AT24C16B-TH-T-TUDI

Tudi · EEPROM · TSSOP-8

AT24C16B-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 Device address input listed in the pin table, but Section 3 states that on the 16K device A0 is no connect and the bits are used for memory page addressing.
2 A1 input Device address input listed in the pin table, but Section 3 states that on the 16K device A1 is no connect and the bits are used for memory page addressing.
3 A2 input Device address input listed in the pin table, but Section 3 states that on the 16K device A2 is no connect and the bits are used for memory page addressing.
4 GND power_in Ground reference for the device; the datasheet specifies absolute input/output voltage limits of GND-0.3V to VCC+0.3V.
5 SDA bidirectional Open-drain bidirectional serial data pin that is normally pulled high externally and may be wire-ORed with other open-drain or open-collector devices; data may change only while SCL is low.
6 SCL input Serial clock input where data is clocked into the device on the positive edge and clocked out on the negative edge, with a maximum clock frequency of 400 kHz at 1.7V to 2.5V or 1000 kHz at 2.5V to 5.5V.
7 WP input Write protect input: connecting it to GND allows normal read/write operation, while connecting it to VCC enables write protection of the full array.
8 VCC power_in Power supply, specified from 1.7V to 5.5V for normal operation with absolute maximum DC supply of -0.3V to +6.5V.
