HANSCHIP semiconductor · EEPROM · MSOP-8

AT24C256CDGKRG from HANSCHIP semiconductor, in a MSOP-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 E0 input Device address input bit 0. Along with E1 and E2, selects the three least-significant bits of the I2C 7-bit slave address, allowing up to eight devices on the same bus. Tie directly to VCC or GND.
2 E1 input Device address input bit 1. Along with E0 and E2, selects the three least-significant bits of the I2C 7-bit slave address. Tie directly to VCC or GND.
3 E2 input Device address input bit 2. Along with E0 and E1, selects the three least-significant bits of the I2C 7-bit slave address. Tie directly to VCC or GND.
4 GND power_in Ground reference for the power supply. Must be connected to the system ground.
5 SDA bidirectional Serial Data. Open-drain bidirectional pin used to serially transfer data to and from the device. Requires an external pull-up resistor to VCC.
6 SCL input Serial Clock. Provides the clock to the device controlling data flow. Command and input data are latched in on the rising edge of SCL; output data are clocked out on the falling edge. Requires an external pull-up resistor to VCC.
7 WP input Write Protection. When tied to VCC the entire memory array becomes write-protected (read-only); when tied to GND or left floating, write operations are enabled. Driving WP high causes data bytes to not be acknowledged.
8 VCC power_in Device power supply, 1.7V to 5.5V. Provides the source voltage to the device; operation at invalid VCC voltages may produce spurious results.
