The PSoC
erence Manual (TRM), the CY8C20x34 PSoC device does not have regular digital PSoC blocks and global interconnects that
are found in most PSoC devices. The CY8C20x34 devices have one analog resource and digital logic in addition to a fast
CPU, Flash program memory, and SRAM data memory to support various CapSense algorithms.
For the most up-to-date Ordering, Pinout, Packaging, or Electrical Specification information, refer to the PSoC device’s data

Document Organization
This manual is organized into sections and chapters, according to PSoC functionality. Each section contains a top-level archi-
tectural diagram and a register summary (if applicable). Most chapters within the sections have an introduction, an architec-
tural/application description, register definitions, and timing diagrams. The sections are:
PSoC CY8C20x34 TRM, Version 1.0
Section A:
Pin Information on page
Overview – Presents the PSoC top-level architecture, helpful information to get started, and document history and con-
ventions. The PSoC device pinouts are detailed in the Pin Information chapter.
PSoC Core – Describes the heart of the PSoC device in various chapters, beginning with an architectural overview and a
summary list of registers pertaining to the PSoC core.
CapSense System – Describes the configurable PSoC CapSense system in various chapters, beginning with an archi-
tectural overview and a summary list of registers pertaining to the CapSense system.
System Resources – Presents additional PSoC system resources, beginning with an overview and a summary list of
registers pertaining to system resources.
Registers – Lists all PSoC device registers in register mapping tables, and presents bit-level detail of each PSoC register
in its own Register Reference chapter. Where applicable, detailed register descriptions are located in each chapter.
