General Description
PSoC® 4 is a scalable and reconfigurable platform architecture for
a family of mixed-signal programmable embedded system controllers
with an ARM® Cortex™-M0 CPU. It combines programmable and
reconfigurable analog and digital blocks with flexible automatic
routing. The PSoC 4100 product family, based on this platform, is a
combination of a microcontroller with digital program mable logic,
high-performance analog-to-digital conversion, opamps with
Comparator mode, and standard communication and timing peripherals.
The PSoC 4100 products will be fully upward compatible with members
of the PSoC 4 platform for new applications and design needs. The
programmable analog and digital sub-systems allow flexibility and
in-field tuning of the design.
