MB85RS2MTAPNF-G-BDERE1

Memory IC Overview

The MB85RS2MTAPNF-G-BDERE1 is a 2 Mbit (262,144 words x 8 bits) 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 40 MHz. The device operates within a supply voltage range of 1.7 V to 3.6 V and functions reliably in ambient temperatures from -40 °C to +85 °C. It is housed in an 8-pin plastic SOP package with a lead pitch of 1.27 mm.

Memory IC Feature Summary

• Nonvolatile memory architecture utilizing ferroelectric process technology that retains data without backup power.
• High endurance capability supporting 10^13 read/write operations per byte, exceeding Flash and E2PROM limits.
• Supports SPI Mode 0 and Mode 3 with fast write speeds and no wait time required for data programming.
• Includes hardware write protection features via WP pin and status register block protect settings.

Memory IC Applications

• Data logging systems requiring frequent updates and high endurance.
• Industrial control applications needing reliable nonvolatile storage in varying temperatures.
• Embedded systems replacing SRAM or Flash where low power consumption and fast write cycles are critical.

Memory IC Procurement Notes

Verify the specific ordering suffix BDERE1 corresponds to the 8-pin plastic SOP (150mil) package with embossed carrier tape shipping form. Confirm the manufacturer designation as RAMXEED Limited, which succeeded Fujitsu Semiconductor Memory Solutions Limited. Ensure compatibility with standard SPI interfaces on the host microcontroller before procurement.

Memory IC Selection Notes

Select this component when a 2 Mbit capacity is required alongside high-speed serial access. The 40 MHz maximum clock frequency makes it suitable for bandwidth-sensitive applications. Consider the 1.7 V minimum supply voltage for low-power designs. Verify that the 8-pin SOP footprint fits the PCB layout constraints compared to other package options like the 208mil variant.

Memory IC Part Context

This part belongs to the MB85RS2MTA family of FeRAM devices. RAMXEED Limited continues to offer and support these products while maintaining the original Fujitsu part numbering system. The device represents a transition from traditional Flash memory technologies by offering superior write endurance and faster write times without the need for complex erase cycles.
