908E626
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
• Pb-free packaging designated by suffix code EK
