MB85RC16PNF-G-JNE1

Memory IC Overview

The MB85RC16PNF-G-JNE1 is a 16 Kbit (2,048 words x 8 bits) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes a two-wire serial interface (I2C) and operates within an ambient temperature range of -40°C to +85°C. The device functions with a supply voltage between 2.7 V and 3.6 V. Key electrical specifications include a maximum operating frequency of 1 MHz, read/write endurance of at least 10^12 cycles per byte, and standby current typically at 0.1 µA. Data retention is guaranteed for 10 years at +85°C. The component is housed in an 8-pin plastic SOP package.

Memory IC Feature Summary

• Non-volatile memory architecture that retains data without requiring a backup battery.
• High write endurance capability supporting up to 10^12 read/write operations per byte.
• Direct byte-level writing functionality eliminating the need for programming wait times or busy state polling sequences.
• Hardware-based write protection via the WP pin to secure the entire memory array.

Memory IC Applications

• Industrial systems requiring frequent data logging and high durability.
• Automotive electronics demanding reliable non-volatile storage under varying temperatures.
• Smart metering devices needing low power consumption and long data retention.
• Embedded controllers utilizing I2C bus communication for configuration storage.

Memory IC Procurement Notes

Verify the specific ordering suffix to confirm the package type and shipping format. The JNE1 suffix indicates an 8-pin plastic SOP tube. Confirm moisture sensitivity level requirements and reflow soldering profiles prior to assembly. Ensure the design supports the required pull-up resistors for the SDA and SCL lines. Check for any recent product change notifications regarding material composition or manufacturing site updates.

Memory IC Selection Notes

Select this component when a system requires high rewrite endurance and immediate write completion without waiting for internal programming cycles. It is suitable for applications where battery backup for SRAM is undesirable due to maintenance or environmental constraints. Ensure the host microcontroller supports the I2C protocol and can handle the open-drain output characteristics of the SDA line. Verify that the available supply voltage range aligns with the 2.7 V to 3.6 V operational limits.
