AT24C02C-PUM-TUDI

Tudi · EEPROM · DIP-8

AT24C02C-PUM-TUDI from Tudi, in a DIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A0 input Device address input hard-wired to set the chip's bus address; it is compared against the device address word and is biased low internally if left floating.
2 A1 input Device address input hard-wired to set the chip's bus address; it is compared against the device address word and is biased low internally if left floating.
3 A2 input Device address input hard-wired to set the chip's bus address, allowing up to eight devices on one bus; it is biased low internally if left floating.
4 GND power_in Ground reference for the device.
5 SDA bidirectional Bidirectional serial data pin; it is open-drain driven and may be wire-ORed with other open-drain or open-collector devices.
6 SCL input Serial clock input; data is clocked into the device on the positive edge and out of the device on the negative edge.
7 WP input Write protect input: tying it to GND allows normal read/write operation, while tying it to VCC enables write protection of the full array.
8 VCC power_in Power supply pin; the datasheet specifies VCC from 1.7V to 5.5V (1.7V to 5.5V at 400kHz, 2.5V to 5.5V at 1MHz).
