MB85RC64VPNF-G-JNE1

Memory IC Overview

The MB85RC64VPNF-G-JNE1 is a 64 Kbit (8 K × 8 bit) Ferroelectric Random Access Memory (FeRAM) utilizing the I2C serial interface. It operates within a supply voltage range of 3.0 V to 5.5 V and supports clock frequencies up to 1 MHz. The device features an operating temperature range from -40°C to +85°C, with typical standby current of 5 µA and operating current of 90 µA at 1 MHz. It offers write endurance of 10^12 cycles per byte and data retention exceeding 200 years at +35°C.

Memory IC Feature Summary

• Nonvolatile memory retains data without backup batteries using ferroelectric process technology.
• I2C two-wire serial interface allows connection of up to eight devices on the same bus.
• High-speed write operations eliminate the need for acknowledge polling sequences after writing.
• Hardware write protection via the WP pin disables writing while maintaining read access.

Memory IC Applications

• Data logging in industrial systems requiring high endurance
• Configuration storage in embedded controllers
• Smart metering applications needing long-term data retention

Memory IC Procurement Notes

Verify the specific ordering suffix JNE1 corresponds to the tube packaging format required for your assembly line. Confirm that the 8-pin plastic SOP 150mil package dimensions align with your PCB footprint design. Ensure the I2C address configuration pins are correctly tied to logic levels to match your system's master controller requirements.

Memory IC Selection Notes

Select this component when a nonvolatile memory solution requires high write endurance and fast write speeds without polling delays. It is suitable for designs operating between 3.0 V and 5.5 V that utilize standard I2C communication protocols. Consider the 8-pin SOP package constraints and the requirement for external pull-up resistors on the SDA and SCL lines.

Memory IC Part Context

This part belongs to the MB85RC64V series of FeRAM devices manufactured by RAMXEED. It serves as a drop-in replacement for traditional EEPROMs in many applications due to its faster write times and higher endurance. The series maintains compatibility with standard I2C bus protocols while offering superior reliability characteristics.

Memory IC FAQ

Does the MB85RC64VPNF-G-JNE1 require an acknowledge polling sequence after writing?

No, the device performs high-speed write operations, so no waiting time for ACK polling occurs after issuing the Stop Condition.

What is the default state of the Write Protect (WP) pin if left unconnected?

The WP pin is internally pulled down to VSS, which is recognized as the 'L' level, meaning the device is write-enabled by default.
