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 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 architecture for this device family, as shown in the Logical Block Diagram on page 2, consists of three main areas: ■ The Core ■ CapSense Analog System ■ WirelessUSB NL System ■ System Resources. A common, versatile bus allows connection between I/O and the analog system. 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 limits 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 superior noise immunity is well suited and handy for such applications to pass radiated and conducted noise test. Figure 1. CapSense System Block Diagram CS1 Each CYRF89435 device includes a dedicated CapSense block that provides sensing and scanning control circuitry for capacitive sensing applications. The 13 GPIOs provide access to the MCU and analog mux. IDAC Analog Global Bus 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. Reference Buffer Document Number: 001-76581 Rev. *D Cinternal Comparator 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 13 inputs. Capacitive sensing is configurable on each GPIO pin. Scanning of enabled CapSense pins are completed quickly and easily across multiple ports. 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 CSN Vr CapSense System SmartSense CS2 Cexternal (P0 or P0) Mux Mux Refs Cap Sense Counters CSCLK IMO CapSense Clock Select Oscillator Page 4 of 40 CYRF89435 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. On-chip transmit and receive FIFO registers are available to buffer the data transfer with MCU. Over-the-air data rate is always 1 Mbps even when connected to a slow, low-cost MCU. Built-in CRC, FEC, data whitening, and automatic retry/acknowledge are all available to simplify and optimize performance for individual applications. For more details on the radio’s implementation details and timing requriements, please go through the WirelessUSB NL datasheet in www.cypress.com. Figure 2. WirelessUSB NL logic Block Diagram WirelessUSB NL System WirelessUSB NL, optimized to operate in the 2.4-GHz ISM band, is Cypress's third generation of 2.4-GHz low-power RF technology. WirelessUSB NL implements a Gaussian frequency-shift keying (GFSK) radio using a differentiated single-mixer, closed-loop modulation design that optimizes power efficiency and interference immunity. Closed-loop modulation effectively eliminates the problem of frequency drift, enabling WirelessUSB NL to transmit up to 255-byte payloads without repeatedly having to pay power penalties for re-locking the phase-locked loop (PLL) as in open-loop designs Among the advantages of WirelessUSB NL are its fast lock times and channel switching, along with the ability to transmit larger payloads. Use of longer payload packets, compared to multiple short payload packets, can reduce overhead, improve overall power efficiency, and help alleviate spectrum crowding. Combined with Cypress's Capacitive touch sense controllers, WirelessUSB NL also provides the lowest bill of materials (BOM) cost solution for sophisticated PC peripheral applications such as wireless keyboards and mice, as well as best-in-class wireless performance in other demanding applications. such as toys, remote controls, fitness, automation, presenter tools, and gaming. With PRoC-CS, the WirelessUSB NL transceiver can add wireless capability to a wide variety of CapSense applications. The WirelessUSB NL is a fully-integrated CMOS RF transceiver, GFSK data modem, and packet framer, optimized for use in the 2.4-GHz ISM band. It contains transmit, receive, RF synthesizer, and digital modem functions, with few external components. The transmitter supports digital power control. The receiver uses extensive digital processing for excellent overall performance, even in the presence of interference and transmitter impairments. The product transmits GFSK data at approximately 0-dBm output power. Sigma-Delta PLL delivers high-quality DC-coupled transmit data path. The low-IF receiver architecture produces good selectivity and image rejection, with typical sensitivity of –87 dBm or better on most channels. Sensitivity on channels that are integer multiples of the crystal reference oscillator frequency (12 MHz) may show approximately 5 dB degradation. Digital RSSI values are available to monitor channel quality. Document Number: 001-76581 Rev. *D Transmit Power Control The following table lists recommended settings for register 9 for short-range applications, where reduced transmit RF power is a desirable trade off for lower current. Table 1. Transmit Power Control Power Setting Description Typical Transmit Power (dBm) Register 9 PA0 - Highest power +1 0x1820 PA2 - High power 0 0x1920 PA4 - High power –3 0x1A20 PA8 - Low power –7.5 0x1C20 PA12 - Lower power –11.2 0x1E20 Power-on and Register Initialization Sequence For proper initialization at power up, VIN must ramp up at the minimum overall ramp rate no slower than shown by TVIN specification in the following figure. During this time, the RST_n line must track the VIN voltage ramp-up profile to within approximately 0.2 V. Since most MCU GPIO pins automatically default to a high-Z condition at power up, it only requires a pull-up resistor. When power is stable and the MCU POR releases, and MCU begins to execute instructions, RST_n must then be pulsed Page 5 of 40 CYRF89435 low as shown in Figure 13 on page 32, followed by writing Reg[27 = 0x4200. During or after this SPI transaction, the State Machine status can be read to confirm FRAMER_ST= 1, indicating a proper initialization. Additional System Resources System resources provide additional capability, such as configurable I2C slave, SPI master/slave communication interface, three 16-bit programmable timers, and various system resets supported by the M8C. These system resources 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: I2C ■ The 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). ■ Low-voltage detection (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 reference provides an absolute reference for capacitive sensing. ■ A register-controlled bypass mode allows the user to disable the LDO regulator.

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. Document Number: 001-76581 Rev. *D 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 7 of 40 CYRF89435 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 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 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 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 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 Document Number: 001-76581 Rev. *D 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 automatically 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 environment 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 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. The interface lets you to define complex breakpoint events that include monitoring address and data bus values, memory locations, and external signals.

If powering down in standby sleep mode, to properly detect and recover from a VIN brown out condition any of the following actions must be taken: Bring the device out of sleep before powering down. Assure that VIN falls below 100 mV before powering back up. Set the No Buzz bit in the OSC_CR0 register to keep the voltage monitoring circuit powered during sleep. Increase the buzz rate to assure that the falling edge of VIN is captured. The rate is configured through 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 VIN brown out conditions to be detected for edge rates slower than 1V/ms. 6. Always greater than 50 mV above VPPOR1 voltage for falling supply. 7. Always greater than 50 mV above VPPOR2 voltage for falling supply. 8.

Differential non-linearity Ideally, any two adjacent digital codes correspond to output analog voltages that are exactly one LSB apart. Differential non-linearity is a measure of the worst case deviation from the ideal 1 LSB step. Hold time Hold time is the time following a clock event during which the data input to a latch or flip-flop must remain stable in order to guarantee that the latched data is correct. I2C It is a serial multi-master bus used to connect low speed peripherals to MCU. Integral nonlinearity It is a term describing the maximum deviation between the ideal output of a DAC/ADC and the actual output level. Latch-up current Current at which the latch-up test is conducted according to JESD78 standard (at 125 degree Celsius) Power supply rejection ratio (PSRR) The PSRR is defined as the ratio of the change in supply voltage to the corresponding change in output voltage of the device. Scan The conversion of all sensor capacitances to digital values. Setup time Period required to prepare a device, machine, process, or system for it to be ready to function. Signal-to-noise ratio The ratio between a capacitive finger signal and system noise. SPI Serial peripheral interface is a synchronous serial data link standard.
