and provide enhanced system standby functionality with programmable local and remote
wake-up capability.
The microcontrollers of the STM8AF and STM8AL boards communicate with the
L99PM62GXP IC through the SPI interface, that allows control and diagnosis of the device.
A lot of features are offered to control low and high-side drivers using the embedded and
configurable PWM timers, window watchdog, wake-up capability. Some of their outputs are
available at external headers of the STM8AF and STM8AL boards. This device is a power
SS0-36-pin package.
Figure 5 illustrates the L99PM62GXP block diagram. For further information on the
L99PM62GXP device and to explore its numerous capabilities, please refer to datasheet
available at www.st.com.
