Detailed Description for BR25H256NUX-5ACTR
Product Overview
BR25H256NUX-5ACTR from Rohm Semiconductor is a non-volatile EEPROM memory IC for embedded systems that must retain data when power is removed. The device provides 256Kbit of memory organized as 32K x 8 and uses an SPI interface with a clock frequency of 20 MHz. Its write cycle time for word or page operations is 3.5ms, and it operates from a 1.7V to 5.5V supply. The package is an 8-UFDFN exposed-pad surface-mount component, identified as VSON008X2030, with an operating temperature range of -40°C to 125°C. The part has an Automotive grade and AEC-Q100 qualification.
Key Features
- 256Kbit EEPROM memory with 32K x 8 organization
- SPI interface with 20 MHz clock frequency
- 1.7V to 5.5V supply voltage range
- -40°C to 125°C operating temperature range
- 3.5ms word or page write cycle time
- Automotive grade with AEC-Q100 qualification
- 8-UFDFN exposed-pad surface-mount package, VSON008X2030
Applications
- Embedded systems that store configuration, calibration, or identification data across power cycles
- Automotive electronic modules requiring non-volatile data retention
Design & Procurement Notes
Design considerations include matching the 1.7V to 5.5V supply range, respecting the 20 MHz SPI clock frequency, and allowing 3.5ms for word or page write operations in firmware. The 8-UFDFN exposed-pad VSON008X2030 package requires surface-mount assembly and footprint compatibility. For vehicle-related use, the Automotive grade and AEC-Q100 qualification should be evaluated against the system requirements. The -40°C to 125°C operating range supports applications exposed to wide ambient variations, while the 32K x 8 organization helps define address and data handling in the controller.
