Simulation model
A behavioural model implements the interface of the chip (registers, protocol, timing) at its pins. The pins are connected to the analog circuit like CMOS pins.

Pins 10
| Pin | Name | Use |
|---|---|---|
| 2 | SCLInput pin | I²C clock: sensors, displays; pull-up (about 4.7 kΩ) to the supply |
| 3 | SDAI/O pin | I²C data: pull-up (about 4.7 kΩ) to the supply |
| 5 | ENInput pin | Enable: high = active (tie high or drive from a GPIO) |
| 4 | IN/TRIGInput pin | Trigger / PWM / analog input, depending on the mode |
| 7 | OUT+Output pin | Motor output +: to the LRA/ERM |
| 9 | OUT−Output pin | Motor output −: to the LRA/ERM |
| 10 | VDDSupply pin | Supply 2–5.2 V: 1 µF to GND |
| 6 | VDD/NCSupply pin | Supply (second pin) |
| 1 | REGOutput pin | Internal regulator: 1 µF to GND |
| 8 | GNDGround pin | Ground |
