AT24C01D-SSHM-B

Microchip Tech · Pre-ordered Chips · SOIC-8

AT24C01D-SSHM-B from Microchip Tech, in a SOIC-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 hard-wired to GND or VCC (up to eight devices per bus); internally pulled down to GND if left floating, but connecting to a known state is recommended.
2 A1 input Device address input hard-wired to GND or VCC (up to eight devices per bus); internally pulled down to GND if left floating, but connecting to a known state is recommended.
3 A2 input Device address input hard-wired to GND or VCC (up to eight devices per bus); internally pulled down to GND if left floating, but connecting to a known state is recommended.
4 GND power_in Ground reference for the power supply, to be connected to system ground.
5 SDA bidirectional Open-drain bidirectional serial data pin requiring an external pull-up resistor (not to exceed 10 kΩ), wire-OR capable with other open-drain devices on the bus.
6 SCL input Serial clock input that controls data flow; input data is latched on the rising edge and output data is clocked out on the falling edge, and it must be forced high or pulled high when the bus is idle.
7 WP input Write-protect input: connected to GND allows normal writes, connected to VCC inhibits all writes to the full array; internally pulled down to GND if left floating.
8 VCC power_in Device power supply pin, operating from 1.7V to 3.6V; operation at invalid VCC voltages may produce spurious results.
