These devices are designed to replace multiple traditional MCU-based system components with one low cost single-chip programmable device. PSoC devices include configurable blocks of analog and digital logic, and programmable interconnects. This architecture enables the user to create customized peripheral configurations that 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 and packages. Digital System The Digital System is composed of eight digital PSoC blocks. Each block is an 8-bit resource that may be used alone or combined with other blocks to form 8, 16, 24, and 32-bit peripherals, which are called user module references. Figure 1. Digital System Block Diagram Port 3 Port 2 To System Bus Digital Clocks From Core The PSoC architecture, shown in Figure 1, consists of four main areas: PSoC Core, Digital System, Analog System, and System Resources. Configurable global busing allows the combining of all the device resources into a complete custom system. The PSoC family can have up to five I/O ports connecting to the global digital and analog interconnects, providing access to eight digital blocks and six analog blocks. Port 0 To Analog System DIGITAL SYSTEM Row 0 DBC00 DBC01 DCC02 4 DCC03 4 Row Output Configuration Row Input Configuration Digital PSoC Block Array 8 8 PSoC Core 8 Row Input Configuration 8 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 21 vectors, to simplify the programming of real time embedded events. Row 1 DBC00 GIE[7:0] GIO[7:0] Program execution is timed and protected using the included Sleep and watchdog timers (WDT). DBC01 DCC02 DCC03 Global Digital Interconnect Row Output Configuration The PSoC Core is a powerful engine that supports a rich feature set. The core includes a CPU, memory, clocks, and configurable general-purpose I/O (GPIO). Memory encompasses 16 KB of Flash for program storage, 1 K bytes of SRAM for data storage, and up to 2 KB of EEPROM emulated using the Flash. Program Flash uses four protection levels on blocks of 64 bytes, allowing customized software IP protection. Port 1 Port 4 GOE[7:0] GOO[7:0] Digital peripheral configurations are: ■ PWMs (8- and 16-Bit) ■ PWMs with Dead band (8- and 16-Bit) The PSoC device incorporates flexible internal clock generators, including a 24 MHz IMO (internal main oscillator). The 24 MHz IMO can also be doubled to 48 MHz for use by the digital system. A low power 32 kHz internal low-speed oscillator (ILO) is provided for the Sleep timer and WDT. If crystal accuracy is required, the ECO (32.768 kHz external crystal oscillator) is available for use as a Real Time Clock (RTC), and can optionally generate a crystal-accurate 24 MHz system clock using a PLL. The clocks, together with programmable clock dividers (as a System Resource), provide the flexibility to integrate almost any timing requirement into the PSoC device. ■ Counters (8 to 32-Bit) ■ Timers (8 to 32-Bit) ■ UART 8 Bit with Selectable Parity (Up to Two) ■ SPI Master and Slave (Up to Two) ■ Shift Register (1 to 32-Bit) ■ I2C Slave and Master (One Available as a System Resource) ■ Cyclical Redundancy Checker/Generator (8 to 32-Bit) PSoC GPIOs provide connection to the CPU, digital, and analog resources of the device. Each pin’s drive mode may be selected from eight options, allowing great flexibility in external interfacing. Every pin can also generate a system interrupt on high level, low level, and change from last read. ■ IrDA (Up to Two) ■ Pseudo Random Sequence Generators (8 to 32-Bit) The digital blocks may be connected to any GPIO through a series of global buses that can route any signal to any pin. The buses also allow for signal multiplexing and 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 provides a choice of system resources for your application. Family resources are shown in Table 1 on page 5. Document Number: 001-43084 Rev. *Q Page 3 of 39 CY8C21345 CY8C22345 CY8C22545 Analog System Additional System Resources The Analog System consists of a 10-bit SAR ADC and six configurable blocks. System Resources, some of which are listed in the previous sections, provide additional capability useful to complete systems. Additional resources include a MAC, low voltage detection, and power on reset. The merits of each system resource are: The programmable 10-bit SAR ADC is an optimized ADC that can be run up to 200 ksps with ± 1.5 LSB DNL and ± 2.5 LSB INL (true for VDD 3.0 V and Vref 3.0 V). External filters are required on ADC input channels for antialiasing. This ensures that any out-of-band content is not folded into the input signal band. Reconfigurable analog resources allow creating complex analog signal flows. Analog peripherals are very flexible and may be customized to support specific application requirements. Some of the more common PSoC analog functions (most available as user modules) are: ■ Analog-to-Digital converters (Single or Dual, with 8-bit resolution) ■ Pin-to-pin Comparator ■ Single ended comparators with absolute (1.3 V) reference or 5-bit DAC reference ■ 1.3 V reference (as a System Resource) Analog blocks are provided in columns of four, which include CT-E (Continuous Time) and SC-E (Switched Capacitor) blocks. These devices provide limited functionality Type “E” analog blocks. ■ Digital clock dividers provide three customizable clock frequencies for use in applications. The clocks may be routed to both the digital and analog systems. Additional clocks can be generated using digital PSoC blocks as clock dividers. ■ Additional Digital resources and clocks optimized for CSD. ■ Support “RTC” block into digital peripheral logic. ■ A multiply accumulate (MAC) provides a fast 8-bit multiplier with 32-bit accumulate, to assist in both general math and digital filters. ■ The I2C module provides 100 and 400 kHz communication over two wires. Slave, master, and multi-master modes are all supported. ■ 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 1.3 V reference provides an absolute reference for the analog system, including ADCs and DACs.

PSoC Designer software accelerates system design and time 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 user 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: 2 ❐ Hardware and software I 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 ADCs, 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 Document Number: 001-43084 Rev. *Q time. In essence, this allows 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 are 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 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, allowing 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 registers, set and clear breakpoints, and provide program run, halt, and step control. The debugger also allows 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-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 6 of 39 CY8C21345 CY8C22345 CY8C22545 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 is summarized in four steps: specifications. Each datasheet describes the use of each user module parameter, and other information you may need to successfully implement your design. Organize and Connect You build signal chains at the chip level by interconnecting user modules to each other and the I/O pins. You perform the selection, configuration, and routing so that you have complete control over all on-chip resources. 1. Select User Modules. Generate, Verify, and Debug 2. Configure User Modules. 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. The generated code 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. 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 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. All 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 Document Number: 001-43084 Rev. *Q A complete code development environment allows you to develop and customize your applications in either 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. These include monitoring address and data bus values, memory locations, and external signals.

See hardware reset and software reset. ROM An acronym for read only memory. A data-storage device from which data can be read out, but new data cannot be written in. serial 1. Pertaining to a process in which all events occur one after the other. 2. Pertaining to the sequential or consecutive occurrence of two or more related activities in a single device or channel. settling time The time it takes for an output signal or value to stabilize after the input has changed from one value to another. Document Number: 001-43084 Rev. *Q Page 33 of 39 CY8C21345 CY8C22345 CY8C22545 Glossary (continued) shift register A memory storage device that sequentially shifts a word either left or right to output a stream of serial data. slave device A device that allows another device to control the timing for data exchanges between two devices. Or when devices are cascaded in width, the slave device is the one that allows another device to control the timing of data exchanges between the cascaded devices and an external interface. The controlling device is called the master device. SRAM An acronym for static random access memory. A memory device allowing users to store and retrieve data at a high rate of speed. The term static is used because, after a value has been loaded into an SRAM cell, it remains unchanged until it is explicitly altered or until power is removed from the device. SROM An acronym for supervisory read only memory. The SROM holds code that is used to boot the device, calibrate circuitry, and perform Flash operations. The functions of the SROM may be accessed in normal user code, operating from Flash. stop bit A signal following a character or block that prepares the receiving device to receive the next character or block. synchronous 1. A signal whose data is not acknowledged or acted upon until the next active edge of a clock signal. 2. A system whose operation is synchronized by a clock signal. tri-state A function whose output can adopt three states: 0, 1, and Z (high-impedance). The function does not drive any value in the Z state and, in many respects, may be considered to be disconnected from the rest of the circuit, allowing another output to drive the same net. UART A UART or universal asynchronous receiver-transmitter translates between parallel bits of data and serial bits. user modules Pre-build, pre-tested hardware/firmware peripheral functions that take care of managing and configuring the lower level Analog and Digital PSoC Blocks. User Modules also provide high level API (Application Programming Interface) for the peripheral function. user space The bank 0 space of the register map. The registers in this bank are more likely to be modified during normal program execution and not just during initialization. Registers in bank 1 are most likely to be modified only during the initialization phase of the program. VDD A name for a power net meaning "voltage drain." The most positive power supply signal. Usually 5 V or 3.3 V. VSS A name for a power net meaning "voltage source." The most negative power supply signal. watchdog timer A timer that must be serviced periodically. If it is not serviced, the CPU resets after a specified period of time.

Items Part Number Silicon Revision Fix Status 1. Free Running Nonstop Reading All CY8C21x45, CY8C22x45 cause 7 LSB Pseudo Code Variation devices affected in SAR10ADC All Silicon fix not planned. Use workaround. 2. Internal Main Oscillator (IMO) All CY8C21x45, CY8C22x45 Tolerance Deviation at Temperature devices affected Extremes All Silicon fix not planned. Use workaround. 1. Free Running Nonstop Reading cause 7 LSB Pseudo Code Variation in SAR10ADC ■ Problem Definition In free running mode, there can be a variation of up to 7 LSB in the digital output of SAR10 ADC. ■ Parameters Affected Code Variation. This is not a specified parameter. It is defined as the number of unique output codes generated by the ADC for a given constant input voltage, in addition to the correct code. For example, for an input voltage of 2.000 V, the expected code is 190hex and the ADC generates three codes: 191hex, 190hex, and 192hex. The code variation is 2 LSB. ■ Trigger Condition(S) SAR10 ADC is configured in the free running mode. ■ Scope of Impact Inaccurate output is possible. ■ Workaround This issue can be averted by using one or both of the following workarounds. Consult a Cypress representative for additional assistance. ❐ Use the averaging technique. That is, take multiple samples of the input, and use a digital averaging filter. ❐ Disable the free running mode before reading data out, and enable the free running mode after completing the read operation. ■ Fix Status No silicon fix is planned. Document Number: 001-43084 Rev. *Q Page 35 of 39 CY8C21345 CY8C22345 CY8C22545 2. Internal Main Oscillator (IMO) Tolerance Deviation at Temperature Extremes ■ Problem Definition Asynchronous Digital Communications Interfaces may fail framing beyond 0 to 70 °C. This problem does not affect end-product usage between 0 and 70 °C. ■ Parameters Affected The IMO frequency tolerance. The worst case deviation when operated below 0 °C and above +70 °C and within the upper and lower datasheet temperature range is ±5%. ■ Trigger Condiiton(S) The asynchronous Rx/Tx clock source IMO frequency tolerance may deviate beyond the datasheet limit of ±2.5% when operated beyond the temperature range of 0 to +70 °C. ■ Scope of Impact This problem may affect UART, IrDA, and FSK implementations. ■ Workaround Implement a quartz crystal stabilized clock source on at least one end of the asynchronous digital communications interface. ■ Fix Status The cause of this problem and its solution has been identified. No silicon fix is planned to correct the deficiency in silicon.
