AT24C16M

HGSEMI · EEPROM · SOP-8

AT24C16M from HGSEMI, in a SOP-8. 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 NC unconnected No internal connection. Leave floating or tie to any potential; the pin has no function in the 24C16 variant.
2 NC unconnected No internal connection. Leave floating or tie to any potential; the pin has no function in the 24C16 variant.
3 NC unconnected No internal connection on the 24C16 (this pin is E2 slave-address input on the 24C08 variant only).
4 VSS power_in Ground reference for the VCC supply. Connect to the system 0 V rail.
5 SDA bidirectional I2C serial data input/output. Open-drain output; requires an external pull-up resistor to VCC and may be wire-ORed with other open-drain devices on the bus. VOL = 0.2 V at IOL = 0.15 mA (VCC = 1.7 V) or 0.4 V at IOL = 2.1 mA (VCC = 3.0 V).
6 SCL input I2C serial clock input. Positive-edge clocks data in, negative-edge clocks data out. Schmitt-trigger, noise-filtered input; requires external pull-up per I2C bus specification. Supports up to 400 kHz (1.7-5.5 V) or 1 MHz.
7 WCB input Write Control input, active-low enable for write operations. Tie to VCC to inhibit all writes to the memory array; tie to VSS (or leave floating - internal pull-down to VSS) to allow normal writes.
8 VCC power_in Positive supply voltage, 1.7 V to 5.5 V. Standby current typ 0.5-1.0 uA; read current typ 0.2 mA; write current typ 0.8 mA at 400 kHz.
