AT24C01C-XHM-T-TUDI

Tudi · EEPROM · TSSOP-8

AT24C01C-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, hardwired to set the chip's bus address; an internal circuit biases it low if left floating.
2 A1 input Device address input, hardwired to set the chip's bus address; an internal circuit biases it low if left floating.
3 A2 input Device address input, hardwired to set the chip's bus address; an internal circuit biases it low if left floating.
4 GND power_in Ground reference for the device; the write protect pin must be connected to GND for normal read/write operation.
5 SDA bidirectional Open-drain serial data pin that may change only while SCL is low and may be wire-ORed with other open-drain devices.
6 SCL input Serial clock input that clocks data into the device on its positive edge and out on its negative edge.
7 WP input Write protect input: connected to VCC it enables hardware write protection of the full array, and connected to GND it allows normal read/write operations.
8 VCC power_in Power supply, 1.7 V to 5.5 V at 400 kHz and 2.5 V to 5.5 V at 1 MHz.
