47L16T-I/ST

Overview

The Microchip Technology 47L16T-I/ST is a 16-kbit (2K x 8) Electrically Erasable RAM (EERAM) device housed in an 8-pin TSSOP package. It operates within a voltage range of 2.7 V to 3.6 V and supports industrial temperatures from -40°C to +85°C. The component utilizes a synchronous I2C interface with a maximum clock frequency of 1 MHz, providing non-volatile data retention without the latency associated with traditional flash memory.

Feature Summary

• Integrates SRAM speed with EEPROM non-volatility for instant data persistence
• Supports standard I2C communication protocols for simplified system integration
• Eliminates complex write cycles and erase requirements found in conventional flash

Applications

• Industrial sensor data logging systems
• Real-time clock backup memory modules
• Configuration storage in embedded controllers

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the '-I' designation aligns with required industrial temperature specifications. Cross-reference the manufacturer part number against official datasheets to ensure compatibility with existing PCB footprints and voltage levels before finalizing procurement.

Selection Notes

Select this component when design requirements demand high-speed random access combined with non-volatile storage capabilities. It serves as a direct replacement for volatile SRAM where power loss data retention is critical. Ensure the host controller supports the necessary I2C timing constraints and address configurations defined in the technical documentation.

Part Context

This device belongs to the 47L16 series of EERAM products manufactured by Microchip Technology. These components are designed to bridge the performance gap between fast volatile memory and slower non-volatile alternatives, offering a compact solution for applications requiring frequent data updates without wear-leveling concerns.

Replacement Considerations

Check for compatible variants such as the 47L04T-I/ST for smaller capacity needs or the 47L16-I/ST if tube packaging is preferred over tape-and-reel.
