47L16-E/SN

Overview

The Microchip Technology 47L16-E/SN is a 16Kbit (2K x 8) I2C Serial EERAM device. It operates within a voltage range of 2.7V to 3.6V and supports clock frequencies up to 1 MHz. The component features a word write cycle time of 1 ms and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in an 8-pin SOIC, it integrates SRAM with EEPROM backup for non-volatile data retention.

Feature Summary

• Combines high-speed SRAM performance with non-volatile EEPROM backup capabilities
• Utilizes standard I2C serial interface for simplified system integration
• Designed for operation in extended industrial temperature environments

Applications

• Data logging systems requiring frequent write cycles
• Configuration storage in embedded controllers
• Industrial monitoring devices needing reliable parameter retention

Procurement Notes

Verify the specific suffix 'E/SN' corresponds to the required RoHS compliance and tube packaging configuration. Confirm that the 1 MHz I2C speed meets your system bus requirements. Ensure the 2.7V minimum operating voltage aligns with your power supply design before finalizing procurement.

Selection Notes

Select this component when a solution combining fast random access memory with permanent data storage is required. It is suitable for applications where power loss must not result in data loss, eliminating the need for external battery backups or complex wear-leveling algorithms typically associated with standalone EEPROMs.

Part Context

This part belongs to the 47L16 series of I2C Serial EERAMs manufactured by Microchip Technology. The series provides a unified architecture for low-power, high-reliability memory solutions. The 47L16 variant specifically offers 16Kbit capacity, distinguishing it from smaller density options within the same product family.

Replacement Considerations

The 47C16-E/SN is a confirmed substitute within the same series, offering identical functional specifications and pinout compatibility.
