4 Hardware Configuration
Pins of SPI and UART interfaces, SAVE, RESET, WK, INT and OTEMP are prepared for galvanic insulation with optical
coupler. MISO, TXD, SAVE, RESET, WK, INT and OTEMP can provide a current of 5 mA for driving a diode of an opti-
cal coupler in case of VIO = 5 V.
For lower power consumption set VIO_SW bit in PS_CTRL register.
4.1 PCB Design Rules
Remark! The layout example is incomplete! The layout only gives an example about the placement of the DC/DC
converter components, the external capacitors and GND routing.
ELMOS Semiconductor AG reserves the right to change the detail specifications as may be required to permit improvements in the design of its products.
