MB85RS64PNF-G-JNE1

Memory IC Overview

The MB85RS64PNF-G-JNE1 is a 64 Kbit (8,192 words x 8 bits) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes the Serial Peripheral Interface (SPI) for communication and operates within a supply voltage range of 2.7 V to 3.6 V. The device supports a maximum clock frequency of 20 MHz and functions across an ambient temperature range of -40°C to +85°C. It is housed in an 8-pin plastic Small Outline Package (SOP).

Memory IC Feature Summary

• Non-volatile memory architecture utilizing ferroelectric process technology that retains data without backup power.
• High endurance capability supporting up to 10^12 read/write operations per byte.
• Supports SPI Mode 0 and Mode 3 with automatic address increment during sequential access.
• Includes hardware write protection features controlled via status register bits and dedicated pins.

Memory IC Applications

• Data logging systems requiring high endurance and fast write speeds.
• Industrial control applications operating in extended temperature environments.
• Embedded systems needing non-volatile storage for configuration parameters.
• Automotive electronics compliant with AEC-Q100 standards.

Memory IC Procurement Notes

Verify the specific ordering suffix JNE1 corresponds to the tube packaging format required for your assembly line. Confirm that the 2.7 V to 3.6 V operating voltage aligns with your system's power rails. Ensure design compatibility with the 8-pin SOP footprint and check moisture sensitivity level requirements before soldering.

Memory IC Selection Notes

Select this component when a non-volatile memory solution offers superior write endurance compared to Flash or EEPROM technologies. It is suitable for applications demanding low standby current and immediate write completion without erase cycles. Consider the SPI interface constraints and voltage levels relative to the host microcontroller capabilities.
