AT24C08D-XHM-T-TUDI

Tudi · EEPROM · TSSOP-8

AT24C08D-XHM-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 Device address input, hard-wired; on the 8K device (AT24C08) A0 is a no-connect and is not used for device addressing.
2 A1 input Device address input, hard-wired; on the 8K device (AT24C08) A1 is a no-connect and is not used for device addressing.
3 A2 input Device address input that must match the hard-wired A2 bit of the device address word on the 8K device.
4 GND power_in Ground.
5 SDA bidirectional Bi-directional serial data pin, open-drain driven and may be wire-ORed with other open-drain or open-collector devices.
6 SCL input Serial clock input that positive-edge clocks data into the EEPROM and negative-edge clocks data out.
7 WP input Write protect input: normal read/write operation when connected to GND, write protection enabled when connected to VCC.
8 VCC power_in Power supply, 1.7V to 5.5V.
