CAT24C01YI-GT3A-TUDI

Tudi · EEPROM · TSSOP-8

CAT24C01YI-GT3A-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 (hard-wired device address bit; internally biased to logic low if left floating), allowing up to eight devices on one bus.
2 A1 input Address input (hard-wired device address bit; internally biased to logic low if left floating), allowing up to eight devices on one bus.
3 A2 input Address input (hard-wired device address bit; internally biased to logic low if left floating), allowing up to eight devices on one bus.
4 GND power_in Ground.
5 SDA bidirectional Bidirectional serial data pin, open-drain driven, may be wire-ORed with other open-drain or open-collector devices.
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.
