HTCSEMI · Real Time Clocks · DIP-8
HT1307ANZ from HTCSEMI, 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 | X1 | input | Connection pin for the quartz resonator (32.768 kHz crystal, with load capacitance CLX of 12.5 pF per the datasheet timing table). |
| 2 | X2 | input | Connection pin for the quartz resonator, paired with X1 (load capacitance CLX of 12.5 pF per the datasheet timing table). |
| 3 | VBAT | power_in | Battery input pin; the stated normal battery voltage range is 2.0 V to 3.5 V, with an absolute limit of -0.5 V to 7.0 V. |
| 4 | GND | power_in | Ground pin; all datasheet voltages are referenced to ground. |
| 5 | SDA | bidirectional | Serial data input/output for the two-wire bus; low-level output voltage is at most 0.4 V at 5 mA, and I/O capacitance is 10 pF max. |
| 6 | SCL | input | Input for the serial bus clock; bus clock frequency is 0 to 100 kHz (normal mode only), and input leakage is limited to 1 µA. |
| 7 | SQW/OUT | output | Programmable rectangular-wave output selectable as 1 Hz, 4.096 kHz, 8.192 kHz or 32.768 kHz via the RS bits, with output-low voltage of at most 0.4 V. |
| 8 | VCC | power_in | Main power supply pin; the normal operating supply range is 4.5 V to 5.5 V, with an absolute limit of -0.5 V to 7.0 V. |
