Memory IC datasheet and documents for MB85RC256LYPN-G-AMEWE1

MB85RC256LYPN-G-AMEWE1

Memory IC Overview

The MB85RC256LYPN-G-AMEWE1 is a 256 Kbit (32 K x 8) Ferroelectric Random Access Memory (FeRAM) utilizing an I2C serial interface. It operates within a supply voltage range of 1.7 V to 1.95 V and supports clock frequencies up to 3.4 MHz in High Speed Mode. The device features a write endurance of at least 10^13 cycles per byte and does not require polling sequences after writing. It is housed in an 8-pin plastic SOP package with a lead pitch of 1.27 mm.

Memory IC Feature Summary

Nonvolatile memory architecture retains data without backup batteries, eliminating the need for programming wait times or acknowledge polling sequences found in Flash or EEPROM technologies.
Supports bidirectional two-wire serial communication via SDA and SCL pins, allowing multiple slave devices to connect to a single master controller using unique hardware address codes.
Includes a dedicated Write Protect pin that disables write operations when held high while maintaining read access, with internal pull-down ensuring write-enabled status if left open.

Memory IC Applications

Data logging systems requiring high endurance and fast write speeds
Embedded controllers needing nonvolatile storage without battery backup
Industrial instrumentation operating under wide temperature conditions

Memory IC Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and shipping form. The AMEWE1 suffix indicates an embossed carrier tape configuration for surface mount assembly. Ensure compatibility with the required 1.7 V to 1.95 V supply voltage range during system design validation.

Memory IC Selection Notes

Select this component for applications demanding extreme write endurance and low power consumption. The I2C interface simplifies board layout by minimizing pin count. Consider the narrow voltage window of 1.7 V to 1.95 V when designing power rails, as operation outside these limits may affect reliability.

Memory IC Part Context

This part belongs to the MB85RC256LY family of FeRAM devices manufactured by RAMXEED. It represents a continuation of Fujitsu Semiconductor's memory solutions, maintaining original part numbering conventions. The technology leverages ferroelectric process and silicon gate CMOS processes for nonvolatile cell formation.

Memory IC Replacement Considerations

Direct substitutes are not explicitly listed in the provided datasheet. Verify functional equivalence regarding I2C protocol timing, voltage levels, and physical footprint before replacing with other 256 Kbit I2C FRAM parts.
