HT4116ARMZ from HTCSEMI, in a MSOP-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 | OSCI | input | Oscillator input for the external 32.768 kHz crystal. |
| 2 | OSCO | output | Oscillator output for the external 32.768 kHz crystal. |
| 3 | VBAT | power_in | Battery supply voltage, 2.5 to 3.5 V (3 V typ.), used for backup when VCC falls below the switchover voltage VSO. |
| 4 | VSS | power_in | Ground. |
| 5 | SDA | bidirectional | Serial data address input/output of the I2C bus; requires an external pull-up resistor to a positive supply. |
| 6 | SCL | input | Serial clock input of the I2C bus (0 to 100 kHz); requires an external pull-up resistor to a positive supply. |
| 7 | FT/OUT | output | Frequency test (512 Hz) or output driver pin, open drain, requires an external pull-up resistor (pull-up supply up to 5.5 V). |
| 8 | VCC | power_in | Supply voltage, 2.0 to 5.5 V clock operating voltage. |
