MB85RC256VPF-G-JNERE2

Memory IC Overview

The MB85RC256VPF-G-JNERE2 is a 256 kbit Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It features an I2C serial interface and operates within a supply voltage range of 2.7 V to 5.5 V. The memory organization is specified as 32 K x 8 bits, supporting a maximum clock frequency of 1 MHz. Designed for surface-mount applications, the component is housed in an SOP-8 package with a 208mil footprint. It functions reliably across an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Non-volatile data retention capability inherent to ferroelectric technology
• Serial communication via standard I2C protocol for simplified system integration
• High endurance suitable for frequent write operations

Memory IC Applications

• Industrial metering systems requiring reliable data logging
• Automotive information recording modules
• Robotics control units needing persistent state storage

Memory IC Procurement Notes

Verify the specific suffix JNERE2 against official RAMXEED documentation to confirm tape-and-reel packaging and lead-free compliance. Ensure the design supports the 2.7V to 5.5V operating range and I2C electrical characteristics. Confirm humidity sensitivity handling requirements during assembly. Cross-reference the SOP-8 pinout with the latest datasheet to prevent layout errors.

Memory IC Selection Notes

Select this component when a non-volatile memory solution requires high write endurance and low power consumption without the complexity of flash management. The I2C interface minimizes pin count compared to parallel alternatives. Verify that the 256 kbit capacity meets system storage needs and that the SOP-8 package fits the available PCB real estate constraints.

Memory IC Part Context

This part belongs to the MB85RC series of FeRAM devices from RAMXEED, formerly Fujitsu Semiconductor. The series utilizes ferroelectric material to provide fast read/write speeds and high durability. The VP designation typically indicates voltage compatibility, while the PF suffix denotes the SOP-8 package type. This family serves as a robust alternative to traditional EEPROM and Flash technologies in data-intensive applications.
