AT24CS64-SSHM-B

Microchip Tech · EEPROM · SOIC-8

AT24CS64-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 Hard-wired device address input (to GND or VCC) that is internally pulled down to GND if left floating, so Microchip recommends connecting it to a known state.
2 A1 input Hard-wired device address input (to GND or VCC) that is internally pulled down to GND if left floating, so Microchip recommends connecting it to a known state.
3 A2 input Hard-wired device address input (to GND or VCC) that is internally pulled down to GND if left floating, so Microchip recommends connecting it to a known state.
4 GND power_in Ground reference for the power supply, which should be connected to the system ground.
5 SDA bidirectional Open-drain bidirectional serial data pin that must be pulled high with an external pull-up resistor not exceeding 10 kΩ.
6 SCL input Serial clock input that latches SDA input data on its rising edge and must be forced high when the bus is idle or pulled high with an external pull-up resistor.
7 WP input Write-protect input: connection to GND allows normal write operations, while connection to VCC inhibits writes to the full array, and it is internally pulled down to GND if left floating.
8 VCC power_in Device power supply pin; operations at invalid VCC voltages may produce spurious results and should not be attempted.

CAD (KiCad official)

  • Symbol: AT24CS64-SSHM-B
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: at24cs64-sshm-b-etched.step / at24cs64-sshm-b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); at24cs64-sshm-b.step / at24cs64-sshm-b.glb are the bare package body.
