MB85RS1MTPN-G-AWEWE1

Memory IC Overview

The RAMXEED MB85RS1MTPN-G-AWEWE1 is a 1 Mbit (128 K x 8) Ferroelectric Random Access Memory (FeRAM) utilizing SPI serial interface technology. It operates within a voltage range of 1.8 V to 3.6 V and supports clock frequencies up to 25 MHz at lower voltages, 30 MHz at higher voltages, and 40 MHz for fast read commands. The device features high endurance of 10^13 write cycles and data retention exceeding 10 years at +85°C. It is housed in an 8-pin plastic DFN package measuring 5 mm by 6 mm.

Memory IC Feature Summary

• Non-volatile memory architecture eliminates the need for backup batteries while providing rapid write speeds without wait times.
• Serial Peripheral Interface (SPI) compatibility with support for Mode 0 and Mode 3 operation modes.
• Integrated block protection and write protect mechanisms controlled via status register bits.

Memory IC Applications

• Data logging systems requiring frequent write operations
• Industrial control applications needing high endurance memory
• Embedded systems with limited power supply constraints

Memory IC Procurement Notes

Verify the specific ordering suffix AWEWE1 to confirm the 8-pin DFN package type and embossed carrier tape shipping form. Ensure design compatibility with the specified operating temperature range and voltage levels before integration. Confirm moisture sensitivity handling requirements during assembly.

Memory IC Selection Notes

Select this component when high write endurance and low power consumption are critical compared to Flash or EEPROM alternatives. Consider the DFN package dimensions for PCB layout constraints. Evaluate the SPI interface speed requirements against the available operating voltage ranges to determine optimal clock frequency settings.
