AT24C02B-TH-T-TUDI

Tudi · EEPROM · TSSOP-8

AT24C02B-TH-T-TUDI from Tudi, in a TSSOP-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 Address input A0, hard-wired device address bit; eight 2K devices may share one bus, and the pin is biased to logic low if left floating.
2 A1 input Address input A1, hard-wired device address bit; biased to logic low by an internal circuit if left floating.
3 A2 input Address input A2, hard-wired device address bit; biased to logic low by an internal circuit if left floating.
4 GND power_in Ground.
5 SDA bidirectional Serial data I/O, bi-directional and open-drain, may be wire-ORed with other open-drain or open-collector devices and needs an external pull-up.
6 SCL input Serial clock input, positive edge clocks data into the EEPROM and negative edge clocks data out.
7 WP input Write protect input; connected to GND allows normal read/write operations, connected to VCC write-protects the full array.
8 VCC power_in Power supply, 1.7V to 5.5V at 400kHz and 2.5V to 5.5V at 1MHz.
