MB85RC64TAPN-G-AMEWE1
Overview
The MB85RC64TAPN-G-AMEWE1 is a 64Kbit non-volatile Ferroelectric Random Access Memory (FRAM) chip organized as 8K x 8 bits. It utilizes an I2C interface capable of high-speed 3.4 MHz operation while maintaining extremely low power consumption across a 1.8V to 3.6V supply range. Unlike standard EEPROM, this FRAM technology offers virtually unlimited read/write endurance and high-speed data writes without a write-cycle delay.
Why Choose This Part
This device offers superior endurance of 10 trillion read/write cycles, significantly outperforming EEPROM and Flash for logging applications. The fast I2C bus speed of 3.4 MHz allows for rapid data transfer, while the compact 8-SON package (2x3mm) minimizes PCB footprint in space-constrained wearable designs.
Applications
Key Specifications
Getting Started
Integrate this device into your design by connecting the I2C SDA and SCL lines with appropriate pull-up resistors to a microcontroller operating within the 1.8V to 3.6V range. Since FRAM does not require a polling delay after a write command, you can immediately initiate the next bus transaction to maximize throughput. Use standard I2C libraries while ensuring your bus controller supports High-Speed mode if 3.4 MHz operation is required.
