PSoC® Functional Overview
The PSoC® family consists of many
Mixed-Signal Array with
On-Chip Controller
devices. All PSoC family devices are
designed to replace traditional MCUs, system ICs, and the
numerous discrete components that surround them. The PSoC
CY8C24x94 devices are unique members of the PSoC family
because it includes a full-featured, full-speed (12 Mbps) USB
port. Configurable analog, digital, and interconnect circuitry
enable a high level of integration in a host of industrial, con-
sumer, and communication applications.
This architecture allows the user to create customized periph-
eral configurations that match the requirements of each individ-
ual application. Additionally, a fast CPU, Flash program
memory, SRAM data memory, and configurable IO are included
in a range of convenient 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 including a full-speed USB port. Config-
urable global busing allows all the device resources to be com-
bined into a complete custom system. The PSoC CY8C24x94
devices can have up to seven IO ports that connect to the glo-
bal digital and analog interconnects, providing access to 4 digi-
tal blocks and 6 analog blocks.
