Detailed Description for BR25H640FVT-5ACE2
Product Overview
The BR25H640FVT-5ACE2 from Rohm Semiconductor is a nonvolatile EEPROM memory IC organized as 8K x 8 for a total capacity of 64Kbit. It uses an SPI interface with a clock frequency of 20 MHz and operates from a 1.7V to 5.5V supply. The device is specified for an operating temperature range of -40°C to 125°C (TA) and is housed in an 8-TSSOP surface-mount package, 0.173 in (4.40 mm) width, with package designation 8-TSSOP-B. The part is automotive grade and AEC-Q100 qualified.
Key Features
- 64Kbit nonvolatile EEPROM with an 8K x 8 memory organization
- SPI memory interface supporting a 20 MHz clock frequency
- 1.7V to 5.5V supply voltage range
- 3.5ms write cycle time for word or page writes
- -40°C to 125°C (TA) operating temperature range
- Automotive grade and AEC-Q100 qualification
- Surface-mount 8-TSSOP package, 4.40 mm width, package designation 8-TSSOP-B
Applications
- Automotive electronic control units that need nonvolatile storage of configuration or calibration data
- Vehicle sensor modules operating in extended-temperature environments from -40°C to 125°C
- Embedded systems using an SPI host interface and a 1.7V to 5.5V supply
Design & Procurement Notes
Design considerations should focus on matching the host controller to the SPI interface and the 20 MHz clock specification, while allowing for the 3.5ms word/page write cycle in firmware timing budgets. The system supply should remain within the 1.7V to 5.5V range, and interface voltage compatibility should be confirmed against the host logic family. The 8-TSSOP surface-mount package has a 4.40 mm body width and is designated 8-TSSOP-B, so PCB land patterns and clearance should be checked accordingly. The -40°C to 125°C (TA) range and AEC-Q100 automotive grade support use in automotive electronic designs requiring serial EEPROM storage.
