BR93A66RFVT-WME2

Memory IC Overview

The BR93A66RFVT-WME2 is an automotive-grade Microwire bus EEPROM with a 4kbit (256x16bit) capacity. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 2MHz. The device features a TSSOP-B8 package and meets AEC-Q100 standards for functional safety support. Key electrical parameters include a maximum standby current of 2μA, a write cycle time of 5ms, and data retention exceeding 40 years across an operating temperature range of -40°C to +105°C.

Memory IC Feature Summary

• Automotive-grade reliability supporting functional safety analysis
• High-density 16-bit word format storage architecture
• Extended data retention capability for long-term durability

Memory IC Applications

• Automotive electronic control unit configuration storage
• Vehicle system parameter calibration memory
• Functional safety-related data logging applications

Memory IC Procurement Notes

Verify the specific suffix WME2 against official ROHM documentation to confirm package type and tape-and-reel specifications. Confirm AEC-Q100 qualification status directly from the datasheet. Ensure compatibility with existing Microwire interface requirements before procurement.

Memory IC Selection Notes

Select this component when a 16-bit word organization is required for automotive applications. Verify that the Microwire interface aligns with the host controller's serial communication capabilities. Consider the TSSOP-B8 package constraints for PCB layout and thermal management in confined automotive spaces.

Memory IC Part Context

This part belongs to the BR93A series of high-reliability EEPROMs designed specifically for automotive environments. It complements other variants in the family by offering 4kbit density with 16-bit word width, distinguishing it from 8-bit or lower-density options within the same Microwire interface category.

Memory IC Replacement Considerations

Check for BR93A66RFJ-WME2 if SOP-J-8 packaging is preferred over TSSOP-B8. Verify pinout compatibility before substituting with other BR93A series parts.
