V and 400 kHz at voltages between 1.8V and 3.6V. The device supports page writes of up to 16 bytes, has a typical write cycle time of 3 ms, and offers data retention exceeding 200 years. It is housed in an 8-lead MSOP package.

Feature Summary

• Features permanent and resettable software write-protect capabilities for the lower half of the memory array alongside hardware protection for the entire array via the WP pin.
• Incorporates Schmitt trigger inputs and output slope control to suppress noise spikes and eliminate ground bounce during operation.
• Supports cascading of up to eight devices on the same bus using chip select bits A0, A1, and A2.

Applications

• Low-voltage embedded systems requiring non-volatile data storage
• Industrial applications utilizing I²C communication protocols
• Battery-powered devices necessitating low standby current consumption

Procurement Notes

Verify that the ordering suffix corresponds to the MSOP package type as specified. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the selected variant matches the required temperature range specifications for the intended operational environment.

Selection Notes

Select this component when a 2 Kbit capacity is required with flexible write-protection options. Consider the 1.5V minimum operating voltage for low-power designs. Verify compatibility with the system's I²C bus speed requirements, noting the frequency limitation below 1.8V supply voltage.

Part Context

The 34VL02 belongs to the 34VLxx series of serial EEPROMs manufactured by Microchip Technology. This series provides electrically erasable programmable read-only memory solutions designed for applications requiring reliable data retention and low power consumption across a wide voltage range.

Replacement Considerations

Consult the official datasheet for cross-reference information regarding equivalent parts from other manufacturers or alternative packages within the same product family.
