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 component. A PSoC device includes configurable blocks of analog and digital logic, as well as programmable interconnect. This architecture allows the user to create customized peripheral configuration s, to 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 convenient pinouts.
The PSoC architecture, as illustrated on the left, is comprised of four main areas: the Core, the System Resources, the Digital System, and the Analog System. Configurable global bus resources allow all the device resources to be combined into a complete custom system. Each CY8C21x34 PSoC device includes four digital blocks and four analog blocks. Depending on the PSoC package, up to 28 general purpose IO (GPIO) are also included. The GPIO provide access to the global digital and analog interconnects.
The 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 (inter­nal main oscillator) and ILO (internal low speed oscillator). The

CY8C21x34 Final Data Sheet PSoC® Overview
CPU core, called the M8C, is a powerful processor with speeds up to 24 MHz. The M8C is a four MIPS 8-bit Harvard architec­ture microprocessor.
System Resources provide additional capability, such as digital clocks to increase the flexibility of the PSoC mixed-signal arrays, I2C functionality for implementing an I2C master, slave, MultiMaster, an internal voltage reference that provides an absolute value of 1.3V to a number of PSoC subsystems, a switch mode pump (SMP) that generates normal operating volt­ages off a single battery cell, and various system resets sup­ported by the M8C.
The Digital System is composed of an array of digital PSoC blocks, which can be configured into any number of digital peripherals. The digital blocks can be connected to the GPIO through a series of global buses that can route any signal to any pin. Freeing designs from the constraints of a fixed peripheral controller.
The Analog System is composed of four analog PSoC blocks, supporting comparators and analog-to-digital conversion up to 8 bits in precision.
The Digital System
The Digital System is composed of 4 digital PSoC blocks. Each block is an 8-bit resource that can be used alone or combined with other blocks to form 8, 16, 24, and 32-bit peripherals, which are called user module references. Digital peripheral configura­tions include those listed below.
PWMs (8 to 32 bit)
PWMs with Dead band (8 to 32 bit)
Counters (8 to 32 bit)
Timers (8 to 32 bit)
UART 8 bit with selectable parity
SPI master and slave
I2C slave and multi-master
Cyclical Redundancy Checker/Generator (8 to 32 bit)
IrDA
Pseudo Random Sequence Generators (8 to 32 bit)
The digital blocks can be connected to any GPIO through a series of global buses that can route any signal to any pin. The buses also allow for signal multiplexing and for performing logic operations. This configurability frees your designs from the con­straints of a fixed peripheral controller.

The Analog System
The Analog System is composed of 4 configurable blocks, allowing the creation of complex analog signal flows. Analog peripherals are very flexible and can be customized to support specific application requirements. Some of the common PSoC analog functions for this device (most available as user mod­ules) are listed below.
Analog-to-digital converters (single or dual, with 8-bit resolu-
tion)
Pin-to-pin comparator
Single-ended comparators (up to 2) with absolute (1.3V) ref-
erence or 8-bit DAC reference
1.3V reference (as a System Resource)
In most PSoC devices, analog blocks are provided in columns of three, which includes one CT (Continuous Time) and two SC (Switched Capacitor) blocks. The CY8C21x34 devices provide limited functionality Type “E” analog blocks. Each column con­tains one CT Type E block and one SC Type E block. Refer to the PSoC Mixed-Signal Array Technical Reference Manual for detailed information on the CY8C21x34’s Type E analog blocks.
Digital blocks are provided in rows of four, where the number of blocks varies by PSoC device family. This allows you the opti­mum choice of system resources for your application. Family resources are shown in the table titled “PSoC Device Charac-
teristics” on page 3.

The Analog Multiplexer System
The Analog Mux Bus can connect to every GPIO pin. Pins can be connected to the bus individually or in any combination. The bus also connects to the analog system for analysis with com­parators and analog-to-digital converters. An additional 8:1 ana­log input multiplexer provides a second path to bring Port 0 pins to the analog array.
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:
Track pad, finger sensing.
Chip-wide mux that allows analog input from any IO pin.
Crosspoint connection between any IO pin combinations.
When designing capacitive sensing applications, refer to the signal-to-noise system level requirement found in Application Note AN2403 at http://www.cypress.com/design/AN2403 on the Cypress web site.
Additional System Resources
System Resources, some of which have been previously listed, provide additional capability useful to complete systems. Addi­tional resources include a switch mode pump, low voltage detection, and power on reset. Brief statements describing the merits of each system resource are presented below.
Digital clock dividers provide three customizable clock fre-
quencies for use in applications. The clocks can be routed to both the digital and analog systems. Additional clocks can be generated using digital PSoC blocks as clock dividers.
The I2C module provides 100 and 400 kHz communication
over two wires. Slave, master, and multi-master modes are all supported.
Low Voltage Detection (LVD) interrupts can signal the appli-
cation of falling voltage levels, while the advanced POR (Power On Reset) circuit eliminates the need for a system supervisor.
An internal 1.3 voltage reference provides an absolute refer-
ence for the analog system, including ADCs and DACs.
An integrated switch mode pump (SMP) generates normal
operating voltages from a single 1.2V battery cell, providing a low cost boost converter.
Versatile analog multiplexer system.

CY8C21x34 Final Data Sheet PSoC® Overview
PSoC Designer Software Subsystems
Device Editor
The device editor subsystem allows the user to select different onboard analog and digital components called user modules using the PSoC blocks. Examples of user modules are ADCs, DACs, Amplifiers, and Filters.
The device editor also supports easy development of multiple configurations and dynamic reconfiguration. Dynamic reconfig­uration allows for changing configurations at run time.
PSoC Designer sets up power-on initialization tables for selected PSoC block configurations and creates source code for an application framework. The framework contains software to operate the selected components and, if the project uses more than one operating configuration, contains routines to switch between different sets of PSoC block configurations at run time. PSoC Designer can print o ut a con figuration sh eet for a given project configuration for use during application pro­gramming in conjunction with the Device Data Sheet. Once the framework is generated, the user can add application-specific code to flesh out the framework. It’s also possible to change the selected components and regenerate the framework.
Design Browser
Application Editor
In the Application Editor you can edit your C language and Assembly language source code. You can also assemble, com­pile, link, and build.
Debugger
The PSoC Designer Debugger subsystem provides hardware in-circuit emulation, allowing the designer to test the program in a physical system while providing an internal view of the PSoC device. Debugger commands allow the designer to read the program and read and write data memory, read and write IO registers, read and write CPU registers, set and clear break­points, and provide program run, halt, and step control. The debugger also allows the designer to create a trace buffer of registers and memory locations of interest.
Online Help System
The online help system displays online, context-sensitive help for the user. Designed for procedural and quick reference, each functional subsystem has its own context-sensitive help. This system also provides tutorials and links to FAQs and an Online Support Forum to aid the designer in getting started.
Hardware Tools
In-Circuit Emulator
A low cost, high functionality ICE (In-Circuit Emulator) is avail­able for development support. This hardware has the capability to program single devices.
The emulator consists of a base unit that connects to the PC by way of a USB port. The base unit is universal and will operate with all PSoC devices. Emulation pods for each device family are available separately. The emulation pod takes the place of the PSoC device in the target board and performs full speed (24 MHz) operation.
Assembler. The macro assembler allows the assembly code to be merged seamlessly with C code. The link libraries auto­matically use absolute addressing or can be compiled in relative mode, and linked with other software modules to get absolute addressing.
C Language Compiler. A C language compiler is available that supports the PSoC family of devices. Even if you have never worked in the C language before, the product quickly allows you to create complete C programs for the PSoC family devices.
The embedded, optimizing C compiler provides all the features of C tailored to the PSoC architecture. It comes complete with embedded libraries providing port and bus operations, standard keypad and display support, and extended math functionality.

CY8C21x34 Final Data Sheet PSoC® Overview

Designing with User Modules

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. Each block has several registers that determine its function and connectivity to other blocks, multiplexers, buses and to the IO pins. Iterative development cycles permit you to adapt the hard­ware as well as the software. This substantially lowers the risk of having to select a different part to meet the final design requirements.
To speed the development process, the PSoC Designer Inte­grated Development Environment (IDE) provides a library of pre-built, pre-tested hardware peripheral functions, called “User Modules.” User modules make selecting and implementing peripheral devices simple, and come in analog, digital, and mixed signal varieties. The standard User Module library con­tains over 50 common peripherals such as ADCs, DACs Tim­ers, Counters, UARTs, and other not-so common peripherals such as DTMF Generators and Bi-Quad analog filter sections.
Each user module establishes the basic register settings that implement the selected function. It also provides parameters that allow you to tailor its precise configuration to your particular application. For example, a Pulse Width Modulator 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. User modules also provide tested software to cut your development time. The user module application programming interface (API) provides high­level functions to control and respond to hardware events at run time. The API also provides optional interrupt service routines that you can adapt as needed.
The API functions are documented in user module data sheets that are viewed directly in the PSoC Designer IDE. These data sheets explain the internal operation of the user module and provide performance specifications. Each data sheet describes the use of each user module parameter and documents the set­ting of each register controlled by the user module.
The development process starts when you open a new project and bring up the Device Editor, a graphical user interface (GUI) for configuring the hardware. You pick the user modules you need for your project and map them onto the PSoC blocks with point-and-click simplicity. Next, you build signal chains by inter­connecting user modules to each other and the IO pins. At this stage, you also configure the clock source connections and enter parameter values directly or by selecting values from drop-down menus. When you are ready to test the hardware configuration or move on to developing code for the project, you perform the “Generate Application” step. This causes PSoC Designer to generate source code that automatically configures the device to your specification and provides the high-level user module API functions.

The next step is to write your main program, and any sub-rou­tines using PSoC Designer’s Application Editor subsystem. The Application Editor includes a Project Manager that allows you to open the project source code files (including all gener­ated code files) from a hierarchal view. The source code editor provides syntax coloring and advanced edit features for both C and assembly language. File search capabilities include simple string searches and recursive “grep-style” patterns. A single mouse click invokes the Build Manager. It employs a profes­sional-strength “makefile” system to automatically analyze all file dependencies and run the compiler and asse mbler as nec­essary. Project-level options control optimization strategies used by the compiler and linker. Syntax errors are displayed in a console window. Double clicking the error message takes you directly to the offending line of source code. When all is correct, the linker builds a HEX file image suitable for programming.
The last step in the development process takes place inside the PSoC Designer’s Debugger subsystem. The Debugger d own­loads the HEX image to the In-Circuit Emulator (ICE) where it runs at full speed. Debugger capabilities rival those of systems costing many times more. In addition to traditional single-step, run-to-breakpoint and watch-variable features, the Debugger provides a large trace buffer and allows you define complex breakpoint events that include monitoring address and data bus values, memory locations and external signals.
