CAT24C16YI-GT3A-TUDI

Tudi · EEPROM · TSSOP-8

CAT24C16YI-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 Device address input; on the 24C16 the A0, A1 and A2 pins are no connect because the three bits are used for memory page addressing.
2 A1 input Device address input; on the 24C16 the A0, A1 and A2 pins are no connect because the three bits are used for memory page addressing.
3 A2 input Device address input; on the 24C16 the A0, A1 and A2 pins are no connect because the three bits are used for memory page addressing.
4 GND power_in Ground.
5 SDA bidirectional Bidirectional serial data pin that is 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, and write protection enabled when connected to VCC.
8 VCC power_in Power supply, 1.7V to 5.5V operating range.
