DS1302ZN
HGSEMI · Real Time Clocks · DIP-8
DS1302ZN from HGSEMI, in a DIP-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 | VCC2 | power_in | Main power supply input; the device runs from the higher of VCC1 or VCC2, and the recommended supply range is 2.0 V to 5.5 V. |
| 2 | X1 | passive | Connection to the 32.768 kHz crystal, which should have a specified load capacitance of 6 pF. |
| 3 | X2 | passive | Connection to the 32.768 kHz crystal, which should have a specified load capacitance of 6 pF. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | RST | input | Reset/chip-enable input: driving it high starts data transfer and driving it low aborts transfer and forces I/O to high impedance, and it must be low before VCC reaches 2.5 V at power-up. |
| 6 | I/O | bidirectional | Serial data input/output pin that goes high impedance when RST is low; at VCC=5 V the logic levels are TTL compatible. |
| 7 | SCLK | input | Serial clock input: data is sampled on rising edges and output on falling edges, and SCLK must be low when RST is driven high. |
| 8 | VCC1 | power_in | Backup power supply input that keeps the clock and RAM powered when VCC2 is absent, within the 2.0 V to 5.5 V recommended range. |
