PRODUCTION DATA
| PIN | TYPE(1) | DESCRIPTION | |
|---|---|---|---|
| NO. | NAME | ||
| 1 | VSUP | HV Supply In | Device supply voltage (connected to battery in series with external reverse-blocking diode) |
| 2 | LIMP | HV O | Used for LIMP home, watchdog event causes this pin to switch VSUP |
| 3 | EN/nINT | D I/O | Enable Input when in Pin Mode/Processor Interrupt when in SPI Mode (open drain) - when EN - Enable input - Setting pin high place device into normal mode and setting low is sleep mode |
| 4 | GND | GND | Ground |
| 5 | LIN | HV I/O | LIN bus single-wire transmitter and receiver |
| 6 | WDT/CLK | D I | Programmable watchdog window set input (3 levels)/SPI Clock input |
| 7 | nWDR/SDO | D O | Watchdog output trigger when in Pin Mode / SPI Responder Data Output when in SPI Mode |
| 8 | WDI/SDI | D I | Watchdog timer trigger input active on both rising and falling edges when in Pin Mode (Must be driven at all times) /SPI Responder Data Input when in SPI Mode |
| 9 | PIN/nCS | D I | Watchdog Configuration Control Set at Power Up. When tied to GND at power up device is in Pin Mode. When High or in Z-State device is in SPI Mode and this pin becomes Chip Select |
| 10 | RXD | D O | RXD output (open-drain) interface reporting state of LIN bus voltage |
| 11 | TXD | D I | TXD input interface to control state of LIN output |
| 12 | nRST/nWDR | D O | Reset output (active low)/Watchdog output trigger if programmed in SPI Mode (active low) |
| 13 | WAKE | HV I | High Voltage Local wake up pin active Low |
| 14 | VCC | Supply Out | Output voltage from integrated voltage regulator |
