Memory IC datasheet and documents for MB85RC256TYPNF-GS-BCERE1

MB85RC256TYPNF-GS-BCERE1

Memory IC Overview

The MB85RC256TYPNF-GS-BCERE1 is a 256 Kbit (32 K x 8) Ferroelectric Random Access Memory (FeRAM) featuring an I2C serial interface. It operates within a supply voltage range of 1.8 V to 3.6 V and supports clock frequencies up to 3.4 MHz in High Speed Mode. The device provides read/write endurance of at least 10^13 cycles per byte and data retention exceeding 70 years at +85°C. It is housed in an 8-pin plastic SOP package with a lead pitch of 1.27 mm, designed for surface mount technology.

Memory IC Feature Summary

Nonvolatile memory architecture eliminates the need for backup batteries while retaining data without power.
High-speed write operations remove the requirement for polling sequences typically found in Flash or EEPROM technologies.
Integrated hardware write protection allows entire memory array locking via the WP pin.
Supports multiple slave devices on a single bus through configurable address pins A0, A1, and A2.

Memory IC Applications

Automotive systems requiring AEC-Q100 compliance
Industrial control units needing high endurance logging
Smart metering infrastructure for reliable data storage

Memory IC Procurement Notes

Verify that the ordering suffix matches the required packaging format, as this specific part number indicates embossed carrier tape delivery. Confirm the manufacturer designation aligns with current RAMXEED Limited branding rather than legacy Fujitsu Semiconductor labels. Ensure design-in documentation references the correct datasheet version DS501-00077-1v1-E for accurate electrical specifications.

Memory IC Selection Notes

Select this component when a nonvolatile memory solution requires significantly higher write endurance than standard EEPROM or Flash alternatives. The I2C interface simplifies PCB routing compared to SPI variants, while the wide operating temperature range ensures reliability in harsh environments. Consider the 1.8 V to 3.6 V supply range compatibility with existing system power rails before finalizing the design.

Memory IC Part Context

This FeRAM belongs to the MB85RC256TY series, manufactured by RAMXEED Limited following the corporate name change from Fujitsu Semiconductor Memory Solutions Limited. The product maintains original part numbering conventions while updating manufacturer identification. It represents a specialized memory class distinct from volatile SRAM or traditional nonvolatile flash technologies.
