47L04T-E/SN

Overview

The Microchip Technology 47L04T-E/SN is a 4-kilobit (4Kbit) synchronous Electrically Erasable Random Access Memory (EERAM) device. It features an I2C serial interface with a maximum clock frequency of 1 MHz and a typical access time of 400 ns. The memory organization is structured as 512 words by 8 bits. Operating within a supply voltage range of 2.7 V to 3.6 V, the component draws a maximum supply current of 400 uA. It supports surface-mount installation in an 8-SOIC package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Combines SRAM speed with EEPROM non-volatility for seamless data retention without power cycles
• Utilizes a standard two-wire I2C serial interface for simplified system integration
• Provides high endurance through unlimited read/write cycles inherent to the EERAM architecture

Applications

• Industrial control systems requiring persistent parameter storage
• Consumer electronics needing reliable configuration data retention
• Automotive modules demanding robust non-volatile memory solutions

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the '-E' designation aligns with the required industrial temperature range specifications. Ensure the I2C address matches the target system design constraints before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring frequent data updates where traditional EEPROM write limits are restrictive. The synchronous I2C interface simplifies timing requirements compared to asynchronous alternatives. Consider the 8-SOIC package dimensions for PCB layout compatibility and thermal management needs.

Part Context

This part belongs to the Microchip 47L04 series of serial EERAM devices. The series integrates fast SRAM performance with non-volatile storage capabilities. It serves as a drop-in replacement for standard SRAM or EEPROM in many embedded designs, offering enhanced reliability and reduced complexity for data logging tasks.

Replacement Considerations

Consult official Microchip documentation for verified cross-reference part numbers. Substitutions must match the I2C interface protocol and voltage specifications.
