47C04-I/WF16K

Overview

The 47C04-I/WF16K is a static random-access memory (SRAM) device manufactured by Microchip Technology, classified as an EERAM. It features a storage capacity of 4 kbit with an organization of 512 x 8 bits or 2048 x 8 bits. The component operates at a maximum voltage of 5.0V and supports industrial temperature ranges. It utilizes an I2C interface for serial communication.

Feature Summary

Combines SRAM speed with EEPROM non-volatility through integrated backup mechanisms
Provides serial access via standard two-wire I2C protocol
Designed for industrial operating temperature environments

Applications

Industrial control systems requiring persistent data retention
Embedded applications needing fast volatile memory with non-volatile backup
IoT edge devices with limited power cycles

Procurement Notes

Verify the specific memory organization configuration required for your design, as the part may support different bit mappings. Confirm that the wafer-on-frame packaging format aligns with your assembly capabilities, as this is not a standard discrete package. Ensure compatibility with the host controller's I2C voltage levels and timing requirements before finalizing procurement.

Selection Notes

Select this component when both high-speed read/write performance and non-volatile data retention are critical within a single device footprint. It serves as an alternative to separate SRAM and EEPROM combinations, simplifying board layout. Consider the wafer-on-frame form factor constraints during mechanical design and ensure the application environment falls within the specified industrial temperature range.

Part Context

This device belongs to Microchip's 4k/16k I2C Serial EERAM family, which integrates SRAM with EEPROM backup. The 'I' suffix indicates industrial temperature rating, while '/WF16K' denotes the wafer-on-frame packaging style. This series targets applications needing reliable data storage without the write endurance limitations of traditional EEPROMs.
