AT24C02D-SSHM-T-TUDI

Tudi · EEPROM · SOP-8

AT24C02D-SSHM-T-TUDI from Tudi, 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 A0 input Device address input bit 0. Hard-wired to VCC or GND to set the lower bit of the I2C slave address (1010_A2A1A0_R/W), allowing up to 8 devices on one bus. Internally biased low if left floating.
2 A1 input Device address input bit 1. Hard-wired to VCC or GND to set the middle bit of the I2C slave address. Internally biased low if left floating.
3 A2 input Device address input bit 2. Hard-wired to VCC or GND to set the upper user-selectable bit of the I2C slave address. Internally biased low if left floating.
4 GND power_in Ground reference for the device.
5 SDA bidirectional I2C serial data (bidirectional, open-drain). Requires an external pull-up resistor to VCC and may be wire-ORed with other open-drain devices on the bus.
6 SCL input I2C serial clock input. Data is clocked into the EEPROM on the positive edge and out of the EEPROM on the negative edge. Supports up to 1 MHz at VCC >= 2.5V (400 kHz at VCC >= 1.7V).
7 WP input Write-protect input. Tie to GND for normal read/write operation; tie to VCC to hardware write-protect the full 2K array.
8 VCC power_in Power supply input, 1.7V to 5.5V (2.5V to 5.5V for 1 MHz operation). Typical read current 0.14 mA @400 kHz, write current 0.28 mA, standby current ~0.03 uA.
