Description
BR25H010FVM-2CTR is a 1-Mbit I2C serial EEPROM from ROHM (BR25H family). It provides non-volatile storage for microcontroller configuration, calibration data, IDs, and other small data blocks in embedded systems.
Key points:
- I2C two-wire interface for data and address; supports multiple devices on a bus using A0–A2 hardware address pins.
- Memory organization: about 128 KB (1 Mbit) of storage with random-access read/write.
- Features include page write capability, write-cycle control, and low-power operation.
- Suitable for automotive, industrial, and general consumer electronics where compact, reliable memory is needed.
- Package code “-2CTR” indicates a specific ROHM packaging variant suitable for compact PCB layouts.
Tip: Device address typically ranges with A0–A2 pins, e.g., 0x50–0x57 on the I2C bus, depending on hardware configuration. For exact electrical specs (voltage, timing, endurance, package dimensions), consult the BR25H010FVM-2CTR datasheet.
