MB85RS64VPNF-G-JNE1

Memory IC Overview

The MB85RS64VPNF-G-JNE1 is a 64 Kbit (8 K x 8) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes a Serial Peripheral Interface (SPI) for communication, supporting standard SPI modes 0 and 3 with a maximum operating frequency of 20 MHz. The device operates within a supply voltage range of 3.0 V to 5.5 V and functions across an ambient temperature range of -40 °C to +85 °C. It is housed in an 8-pin plastic SOP package.

Memory IC Feature Summary

• Non-volatile memory architecture utilizing ferroelectric process technology that retains data without backup power.
• High endurance capability allowing up to 10^12 read/write operations per byte.
• Supports serial communication via SPI interface compatible with mode 0 and mode 3 protocols.
• Includes hardware write protection mechanisms controlled by the WP pin and status register settings.

Memory IC Applications

• Data logging systems requiring high endurance and fast write speeds
• Industrial control applications needing reliable non-volatile storage
• Embedded systems interfacing with microcontrollers via SPI

Memory IC Procurement Notes

Verify the specific ordering suffix JNE1 corresponds to the tube packaging format required for your assembly line. Confirm that the 3.0 V minimum supply voltage aligns with your system's power rails. Ensure ESD handling procedures are followed as the component is sensitive to electrostatic discharge.

Memory IC Selection Notes

Select this component when a non-volatile memory solution with significantly higher write endurance than Flash or EEPROM is required. It is suitable for applications where frequent data updates occur without the wait times associated with flash programming cycles. Verify compatibility with the host microcontroller's SPI clock speed and voltage levels.

Memory IC Part Context

This part belongs to the MB85RS64V family of FeRAM devices from RAMXEED, formerly Fujitsu Semiconductor Memory Solutions Limited. The family offers various packaging options including tubes and embossed carrier tapes. The device is designed to replace traditional SRAM solutions that require battery backup while offering superior durability compared to conventional non-volatile memories.

Memory IC FAQ

What SPI modes does the MB85RS64VPNF-G-JNE1 support?

The device supports SPI mode 0 (CPOL=0, CPHA=0) and SPI mode 3 (CPOL=1, CPHA=1).

How is the chip select function managed internally?

The Chip Select (CS) pin is pulled up internally to the VDD pin. When CS is high, the device enters deselect status and outputs become High-Z.

What is the data retention period at elevated temperatures?

Data retention is specified as 10 years at +85 °C, 95 years at +55 °C, and over 200 years at +35 °C.
