Designers of the 56F8345 subscribe to the philosophy
that you can never have enough of a good thing. That’s
why they’ve added more on-chip Flash memory (up to
144 KB), pulse-width modulation (PWM) outputs,
analog-to-digital converter (ADC) inputs, timer channels
and quadrature decoders to the peripherals found in
smaller members of the device family. With these
additions, an entirely different set of applications can
now benefit from the hybrid microcontroller (MCU)/DSP
capabilities of the 56800E architecture. Imagine adding
signal processing capabilities to a smart user interface
or adding sophisticated communication protocol to
an industrial control application. The possibilities are
endless, especially when you consider that you
can have access to these advanced features at
extreme temperatures.
