MB85RC04VPNF-G-AMERE2

Memory IC Overview

The MB85RC04VPNF-G-AMERE2 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, operating with a maximum clock frequency of 1 MHz. The device functions within an operating power supply voltage range of 3.0 V to 5.5 V and supports an ambient temperature range from -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 architecture retains data without requiring a backup battery.
• High write endurance capability reaching at least 10^12 cycles per byte.
• Eliminates the need for polling sequences after write operations.
• Includes hardware write protection via the WP pin.

Memory IC Applications

• Embedded systems requiring nonvolatile storage without battery maintenance
• Industrial control applications demanding high write endurance
• I2C bus networks utilizing multiple slave devices

Memory IC Procurement Notes

Verify the specific ordering suffix AMERE2 corresponds to the embossed carrier tape shipping form containing 1500 units per reel. Confirm that the component meets RoHS compliance standards and observe Moisture Sensitivity Level 3 requirements during handling and reflow soldering processes to ensure proper device integrity.

Memory IC Selection Notes

Select this component when a small capacity nonvolatile memory solution is required alongside standard I2C interfaces. It serves as a suitable alternative to Flash or EEPROM where frequent write cycles are necessary, eliminating programming wait times. Ensure the system voltage aligns with the 3.0 V to 5.5 V operational range and that the SOP-8 footprint fits the design constraints.
