BR93A56RFVM-WMTR

Product Overview

The Rohm Semiconductor BR93A56RFVM-WMTR is a non-volatile EEPROM memory IC with 2 Kbit capacity organized as 128 x 16. It communicates through a Microwire serial interface at a 2 MHz clock frequency and operates from a 2.5 V to 5.5 V supply. The device uses an 8-MSOP surface-mount package and is rated for -40°C to 105°C ambient. It carries AEC-Q100 qualification and an automotive grade designation.

Key Features

• 2 Kbit non-volatile EEPROM memory organized as 128 x 16
• Microwire serial interface with 2 MHz clock frequency
• Word or page write cycle time of 5 ms
• Supply voltage range of 2.5 V to 5.5 V
• Operating temperature range of -40°C to 105°C (TA)
• Surface-mount 8-MSOP package with 2.80 mm width
• AEC-Q100 qualified with automotive grade designation

Applications

• Automotive electronic control units requiring non-volatile storage of configuration parameters or calibration data
• Industrial control assemblies using a Microwire EEPROM to retain device settings across power cycles
• Embedded controller boards with 2.5 V to 5.5 V supply rails and a surface-mount 8-MSOP memory footprint

Design & Procurement Notes

When selecting BR93A56RFVM-WMTR, verify that the host controller supports Microwire communication and 2 MHz clock timing, and that the system supply remains within 2.5 V to 5.5 V. The 8-MSOP surface-mount package and 2.80 mm width should be checked against the PCB footprint and assembly process. The -40°C to 105°C (TA) operating range and AEC-Q100 qualification are relevant for automotive-grade designs, while final system-level compliance remains the designer's responsibility.
