AT24C04CDBVRG

HANSCHIP semiconductor · EEPROM · SOT-23-5

AT24C04CDBVRG from HANSCHIP semiconductor, in a SOT-23-5. 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 SCL input Serial Clock input for the 2-wire I2C interface. Provides the clock to the device and controls data flow; SDA input is latched on the rising edge of SCL and output data is clocked out on the falling edge. Requires an external pull-up resistor to VCC. Schmitt-trigger and spike-filtered input.
2 GND power_in Ground reference for the power supply. Must be connected to the system ground.
3 SDA bidirectional Serial Data line for the 2-wire I2C interface. Open-drain bidirectional pin used to serially transfer command, address and data bytes; requires an external pull-up resistor to VCC. Schmitt-trigger and spike-filtered input.
4 VCC power_in Device power supply, 1.7 V to 5.5 V (absolute max +6.0 V). A local decoupling capacitor to GND is recommended. Operations at invalid VCC levels may produce spurious results.
5 WP input Hardware Write Protection input. When tied to VCC, the entire memory array (and Identification Page) becomes write-protected (read-only); when tied to GND, write operations are enabled. Floating input is internally pulled down to GND. When driven high, device/word-address bytes are still acknowledged but data bytes are not.
