Integrated Stepper Motor Driver
with Embedded MCU and LIN
Serial Communication
The 908E626 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), an analog-to-digital converter
(ADC), serial peripheral interface (SPI) (only internal), 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-levelling.
Features
• High-Performance M68HC08EY16 Core
•16 K Bytes of On-Chip Flash Memory
• 512 Bytes of RAM
• Internal Clock Generation Module
• Two 16-Bit, 2-Channel Timers
• 10-Bit Analog-to-Digital Converter
• Four Low RDS(ON) Half-Bridge Outputs
• 13 Microcontroller I/Os
