128 Kbit SPI EEPROM with AEC-Q100 qualification
The ROHM Semiconductor BR25H128F-2CE2 is a 128 Kbit SPI EEPROM organized as 16K x 8, clocked at 10 MHz over the SPI bus.
Automotive temperature grade and write-cycle timing
The 4 ms page write cycle is the budget for firmware-update or calibration-data commit operations; a full 16 Kbyte page write takes 4 ms, so a 128 Kbit firmware sector update at 10 MHz SPI completes in about 32 ms plus overhead.
Active lifecycle and compliance posture
ROHS3 compliant per, covering the EU RoHS exemption list through the current revision.
