Surface-mount, 1.27 mm pitch — the footprint is standard enough that a rework station can lift this part without lifting the pad, provided the board has been baked to MSL spec before the hot air hits it. At 10 MHz SPI clock, the bus timing margins are comfortable for a 4-layer board with short traces; a 2-layer layout works if the SPI trace is kept under 50 mm and away from switching noise. ## Temperature grade and the under-hood decision An engine-bay ECU or transmission controller that sees 105°C on a summer-grade road still has 20°C of margin before the silicon hits its abs-max junction. The 256Kbit density (organized 32K x 8) holds calibration tables, fault logs, or VIN data that must survive a power cycle. Write cycle time is 4 ms per word or page — budget this into the firmware update routine. A full 256Kbit rewrite at 4 ms per page (32 pages of 8 bytes each) takes about 128 ms; the part is busy during that window and the SPI bus must not be accessed.","metaTitle":"BR25H256F-2ACE2 ROHM 256Kbit SPI EEPROM, AEC-Q100, 8-SOP","metaDescription":"ROHM BR25H256F-2ACE2 automotive EEPROM, 256Kbit SPI 10MHz, -40 to 125°C, 8-SOP.
