The digital blocks can be connected to any GPIO through a
series of global buses that can route any signal to any pin. The
buses also enable signal multiplexing and for performing logic
operations. This configurability frees your designs from the
constraints of a fixed peripheral controller.
Digital blocks are provided in rows of four, where the number of
blocks varies by PSoC device family. This lets you the optimum
choice of system resources for your application. Family
resources are shown in the table titled PSoC Device
Characteristics on page 6.
Analog System
The analog system is composed of 12 configurable blocks, each
comprised of an opamp circuit allowing the creation of complex
analog signal flows. Analog peripherals are very flexible and can
be customized to support specific application requirements.
Some of the more common PSoC analog functions (most
available as user modules) are as follows:
■ ADCs (up to 4, with 6- to 14-bit resolution, selectable as
incremental, delta sigma, and SAR)
■ Filters (2, 4, 6, and 8 pole band pass, low pass, and notch)
■ Amplifiers (up to four, with selectable gain to 48x)
■ Instrumentation amplifiers (up to two, with selectable gain to
93x)
■ Comparators (up to four, with 16 selectable thresholds)
■ DACs (up to four, with 6- to 9-bit resolution)
■ Multiplying DACs (up to four, with 6- to 9-bit resolution)
■ High current output drivers (four with 30 mA drive as a core
resource)
■ 1.3-V reference (as a system resource)
■ DTMF dialer
■ Modulators
■ Correlators
■ Peak detectors
■ Many other topologies possible
Analog blocks are provided in columns of three, which includes
one continuous time (CT) and two switched capacitor (SC)
blocks, as shown in the following figure.
