A1330LLETR-P-T from Allegro MicroSystems, LLC, in a TSSOP-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 | VCC | power_in | Device power supply, specified at 4.5 to 5.5 V, and also serves as the Manchester communication input pin. |
| 2 | VOUT | bidirectional | Angle output (analog or PWM for this PWM-output variant), which also carries the Manchester output during serial communication and receives EEPROM programming pulses. |
| 3 | NC | unconnected | Not connected; the datasheet says it must be tied to GND for optimum ESD performance. |
| 4 | GND | power_in | Ground connection for the device. |
| 5 | NC | unconnected | Not connected; the datasheet says it must be tied to GND for optimum ESD performance. |
| 6 | NC | unconnected | Not connected; the datasheet says it must be tied to GND for optimum ESD performance. |
| 7 | NC | unconnected | Not connected; the datasheet says it must be tied to GND for optimum ESD performance. |
| 8 | NC | unconnected | Not connected; the datasheet says it must be tied to GND for optimum ESD performance. |
