A1335LLETR-T from Allegro MicroSystems LLC, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DGND | power_in | Digital ground terminal. |
| 2 | BYP | power_out | Internal bypass node; connect 0.1 µF capacitor to DGND for power supply filtering. |
| 3 | DGND | power_in | Digital ground terminal. |
| 4 | NC | unconnected | Not Connected; connect to GND for ESD protection. |
| 5 | VCC | power_in | Power supply input, 4.5 to 5.5 V nominal, also used for EEPROM writing pulses and Manchester serial interface. |
| 6 | NC | unconnected | Not Connected; connect to GND for ESD protection. |
| 7 | AGND | power_in | Analog ground terminal. |
| 8 | ISEL | input | Interface mode selection input; set low for I2C/SENT mode or high for SPI mode. |
| 9 | SENT | tri_state | SENT transmission output terminal (open-drain); requires pull-up resistor 5 to 50 kΩ to supply voltage. |
| 10 | SDA/MISO | bidirectional | I2C data terminal and SPI MISO (open-drain); bidirectional in I2C mode with external pull-up to 3.3 V required. |
| 11 | SCL/SCLK | input | Serial clock input (I2C: SCL maximum 400 kHz, SPI: SCLK maximum 10 MHz) with external pull-up to 3.3 V required. |
| 12 | SA1/MOSI | input | I2C slave address bit 1 input (tie to BYP for 1 or DGND for 0); SPI Master Output/Slave Input terminal; Manchester protocol MSB. |
| 13 | SA0/CS | input | I2C slave address bit 0 input (tie to BYP for 1 or DGND for 0); SPI active-low chip select input; Manchester protocol LSB. |
| 14 | DGND | power_in | Digital ground terminal. |
