Automotive-grade 2Kbit SPI EEPROM for harsh environments
The ROHM BR25H020FVT-2CE2 is a 2Kbit serial EEPROM with an SPI interface, designed for automotive and industrial applications that demand reliability over a wide temperature range. It is AEC-Q100 qualified, operates from 2.5V to 5.5V, and supports a 10 MHz clock frequency. The memory is organized as 256 x 8 bits and is housed in an 8-TSSOP-B surface-mount package.
The 2.5V to 5.5V supply span lets this part drop straight into a 3.3V MCU rail or a 5V legacy bus without a level translator — one less component on the BOM. Write-cycle time is 4 ms per word or page, which is typical for this density class. For applications that log data frequently — calibration constants, fault codes, trim values — the 4 ms write window is fast enough for most parameter updates but not for streaming writes.
Package and footprint note
The 8-TSSOP-B (0.173" body width, 4.40 mm) is a common footprint shared across ROHM's automotive serial EEPROM family. The supplier device package is 8-TSSOP-B.
Lifecycle and compliance
It is ROHS3 compliant.
