Overview

The MB85RS16NPN-G-AMEWE1 is a 16Kbit (2K x 8) non-volatile Ferroelectric RAM (FRAM) memory IC. It features a high-speed SPI interface with a clock frequency up to 20 MHz and operates from a supply voltage range of 2.7V to 3.6V. This FRAM offers advantages over traditional EEPROM or Flash memory by providing faster write speeds and higher endurance.

Why Choose This Part

This FRAM offers unlimited read/write endurance and significantly faster write times compared to EEPROM or Flash, making it suitable for applications requiring frequent data logging. Its non-volatile nature ensures data retention without the need for a battery, and its low operating and standby currents make it efficient for power-sensitive designs. The SPI interface simplifies integration into many embedded systems.

Applications

Industrial Control Systems
Used for logging configuration settings, error codes, and operational data that must persist through power cycles without the latency or wear concerns of other non-volatile memory types.
Metering Devices
Ideal for energy meters, water meters, and gas meters to store critical billing data and tamper detection logs due to its high write endurance and low power consumption.
Medical Devices
Suitable for storing patient data, calibration constants, and event logs in portable medical equipment where data integrity and low power are crucial.
Automotive Data Recorders
Applicable in automotive systems for black box recording, event data recording, and diagnostic trouble code storage due to its robustness and fast write capabilities.
Security Systems
Employed in access control systems and alarm panels for storing user credentials, event histories, and system configurations with reliable non-volatility.
