MB85RC64VPNF-G-JNERE1

Memory IC Overview

The MB85RC64VPNF-G-JNERE1 is a 64 Kbit (8 K × 8 bit) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes a two-wire I2C serial interface for communication, supporting standard mode up to 100 kHz, fast mode up to 400 kHz, and fast mode plus up to 1 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 features high write endurance of at least 10^12 cycles per byte and data retention exceeding 200 years at +35°C. The component is housed in an 8-pin plastic SOP package with a 150mil width.

Memory IC Feature Summary

• Nonvolatile memory cells retain data without backup batteries, eliminating the need for polling sequences after writing operations.

Memory IC Applications

• Data logging systems requiring frequent write cycles
• Industrial control applications needing high endurance memory
• Embedded systems utilizing I2C bus communication

Memory IC Procurement Notes
