47C16-E/P

Overview

The Microchip Technology 47C16-E/P is a 16-Kbit SRAM with EEPROM backup, packaged in an 8-pin PDIP. It operates on the I²C interface with a maximum clock frequency of 1 MHz. The device provides non-volatile data storage by automatically transferring SRAM contents to EEPROM upon power loss. It supports extended temperature ranges suitable for automotive applications and complies with RoHS standards.

Feature Summary

• Integrates SRAM with automatic EEPROM backup for non-volatile data retention
• Utilizes I²C serial interface for efficient communication
• Designed for automotive design environments
• Supports extended industrial temperature ranges

Applications

• Automotive electronic systems requiring data retention
• Industrial control devices needing non-volatile memory
• IoT sensors preserving configuration data during power cycles

Procurement Notes

Verify the specific package variant and voltage specifications against the official datasheet before procurement. Confirm that the I²C address and timing requirements align with the system design. Ensure the component meets the required automotive qualification standards if used in vehicle applications. Check for any recent lifecycle status updates or alternative recommendations from the manufacturer.

Selection Notes

Select this component when a small, non-volatile memory solution is needed with minimal pin count. It is suitable for applications where data integrity during power interruptions is critical. Consider the I²C bus speed and pull-up resistor requirements for the target system. Evaluate the trade-off between SRAM speed and EEPROM endurance for the specific use case.

Part Context

This part belongs to the Microchip 47L04/47C04/47L16/47C16 family of I²C Serial EERAMs. These devices combine the speed of SRAM with the non-volatility of EEPROM. The family is recommended for automotive designs, offering a compact memory solution for embedded systems requiring reliable data storage in harsh environments.

Replacement Considerations

Check for direct substitutes within the same EERAM family, such as the 47C04-E/P or 47L16-E/P, depending on capacity needs. Verify pin compatibility and electrical characteristics before substitution.
