47C04T-I/ST

Overview

The 47C04T-I/ST is a 4-kbit (512 x 8) synchronous EERAM device manufactured by Microchip Technology. It integrates SRAM with EEPROM backup functionality, accessed via an I2C serial interface with a maximum clock frequency of 1 MHz. The component operates within a supply voltage range of 4.5 V to 5.5 V and features a typical access time of 400 ns. It is housed in an 8-pin TSSOP package and supports industrial temperature ranges.

Feature Summary

• Combines volatile SRAM performance with non-volatile EEPROM data retention through automatic background backup mechanisms.

Applications

• Industrial control systems requiring fast data logging
• Embedded applications needing persistent configuration storage
• Data acquisition systems with frequent write cycles

Procurement Notes

Verify the specific suffix 'T' against official Microchip documentation to confirm tape-and-reel packaging status, as standard listings may vary. Ensure the operating voltage requirements align with your system's 4.5V to 5.5V rail specifications before procurement.

Selection Notes

Select this component when high-speed random access is required alongside non-vatility without complex wear-leveling algorithms. It serves as a direct replacement for standard SRAM where power-down data preservation is critical, eliminating the need for external battery backups or slower EEPROM write cycles.

Part Context

This part belongs to the 47x04 family of synchronous EERAMs from Microchip Technology. These devices are designed to bridge the gap between fast volatile memory and slow non-volatile storage, offering seamless data persistence for embedded microcontroller applications in industrial and commercial environments.
