MB85RC512TPNF-G-AME2

Memory IC Overview

The MB85RC512TPNF-G-AME2 is a 512Kbit (64 K × 8) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes a two-wire I2C serial interface and operates within a supply voltage range of 1.7 V to 3.6 V. The device supports clock frequencies up to 3.4 MHz in High Speed Mode and features an 8-pin plastic SOP package with a 150mil footprint. It offers high write endurance of at least 10^13 cycles per byte and data retention of 10 years at +85°C.

Memory IC Feature Summary

• Nonvolatile memory architecture eliminates the need for backup batteries while providing read/write endurance significantly exceeding other nonvolatile products.
• I2C serial interface allows connection of up to eight devices on the same bus using hardware-configurable address pins A0, A1, and A2.
• High-speed write operations remove the requirement for acknowledge polling sequences typically needed in Flash or EEPROM technologies.
• Hardware write protection via the WP pin disables writing operations when set to a high level, while maintaining read access.

Memory IC Applications

• Data logging systems requiring frequent write cycles without battery dependency
• Industrial control units needing reliable nonvolatile storage in harsh temperature environments
• Smart metering applications utilizing low-power standby and sleep modes
• Embedded systems integrating multiple slave devices via standard I2C communication

Memory IC Procurement Notes

Verify the specific ordering suffix AME2 corresponds to tray packaging before procurement. Confirm that the component meets RoHS compliance requirements for your region. Ensure the design accounts for the 8-pin SOP physical dimensions and lead pitch during PCB layout. Check for any product change notifications regarding mold resin or assembly sources prior to finalizing orders.

Memory IC Selection Notes

Select this component when a nonvolatile memory solution requires high endurance and fast write speeds without polling overhead. The I2C interface simplifies wiring compared to parallel memories. Consider the 1.7 V minimum operating voltage for compatibility with low-voltage logic levels. Evaluate the trade-off between the 512Kbit capacity and the limited pin count for address expansion needs.

Memory IC Part Context

This part belongs to the MB85RC512T series of FeRAM devices from RAMXEED, formerly Fujitsu Semiconductor Memory Solutions Limited. The series maintains original Fujitsu part numbering conventions. The MB85RC512T family includes variants with different packaging options such as tubes and embossed carrier tapes, all sharing the same core memory array and I2C functionality.

Memory IC Replacement Considerations

Direct substitutes include MB85RC512TPNF-G-JNE1 (tube), MB85RC512TPNF-G-JNERE1 (reel), and MB85RC512TPNF-G-AMERE2 (reel). These alternatives share identical electrical characteristics and pinouts but differ in shipping form factors. Verify packaging requirements when switching between these suffixes.
