many devices with on-chip controllers. These devices are designed to replace multiple traditional microcontroller unit (MCU)-based system components with one, low-cost single-chip programmable component. A PSoC device includes configurable blocks of analog and digital logic, and programmable interconnect. This architecture makes it possible for you 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 PSoC architecture, as illustrated in the “Logic Block Diagram” on page 1, comprises 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 24 GPIOs are also included. The GPIOs 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 an internal main oscillator (IMO) and internal low-speed oscillator (ILO). The CPU core, called the M8C, is a powerful processor with speeds up to 24 MHz. The M8C is a four-million instructions per second (MIPS) 8-bit Harvard-architecture microprocessor. which are called user modules. Digital peripheral configurations include those listed. ■ 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 (implemented in a dedicated I2C block) ■ Cyclical redundancy checker/generator (16-bit) ■ Infrared Data Association (IrDA) ■ PRS 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. Figure 1. Digital System Block Diagram Port 3 Port 1 Port 2 Digital Clocks From Core System Resources provide additional capability, such as digital clocks for increased flexibility, I2C functionality for implementing an I2C master, slave, or multi-master, an internal voltage reference that provides an absolute value of 1.3 V to a number of PSoC subsystems, and various system resets supported by the M8C. The Analog System is composed of four analog PSoC blocks, supporting comparators and analog-to-digital conversion with up to 10 bits of precision. The 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, Document Number: 001-12550 Rev. *J To Analog System To System Bus DIGITAL SYSTEM Row Input Configuration Digital PSoC Block Array Row 0 DBB00 DBB01 DCB02 4 Row Output Configuration 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. This frees designs from the constraints of a fixed peripheral controller. Port 0 DCB03 4 8 8 8 8 GIE[7:0] GIO[7:0] Global Digital Interconnect GOE[7:0] GOO[7:0] 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 Table 1 on page 5. Page 3 of 39 CY8C21334, CY8C21534 The Analog System The Analog System is composed of four 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. ■ ADCs (single or dual, with up to 10-bit resolution) ■ Pin-to-pin comparator ■ Single-ended comparators (up to two) with absolute (1.3 V) reference or 8-bit DAC reference ■ 1.3 V reference (as a system resource) In most PSoC devices, analog blocks are provided in columns of three, which includes one continuous time (CT) and two switched capacitor (SC) 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 Programmable System-on-Chip Technical Reference Manual for detailed information on the CY8C21x34’s Type E analog blocks. Figure 2. Analog System Block Diagram From Port 0 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 ADCs. 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 I/O pin. ■ Crosspoint connection between any I/O pin combination. Additional System Resources System resources, some of which have been previously listed, provide additional capability useful for complete systems. Brief statements describing the merits of each system resource are presented. ■ 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. ■ The I2C module provides communication up to 400 kHz over two wires. Slave, master, and multi-master modes are all supported. ■ LVD interrupts can signal the application of falling voltage levels, while the advanced power-on reset (POR) circuit eliminates the need for a system supervisor. ■ An internal 1.3 V voltage reference provides an absolute reference for the analog system, including ADCs and DACs. ■ Versatile analog multiplexer system.

Document Number: 001-12550 Rev. *J Page 5 of 39 CY8C21334, CY8C21534 Development Tools PSoC Designer™ is the revolutionary integrated design environment (IDE) that you can use to customize PSoC to meet your specific application requirements. PSoC Designer software accelerates system design and time to market. Develop your applications using a library of precharacterized analog and digital peripherals (called user modules) in a drag-and-drop design environment. Then, customize your design by leveraging the dynamically generated application programming interface (API) libraries of code. Finally, debug and test your designs with the integrated debug environment, including in-circuit emulation and standard software debug features. PSoC Designer includes: ■ Application editor graphical user interface (GUI) for device and user module configuration and dynamic reconfiguration ■ Extensive user module catalog ■ Integrated source-code editor (C and assembly) ■ Free C compiler with no size restrictions or time limits ■ Built-in debugger ■ In-circuit emulation ■ Built-in support for communication interfaces: 2 ❐ Hardware and software I C slaves and masters ❐ Full-speed USB 2.0 ❐ Up to four full-duplex universal asynchronous receiver/transmitters (UARTs), SPI master and slave, and wireless PSoC Designer supports the entire library of PSoC 1 devices and runs on Windows XP, Windows Vista, and Windows 7. PSoC Designer Software Subsystems Design Entry In the chip-level view, choose a base device to work with. Then select different onboard analog and digital components that use the PSoC blocks, which are called user modules. 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 tool also supports easy development of multiple configurations and dynamic reconfiguration. Dynamic reconfiguration makes it possible to change configurations at run time. In essence, this allows you to use more than 100 percent of PSoC's resources for an application. Document Number: 001-12550 Rev. *J Code Generation Tools The code generation tools work seamlessly within the PSoC Designer interface and have been tested with a full range of debugging tools. You can develop your design in C, assembly, or a combination of the two. Assemblers. The assemblers allow you to merge assembly code seamlessly with C code. Link libraries automatically use absolute addressing or are compiled in relative mode, and are 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 of 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 PSoC Designer has a debug environment that 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 you to read and program and read and write data memory, and read and write I/O registers. You can read and write CPU registers, set and clear breakpoints, and provide program run, halt, and step control. The debugger also allows you to create a trace buffer of registers and memory locations of interest. Online Help System The online help system displays online, context-sensitive help. 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-Circuit Emulator A low-cost, high-functionality in-circuit emulator (ICE) is available for development support. This hardware can program single devices. The emulator consists of a base unit that connects to the PC using 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. Page 6 of 39 CY8C21334, CY8C21534 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. Organize and Connect 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 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. 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. Document Number: 001-12550 Rev. *J 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 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.

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.

Or when devices are cascaded in width, the slave device is the one that allows another device to control the timing of data exchanges between the cascaded devices and an external interface. The controlling device is called the master device. SRAM An acronym for static random access memory. A memory device where you can store and retrieve data at a high rate of speed. The term static is used because, after a value is loaded into an SRAM cell, it remains unchanged until it is explicitly altered or until power is removed from the device. SROM An acronym for supervisory read only memory. The SROM holds code that is used to boot the device, calibrate circuitry, and perform flash operations. The functions of the SROM may be accessed in normal user code, operating from flash. stop bit A signal following a character or block that prepares the receiving device to receive the next character or block. synchronous 1. A signal whose data is not acknowledged or acted upon until the next active edge of a clock signal. 2. A system whose operation is synchronized by a clock signal. tri-state A function whose output can adopt three states: 0, 1, and Z (high-impedance). The function does not drive any value in the Z state and, in many respects, may be considered to be disconnected from the rest of the circuit, allowing another output to drive the same net. UART A UART or universal asynchronous receiver-transmitter translates between parallel bits of data and serial bits. user modules Pre-built, pre-tested hardware/firmware peripheral functions that take care of managing and configuring the lower level analog and digital PSoC blocks. User modules also provide high level API (Application Programming Interface) for the peripheral function. user space The bank 0 space of the register map.
