Overview
The MM908E622 is an integrated singlepackage 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 module.
The analog control die provides four halfbridge and three high side outputs with
diagnostic functions, an EC glass driver
circuit, 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 spacesaving PCB design. It is well-suited for the
control of automotive high-end mirrors.
