AT24C16D-STUM-T-TUDI

Tudi · EEPROM · SOT-23-5

AT24C16D-STUM-T-TUDI from Tudi, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SCL input I2C serial clock input. Schmitt-trigger, filtered input; positive edge clocks data into the EEPROM and negative edge clocks data out. Requires an external pull-up resistor to VCC (open-drain bus). VIH >= 0.7VCC, VIL <= 0.3VCC.
2 GND power_in Ground reference (0 V) for the device. All signal and supply voltages are referenced to this pin.
3 SDA bidirectional I2C serial data line. Bi-directional, open-drain driven; may be wire-ORed with other open-drain/open-collector devices on the bus. Requires an external pull-up resistor to VCC. Data is stable while SCL is high; transitions occur only while SCL is low (except for START/STOP conditions).
4 VCC power_in Positive supply voltage input. Operating range 1.7 V to 5.5 V. Typical ICC = 0.14 mA read / 0.28 mA write at 400 kHz (VCC = 5.0 V); standby ISB1 = 0.03 uA typ. Bypass locally with a 100 nF ceramic capacitor to GND.
5 WP input Write protect input. When tied to GND, normal read/write operations are allowed. When tied to VCC, the full memory array is write-protected in hardware. Must not be left floating.
