Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OSCI | input | Oscillator input for the external 32.768kHz crystal; the OSCI absolute input range is -0.5V to VDD+0.5V. |
| 2 | OSCO | output | Oscillator output for the external 32.768kHz crystal; see note 3 on page 16 for its use. |
| 3 | INT | output | Interrupt output for the alarm and periodic timer flags, with pulse or level behavior selected by TI/TP (register 01H); the absolute output voltage limit is -0.5V to +6.5V. |
| 4 | VSS | power_in | Ground reference for the device. |
| 5 | SDA | bidirectional | I2C serial data line; VIL is 0 to 0.3VDD and VIH is 0.7VDD to VDD, with absolute limits of -0.5V to +6.5V. |
| 6 | SCL | input | I2C serial clock input, up to 400kHz; absolute input limits are -0.5V to +6.5V. |
| 7 | CLKOUT | output | Programmable clock output selectable as 32.768kHz, 1024Hz, 32Hz or 1Hz via register 0DH and enabled by the FE bit; absolute output limits are -0.5V to +6.5V. |
| 8 | VDD | power_in | Supply voltage: 1.0V to 5.5V for I2C communication and 1.8V to 5.5V at 400kHz, with absolute limits of -0.5V to +6.5V. |
