8.1 Analog Routing
The CY8C32 family of devices has a flexible analog routing
architecture that provides the capability to connect GPIOs and
different analog blocks, and also route signals between different
analog blocks. One of the strong points of this flexible routing
architecture is that it allows dynamic routing of input and output
connections to the different analog blocks.
For information on how to make pin selections for optimal analog
routing, refer to the application note,
PSoC® 5 - Pin Selection for Analog Designs.
8.1.1 Features
Document Number: 001-56955 Rev. *J
Flexible, configurable analog routing architecture
16 analog globals (AG) and two analog mux buses
(AMUXBUS) to connect GPIOs and the analog blocks
Each GPIO is connected to one analog global and one analog
mux bus

8.1.2 Functional Description
Analog globals (AGs) and analog mux buses (AMUXBUS)
provide analog connectivity between GPIOs and the various
analog blocks. There are 16 AGs in the CY8C32 family. The
analog routing architecture is divided into four quadrants as
shown in
(AGL[0..3], AGL[4..7], AGR[0..3], AGR[4..7]). Each GPIO is
connected to the corresponding AG through an analog switch.
The analog mux bus is a shared routing resource that connects
to every GPIO through an analog switch. There are two
AMUXBUS routes in CY8C32, one in the left half (AMUXBUSL)
and one in the right half (AMUXBUSR), as shown in
Eight analog local buses (abus) to route signals between the
different analog blocks

analog blocks
