Analog System Block Diagram The PSoC family consists of on-chip Controller devices. These devices are designed to replace multiple traditional MCU-based components with one, low cost single-chip programmable component. A PSoC device includes configurable analog and digital blocks, and programmable interconnect. This architecture allows the user 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. Analog Global Bus IDAC Vr The architecture for this device family, as shown in the Logic Block Diagram on page 2, is comprised of three main areas: the Core, the CapSense Analog System, and the System Resources (including a full speed USB port). A common, versatile bus allows connection between I/O and the analog system. Each CY8C20x36/46/66/96 PSoC Device includes a dedicated CapSense block that provides sensing and scanning control circuitry for capacitive sensing applications. Depending on the PSoC package, up to 36 general purpose IO (GPIO) are also included. The GPIO provides access to the MCU and analog mux. Reference Buffer Comparator Cinternal Mux Mux Refs PSoC Core CapSenseCounters 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 CPU core, called the M8C, is a powerful processor with speeds up to 24 MHz. The M8C is a 4-MIPS, 8-bit Harvard architecture microprocessor. System Resources provide additional capability, such as configurable USB and I2C slave/SPI master-slave communication interface, three 16-bit programmable timers, and various system resets supported by the M8C. The Analog System is composed of the CapSense PSoC block and an internal 1.2V analog reference, which together support capacitive sensing of up to 36 inputs. CapSense Analog System The Analog System contains the capacitive sensing hardware. Several hardware algorithms are supported. This hardware performs capacitive sensing and scanning without requiring external components. Capacitive sensing is configurable on each GPIO pin. Scanning of enabled CapSense pins are completed quickly and easily across multiple ports. CSCLK IMO CapSense Clock Select Oscillator Analog Multiplexer System The Analog Mux Bus can connect to every GPIO pin. Pins are connected to the bus individually or in any combination. The bus also connects to the analog system for analysis with the CapSense block comparator. 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: ■ Complex capacitive sensing interfaces, such as sliders and touchpads. ■ Chip-wide mux that allows analog input from any I/O pin. ■ Crosspoint connection between any I/O pin combinations. When designing capacitive sensing applications, refer to the latest signal-to-noise signal level requirements Application Notes, which can be found under http://www.cypress.com > Documentation > Application Notes. In general, and unless otherwise noted in the relevant Application Notes, the minimum signal-to-noise ratio (SNR) for CapSense applications is 5:1. Document Number: 001-12696 Rev. *F Page 3 of 39 [+] Feedback CY8C20X36/46/66/96 Additional System Resources System Resources, some of which are listed in the previous sections, provide additional capability useful to complete systems. Additional resources include low voltage detection and power on reset. The merits of each system resource are listed here: ■ The I2C slave/SPI master-slave module provides 50/100/400 kHz communication over two wires. SPI communication over three or four wires runs at speeds of 46.9 kHz to 3 MHz (lower for a slower system clock). ■ The I2C hardware address recognition feature reduces the already low power consumption by eliminating the need for CPU intervention until a packet addressed to the target device is received. ■ 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 reference provides an absolute reference for capacitive sensing. ■ A register-controlled bypass mode allows the user to disable the LDO. ■ Standard Cypress PSoC IDE tools are available for debugging the CY8C20x36/46/66/96 family of parts. However, the additional trace length and a minimal ground plane in the FlexPod can create noise problems that make it difficult to debug the design. A custom bonded On-Chip Debug (OCD) device is available in an 48-pin QFN package. The OCD device is recommended for debugging designs that have high current and/or high analog accuracy requirements. The QFN package is compact and is connected to the ICE through a high density connector.

Document Number: 001-12696 Rev. *F Page 4 of 39 [+] Feedback CY8C20X36/46/66/96 Development Tools PSoC Designer is a Microsoft® Windows-based, integrated development environment for the Programmable System-onChip (PSoC) devices. The PSoC Designer IDE and application runs on Windows XP and 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. PSoC Designer Software Subsystems System-Level View The system-level view is a drag-and-drop visual embedded system design environment based on PSoC Express. In this view you solve design problems the same way you might think about the system. Select input and output devices based upon system requirements. Add a communication interface and define the interface to the system (registers). Define when and how an output device changes state based upon any/all other system devices. Based upon the design, PSoC Designer automatically selects one or more PSoC devices 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.x. You 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. You configure the user modules for your chosen application and connect them to each other and to the proper pins. Then you 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 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 onchip resources. All views of the project share common code editor, builder, and common debug, emulation, and programming tools. Document Number: 001-12696 Rev. *F 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 be merged 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 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 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. In-Circuit Emulator A low cost, high functionality In-Circuit Emulator (ICE) 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. Page 5 of 39 [+] Feedback CY8C20X36/46/66/96 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 Select Components Organize and Connect You 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-todigital converter (ADC) to convert the potentiometer’s output to a digital signal, and a PWM to control the fan. In the chip-level view, you perform the selection, configuration, and routing so that you have complete control over the use of all on-chip resources. Both the system-level and chip-level views provide a library of pre-built, pre-tested 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 (I2Cbus, for example), and the logic to control how they interact with one another (called valuators). Generate, Verify, and Debug 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 programmable system-on-chip varieties. 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. 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 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. Document Number: 001-12696 Rev. *F 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. 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.

A Fast-Mode I2C-bus device can be used in a Standard Mode I2C-bus system, but the requirement tSU;DAT ≥ 250 ns must then be met. This automatically be 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 + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-Mode I2C-bus specification) before the SCL line is released. 13. In I2C sleep mode, wherein the part can wake up from sleep when the address matches its own slave address, there is no glitch/spike filtering on SCL and SDA lines on the 7-bit address + R/W bit.
