MB85RS1MTPW-G-APEWE1

Memory IC Overview

The MB85RS1MTPW-G-APEWE1 is a 1 Mbit (131,072 words x 8 bits) Ferroelectric Random Access Memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes a Serial Peripheral Interface (SPI) for communication and operates within a supply voltage range of 1.7 V to 3.6 V. The device supports clock frequencies up to 25 MHz at lower voltages, 30 MHz generally, and 40 MHz using the Fast Read command at higher voltages. It features high endurance of 10^13 read/write operations per byte and data retention of 10 years at +85°C or 95 years at +55°C. The component is housed in an 8-pin plastic Wafer Level Package (WLP-8P-M01) with dimensions of 2.28 mm x 3.09 mm.

Memory IC Feature Summary

• Non-volatile memory architecture utilizing ferroelectric process technology that retains data without backup power.
