ZD24C256A-SSGMT

Zetta · EEPROM · SOIC-8

ZD24C256A-SSGMT from Zetta, in a SOIC-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 A0 input Device address input bit 0. Hardwire to VCC or GND to form the least-significant bit of the 7-bit I2C slave address (device type identifier '1010' concatenated with A2/A1/A0). Allows up to eight ZD24C256A devices on one bus. Schmitt-triggered CMOS input.
2 A1 input Device address input bit 1. Hardwire to VCC or GND to form the middle bit of the hardware slave address field. Schmitt-triggered CMOS input.
3 A2 input Device address input bit 2. Hardwire to VCC or GND to form the most-significant bit of the hardware slave address field. Schmitt-triggered CMOS input.
4 GND power_in Ground reference for the power supply. Tie to system ground.
5 SDA bidirectional I2C serial data. Open-drain bidirectional line used to transfer address and data. Requires an external pull-up resistor (<=10 kOhm recommended) and may be wire-ORed with other open-drain devices on the same bus. Schmitt-triggered input.
6 SCL input I2C serial clock input from the bus master. Data on SDA is latched on the rising edge of SCL and driven out on the falling edge. Must be pulled high with an external resistor when the bus is idle. Schmitt-triggered input.
7 WP input Write Protect. Tie to GND for normal (unprotected) write operation; tie to VCC to inhibit all writes to the memory array (hardware data protection). Active high. If left floating, an internal weak pull-down biases the pin toward GND but Zetta recommends driving it to a known state.
8 VCC power_in Device power supply, 1.7 V to 5.5 V (1 MHz Fast Mode Plus operation requires >=2.5 V). Bypass locally to GND. Operating outside this range may produce spurious results.

CAD (KiCad official)

  • Symbol: ZD24C256A-SSGMT
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: zd24c256a-ssgmt-etched.step / zd24c256a-ssgmt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); zd24c256a-ssgmt.step / zd24c256a-ssgmt.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
zd24c256a-ssgmt.step 122 KB You want the bare part, or you mark your own boards.
zd24c256a-ssgmt-etched.step 2.9 MB You want the part with ZD24C256A-SSGMT already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 698 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
