A TrueTouch device includes the configurable TrueTouch block, configurable analog and digital logic, programmable interconnect, and an 8-bit CPU to run custom firmware. This architecture enables the user to create flexible, customized single-touch touchscreen configurations to match the requirements of each individual touchscreen application. Various configurations of Flash program memory, SRAM data memory, and configurable IO are included in a range of convenient pinouts. The TrueTouch architecture is comprised of four main areas: the Core, Digital System, the TrueTouch Analog System, and System Resources including a full speed USB port. Configurable global busing allows all the device resources to be combined into a complete custom touchscreen system. The CY8CTST120 device can have up to seven IO ports that connect to the global digital and analog interconnects, providing access to four digital blocks and six analog blocks. Implementation of touchscreen applications allows additional digital and analog resources to be used depending on the touchscreen design. The CY8CTST120 is offered in a 56-pin QFN package with up to 48 general purpose IO (GPIO), and support of up to 44 X/Y sensors. When designing touchscreen applications, refer to the UM data sheet for performance requirements to meet and detailed design process explanation. from eight options, allowing great flexibility in external interfacing. Every pin is capable of generating a system interrupt on high level, low level, and change from last read. The Digital System The Digital System is composed of four digital PSoC blocks. Each block is an 8-bit resource that is used alone or combined with other blocks to form 8, 16, 24, and 32-bit peripherals, which are called user module references. Figure 1.

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 up to 20 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 encompasses 16K of Flash for program storage, 1K of SRAM for data storage, and up to 2K of EEPROM emulated using the Flash. Program Flash uses four protection levels on blocks of 64 bytes, allowing customized software IP protection. The TrueTouch device incorporates flexible internal clock generators, including a 24 MHz IMO (internal main oscillator) accurate to 8% over temperature and voltage. The 24 MHz IMO can also be doubled to 48 MHz for use by the digital system. A low power 32 kHz ILO (internal low speed oscillator) is provided for the sleep timer and WDT. The clocks, together with programmable clock dividers (as a System Resource), provide the flexibility to integrate almost any timing requirement into the TrueTouch device. In USB systems, the IMO self-tunes to 0.25% accuracy for USB communication. The GPIOs provide connection to the CPU, digital and analog resources of the device. Each pin's drive mode may be selected Digital peripheral configurations include those listed below. Full-Speed USB (12 Mbps) PWMs (8 to 32 bit) PWMs with dead band (8 to 24 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 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 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 characteristics are shown in Table 1 on page 4. Document Number: 001-46932 Rev. *B Page 2 of 32 [+] Feedback CY8CTST120 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. Analog-to-digital converters (up to 2, with 6 to 14-bit resolution, selectable as Incremental, Delta Sigma, and SAR) Figure 2.

The Analog Multiplexer System The Analog Mux Bus connects to every GPIO pin in ports 0-5. Pins are connected to the bus individually or in any combination. The bus also connects to the analog system for capacitive sensing with the TrueTouch block comparator. It can be split into two sections for simultaneous dual-channel processing. 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 switch dynamically under hardware control. This enables capacitive measurement for the touchscreen application. Other multiplexer applications include: ASD20 AnalogReference Interface to Digital System RefHi RefLo AGND Reference Generators AGNDIn RefIn Bandgap M8C Interface (Address Bus, Data Bus, Etc.)

Manufacturing Information File Emulation Pod In-Circuit Emulator Device Programmer 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 configuration allows 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. If the project uses more than one operating configuration, it contains routines to switch between different sets of PSoC block configurations at run time. PSoC Designer prints out a configuration sheet for a given project configuration for use during application programming in conjunction with the device data sheet. After 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 The Design Browser allows users to select and import preconfigured designs into the project. Users can easily browse a catalog of preconfigured designs to facilitate time-to-design. Document Number: 001-46932 Rev. *B 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 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. TrueTouch Touchscreen Tuner The TrueTouch tuner is a Microsoft(R) Windows based graphical user interface allowing developers to set critical parameters and observe changes to the touchscreen application in real time. Optimal configuration from the tuner are immediately applied to the TrueTouch user module settings. Page 5 of 32 [+] Feedback CY8CTST120 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. It 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 and 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 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 to tailor its precise configuration to a 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 to establish the pulse width and duty cycle. User modules also provide tested software to cut development time. The user module application programming interface (API) provides high level functions to control and respond to hardware events at run-time. The API also provides optional interrupt service routines that are adapted 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. Pick the user modules you need for your project and map them onto the PSoC blocks with point-and-click simplicity. Next, build signal chains by interconnecting user modules to each other and the IO pins. At this stage, 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, 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. Figure 4. User Module/Source Code Development Flows 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 The next step is to write the main program and any sub-routines using PSoC Designer's Application Editor subsystem. The Application Editor includes a Project Manager that allows 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 click the error message to view 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 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 such as monitoring address and data bus values, memory locations, and external signals.
