Cypress Semiconductor Corporation Document Number: 001-52469 Rev. *C * 198 Champion Court * San Jose, CA 95134-1709 * 408-943-2600 Revised July 22, 2009 [+] Feedback CY8C24423A PSoC Functional Overview The PSoC family consists of many programmable system-on-chips with on-chip Controller devices. 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, and programmable interconnects. This architecture enables 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 I/O are included in a range of convenient pinouts and packages. The PSoC architecture, as shown in the Logic Block Diagram on page 1, is comprised of four main areas: PSoC Core, Digital System, Analog System, and System Resources. Configurable global buses allow all the device resources to be combined into a complete custom system. Each CY8C24x23A PSoC device includes four digital blocks and six analog blocks. Depending on the PSoC package, up to 24 general purpose I/O (GPIO) are also included. The GPIO provide access to the global digital and analog interconnects. Digital System The Digital System is composed of four 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 modules. Figure 1. Digital System Block Diagram Port 1 Port 2 Port 0 Digital Clocks From Core To System Bus To Analog System DIGITAL SYSTEM Digital PSoC Block Array Row Input Configuration 8 8 Row 0 DBB00 DBB01 DCB02 4 DCB03 4 8 8 Row Output Configuration PSoC Core The PSoC Core is a powerful engine that supports a rich feature set. The core includes a CPU, memory, clocks, and configurable GPIO (General Purpose I/O). The M8C CPU core is a powerful processor with speeds up to 24 MHz, providing a four MIPS 8-bit Harvard architecture microprocessor. The CPU uses an interrupt controller with multiple vectors, to simplify programming of real time embedded events. Program execution is timed and protected using the included Sleep Timer and Watchdog Timer (WDT). Memory includes 4 KB of Flash for program storage and 256 bytes of SRAM for data storage. Program Flash uses 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 5% 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. GIE[7:0] GIO[7:0] Global Digital Interconnect GOE[7:0] GOO[7:0] Digital peripheral configurations include: PWMs (8 to 32 bit) PWMs with Dead Band (8 to 24 bit) Counters (8 to 32 bit) Timers (8 to 32 bit) Full or Half-Duplex 8-bit UART with selectable parity SPI master and slave I2C master, slave, or multi-master Cyclical Redundancy Checker/Generator (16 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 the optimum choice of system resources for your application. Family resources are shown in Table 1 on page 4. Document Number: 001-52469 Rev. *C Page 2 of 36 [+] Feedback CY8C24423A Analog System The Analog System is composed of six 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 common PSoC analog functions for this device (most available as user modules) are: Figure 2.

Additional resources include a multiplier, decimator, low voltage detection, and power on reset. Brief statements describing the merits of each system resource follow: Getting Started The quickest way to understand PSoC silicon is to read this data sheet and then use the PSoC Designer Integrated Development Environment (IDE). This data sheet is an overview of the PSoC integrated circuit and presents specific pin, register, and electrical specifications. For in depth information, along with detailed programming details, see the PSoC(R) Programmable System-on-Chip Technical Reference Manual for CY8C24x23A PSoC devices. For up-to-date ordering, packaging, and electrical specification information, see the latest PSoC device data sheets on the web at www.cypress.com/psoc. Digital clock dividers provide three customizable clock frequencies 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. 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 0 to 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. An internal 1.3V voltage reference provides an absolute reference for the analog system, including ADCs and DACs.

Document Number: 001-52469 Rev. *C Page 4 of 36 [+] Feedback CY8C24423A Development Tools PSoC Designer is a Microsoft(R) Windows-based, integrated development environment for the Programmable System-on-Chip (PSoC) devices. The PSoC Designer IDE runs on Windows XP or Windows Vista. This system provides design database management by project, an integrated debugger with In-Circuit Emulator, in-system programming support, and built-in support for third-party assemblers and C compilers. PSoC Designer also supports C language compilers developed specifically for the devices in the PSoC family. Code Generation Tools PSoC Designer supports multiple third party C compilers and assemblers. The code generation tools work seamlessly within the PSoC Designer interface and have been tested with a full range of debugging tools. The choice is yours. Assemblers. The assemblers allow assembly code to merge seamlessly with C code. Link libraries automatically use absolute addressing or are compiled in relative mode, and linked with other software modules to get absolute addressing. C Language Compilers. C language compilers are available that support the PSoC family of devices. The products allow you to create complete C programs for the PSoC family devices. The optimizing C compilers provide all the features of C tailored to the PSoC architecture. They come complete with embedded libraries providing port and bus operations, standard keypad and display support, and extended math functionality. Debugger The PSoC Designer Debugger subsystem provides hardware in-circuit emulation, allowing you 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 I/O 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. PSoC Designer Software Subsystems System-Level View A drag-and-drop visual embedded system design environment based on PSoC Express. In the system level view you create a model of your system inputs, outputs, and communication interfaces. You define when and how an output device changes state based upon any or all other system devices. Based upon the design, PSoC Designer automatically selects one or more PSoC On-Chip Controllers that match your system requirements. PSoC Designer generates all embedded code, then compiles and links it into a programming file for a specific PSoC device. Chip-Level View The chip-level view is a more traditional integrated development environment (IDE) based on PSoC Designer 4.4. Choose a base device to work with and then select different onboard analog and digital components called user modules that use the PSoC blocks. Examples of user modules are ADCs, DACs, Amplifiers, and Filters. Configure the user modules for your chosen application and connect them to each other and to the proper pins. Then generate your project. This prepopulates your project with APIs and libraries that you can use to program your application. The device editor also supports easy development of multiple configurations and dynamic reconfiguration. Dynamic configuration allows for changing configurations at run time. Hybrid Designs You can begin in the system-level view, allow it to choose and configure your user modules, routing, and generate code, then switch to the chip-level view to gain complete control over on-chip resources. All views of the project share a common code editor, builder, and common debug, emulation, and programming 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 operates 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. Document Number: 001-52469 Rev. *C Page 5 of 36 [+] Feedback CY8C24423A 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 components 2. Configure components 3. Organize and Connect 4. Generate, Verify, and Debug Organize and Connect You can build signal chains at the chip level by interconnecting user modules to each other and the I/O pins, or connect system level inputs, outputs, and communication interfaces to each other with valuator functions. In the system-level view, selecting a potentiometer driver to control a variable speed fan driver and setting up the valuators to control the fan speed based on input from the pot selects, places, routes, and configures a programmable gain amplifier (PGA) to buffer the input from the potentiometer, an analog to digital converter (ADC) to convert the potentiometer's output to a digital signal, and a PWM to control the fan. In the chip-level view, perform the selection, configuration, and routing so that you have complete control over the use of all on-chip resources. Select Components Both the system-level and chip-level views provide a library of prebuilt, pretested hardware peripheral components. In the system-level view, these components are called "drivers" and correspond to inputs (a thermistor, for example), outputs (a brushless DC fan, for example), communication interfaces (I2C-bus, for example), and the logic to control how they interact with one another (called valuators). In the chip-level view, the components are called "user modules". User modules make selecting and implementing peripheral devices simple, and come in analog, digital, and mixed signal varieties. Generate, Verify, and Debug When you are ready to test the hardware configuration or move on to developing code for the project, perform the "Generate Application" step. This causes PSoC Designer to generate source code that automatically configures the device to your specification and provides the software for the system. Both system-level and chip-level designs generate software based on your design. The chip-level design 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. The system-level design also generates a C main() program that completely controls the chosen application and contains placeholders for custom code at strategic positions allowing you to further refine the software without disrupting the generated code. 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 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. Configure Components Each of the components 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 Pulse Width Modulator (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. Both the system-level drivers and chip-level user modules are documented in data sheets that are viewed directly in the PSoC Designer. These data sheets explain the internal operation of the component and provide performance specifications. Each data sheet describes the use of each user module parameter or driver property, and other information you may need to successfully implement your design.

A Fast-Mode I2C-bus device can be used in a Standard-Mode I2C-bus system, but the requirement TSUDATI2C 250 ns must then be met. This is automatically the case if the device does not stretch the LOW period of the SCL signal. If such device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line trmax + TSUDATI2C = 1000 + 250 = 1250 ns (according to the Standard-Mode I2C-bus specification) before the SCL line is released.
