32 Kbit I²C EEPROM — parameter storage for industrial and mixed-voltage designs
The ROHM BR24T32FVM-WTR is a 32 Kbit serial EEPROM with an I²C interface, organized as 4K x 8 bits. It stores calibration coefficients, configuration tables, serial numbers, or event logs in equipment that needs non-volatile memory that can be rewritten in-system.
Supply voltage and temperature — where this part fits the BOM
If your design lives in a -40°C cold start or a 85°C hot box, this part is rated for it.
Package and footprint — MSOP-8 on the board
Housed in an 8-MSOP package (2.80 mm width, VSSOP/MSOP footprint), this is a surface-mount part for pick-and-place assembly. The 8-MSOP is a common small-outline footprint — check your board layout for the 0.65 mm pin pitch.
Write cycle timing — 5 ms page write
That 5 ms is the time the part is busy after a write command — the I²C master must wait before sending the next command. For firmware updates or data logging, budget this delay into the sequence; it is typical for this class of serial EEPROM.
It is ROHS3 compliant, which means no exemptions for lead or other restricted substances — acceptable for EU and global markets without a waiver.
