MB85RS256BPNF-G-JNE1

Memory IC Overview

The MB85RS256BPNF-G-JNE1 is a 256 Kbit (32 K x 8) Ferroelectric Random Access Memory (FeRAM) utilizing SPI. It operates within a voltage range of 2.7 V to 3.6 V and supports clock frequencies up to 33 MHz for most commands, with READ operations limited to 25 MHz. The device features high endurance of 10^12 read/write cycles per byte and data retention exceeding 10 years at +85°C. It functions in an ambient temperature range of -40°C to +85°C and is housed in an 8-pin plastic SOP package.

Memory IC Feature Summary

Non-volatile memory architecture using ferroelectric process technology eliminates the need for backup batteries.
Serial Peripheral Interface (SPI) support for Mode 0 and Mode 3 communication protocols.
High write endurance capability significantly surpassing traditional Flash and E2PROM technologies.
Integrated status register with configurable block protection and write-protect mechanisms.

Memory IC Applications

Data logging systems requiring frequent write operations
Industrial control applications demanding high reliability
Embedded systems needing battery-free volatile-like memory performance

Memory IC Procurement Notes
