MB85RC128APNF-G-JNERE1

Memory IC Overview

The MB85RC128APNF-G-JNERE1 is a 128 Kbit (16,384 words x 8 bits) 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 a write endurance of at least 10^12 cycles per byte and data retention exceeding 10 years at +85°C. The component is housed in an 8-pin plastic SOP package.

Memory IC Feature Summary

• Nonvolatile memory retains data without backup power, eliminating the need for polling sequences after writing operations.

Memory IC Applications

• I2C bus slave devices requiring nonvolatile storage
• Systems needing high-speed write operations without programming wait times

Memory IC Procurement Notes

Verify the specific ordering suffix JNERE1 corresponds to the embossed carrier tape shipping form with a minimum quantity of 1500 units. Confirm that the RoHS compliance status matches current regulatory requirements for your region. Ensure the moisture sensitivity level 3 handling procedures are followed during assembly to prevent damage.

Memory IC Selection Notes

Select this component when a nonvolatile memory solution requires fast write speeds without the latency associated with Flash or EEPROM technologies. The I2C interface simplifies connectivity for master-slave configurations. Consider the 10^12 cycle endurance for applications involving frequent data updates where long-term reliability is critical.

Memory IC FAQ

Does the MB85RC128A require acknowledge polling after a write operation?

No, the device performs write operations at the same speed as read operations, so no waiting time for ACK polling occurs.

What is the function of the WP pin?

The Write Protect pin disables writing operations when set to the 'H' level, while reading remains enabled regardless of the pin state.
