The 908E621 is an integrated single package solution that includes a high performance HC08 microcontroller with a SMARTMOSTM analog control IC. The HC08 includes flash memory, a timer, enhanced serial communications interface (ESCI), a 10 bit analog-to-digital converter (ADC), serial peripheral interface (SPI) (only internal), and an internal clock generator module (ICG). The analog control die provides four half-bridge and three high side outputs with diagnostic functions, a Hall-effect sensor input, analog inputs, voltage regulator, window watchdog, and local interconnect network (LIN) physical layer.
