PSoC® 3: CY8C32 Family
Data Sheet
High resolution delta-sigma ADC.
8. Analog Subsystem
One 8-bit DAC that provides either voltage or current output.
The analog programmable system creates application specific
combinations of both standard and advanced analog signal
processing blocks. These blocks are then interconnected to
each other and also to any pin on the device, providing a high
level of design flexibility and IP security. The features of the
analog subsystem are outlined here to provide an overview of
capabilities and architecture.
Two comparators with optional connection to configurable LUT
outputs.
CapSense subsystem to enable capacitive touch sensing.
Precision reference for generating an accurate analog voltage
for internal analog blocks.
Flexible, configurable analog routing architecture provided by
analog globals, analog mux bus, and analog local buses.

The PSoC Creator software program provides a user friendly interface to configure the analog connections between the GPIO and
various analog resources and connections from one analog resource to another. PSoC Creator also provides component libraries that
allow you to configure the various analog blocks to perform application specific functions. The tool also generates API interface
libraries that allow you to write firmware that allows the communication between the analog peripheral and CPU/Memory.
