CY8C20236A Designing with PSoC Designer

CY8C20236A  Designing with PSoC Designer
The development process for the PSoC device differs from that
of a traditional fixed function microprocessor. The configurable
analog and digital hardware blocks give the PSoC architecture a
unique flexibility that pays dividends in managing specification
change during development and by lowering inventory costs.
These configurable resources, called PSoC Blocks, have the
ability to implement a wide variety of user-selectable functions.
The PSoC development process can be summarized in the
following four steps:
1. Select User Modules
2. Configure User Modules
3. Organize and Connect
4. Generate, Verify, and Debug
Select Components
PSoC Designer provides a library of pre-built, pre-tested
hardware peripheral components called "user modules." User
modules make selecting and implementing peripheral devices,
both analog and digital, simple.
Configure Components
Each of the User Modules you select establishes the basic
register settings that implement the selected function. They also
provide parameters and properties that allow you to tailor their
precise configuration to your particular application. For example,
a PWM User Module configures one or more
digital PSoC blocks, one for each 8 bits of resolution. The user
module parameters permit you to establish the pulse width and
duty cycle. Configure the parameters and properties to correspond to your chosen application. Enter values directly or by
selecting values from drop-down menus. All the user modules
are documented in datasheets that may be viewed directly in
PSoC Designer or on the Cypress website. These user module
datasheets explain the internal operation of the User Module and
provide performance specifications. Each datasheet describes
the use of each user module parameter, and other information
you may need to successfully implement your design.
Organize and Connect
You build signal chains at the chip level by interconnecting user
modules to each other and the I/O pins. You perform the
selection, configuration, and routing so that you have complete
control over all on-chip resources.
Generate, Verify, and Debug
When you are ready to test the hardware configuration or move
on to developing code for the project, you perform the "Generate
Configuration Files" step. This causes PSoC Designer to
generate source code that automatically configures the device to
your specification and provides the software for the system. The
generated code provides application programming interfaces
(APIs) with high-level functions to control and respond to
hardware events at run time and interrupt service routines that
you can adapt as needed.
A complete code development environment allows you to
develop and customize your applications in C, assembly
language, or both.
The last step in the development process takes place inside
PSoC Designer's Debugger (access by clicking the Connect
icon). PSoC Designer downloads the HEX image to the ICE
where it runs at full speed. PSoC Designer debugging capabilities rival those of systems costing many times more. In addition
to traditional single-step, run-to-breakpoint and watch-variable
features, the debug interface provides a large trace buffer and
allows you to define complex breakpoint events that include
monitoring address and data bus values, memory locations and
external signals.

CY8C20236A Additional System Resources

CY8C20236A Additional System Resources
System resources provide additional capability, such as I
2
C
slave, SPI master, or SPI slave interfaces, three 16-bit
programmable timers, and various system resets supported by
the M8C.
These system resources provide additional capability useful to
complete systems. Additional resources include low voltage
detection and power on reset. The merits of each system
resource are listed here:
■ The I
2
C slave/SPI master-slave module provides 50/100/400
kHz communication over two wires. SPI communication over
three or four wires runs at speeds of 46.9 kHz to 3 MHz (lower
for a slower system clock).
■ The I
2
C hardware address recognition feature reduces the
already low power consumption by eliminating the need for
CPU intervention until a packet addressed to the target device
is received.
■ The I
2
C enhanced slave interface appears as a 32-byte RAM
buffer to the external I
2
C master. Using a simple predefined
protocol, the master controls the read and write pointers into
the RAM. When this method is enabled, the slave does not stall
the bus when receiving data bytes in active mode. For usage
details, refer to the application note I2C Enhanced Slave
Operation - AN56007.
■ Low-voltage detection (LVD) interrupts can signal the
application of falling voltage levels, while the advanced poweron-reset (POR) circuit eliminates the need for a system
supervisor.
■ An internal reference provides an absolute reference for
capacitive sensing.
■ A register-controlled bypass mode allows the user to disable
the LDO regulator.

CY8C20236A CapSense System

CY8C20236A CapSense System
The analog system contains the capacitive sensing hardware.
Several hardware algorithms are supported. This hardware
performs capacitive sensing and scanning without requiring
external components. The analog system is composed of the
CapSense PSoC block and an internal 1 V or 1.2 V analog
reference, which together support capacitive sensing of up to
33 inputs
[2]
. Capacitive sensing is configurable on each GPIO
pin. Scanning of enabled CapSense pins are completed quickly
and easily across multiple ports.
SmartSense?
SmartSense is an innovative solution from Cypress that removes
manual tuning of CapSense applications. This solution is easy to
use and provides a robust noise immunity. It is the only autotuning solution that establishes, monitors, and maintains all
required tuning parameters.  SmartSense allows engineers to go
from prototyping to mass production without re-tuning for
manufacturing variations in PCB and/or overlay material
properties.
Figure 1.  CapSense System Block Diagram
Analog Multiplexer System
The Analog Mux Bus can connect to every GPIO pin. Pins are
connected to the bus individually or in any combination. The bus
also connects to the analog system for analysis with the
CapSense block comparator.
Switch control logic enables selected pins to precharge
continuously under hardware control. This enables capacitive
measurement for applications such as touch sensing. Other
multiplexer applications include:
■ Complex capacitive sensing interfaces, such as sliders and
touchpads.
■ Chip-wide mux that allows analog input from any I/O pin.
■ Crosspoint connection between any I/O pin combinations.

CY8C20236A PSoC? Functional Overview

CY8C20236A PSoC? Functional Overview
The PSoC family consists of on-chip controller devices, which
are designed to replace multiple traditional microcontroller unit
(MCU)-based components with one, low cost single-chip
programmable component. A PSoC device includes
configurable analog and digital blocks, and programmable
interconnect. This architecture allows the user to create
customized peripheral configurations, to match the requirements
of each individual application. Additionally, a fast CPU, Flash
program memory, SRAM data memory, and configurable I/O are
included in a range of convenient pinouts.
The architecture for this device family, as shown in the Logic
Block Diagram on page 2, consists of three main areas:
■ The Core
■ CapSense Analog System
■ System Resources (including a full-speed USB port).
A common, versatile bus allows connection between I/O and the
analog system.
Each CY8C20x36A/66A PSoC device includes a dedicated
CapSense block that provides sensing and scanning control
circuitry for capacitive sensing applications. Depending on the
PSoC package, up to 36 GPIO are also included. The GPIO
provides access to the MCU and analog mux.
PSoC Core
The PSoC Core is a powerful engine that supports a rich
instruction set. It encompasses SRAM for data storage, an
interrupt controller, sleep and watchdog timers, and IMO and
ILO. The CPU core, called the M8C, is a powerful processor with
speeds up to 24 MHz. The M8C is a 4-MIPS,
8-bit Harvard-architecture microprocessor.

CY7C0832BV-133AI Code Extract

CY7C0832BV-133AI Code Extract, cypress MCU decryption, cypress chip crack, cypress PCB clone .
The FLEx18? family includes 2-Mbit, 4-Mbit, and 9-Mbit
pipelined, synchronous, true dual port static RAMs that are high
speed, low power 3.3 V CMOS. Two ports are provided,
permitting independent, simultaneous access to any location in
memory. The result of writing to the same location by more than
one port at the same time is undefined. Registers on control,
address, and data lines allow for minimal setup and hold time.
During a Read operation, data is registered for decreased cycle
time. Each port contains a burst counter on the input address
register. After externally loading the counter with the initial
address, the counter increments the address internally (more
details to follow). The internal Write pulse width is independent
of the duration of the R/W input signal. The internal Write pulse
is self-timed to allow the shortest possible cycle times.
A HIGH on CE0
 or LOW on CE1
 for one clock cycle powers down
the internal circuitry to reduce the static power consumption. One
cycle with chip enables asserted  is required to reactivate the
outputs.
Additional features include: readback of burst-counter internal
address value on address lines, counter-mask registers to
control the counter wrap around, counter interrupt (CNTINT)
flags, readback of mask register value on address lines,
retransmit functionality, interrupt flags for  message passing,
JTAG for boundary scan, and asynchronous Master Reset
(MRST).
The CY7C0833V device in this family has limited features. See
Address Counter and Mask Register Operations on page 7 for
details.
