PSoC® Mixed-Signal Array Final Data Sheet
CY8C27143, CY8C27243,
CY8C27443, CY8C27543, and CY8C27643
PSoC® Functional Overview
The PSoC® family consists of many Mixed-Signal Array with
On-Chip Controller devices. These devices are designed to
replace multiple traditional MCU-based system components
with one, low cost single-chip programmable device. PSoC
devices include configurable blocks of analog and digital logic,
as well as programmable interconnects. This architecture
allows the user to create customized peripheral configurations
that match the requirements of each individual application.
Additionally, a fast CPU, Flash program memory, SRAM data
memory, and configurable IO are included in a range of conve-
nient pinouts and packages.
The PSoC architecture, as illustrated on the left, is comprised of
four main areas: PSoC Core, Digital System, Analog System,
and System Resources. Configurable global busing allows all
the device resources to be combined into a complete custom
system. The PSoC CY8C27x43 family can have up to five IO
ports that connect to the global digital and analog interconnects,
providing access to 8 digital blocks and 12 analog blocks.
The PSoC Core
The PSoC Core is a powerful engine that supports a rich fea-
ture set. The core includes a CPU, memory, clocks, and config-
urable GPIO (General Purpose IO).
The M8C CPU core is a powerful processor with speeds up to
24 MHz, providing a four MIPS 8-bit Harvard architecture micro-
