MB85RC04VPNF-G-JNERE1

Memory IC Overview

The MB85RC04VPNF-G-JNERE1 is a 4 Kbit (512 words x 8 bits) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes a two-wire I2C serial interface for communication, supporting maximum operating frequencies up to 1 MHz. The device operates within a power 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 with a 150mil body width.

Memory IC Feature Summary

• Nonvolatile memory cells retain data without requiring a backup battery.
• Read/write endurance reaches at least 10^12 cycles per byte.
• No polling sequence is required after writing operations.
• Hardware write protection is available via the WP pin.

Memory IC Applications

• Data logging systems
• Industrial control equipment
• Instrumentation devices

Memory IC Procurement Notes

Verify the specific ordering suffix JNERE1 to confirm the embossed carrier tape shipping form. Ensure the design accommodates the 8-pin SOP physical dimensions and electrical requirements. Confirm moisture sensitivity level handling procedures are followed during assembly.

Memory IC Selection Notes

Select this component when high endurance and fast write speeds are required compared to Flash or EEPROM alternatives. The I2C interface simplifies connection to microcontrollers. Verify that the 3.0 V to 5.5 V supply range matches the system voltage rails.

Memory IC Part Context

This part belongs to the MB85RC04V series of FeRAM chips from RAMXEED, formerly Fujitsu Semiconductor Memory Solutions Limited. The manufacturer continues to support existing products while maintaining original part numbering conventions.
