MB85RS128TYPNF-G-BCERE1

Memory IC Overview

The MB85RS128TYPNF-G-BCERE1 is a 128 Kbit Ferroelectric Random Access Memory (FeRAM) IC manufactured by RAMXEED. It features a 16K x 8 bit organization and utilizes a Serial Peripheral Interface (SPI) with a maximum operating frequency of 33 MHz. The device operates within a supply voltage range of 1.8 V to 3.6 V and supports an ambient temperature range from -40°C to +125°C. It is housed in an 8-pin plastic SOP package and is supplied in embossed carrier tape packaging.

Memory IC Feature Summary

• Nonvolatile memory cells retain data without backup power, supporting 10^13 read/write operations per byte.
• Serial Peripheral Interface (SPI) compatible with Mode 0 and Mode 3, enabling high-speed data transfer up to 33 MHz.
• Includes hardware write protection mechanisms via WP pin and status register bits for secure data management.
• Features low power consumption modes including standby and sleep states to optimize energy usage.

Memory IC Applications

• Automotive electronics requiring high-temperature reliability
• Industrial control systems needing frequent data logging
• Smart metering devices requiring long-term data retention

Memory IC Procurement Notes

Verify the specific ordering suffix BCERE1 corresponds to the embossed carrier tape shipping form rather than tube packaging. Confirm that the moisture sensitivity level and reflow soldering profiles align with your assembly line capabilities. Ensure the 8-pin SOP footprint matches your PCB design constraints before finalizing procurement orders.

Memory IC Selection Notes

Select this component when nonvolatile storage with high endurance and fast write speeds is required. It serves as a direct replacement for SRAM or Flash in applications where battery backup is undesirable. Consider the 1.8V to 3.6V voltage range compatibility with your system's logic levels and the -40°C to +125°C temperature rating for environmental suitability.

Memory IC Part Context

This part belongs to the MB85RS128TY series of FeRAM products from RAMXEED, formerly Fujitsu Semiconductor Memory Solutions Limited. The series is designed for high-reliability applications demanding extensive write cycles and data retention. The MB85RS128TYPNF-G-BCERE1 variant specifically denotes the surface-mount package with tape-and-reel delivery format.

Memory IC Replacement Considerations

Direct substitutes include other 128 Kbit SPI FeRAM devices from manufacturers such as Cypress or Ramtron, provided they match the 8-SOP package and voltage specifications. Verify interface timing and command set compatibility if replacing with different brand equivalents.
