SPI EEPROM for automotive parameter storage
The ROHM BR25H010FVT-2CE2 is a 1Kbit serial EEPROM with an SPI interface, organized as 128 x 8 bits. It is part of ROHM's Automotive, AEC-Q100 series, meaning it has been qualified to the AEC-Q100 stress test standard for automotive-grade ICs. The write cycle time for a word or page is 4 ms.
The 125°C ceiling covers under-hood hot spots that a 105°C or 85°C part would not survive. For outdoor industrial gear — solar inverters, off-highway vehicle controls — the same temperature range gives margin on a 105°C-rated design.
