MB85RC16VPNF-G-JNN1ERE1

Memory IC Overview

The MB85RC16VPNF-G-JNN1ERE1 is a 16-kilobit Ferroelectric Random Access Memory (FRAM) integrated circuit manufactured by RAMXEED. It utilizes an I2C serial interface for data communication and supports a maximum clock frequency of 1 MHz. The device operates within a supply voltage range of 3 V to 5.5 V, ensuring compatibility with standard logic levels. It features a 2 K x 8 memory organization and is housed in an 8-SOP surface-mount package. The component is designed for industrial applications, functioning reliably across a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Non-volatile ferroelectric memory technology providing high endurance and low power consumption without requiring write wait times.
• I2C serial interface support enabling simple two-wire connectivity for efficient data transfer.
• Wide operating voltage range accommodating both 3V and 5V system requirements.

Memory IC Applications

• Industrial data logging systems requiring frequent write cycles
• Embedded controllers needing non-volatile parameter storage
• IoT devices with limited power budgets

Memory IC Procurement Notes

Verify the specific suffix JNN1ERE1 against the official RAMXEED datasheet to confirm tape-and-reel packaging and RoHS compliance status. Ensure the ordering code matches the exact voltage and interface specifications required for your design. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and lifecycle status before finalizing procurement plans.

Memory IC Selection Notes

Select this component when an I2C interface is preferred over SPI for board space or pin count constraints. The wide voltage range makes it suitable for mixed-voltage systems. Consider the 1 MHz speed limit for application timing requirements. Verify that the SOP-8 package fits the available footprint on the printed circuit board layout.

Memory IC Part Context

This part belongs to the MB85RC series of FRAM devices from RAMXEED, which are successors to Fujitsu's ferroelectric memory line. These chips replace traditional EEPROMs and Flash in applications demanding high rewrite endurance. The series offers non-volatility with byte-level access capabilities, distinguishing it from block-oriented flash memories.

Memory IC Replacement Considerations

Check for direct substitutes within the MB85RC family with different capacities or suffixes. Verify pin compatibility if replacing older MB85R variants. Ensure any alternative maintains the I2C protocol and voltage range specifications.
