AT24C02M

HGSEMI · EEPROM · SOP-8

AT24C02M from HGSEMI, in a SOP-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 slave address input bit 0. Hardware addressing pin allowing up to 8 devices on one I2C bus. Internally pulled down to Vss if left floating. Schmitt-trigger input.
2 E1 input Device slave address input bit 1. Hardware addressing pin allowing up to 8 devices on one I2C bus. Internally pulled down to Vss if left floating.
3 E2 input Device slave address input bit 2. Hardware addressing pin allowing up to 8 devices on one I2C bus. Internally pulled down to Vss if left floating.
4 Vss power_in Ground reference for the Vcc supply voltage.
5 SDA bidirectional I2C serial data input/output. Open-drain, can be wire-OR'ed with other open-drain/open-collector devices. Requires an external pull-up resistor. Input capacitance 8 pF max.
6 SCL input I2C serial clock input. Positive edge clocks data in, negative edge clocks data out. Supports up to 400 kHz (standard AC table) and 1 MHz per features summary. Schmitt-trigger, noise-filtered input.
7 WCB input Write Control (active low). Tie to Vcc to inhibit all write operations to the memory; tie to Vss for normal write operation. Internally pulled down to Vss if left floating.
8 Vcc power_in Positive supply voltage input, 1.7 V to 5.5 V. Read current 0.2 mA typ @ 400 kHz; write current 0.8 mA typ. Standby current 1 uA typ at Vcc=3.3V.
