on-chip controller devices, which are designed to replace multiple traditional microcontroller unit (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 configurat ions, 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 architecture for this device family, as shown in the logic block diagram on page 2 , consists of three main areas: the core capsense analog system system resources (including a full-speed usb port). a common, versatile bus allows connection between i/o and the analog system. each cy8c20x36a/46a/66a/ 96a/46as/66as psoc device includes a dedicated capsense bl ock that provides sensing and scanning control circuitry for capacitive sensing applications. depending on the psoc package, up to 36 gpio are also included. the gpio provides access to the mcu and analog mux. 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 imo and ilo. 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. capsense 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. the analog system is composed of the capsense psoc block and an internal 1 v or 1.2 v analog reference, which together support capacitive sensing of up to 33 inputs [3] . capacitive sensing is configurable on each gpio pin. scanning of enabled capsense pins are completed quickly and easily across multiple ports. smartsense smartsense is an innovative solution from cypress that removes manual tuning of capsense applications. this solution is easy to use and provides a robust noise immunity. it is the only auto-tuning solution that establishes, monitors, and maintains all required tuning parameters. smartsense allows engineers to go from prototyping to mass production without re-tuning for manufacturing variations in pcb and/or overlay material properties. smartsense_emc in addition to the smartsense auto tuning algorithm to remove manual tuning of capsense applications, smartsense_emc user module incorporates a unique algorithm to improve robustness of capacitive sensing algorithm/circuit against high frequency conducted and radiated noise. every electronic device must comply with specific lim its for radiated and conducted external noise and these limits are specified by regulatory bodies (for example, fcc, ce, u/l and so on). a very good pcb layout design, power supply design and system design is a mandatory for a product to pass the conducted and radiated noise tests. an ideal pcb layout, power supply design or system design is not often possible because of cost and form factor limitations of the product. smartsense_emc with s uperior noise immunity is well suited and handy for such applications to pass radiated and conducted noise test. figure 1. capsense system

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 analo g 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 su ch as touch sensing. other multiplexer applications include: complex capacitive sensing in terfaces, 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. additional system resources system resources provide additional capability, such as configurable usb and i 2 c slave, spi master/slave communication interface, three 16-bit programmable timers, and various system resets supported by the m8c. these system resources provide additional capabi lity useful to complete systems. additional resources include low voltage detection and power on reset. the merits of each system resource are listed here: the i 2 c slave/spi master-slave module provides 50/100/400 khz communication over two wires. spi communication over three or f our wires runs at speeds of 46.9 khz to 3 mhz (lower for a slower system clock). low-voltage detection (lvd) interrupts can signal the application of falling voltage levels, while the advanced power-on-reset (por) circuit e liminates 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 regulator. cy8c20x36a/46a/6 6a/96a/46as/66as document number: 001-54459 rev. *o page 6 of 47 getting started the quickest way to understand psoc silicon is to read

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 ti me 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 us er 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: ? hardware and software i 2 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 analog-to-digital converters (adcs), digital-to-analog converters (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 lets you to use more than 100 percent of psoc?s resources for an application. 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 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 fo r 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, al lowing 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 regist ers, set and clear breakpoints, and provide program run, halt , and step control. the debugger also lets 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-se nsitive help. th is 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 ba se unit that connects to the pc using a usb port. the base unit is universal and operates with all psoc devices. emulation p ods 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. cy8c20x36a/46a/6 6a/96a/46as/66as document number: 001-54459 rev. *o page 8 of 47 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 divi dends in managing specification change during development and lowering inventory costs. these configurable resources, called psoc blocks, have the ability to implement a wide variety of use r-selectable functions. the psoc development process is: 1. select user modules . 2. configure user modules. 3. organize and connect. 4. generate, verify, and debug. select user modules psoc designer provides a library of prebuilt, pretested hardware peripheral components called ?user modules?. user modules make selecting and implementing peripheral devices, both analog and digital, simple. configure user modules each user module that 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 eight bits of resolution. using these parameters, you can establish the pulse width an d 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 of 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 that you may need to successfully implement your design. organize and connect build signal chains at the chip level by interconnecting user modules to each other and the i/o pins. perform the selection, configuration, and routing so that you have complete control over all on-chip resources. 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 configuration files? step. this causes psoc designer to generate source code that automat ically configures the device to your specification and provides the software for the system. the generated code provides 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. a complete code development en vironment lets 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 (accessed 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 syst ems 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. it lets you to define complex breakpoint events that include monitoring address and data bus values, memory locations, and external signals. cy8c20x36a/46a/6 6a/96a/46as/66as document number: 001-54459 rev. *o page 9 of 47 pinouts the cy8c20x36a/46a/66a/96a/46as/66as psoc device is available in a

in-circuit debugging during prototype development. it is not available in p roduction volumes. 30. the center pad (cp) on the qfn package must be connected to ground (v ss ) for best mechanical, thermal, and electrical performance. if not connected to ground, it must be electrically floated an d not connected to any other signal. 31. this pin (associated with ocd part only) is required for connec ting the device to ice-cube in-circuit emulator for firmware debugging purpose. to know more about the usage of ice-cube, refer to cy3215-dk psoc ? in-circuit emulator kit guide . 32. on power-up, the sda(p1[0]) drives a strong high for 256 sle ep clock cycles and drives resistive low for the next 256 sleep clock cycles. the scl(p1[1]) line drives resistive low for 512 sleep clock cycles and both the pins transition to high impedance state. on reset, after xres de- asserts , the sda and the scl lines drive resistive low for 8 sleep clock cycles and transition to high imped ance state. in both cases, a pull-up resistance on these lin es combines with the pull-down resistance (5.6k ohm) and form a potential divider. hence, during power-up or reset event, p1[1] and p1[0] may disturb the i2c bus. use al ternate pins if you encounter issues. 33. alternate spi clock. cy8c20x36a/46a/6 6a/96a/46as/66as document number: 001-54459 rev. *o page 19 of 47 electrical specifications

notes 35. when v dd remains in the range from 1.71 v to 1.9 v for more than 50 s, t he slew rate when moving from the 1.71 v to 1.9 v range to gre ater than 2 v must be slower than 1 v/500 s to avoid triggering por. the only other re striction on slew rates for any other voltage range or transit ion is the sr power_up parameter. 36. if powering down in standby sleep mode, to properly detect and recover from a v dd brown out condition any of the following actions must be taken: a.bring the device out of sleep before powering down. b.assure that v dd falls below 100 mv before powering back up. c.set the no buzz bit in the osc_cr0 register to k eep the voltage monitoring circuit powered during sleep. d.increase the buzz rate to assu re that the falling edge of v dd is captured. the rate is configured th rough the pssdc bits in the slp_cfg register. for the referenced registers, refer to the cy8c20x36 technical reference manual . in deep sleep mode, additional low power voltage monitoring circuitry allows v dd brown out conditions to be detected for edge rates slower than 1v/ms. 37. for usb mode, the v dd supply for bus-powered application should be limited to 4.35 v?5.35 v. for self-powered application, v dd should be 3.15 v?3.45 v. 38. for proper capsense block f unctionality, if the drop in v dd exceeds 5% of the base v dd , the rate at which v dd drops should not exceed 200 mv/s. base v dd can be between 1.8 v and 5.5 v cy8c20x36a/46a/6 6a/96a/46as/66as document number: 001-54459 rev. *o page 21 of 47 dc gpio specifications the following tables list guaranteed
