MB85RS64PNF-G-JNE1

Overview

The MB85RS64PNF-G-JNE1 is a 64-kbit non-volatile Ferroelectric Random Access Memory (FRAM) chip utilizing a serial SPI interface. Unlike standard EEPROM or Flash, FRAM offers virtually unlimited write endurance and high-speed write cycles without the need for a polling sequence. This device operates within a voltage range of 2.7V to 3.6V and supports clock frequencies up to 20MHz.

Why Choose This Part

This FRAM provides 10 to the 12th power read/write cycles, significantly outperforming traditional non-volatile memory technologies. It features low power consumption with a 1.5mA typical operating current at 20MHz and a fast write speed that eliminates the write-delay time required by EEPROM.

Applications

Getting Started

To integrate this memory, connect the SPI lines (SCK, SI, SO) and the Chip Select (CS) pin to your microcontroller. Ensure the VDD remains between 2.7V and 3.6V, and use standard SPI Mode 0 or Mode 3 for communication. Developers can treat writes similarly to SRAM due to the lack of a page-write delay.
