MB85RS2MTAPNF-G-BDE1

Memory IC Overview

The MB85RS2MTAPNF-G-BDE1 is a 2 Mbit (262,144 words x 8 bits) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes the Serial Peripheral Interface (SPI) for communication and supports SPI modes 0 and 3 with a maximum operating frequency of 40 MHz. The device operates within a supply voltage range of 1.7 V to 3.6 V and functions in an ambient temperature range of -40 °C to +85 °C. It is housed in an 8-pin plastic SOP package with a 150mil footprint.

Memory IC Feature Summary

• Provides high endurance with 10^13 read/write operations per byte.
• Ensures data retention for up to 95 years at +55 °C or 10 years at +85 °C without backup power.
• Supports low-power operation with standby current of 50 µA and sleep mode functionality.
• Includes hardware write protection via WP pin and status register controls.

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage in embedded controllers
• Non-volatile memory for battery-powered devices
• Automotive information recording

Memory IC Procurement Notes

Verify the specific ordering suffix BDE1 corresponds to the tube shipping form when sourcing. Confirm that the required operating voltage and temperature ranges align with the system design specifications. Ensure the PCB layout accommodates the 8-pin SOP 150mil package dimensions. Check for any recent Product Change Notifications regarding manufacturing updates.

Memory IC Selection Notes

Select this component when high write endurance and fast access times are critical compared to Flash or EEPROM alternatives. Consider the SPI interface compatibility with the host microcontroller. Evaluate the power consumption requirements against the specified standby and sleep currents. Ensure the application environment stays within the -40 °C to +85 °C operational temperature limits.

Memory IC Part Context

This part belongs to the MB85RS2MTA series of FeRAM devices from RAMXEED, formerly Fujitsu Semiconductor. The series is designed for applications requiring frequent data writes and long-term data retention. RAMXEED continues to support existing product lines under its new brand identity while maintaining original part numbering conventions.

Memory IC Replacement Considerations

Direct substitutes include other parts within the MB85RS2MTA family with different packaging options, such as MB85RS2MTAPNF-G-BDERE1 for tape-and-reel delivery. Cross-vendor replacements require verification of SPI command set compatibility and electrical characteristics.
