Detailed Description for BR25H640NUX-5ACTR
Product Overview
The BR25H640NUX-5ACTR from Rohm Semiconductor is a 64Kbit nonvolatile EEPROM memory IC with an SPI interface. It is organized as 8K x 8 bits and operates from a 1.7V to 5.5V supply. The device supports a 20 MHz clock frequency and has a word or page write cycle time of 3.5ms. The device uses an 8-UFDFN exposed pad surface-mount package, also identified as VSON008X2030, and is rated for an operating temperature range of -40°C to 125°C TA. The part carries an Automotive grade and AEC-Q100 qualification.
Key Features
- 64Kbit nonvolatile EEPROM memory with 8K x 8 organization
- SPI serial interface supporting a 20 MHz clock frequency
- Operating supply voltage range of 1.7V to 5.5V
- Word or page write cycle time of 3.5ms
- Automotive grade device with AEC-Q100 qualification
- 8-UFDFN exposed pad surface-mount package, VSON008X2030
- Operating temperature range of -40°C to 125°C TA
Applications
- Embedded systems that retain configuration, calibration, or identification data after power removal
- Automotive electronic modules that use an AEC-Q100 qualified EEPROM for parameter storage
- Data logging circuits that store 64Kbit of recorded values across an SPI interface
Design & Procurement Notes
When selecting this device, verify that the host SPI bus is compatible with the 20 MHz clock frequency and that firmware accounts for the 3.5ms word or page write cycle time. Confirm the system supply remains within 1.7V to 5.5V and the ambient temperature stays within -40°C to 125°C TA. The 8-UFDFN exposed pad package requires appropriate surface-mount land patterns and pad connections, and the 8K x 8 organization should match the required 64Kbit EEPROM capacity and data width. Use the Automotive grade and AEC-Q100 qualification as a selection criterion when the target system requires that grade.
