Memory IC datasheet and documents for MB85RS256TYPNF-G-BCE1

MB85RS256TYPNF-G-BCE1

Memory IC Overview

The MB85RS256TYPNF-G-BCE1 is a 256 Kbit (32 K x 8) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes the Serial Peripheral Interface (SPI) for communication and supports operating frequencies up to 33 MHz. The device operates within a supply voltage range of 1.8 V to 3.6 V and is designed for ambient temperatures between -40 °C and +125 °C. It is housed in an 8-pin plastic Small Outline Package (SOP).

Memory IC Feature Summary

High endurance capability supporting 10^13 read/write operations per byte.
Nonvolatile data retention without requiring backup batteries.
Supports SPI Mode 0 and Mode 3 with fast write cycle times.
Includes programmable block protection and write protect functions.

Memory IC Applications

Automotive applications requiring high-temperature operation.
Industrial systems needing reliable nonvolatile storage.
Embedded controllers utilizing SPI interfaces.

Memory IC Procurement Notes

Verify the specific ordering suffix BCE1 to confirm the assembly site and shipping form, as this variant corresponds to tube packaging. Ensure compatibility with the required voltage levels and temperature ranges for the target environment. Confirm RoHS compliance status through official documentation before integration.

Memory IC Selection Notes

Select this component when high endurance and fast write speeds are critical compared to Flash or EEPROM alternatives. It is suitable for designs requiring battery-free nonvolatile memory in harsh thermal environments. Verify that the system interface supports standard SPI protocols compatible with Mode 0 and Mode 3.

Memory IC Part Context

This part belongs to the MB85RS256TY series of FeRAM devices from RAMXEED, formerly Fujitsu Semiconductor Memory Solutions Limited. The series maintains original part numbering while transitioning manufacturing support. It is distinct from I2C-based variants in the same family due to its serial peripheral interface architecture.
