Pinout
The product information does not explicitly mention the pin count or function of the ATA663231-GBQW. However, since it's a LIN Transceiver, we can infer that it has pins for transmitting (TXD) and receiving (RXD) data on the LIN bus.
According to Microchip's documentation, the VDFN-8 package typically has 8 pins. The pinout is not explicitly mentioned in the provided information, but it's common for LIN transceivers to have a similar pinout, such as:
- TXD: Transmit Data
- RXD: Receive Data
- VS: Supply voltage input
- VCC: Regulated voltage output
- NRES: Open-drain reset output
- GND: Ground
Please note that the exact pinout may vary depending on the specific device and manufacturer.
