47C16T-E/SN

Overview

The Microchip Technology 47C16T-E/SN is a non-volatile EERAM (Electrically Erasable and Readable Memory) integrated circuit. It combines a 16Kbit SRAM with EEPROM backup functionality, designed for automotive applications. The device features an I2C interface with a maximum clock frequency of 1 MHz and an access time of 400 ns. It operates within a supply voltage range of 2.5 V to 5.5 V and is housed in an 8-pin SOIC package.

Feature Summary

• Integrates SRAM with EEPROM backup for non-volatile data retention
• Supports automotive application environments
• Utilizes I2C serial communication interface

Applications

• Automotive electronic systems requiring non-volatile memory
• Data logging applications needing fast read/write speeds
• Embedded systems with power loss protection requirements

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging versus tube options. Confirm RoHS compliance status through official datasheets. Ensure the component meets automotive qualification standards if required for your design. Cross-reference the exact part number with manufacturer documentation to avoid confusion with similar variants like the 47C16-E/SN.

Selection Notes

Select this component when both high-speed SRAM performance and non-volatile storage are needed without external battery backup circuits. Consider the I2C interface compatibility with your microcontroller. Evaluate the operating temperature range against your environmental constraints. Compare power consumption specifications with alternative EERAM solutions.

Part Context

This part belongs to Microchip's family of EERAM devices, which merge SRAM speed with EEPROM persistence. It serves as a drop-in replacement for standard SRAM in applications where data retention during power cycles is critical. The 16Kbit capacity provides sufficient storage for configuration data or small datasets in compact embedded designs.

Replacement Considerations

Check for direct substitutes such as the 47C16-E/SN, noting differences in packaging. Verify pinout compatibility before substitution. Ensure any replacement maintains the same I2C address and timing characteristics.
