47L04-I/P

Overview

The Microchip Technology 47L04-I/P is a 4 kbit Electrically Erasable RAM (EERAM) device organized as 512 words by 8 bits. It features an I2C serial interface with a maximum clock frequency of 1 MHz and an access time of 400 ns. The component operates within a supply voltage range of 2.7 V to 3.6 V, with a maximum power consumption of 400 uA. It supports through-hole installation in a PDIP-8 package and functions reliably across an industrial temperature range from -40°C to +125°C.

Feature Summary

• Combines SRAM speed with non-volatile data retention via integrated Ferroelectric memory technology
• Enables direct I2C serial communication for simplified system integration
• Operates effectively at elevated temperatures up to 125°C

Applications

• Industrial control systems requiring persistent data storage
• Embedded applications needing frequent parameter updates
• Sensor data logging in harsh environments

Procurement Notes

Verify the specific suffix 'I/P' confirms the industrial temperature grade (-40°C to +125°C) and PDIP-8 through-hole package. Confirm the datasheet revision matches the required specifications for I2C compatibility and voltage levels. Ensure the ordering code aligns with the manufacturer's current production status before finalizing procurement.

Selection Notes

Select this component when non-volatile storage is required without the complexity of flash programming cycles. The I2C interface reduces pin count compared to parallel alternatives. Consider the PDIP-8 package for prototyping or through-hole manufacturing needs. Verify that the 400 ns access time meets the system timing requirements.

Part Context

This part belongs to the Microchip 47L04 series of EERAM devices. These components utilize Ferroelectric technology to provide unlimited endurance for write cycles. The series offers a robust alternative to traditional EEPROM and Flash memory solutions in applications demanding high reliability and fast write speeds.

Replacement Considerations

Consult official substitution lists for compatible variants such as the 47L04-E/P for commercial temperature grades or other packages like SOIC. Cross-reference electrical parameters to ensure interface and voltage compatibility.
