Freescale Semiconductor Technical Data Integrated Stepper Motor Driver with Embedded MCU and LIN Serial Communication Document number: MM908E626 Rev. 11.0, 2/2013 908E626 The 908E626 is an integrated single package solution that includes a high performance HC08 microcontroller with a SMARTMOS analog control IC. The HC08 includes flash memory, a timer, enhanced serial communications interface (ESCI), an analog-to-digital converter (ADC), internal serial peripheral interface (SPI), and an internal clock generator (ICG) module. The analog control die provides fully protected H-Bridge outputs, voltage regulator, autonomous watchdog, and local interconnect network (LIN) physical layer. The single package solution, together with LIN, provides optimal application performance adjustments and space-saving PCB design. It is well-suited for the control of automotive stepper applications like climate control and light-leveling.
