# ZD24C16A-XGMT

**Zetta** · EEPROM · TSSOP-8

ZD24C16A-XGMT from Zetta, in a TSSOP-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: not bonded to a die pad; can be connected to GND or left floating (on the 16K device the A2/A1/A0 bits are used for memory page addressing, not device address). |
| 2 | NC | unconnected | No Connect: not bonded to a die pad; can be connected to GND or left floating (on the 16K device the A2/A1/A0 bits are used for memory page addressing, not device address). |
| 3 | NC | unconnected | No Connect: not bonded to a die pad; can be connected to GND or left floating (on the 16K device the A2/A1/A0 bits are used for memory page addressing, not device address). |
| 4 | GND | power_in | Ground reference for the power supply; should be connected to the system ground. |
| 5 | SDA | bidirectional | Serial Data: open-drain bidirectional pin that needs an external pull-up resistor (not to exceed 10 kΩ) and may be wire-ORed with other open-drain or open-collector devices on the bus. |
| 6 | SCL | input | Serial Clock input: command and input data on SDA are latched on the rising edge of SCL and output data is clocked out on the falling edge; must be forced high or pulled high with an external pull-up when the bus is idle. |
| 7 | WP | input | Write Protect (active high): connect to GND for normal write operations; connected to VCC, all write operations to the memory are inhibited; internally pulled down to GND if not driven. |
| 8 | VCC | power_in | Device power supply (1.7V to 5.5V operating range); operation at invalid VCC voltages may produce spurious results and should not be attempted. |
