MB85RC1MTPNF-G-AME2

Memory IC Overview

The MB85RC1MTPNF-G-AME2 is a 1 Mbit (131,072 words x 8 bits) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes an I2C two-wire serial interface and operates within a supply voltage range of 1.8 V to 3.6 V. The device supports clock frequencies up to 3.4 MHz in High Speed Mode. It features a read/write endurance of at least 10^13 cycles per byte and data retention exceeding 10 years at +85°C. The component is housed in an 8-pin plastic SOP (150mil) package.

Memory IC Feature Summary

• Nonvolatile memory architecture that retains data without backup batteries
• High-speed write operations eliminating the need for polling sequences
• Configurable hardware write protection via dedicated pin
• Low-power operation with standby and sleep modes

Memory IC Applications

• Data logging systems requiring frequent write cycles
• Industrial control equipment needing high endurance memory
• Smart metering devices for usage data storage
• Medical instrumentation requiring reliable nonvolatile storage

Memory IC Procurement Notes

Verify the specific ordering suffix corresponds to the Tray packaging format required for this part number. Confirm the manufacturer designation as RAMXEED, noting the transition from Fujitsu Semiconductor. Ensure compatibility with I2C bus voltage levels between 1.8 V and 3.6 V during system integration.

Memory IC Selection Notes

Select this component when applications demand high write endurance beyond standard EEPROM or Flash capabilities. It is suitable for designs requiring immediate data persistence without programming wait times. Consider the 8-pin SOP package constraints and I2C address configuration options involving external pins A1 and A2 for multi-device bus setups.

Memory IC Part Context

This FeRAM belongs to the MB85RC series, designed for general-purpose nonvolatile memory applications. The technology replaces traditional battery-backed SRAM solutions by providing instant access and unlimited write endurance. RAMXEED continues the legacy of Fujitsu's ferroelectric memory technologies, maintaining identical part numbering conventions for existing product lines.

Memory IC Replacement Considerations

Direct substitutes include MB85RC1MTPNF-G-JNE1 (Tube), MB85RC1MTPNF-G-JNERE1 (Tape & Reel), and MB85RC1MTPNF-G-AMERE2 (Tape & Reel). These variants share identical electrical specifications but differ in shipping packaging formats.

Memory IC FAQ

Does the MB85RC1MT require an acknowledge polling sequence after writing?

No, the device performs high-speed write operations, so no waiting time for ACK polling occurs after issuing the Stop Condition.

How is the device address configured on the I2C bus?

The device address code is determined by the external logic levels applied to pins A1 and A2, allowing up to four devices to be connected to the same bus.

What is the function of the WP pin?

The Write Protect pin disables writing operations when set to a high level. When open or low, the entire memory array can be overwritten, though reading remains enabled regardless of the pin state.
