4 / 33 page  CY8C20336H, CY8C20446H Document Number: 001-56223 Rev. *C Page 4 of 33 PSoC® Functional Overview The PSoC family consists of 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 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 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 the I/O and the analog system. Each CY8C20336H/446H 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 28 GPIOs are also included. The GPIOs provide 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 28 inputs[2]. 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. Figure 1. CapSense System Block Diagram 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. Haptics TS2000 Controller The CY8C20336H/CY8C20446H family of devices feature an easy-to-use Haptics controller resource with up to 14 different effects. These effects are available for use with three different, selectable ERM modules. Note 2. 36 GPIOs = 33 pins for capacitive sensing + 2 pins for I2C + 1 pin for modulator capacitor.
