Compared to the sibling BR93H86RF-WCE2 which runs at 1.25 MHz, this part offers a 60% faster bus clock, which matters when the host controller polls the EEPROM during a tight power-up sequence or when storing multiple calibration maps. The write cycle time is 4 ms per word or page, so the bus speed advantage is on the read side — writes are still gated by the internal programming pulse. ## Package and footprint — 8-TSSOP-B Housed in an 8-TSSOP (4.40 mm width) with the supplier device package designated 8-TSSOP-B, this is a surface-mount part.","metaTitle":"BR93H86RFVT-2CE2 Automotive EEPROM, 16Kbit Microwire 2 MHz","metaDescription":"ROHM BR93H86RFVT-2CE2 automotive AEC-Q100 EEPROM, 16Kbit (1K x 16), Microwire interface, 2 MHz clock, -40°C to 125°C, 8-TSSOP-B.
