MB85RC256TYPNF-G-BCERE1

Memory IC Overview

The MB85RC256TYPNF-G-BCERE1 is a 256 Kbit (32 K x 8) Ferroelectric Random Access Memory (FeRAM) utilizing 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, with standard support for Fast Mode Plus at 1 MHz. The device features a read/write endurance of at least 10^13 cycles per byte and data retention exceeding 70 years at +85°C. It functions across an ambient temperature range of -40°C to +125°C and is housed in an 8-pin plastic SOP package.

Memory IC Feature Summary

• Non-volatile memory architecture eliminates the need for backup batteries while retaining data without power.
• High-speed write operations remove the requirement for polling sequences or programming wait times after writing.
• Integrated hardware write protection allows disabling write operations via the WP pin while maintaining read access.
• Low-power consumption includes standby and sleep modes to minimize energy usage during idle periods.

Memory IC Applications

• Industrial systems requiring frequent data logging and high rewrite endurance
• Automotive applications demanding wide operating temperature ranges and reliability
• Embedded devices utilizing I2C bus communication for configuration storage

Memory IC Procurement Notes

Verify the specific ordering suffix to confirm the packaging format. The BCERE1 suffix indicates the component is supplied in embossed carrier tape suitable for automated surface-mount assembly. Confirm that the required quantity aligns with the manufacturer's minimum shipping specifications for this tape-and-reel configuration before finalizing orders.

Memory IC Selection Notes

Select this component when an I2C interface is required alongside high endurance and wide temperature operation. Ensure the system voltage falls within the 1.8 V to 3.6 V range. Consider the 8-pin SOP package dimensions for PCB layout constraints. Verify if High Speed Mode compatibility is necessary for the master controller to utilize the 3.4 MHz capability.

Memory IC Part Context

This part belongs to the MB85RC256TY series of FeRAM devices manufactured by RAMXEED. The series maintains the legacy specifications of Fujitsu Semiconductor products. The TYPNF-G-BCERE1 designation specifically identifies the 8-pin SOP variant packaged in tape and reel format, distinguishing it from tube or DFN package options within the same memory density family.

Memory IC Replacement Considerations

Direct substitutes include other MB85RC256TY variants such as MB85RC256TYPNF-G-BCE1 for tube packaging or MB85RC256TYPN-G-AWE1 for DFN packaging. Cross-manufacturer replacements require verification of I2C timing parameters and voltage levels to ensure functional compatibility.
