11 / 164 page  TLE9263QX Pin Configuration Data Sheet 11 Rev. 1.1, 2014-09-26 3.3 Hints for Unused Pins It must be ensured that the correct configurations are also selected, i.e. in case functions are not used that they are disabled via SPI: • WK1/2/3: connect to GND and disable WK inputs via SPI • HSx: leave open • LINx, RXDLINx, TXDLINx, CANH/L, RXDCAN, TXDCAN: leave all pins open • RO / FOx: leave open • INT: leave open • TEST: connect to GND during power-up to activate SBC Development Mode; connect to VS or leave open for normal user mode operation • VCC2: leave open and keep disabled • VCC3: See Chapter 8.5 • VCAN: connect to VCC1 • n.c.: not connected; internally not bonded; connect to GND • If unused pins are routed to an external connector which leaves the ECU, then these pins should have provision for a zero ohm jumper (depopulated if unused) or ESD protection. 3.4 Hints for Alternate Pin Functions In case of alternate pin functions, selectable via SPI, it must be ensured that the correct configurations are also selected via SPI, in case it is not done automatically. Please consult the respective chapter. In addition, following topics shall be considered: • WK1..2: The pins can be either used as HV wake / voltage monitoring inputs or for a voltage measurement function (via bit WK_MEAS). In the second case, the WK1..2 pins shall not be used / assigned for any wake detection nor cyclic sense functionality, i.e. WK1 and WK2 must be disabled in the register WK_CTRL_2 and the level information is to be ignored in the register WK_LVL_STAT. • FO2..3: The pins can also be configured as GPIOs in the GPIO_CTRL register. In this case, the pins shall not be used for any fail output functionality. The default function after Power on Reset (POR) is FOx. |
