AT24C04C-SSHM-B

Microchip Tech · Pre-ordered Chips · SOIC-8

AT24C04C-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 NC unconnected No connect pin with no internal function stated.
2 A1 input Device address input hardwired to GND or VCC on the AT24C04C (NC on AT24C08C); if left floating it is internally pulled down to GND, and connecting it to a known state is recommended.
3 A2 input Device address input hardwired to GND or VCC; if left floating it is internally pulled down to GND, and connecting it 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 that needs an external pull-up resistor not exceeding 10 kΩ.
6 SCL input Serial clock input that latches command and input data on the rising edge and clocks output data out on the falling edge; it must be forced high or pulled high when the bus is idle.
7 WP input Write-protect input: at GND it allows normal write operations, and at VCC it inhibits all writes to the full array; if left floating it is internally pulled down to GND.
8 VCC power_in Device power supply pin, operating from 1.7V to 5.5V.

CAD (KiCad official)

  • Symbol: AT24C04C-SSHM-B
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: at24c04c-sshm-b-etched.step / at24c04c-sshm-b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); at24c04c-sshm-b.step / at24c04c-sshm-b.glb are the bare package body.
