Board-level memory for parameter storage and calibration data
The BR24T04F-WE2: It stores non-volatile configuration, calibration constants, or device identity data on a mixed-signal or digital board where the MCU's internal flash is reserved for firmware.
Package and footprint for PCB integration
Surface-mount assembly with a standard SOIC-8 footprint — no thermal pad or exposed paddle to route. The 5 ms write cycle time per word or page means the bus is held during writes; the host firmware must account for this delay in the I²C transaction sequence.
