Overview
The 908E621 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), a
10 bit analog-to-digital converter (ADC),
internal serial peripheral interface (SPI), and
an internal clock generator module (ICG).
The analog control die provides four halfbridge 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.
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 high end mirrors.
