BR93A86RFVT-WME2

Product Overview

Rohm Semiconductor BR93A86RFVT-WME2 is a non-volatile EEPROM memory IC with a 16Kbit capacity organized as 1K x 16. It uses a Microwire serial interface and supports a 2 MHz clock frequency, making it suitable for embedded systems that require retained configuration, calibration, or status data after power removal. The device operates from a 2.5 V to 5.5 V supply and is specified for ambient temperatures from -40°C to 105°C. It is automotive grade and has AEC-Q100 qualification, and uses a surface-mount 8-TSSOP-B package.

Key Features

• 16Kbit EEPROM memory with 1K x 16 organization
• Non-volatile data retention for configuration and calibration values
• Microwire serial interface with 2 MHz clock frequency
• 2.5 V to 5.5 V supply voltage range
• -40°C to 105°C operating temperature range (TA)
• Automotive grade with AEC-Q100 qualification
• Surface-mount 8-TSSOP-B package
• 5 ms word or page write cycle time

Applications

• Automotive electronic control modules requiring non-volatile parameter storage
• Embedded sensor assemblies storing calibration offsets or trim data
• Battery-powered or intermittent systems that preserve configuration data when power is removed
• Microwire-based serial memory expansion in compact surface-mount designs

Design & Procurement Notes

Designers should verify that the host controller supports Microwire timing at up to 2 MHz and that system voltage remains within 2.5 V to 5.5 V. The 8-TSSOP-B footprint and surface-mount orientation affect PCB layout and rework considerations. The -40°C to 105°C ambient range and AEC-Q100 qualification are relevant for automotive-grade designs, while the 5 ms word/page write time should be considered in firmware update sequences and power-down timing. The 1K x 16 organization determines addressing and data width, so software should map memory usage accordingly.
