BR24G1MFJ-3AGTE2 from ROHM Semicon, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A0 | input | Slave address setting on the BR24G128/256-3A; on the BR24G1M-3A it is 'Don't use' and may be set to H, L or Hi-Z, while A0 to A2 must not be left open when used for addressing. |
| 2 | A1 | input | Slave address setting input, which must not be left open. |
| 3 | A2 | input | Slave address setting input, which must not be left open. |
| 4 | GND | power_in | Reference voltage for all inputs and outputs, 0V. |
| 5 | SDA | bidirectional | Serial data input and output for the I2C bus. |
| 6 | SCL | input | Serial clock input for the I2C bus; inputs are read on the rising edge of SCL and data is output in sync with its falling edge. |
| 7 | WP | input | Write protect terminal that controls write operations, with setup and hold timing given for write execution and write cancel. |
| 8 | VCC | power_in | Connect the power source; the single supply operates from 1.7V to 5.5V. |
