ROHM · EEPROM · SOIC-8

BR24T64FJ-WE2 from ROHM, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A0 input Slave address setting bit 0. Sets least significant bit of the device address on the I2C bus for multi-device addressing. Must not be left open - tie to VCC or GND.
2 A1 input Slave address setting bit 1. Sets middle bit of the device address on the I2C bus. Must not be left open - tie to VCC or GND.
3 A2 input Slave address setting bit 2. Sets most significant address bit for the I2C slave address. Must not be left open - tie to VCC or GND.
4 GND power_in Ground reference (0V) for all inputs, outputs, and supply.
5 SDA bidirectional I2C serial data input/output. Open-drain, requires an external pull-up resistor to VCC. VOL1 = 0.4V max at IOL = 3.0mA (2.5V <= VCC <= 5.5V).
6 SCL input I2C serial clock input. Supports Fast Mode up to 400kHz. VIH >= 0.7VCC (1.7V <= VCC <= 5.5V) or 0.8VCC (1.6V <= VCC < 1.7V).
7 WP input Write protect input. When tied high, write operations to the EEPROM array are inhibited; when low, writes are permitted. tHIGH:WP >= 1.0us.
8 VCC power_in Positive supply input, 1.6V to 5.5V single-supply operation. Absolute max +6.5V. ICC = 2.0mA (write) / 0.5mA (read) at VCC=5.5V, fSCL=400kHz.
