These devices are designed to replace multiple traditional MCU-based system components with one, low cost single-chip programmable device. PSoC devices include configurable blocks of analog and digital logic, as well as programmable interconnects. This architecture allows the user to create customized peripheral configurations that 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 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. Configurable global busing allows all the device resources to be combined into a complete custom system. The PSoC automotive CY8C24x23A group can have up to three IO ports that connect to the global digital and analog interconnects, providing access to 4 digital blocks and 6 analog blocks.

The CPU utilizes an interrupt controller with 11 vectors, to simplify programming of real time embedded events. Program execution is timed and protected using the included Sleep and Watch Dog Timers (WDT). Memory includes 4 KB of Flash for program storage and 256 bytes of SRAM for data storage. Program Flash utilizes four protection levels on blocks of 64 bytes, allowing customized software IP protection. The PSoC device incorporates flexible internal clock generators, including a 24 MHz IMO (internal main oscillator) accurate to 4% over temperature and voltage. A low power 32 kHz ILO (internal low speed oscillator) is provided for the Sleep timer and WDT. If crystal accuracy is desired, the ECO (32.768 kHz external crystal oscillator) is available for use as a Real Time Clock (RTC) and can optionally generate a crystal-accurate 24 MHz system clock using a PLL. The clocks, together with programmable clock dividers (as a System Resource), provide the flexibility to integrate almost any timing requirement into the PSoC device. PSoC GPIOs provide connection to the CPU, digital and analog resources of the device. Each pin’s drive mode may be selected from eight options, allowing great flexibility in external interfacing. Every pin also has the capability to generate a system interrupt on high level, low level, and change from last read. 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 (1 available as a System Resource) 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. 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 Characteristics” on page 3. The Analog System The Analog System is composed of 6 configurable blocks, each comprised of an opamp circuit 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 more common PSoC analog functions (most available as user modules) are listed below. ■ 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.

The clocks can be routed to both the digital and analog systems. Additional clocks can be generated using digital PSoC blocks as clock dividers. A multiply accumulate (MAC) provides a fast 8-bit multiplier with 32-bit accumulate, to assist in both general math as well as digital filters. The decimator provides a custom hardware filter for digital signal processing applications including the creation of Delta Sigma ADCs. 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 application of falling voltage levels, while the advanced POR (Power On Reset) circuit eliminates the need for a system supervisor.

Examples of user modules are ADCs, DACs, Amplifiers, and Filters. The device editor also supports easy development of multiple configurations and dynamic reconfiguration. Dynamic configuration 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 out a configuration sheet 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. 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 and 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 the parallel or 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 (12 MHz) operation. Design Browser The Design Browser allows users to select and import preconfigured designs into the user’s project. Users can easily browse a catalog of preconfigured designs to facilitate time-to-design. Examples provided in the tools include a 300-baud modem, LIN Bus master and slave, fan controller, and magnetic card reader. 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. Assembler.

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. Device Editor User Module Selection Placement and Parameter -ization Source Code Generator Generate Application Application Editor Project Manager Source Code Editor Build Manager Build All Debugger Interface to ICE Storage Inspector Event & Breakpoint Manager User Module and Source Code Development Flows 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 assembler 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 downloads 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.
