MB85RC16PN-G-AMERE1

Memory IC Overview

The MB85RC16PN-G-AMERE1 is a 16 Kbit (2K x 8) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes an I2C two-wire serial interface with a maximum operating frequency of 1 MHz. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports an ambient temperature range from -40°C to +85°C. It features high endurance of at least 10^12 read/write cycles per byte and data retention exceeding 10 years at 85°C. The component is housed in an 8-pin plastic SON package.

Memory IC Feature Summary

• Non-volatile memory retains data without backup batteries, offering significantly higher write endurance compared to Flash or EEPROM technologies.
• Supports byte-level writing operations without requiring programming wait times or busy state polling sequences.
• Includes a hardware Write Protect (WP) pin that disables write operations when held high while allowing continuous reading.
• Operates as an I2C slave device compatible with standard multi-master party-line bus configurations.

Memory IC Applications

• Data logging systems requiring frequent updates with high endurance
• Industrial control units needing reliable non-volatile storage in varying temperatures
• Smart metering devices for secure parameter storage

Memory IC Procurement Notes

Verify the specific ordering suffix AMERE1 corresponds to the 8-pin plastic SON package and embossed carrier tape shipping form. Confirm RoHS compliance status and REACH registration details against current manufacturer documentation. Ensure design-in compatibility with I2C pull-up resistor requirements and voltage levels before finalizing procurement orders.

Memory IC Selection Notes

Select this component for applications demanding high-speed byte writes without erase cycles. Compare against EEPROM alternatives where write endurance exceeds typical limits. Verify I2C bus speed requirements do not exceed 1 MHz. Consider the 8-pin SON footprint constraints versus SOP options if board space is limited.

Memory IC Part Context

This part belongs to the MB85RC16 series of FeRAM devices produced by RAMXEED, formerly Fujitsu Semiconductor. The series provides non-volatile memory solutions using ferroelectric process technology. The MB85RC16 specifically targets low-power, high-endurance memory needs in compact surface-mount packages.

Memory IC FAQ

Does the MB85RC16 require acknowledge polling after write operations?

No, the device performs high-speed write operations internally, eliminating the need for ACK polling waiting times typically required by EEPROMs.

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

The WP pin is internally pulled down to VSS, so an open state is recognized as logic Low, enabling write operations.
