Introduction
PSoC 4 is a true programmable embedded system-on-chip, integrating custom analog and digital peripheral
functions, memory, and an ARM Cortex-M0 or Cortex-M0+ microcontroller on a single chip.
This type of system is different from most mixed-signal embedded systems, which use a combination of a
microcontroller unit (MCU) and external analog and digital peripherals. Such systems typically require many
integrated circuits in addition to the MCU, such as opamps, ADCs, and (ASICs).
PSoC 4 provides a low-cost alternative to the combination of MCU and external ICs. In addition to reducing overall
system cost, the programmable analog and digital subsystems allow great flexibility, in-field tuning of the design, and
speedy time to market.
®
The capacitive touch-sensing feature in PSoC 4, known as CapSense , offers unprecedented signal-to-noise ratio;
best-in-class waterproofing; and a wide variety of sensor types such as buttons, sliders, track pads, and proximity
sensors.
PSoC 4 offers a best-in-class current consumption of 150 nA while retaining SRAM, programmable logic, and the
ability to wake up from an interrupt. PSoC 4 consumes only 20 nA while maintaining wakeup capability in its nonretention power mode.
The PSoC 4 family of devices also contains PSoC 4 BLE, which integrates a Bluetooth Low Energy (BLE) radio
system. For more details on PSoC 4 BLE, see AN91267.

PSoC is More Than an MCU
Figure 5 shows that a typical MCU contains a CPU (such as 8051 or an ARM Cortex) with a set of peripheral
functions such as ADCs, DACs, UARTs, SPIs, and general I/O, all linked to the CPU’s register interface. Within the
MCU, the CPU is the “heart” of the device – the CPU manages everything from setup to data movement to timing.
Without the CPU, the MCU cannot function.
Figure 6 shows that PSoC is quite different. With PSoC, the CPU, analog, digital, and I/O are equally important
resources in a programmable system. It is the system’s interconnect and programmability that is the heart of PSoC –
not the CPU. The peripheral analog and digital are interconnected with a highly configurable matrix of signal and data
bus meshing that allows you to create custom designs that meet your application requirements. You can program
PSoC to emulate an MCU, but you cannot program an MCU to emulate PSoC.

A typical MCU requires CPU firmware to process state machines, use a timer for timing, and drive an output pin.
Thus, the functional path is almost always through the CPU. However, with PSoC, asynchronous parallel processing
is possible. You can configure a PSoC to have elements that operate independently from the CPU. The projects
included with this application note demonstrate this concept. The PSoC is configured to make an LED blink without
writing any code for the CPU.
4.1
The Concept of PSoC Creator Components
One other important thing about PSoC is the availability of PSoC Creator IDE. In PSoC Creator, different PSoC
resources are organized as graphical elements called Components which can be dragged and dropped on to a
schematic to quickly build designs. Every peripheral in PSoC is available as a pre-validated PSoC Creator
Component – PWM Component, ADC Component, DAC Component, CapSense Component, UART Component and
so on. The availability of pre-validated Components in the PSoC Creator significantly reduces the development time.
It also allows you to quickly make changes in the design using graphical options.
For example, configuring a PWM to blink an LED in a typical microcontroller involves the following:
1.
Locate the registers corresponding to the PWM block.
2.
Calculate the values to be written to the PWM registers based on the required PWM period and duty cycle.
3.
Write many lines of code to configure the PWM registers, set the pin drive mode and to connect the PWM output
to the pin. Many MCUs do not offer alternate pins to connect to the internal blocks.
To implement the same functionality in PSoC is a trivial exercise as you will find out later in this application note.
Later, if you need to reconfigure the same PWM block to a Timer, you do not need anything more than a few mouse
clicks in PSoC Creator!
The PSoC also has programmable digital blocks known as Universal Digital Blocks (UDBs). PSoC Creator also
provides several Components made out of UDBs like UART, SPI, I2S, Timer, PWM, Counter, Digital Gates (AND,
OR, NOT, XOR etc), and many more. You can even create your own custom state machines and digital logic using
the UDBs in PSoC Creator. The method to create your own custom PSoC Creator Components is provided in the

About the Design
This design simply blinks two LEDs using a TCPWM Component, as shown in Figure 7. The TCPWM is configured in
PWM mode. The two complementary outputs of this PWM control the LEDs. The PWM operates at a very low
frequency and 50 percent duty cycle so that the toggling of the LEDs is visible. If you use a dual-color LED instead of
two separate LEDs, this project can toggle the color of the dual-color LED.

A PWM Component requires an input clock for its operation. Drag and drop a Clock Component onto the
schematic, and configure the Frequency to 800 Hz by double-clicking on the Component, as shown in Figure 14
and Figure 15.
Since the Prescaler value set in PWM Component is 8, the effective input clock of the PWM is only 100 Hz.
Therefore, the PWM period of 254 results in a PWM output time period of 2.54 seconds.

Function
*PSoC 4000 parts have fixed pins for complementary PWM outputs – P1[1] and P1[6]. You cannot use any other pins
for PWM outputs. Refer to the device datasheet for more details. If you are using the CY8CKIT-040, you can use the
green LED connected to P1[1], as LED1. To use the red LED as LED2, connect P3[2] from header J4 to P1[6] from
header J3, using a wire. Alternately, you can connect an external LED to P1[6] as LED2.
**Similar to the note above, If you are using the CY8CKIT-041, you can use the green LED connected to P2[6], as
LED1 and the complementary PWM output P2[7] for LED2. To use the red LED as LED2, connect P3[4] from header
J2 to P2[7] from header J3, using a wire. Alternately, you can connect an external LED to P2[7] as LED2.
Note: CY8CKIT-043 and CY8CKIT-049 have only one LED connected to P1[6]. If you are using CY8CKIT-049, you
can connect an external LED to pin P0[2].

CPU – ARM Cortex M0 / Cortex M0+
®
The PSoC 4 ARM Cortex-M0 core is a 32-bit CPU optimized for low-power operation. It has an efficient three-stage
pipeline, a fixed 4-GB memory map, and supports the ARMv6-M Thumb instruction set. The Cortex-M0 also features
a single-cycle 32- bit multiply instruction and low-latency interrupt handling. Other subsystems tightly linked to the
CPU core include a nested vectored interrupt controller (NVIC), a SYSTICK timer, and debug. The ARM Cortex-M0+
which is available on PSoC 4000S and PSoC 4100S is an optimized superset of the Cortex-M0 with a core pipeline of
just two stages resulting in better power efficiency.

The PSoC 4 system resources consist of the power system, clock system, reset, and voltage reference. The power
system provides assurance that voltage levels are as required for each respective mode and either delay mode entry
(on power-on reset (POR), for example) until voltage levels are as required for proper function or generate resets
(brown-out detect (BOD)) or interrupts (low voltage detect (LVD)).
The PSoC 4 clock system is responsible for providing clocks to all subsystems that require clocks and for switching
between different clock sources without glitching. In addition, the clock system ensures that no meta-stable conditions
occur. The clock system for the PSoC 4200L consists of a Watch Crystal Oscillator (WCO) running at 32 kHz, the
IMO (3 to 48 MHz) and the ILO (32-kHz nominal) internal oscillators, and provision for an external clock. Refer to the
device datasheet of the respective PSoC 4 device for the exact clock resources available on the chip.

5.7.10 UDB
Universal Digital Blocks (UDBs) are programmable digital blocks that can be used to create custom digital logic apart
from the resources that are already present in PSoC. PSoC Creator provides Components for PWM, Counter, UART,
SPI, I2S and many other commonly used digital blocks which are made out of UDBs.
Apart from these, the UDBs can also be used to create a state machine or a custom communication protocol. They
can also be used to add logic gates to your design like OR, AND, XOR etc.
The PSoC 4 has up to eight UDBs; the UDB array also provides a switched Digital System Interconnect (DSI) fabric
that allows signals from peripherals and ports to be routed to and through the UDBs for communication and control.

interposed between a GPIO port and the connections to it from various peripherals and sources. Smart IO is a fabric
of switches and LUTs that allows Boolean functions to be performed on signals being routed to the pins of a GPIO
port. The Smart IO Component should be used whenever simple logic operations and routing are required to be
performed on signals going to and coming from I/O pins. Each Smart IO Component is associated with a particular
GPIO port and consumes the port entirely. If the Component is not used, then the Smart IO functionality for that port
is bypassed.

Summary
This application note explored the PSoC 4 architecture and development tools. PSoC 4 is a truly programmable
embedded system-on-chip, integrating configurable analog and digital peripheral functions, memory, and an ARM
Cortex-M0/M0+ microcontroller on a single chip. Because of the integrated features and low-leakage power modes,
PSoC 4 is an ideal choice for low-power and cost-effective embedded systems.
This application note also guided you to a comprehensive collection of resources to accelerate in-depth learning
about PSoC 4.
