47L16-I/P

Overview

The Microchip Technology 47L16-I/P is a static random access memory component belonging to the EERAM family. It features a storage capacity of 16 kbit organized as 2k x 8 bits. The device utilizes an I2C interface and supports a maximum clock frequency of 1 MHz. Operating voltage ranges from a minimum of 2.7 V to a maximum of 3.6 V, with a maximum power consumption of 400 uA. It is housed in an 8-pin PDIP package designed for through-hole mounting. The component operates within an industrial temperature range of -40°C to +125°C.

Feature Summary

• Combines SRAM speed with non-volatile data retention capabilities
• Supports standard I2C communication protocol
• Operates reliably across extended industrial temperature ranges

Applications

• Industrial control systems requiring persistent data storage
• Embedded sensor networks needing configuration retention
• Automotive electronics operating in harsh thermal environments

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature grade. Ensure compatibility with existing I2C bus voltage levels before integration. Confirm availability status directly with authorized distributors as supply conditions may vary. Validate RoHS compliance requirements for your specific manufacturing region.

Selection Notes

Select this component when non-volatile storage is required without complex write-erase cycles typical of flash memory. The I2C interface simplifies PCB routing compared to parallel alternatives. Consider the 16 kbit capacity relative to system data logging needs. Verify that the 3.6 V maximum voltage aligns with the target system power supply rails.

Part Context

This part belongs to the Microchip 47Lxx series of Electrically Erasable RAM devices. These components bridge the gap between volatile SRAM and slower non-volatile memories by offering byte-level accessibility with permanent data retention. The series is designed for applications demanding high endurance and low power consumption in compact packages.

Replacement Considerations

Direct substitutes include other members of the 47Lxx series such as the 47L04 or 47L32, provided pinout and capacity requirements are met. Cross-reference with 47Cxx variants if commercial temperature grades are acceptable instead of industrial ratings.
