6.4.15 Over Voltage Tolerance
All I/O pins provide an over voltage tolerance feature at any
operating V
A common application for this feature is connection to a bus such
as I
voltages. In the I
Open Drain, Drives Low mode for the SIO pin. This allows an
external pull-up to pull the I
supply. For example, the PSoC chip could operate at 1.8 V, and
an external device could run from 5 V. Note that the SIO pin’s V
and V
pin.
The I/O pin must be configured into a high impedance drive
mode, open drain low drive mode, or pull-down drive mode, for
over voltage tolerance to work properly. Absolute maximum
ratings for the device must be observed for all I/O pins.
6.4.16 Reset Configuration
While reset is active all I/Os are reset to and held in the High
Impedance Analog state. After reset is released, the state can be
reprogrammed on a port-by-port basis to pull-down or pull-up. To
ensure correct reset operation, the port reset configuration data
is stored in special nonvolatile registers. The stored reset data is
automatically transferred to the port reset configuration registers
at reset release.
6.4.17 Low-Power Functionality
In all low-power modes the I/O pins retain their state until the part
is awakened and changed or reset. To awaken the part, use a
pin interrupt, because the port interrupt logic continues to
function in all low-power modes.
6.4.18 Special Pin Functionality
Some pins on the device include additional special functionality
in addition to their GPIO or SIO functionality. The specific special
function pins are listed in
are:
Document Number: 001-53413 Rev. *J
There are no current limitations for the SIO pins as they present a
high impedance load to the external circuit where Vddio < V
5.5 V.
The GPIO pins must be limited to 100 µA using a current limiting
resistor. GPIO pins clamp the pin voltage to approximately one
diode above the Vddio supply where Vddio < V
In case of a GPIO pin configured for analog input/output, the
analog voltage on the pin must not exceed the Vddio supply
voltage to which the GPIO belongs.

6.4.19 JTAG Boundary Scan
The device supports standard JTAG boundary scan chains on all
I/O pins for board level test.
7. Digital Subsystem
The digital programmable system creates application specific
combinations of both standard and advanced digital peripherals
and custom logic functions. These peripherals and logic are then
interconnected to each other and to any pin on the device,
providing a high level of design flexibility and IP security.
The features of the digital programmable system are outlined
here to provide an overview of capabilities and architecture. You
do not need to interact directly with the programmable digital
system at the hardware and register level. PSoC Creator
provides a high level schematic capture graphical interface to
automatically place and route resources similar to PLDs.
The main components of the digital programmable system are:
Figure 7-1. CY8C36 Digital Programmable Architecture
Universal Digital Blocks (UDB) – These form the core
functionality of the digital programmable system. UDBs are a
collection of uncommitted logic (PLD) and structural logic
(Datapath) optimized to create all common embedded
peripherals and customized functionality that are application or
design specific.
Universal Digital Block Array – UDB blocks are arrayed within
a matrix of programmable interconnect. The UDB array
structure is homogeneous and allows for flexible mapping of
digital functions onto the array. The array supports extensive
and flexible routing interconnects between UDBs and the
Digital System Interconnect.
Digital System Interconnect (DSI) – Digital signals from
Universal Digital Blocks (UDBs), fixed function peripherals, I/O
pins, interrupts, DMA, and other system core signals are
attached to the Digital System Interconnect to implement full
featured device connectivity. The DSI allows any digital function
to any pin or other feature routability when used with the
Universal Digital Block Array.
