MB85RS4MTPF-G-JNERE2

Memory IC Overview

The MB85RS4MTPF-G-JNERE2 is a 4 Mbit Ferroelectric Random Access Memory (FRAM) integrated circuit manufactured by RAMXEED. It features a Serial Peripheral Interface (SPI) for data communication and is organized as 512 k x 8 bits. The device operates within a supply voltage range of 1.8 V to 3.6 V and supports maximum clock frequencies of 33 MHz or 40 MHz depending on the specific operational mode. It is housed in an 8-pin Small Outline Package (SOP-8) with a width of 5.30 mm. The component is designed for surface mount technology and functions reliably across an extended industrial temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Non-volatile ferroelectric memory technology providing high read/write endurance without requiring power for data retention.
• Serial Peripheral Interface (SPI) compatibility enabling straightforward integration into standard digital systems.
• Extended operating temperature capability suitable for demanding industrial and automotive environments.

Memory IC Applications

• Industrial control systems requiring frequent data logging
• Automotive electronics needing reliable non-volatile storage
• Smart metering devices with high endurance requirements

Memory IC Procurement Notes

Verify the exact suffix against the manufacturer's latest documentation to confirm pinout and electrical specifications, as suffixes often denote package type or tape/reel variations. Ensure the selected variant matches the required clock speed and voltage parameters for the target application. Cross-reference the part number with official distributor catalogs to confirm current availability status and lead times before finalizing procurement plans.

Memory IC Selection Notes

Select this component when high-density non-volatile storage is required alongside rapid write speeds and extreme durability. The SPI interface simplifies PCB layout compared to parallel interfaces. Consider the wide voltage range and temperature tolerance if the operating environment involves significant thermal fluctuations or variable power supplies. Verify that the SOP-8 package dimensions fit the available board space constraints.

Memory IC Part Context

This part belongs to the MB85RS series of FRAM devices from RAMXEED, which are designed to replace traditional EEPROMs and Flash memories in applications where write endurance and speed are critical. The series offers various capacities and interface options, with this specific model focusing on higher density storage via the SPI protocol.
