Each block is an 8-bit resource that can be used alone or combined with other blocks to form 8-, 16-, 24-, and 32-bit peripherals, which are called user modules. Figure 2. Digital System Block Diagram Port 5 Port 1 Port 2 Digital Clocks FromCore To System Bus Port 0 ToAnalog System DIGITAL SYSTEM Digital PSoC Block Array PSoC Core Row 0 DBB00 DBB01 DCB02 4 DCB03 4 8 8 8 Row Input Configuration Row 1 DBB10 DBB11 DCB12 4 DCB13 4 GIE[7:0] GIO[7:0] Global Digital Interconnect 8 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 GPIO. 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 17 vectors, to simplify programming of real time embedded events. Program execution is timed and protected using the included sleep and watchdog timers (WDT). Memory encompasses 16 KB of flash for program storage, 256 bytes of SRAM for data storage, and up to 2 K of EEPROM emulated using the flash. Program flash uses four protection levels on blocks of 64 bytes, allowing customized software IP protection. The PSoC device incorporates flexible internal clock generators, including a 24-MHz internal main oscillator (IMO) accurate to 2.5% over temperature and voltage. 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 desired, the 32.768-kHz external crystal oscillator (ECO) 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. 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 also has the capability to generate a system interrupt on high level, low level, and change from last read. Port 3 Port 4 Row Output Configuration The PSoC family consists of many programmable system-on-chip controller devices. These devices are designed to replace multiple traditional microcontroller unit (MCU)-based system components with one, low-cost single-chip programmable device. PSoC devices include configurable blocks of analog and digital logic, as well as programmable interconnects. This architecture lets you to create customized peripheral configurations that match the requirements of each individual application. Additionally, a fast central processing unit (CPU), flash program memory, SRAM data memory, and configurable I/O are included in a range of convenient pinouts and packages. The PSoC architecture, as illustrated in Logic Block Diagram on page 1, consists of four main areas: PSoC core, digital system, analog system, and system resources. Configurable global busing allows all the device resources to be combined into a complete custom system. The PSoC CY8C27x43 family can have up to five I/O ports that connect to the global digital and analog interconnects, providing access to eight digital blocks and 12 analog blocks. Digital System Row Input Configuration PSoC Functional Overview GOE[7:0] GOO[7:0] Digital peripheral configurations include: ■ PWMs (8- and 16-bit) ■ PWMs with dead band (8- and 16-bit) ■ Counters (8- to 32-bit) ■ Timers (8- to 32-bit) [1, 2] ■ UART 8-bit with selectable parity (up to two) ■ SPI slave and master (up to two) [3] ■ I2C slave and multi-master (one available as a system resource) ■ CRC/generator (8- to 32-bit) ■ IrDA (up to two) ■ Pseudo random sequence (PRS) generators (8- to 32-bit) Notes 1.

AD Page 6 of 69 CY8C27143/CY8C27243 CY8C27443/CY8C27543 CY8C27643 Development Tools PSoC Designer™ is the 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 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 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: 38-12012 Rev. AD 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 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 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-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 69 CY8C27143/CY8C27243 CY8C27443/CY8C27543 CY8C27643 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: 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 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. 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 specifications. Each datasheet describes the use of each user module parameter, and other information you may need to successfully implement your design. Document Number: 38-12012 Rev. AD 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. Generate, Verify, and Debug 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. A complete code development environment lets 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 lets you to define complex breakpoint events that include monitoring address and data bus values, memory locations and external signals.

This may be balanced between operations on 36x1 blocks of 50,000 maximum cycles each, 36 × 2 blocks of 25,000 maximum cycles each, or 36 × 4 blocks of 12,500 maximum cycles each (to limit the total number of cycles to 36 × 50,000 and that no single block ever sees more than 50,000 cycles). For the full industrial range, you must employ a temperature sensor user module (FlashTemp) and feed the result to the temperature argument before writing.

Many interrupt sources may each exist with its own priority and individual ISR code block. Each ISR code block ends with the RETI instruction, returning the device to the point in the program where it left normal program execution. jitter 1. A misplacement of the timing of a transition from its ideal position. A typical form of corruption that occurs on serial data streams. 2.

(LVD) M8C An 8-bit Harvard-architecture microprocessor. The microprocessor coordinates all activity inside a PSoC by interfacing to the Flash, SRAM, and register space. master device A device that controls the timing for data exchanges between two devices. Or when devices are cascaded in width, the master device is the one that controls the timing for data exchanges between the cascaded devices and an external interface. The controlled device is called the slave device. Document Number: 38-12012 Rev. AD Page 58 of 69 CY8C27143/CY8C27243 CY8C27443/CY8C27543 CY8C27643 Glossary (continued) microcontroller An integrated circuit chip that is designed primarily for control systems and products. In addition to a CPU, a microcontroller typically includes memory, timing circuits, and IO circuitry. The reason for this is to permit the realization of a controller with a minimal quantity of chips, thus achieving maximal possible miniaturization. This in turn, reduces the volume and the cost of the controller. The microcontroller is normally not used for general-purpose computation as is a microprocessor. mixed-signal The reference to a circuit containing both analog and digital techniques and components. modulator A device that imposes a signal on a carrier. noise 1. A disturbance that affects a signal and that may distort the information carried by the signal. 2. The random variations of one or more characteristics of any entity such as voltage, current, or data. oscillator A circuit that may be crystal controlled and is used to generate a clock frequency. parity A technique for testing transmitting data. Typically, a binary digit is added to the data to make the sum of all the digits of the binary data either always even (even parity) or always odd (odd parity). Phase-locked loop (PLL) An electronic circuit that controls an oscillator so that it maintains a constant phase angle relative to a reference signal. pinouts The pin number assignment: the relation between the logical inputs and outputs of the PSoC device and their physical counterparts in the printed circuit board (PCB) package. Pinouts involve pin numbers as a link between schematic and PCB design (both being computer generated files) and may also involve pin names. port A group of pins, usually eight. Power on reset (POR) A circuit that forces the PSoC device to reset when the voltage is lower than a pre-set level. This is a type of hardware reset. PSoC® Cypress Semiconductor’s PSoC® is a registered trademark and Programmable System-on-Chip™ is a trademark of Cypress.

Document Number: 38-12012 Rev. AD Page 59 of 69 CY8C27143/CY8C27243 CY8C27443/CY8C27543 CY8C27643 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 where you can store and retrieve data at a high rate of speed. The term static is used because, after a value is 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. Document Number: 38-12012 Rev.

Internal Main Oscillator (IMO) Tolerance Deviation at Temperature Extremes. B No silicon fix planned. Workaround is required. All devices 1. Reading from chained SPI slaves does not give correct results. ■ Problem Definition When multiple Digital Communication Blocks are configured as SPI Slave devices and one SPI’s output (MISO) is connected to the input (MOSI) of the second SPI, the serial data will be correctly forwarded, but reading the results from the DCBxxDR2 register in the second device will result in the last bit shifted in being incorrect. ■ Parameters Affected NA ■ Trigger Condition Connection of the output of one PSoC SPI slave to the input of another PSoC SPI slave. ■ Scope of Impact PSoC end user designs incorporating SPI configurations with multiple Digital Communication Blocks configured as SPI Slave devices with one SPI output (MISO) connected to the input (MOSI) of the second SPI. ■ Workaround This solution requires the use of an additional digital block configured as a PWM8 set for a 50% duty cycle. The same clock is routed to the PWM8, as goes to the two SPI slaves. The PWM8 User Module is parameterized to have a Period of 15 (so that it divides by 16) and a pulse width of 8 (with CompType set to “Less Than Or Equal” (so that it has a “1” pulse width of 8 clocks and a “0” pulse width of 8 clocks). The output of the PWM8 is connected to the Slave Select (/SS) of each SPI slave. One of these connections is direct. The other connection is inverted using the row output LUT. This configuration will “ping pong” the two SPIs so that each one receives alternating bytes. This solution works especially well in cases where the two SPI slaves are being used to implement a 16-bit shift register, the following method has worked. ■ Fix Status There are no fixes planned. The workaround listed above should be used. Document Number: 38-12012 Rev. AD Page 61 of 69 CY8C27143/CY8C27243 CY8C27443/CY8C27543 CY8C27643 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 Condition(s) The asynchronous Rx/Tx clock source IMO frequency tolerance may deviate beyond the data sheet 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 There are no fixes planned. The workaround listed above should be used. Document Number: 38-12012 Rev. AD Page 62 of 69 CY8C27143/CY8C27243 CY8C27443/CY8C27543 CY8C27643 Not in Production Part Numbers Affected Part Number CY8C27143 CY8C27243 CY8C27443 CY8C27543 CY8C27643 Qualification Status CY8C27X43 Rev. A – Not in production Errata Summary The following table defines the errata applicability to available devices. Items Part Number Silicon Revision Fix Status 1. The Timer Capture Input signal is limited to re-synchronized Row Inputs or Analog Comparator bus inputs when operating over 4.75 V. All parts affected A Fix confirmed in Silicon Rev B 2. The Timer Capture Inputs are limited to re-synchronized Row Inputs when operating at less than 4.75 V. All parts affected A Fix confirmed in Silicon Rev B 3. The I2C_CFG, I2C_SCR, and I2C_MSCR registers have some restrictions as to the CPU frequency that must be in effect when these registers are written. All parts affected A Fix confirmed in Silicon Rev B 1. The Timer Capture Input signal is limited to re-synchronized Row Inputs or Analog Comparator bus inputs when operating over 4.75 V. ■ Problem Definition When the device is operating at 4.75 V to 5.25 V, the Input Capture signal source for a digital block operating in Timer mode is limited to either a Row Input signal that has been re-synchronized, or an Analog Comparator bus input. The Row Output signals, or the Broadcast clock signals, cannot be used as a source for the Timer Capture signal. ■ Parameters Affected NA ■ Trigger Condition(S) Device operating with VCC between 4.75 V to 5.25 V. ■ Scope of Impact Digital blocks operating in timer mode and user modules relying on the timer's output are affected by this errata element. ■ Workaround To connect the Input Capture signal to the output of another block in the same row, run the output of that block to a Row Output, then to a Global Output, then back to a Global Input, then a Row Input, where the signal can be resynchronized. When connecting the Input Capture signal to an output of a block in a different row, the connection will naturally follow the path of Global Output, to Global Input, then to Row Input. ■ Fix Status Fix in silicon rev B Document Number: 38-12012 Rev. AD Page 63 of 69 CY8C27143/CY8C27243 CY8C27443/CY8C27543 CY8C27643 2. The Timer Capture Inputs are limited to re-synchronized Row Inputs when operating at less than 4.75 V. ■ Problem Definition When the device is operating at 3.0 V to 4.75 V, the Input Capture signal source for a digital block operating in Timer mode is limited to a Row Input signal that has been re-synchronized. Maximum width is 16-bits Timer Capture less than 4.75 V. The Row Output signals, Analog Comparator input signals, or the Broadcast Clock signals cannot be used as a source for the Timer Capture signal. ■ Parameters Affected NA ■ Trigger Condition(S) Device operating with VCC between 3.0 V to 4.75 V. ■ Scope of Impact Digital blocks operating in timer mode and user modules relying on the timer's output are affected by this errata element. ■ Workaround To connect the input capture signal to the output of another block, run the output of that block to a row output, then to a global output, back to a global input, then a row input, where the signal can be re-synchronized. To connect an analog comparator bus signal to an input capture, this signal must be routed to pass through a re-synchronizer. The only way this can be accomplished is to route the analog comparator on an analog output bus to connect with an I/O pin. This will use up the resource of the analog output bus, and even though this bus is designed for analog signals, the digital signal from the Analog Comparator operates correctly when transmitted on this bus. After the signal reaches the pin, it is converted back to a digital signal and is communicated back to the digital array using the global input bus for that pin. To make this connection, the port pin must be setup with the global input bus enabled. To enable this configuration within PSoC Designer™, first turn ON the analog output, and then enable the global input. Figure 30. Resynchronized ■ Fix Status Fix in silicon rev B 3. The I2C_CFG, I2C_SCR, and I2C_MSCR registers have some restrictions as to the CPU frequency that must be in effect when these registers are written. ■ Problem Definition The CPU frequency must be set to one of the recommended values just prior to a write to these registers and can be immediately set back to the original operating frequency in the instruction just following the register write. A write instruction to these registers occurring at a CPU frequency that is not recommended could result in unpredictable behavior. The table below lists the possible selections of the CPU memory for writes to the I2C_CFG, I2C_SCR, and I2C_MSCR registers, and it highlights the particular settings that are recommended (Rec) and not recommended (NR).

This user module has a parameter that must be set by users of CY8C27x43 Silicon Revision A devices. When this parameter is set, the user module code temporarily changes the CPU frequency to the recommended values when writing to the affected registers. Users of PSoC Designer should download and install the PSoC Designer 4.1 Service Pack 1 which is available on the web at http://www.cypress.com/psoc. ■ Fix Status Fix in silicon rev B.
