cy7c604xx document number: 001-12395 rev. *n page 3 of 38 functional overview the encore v lv family of devices are designed to replace multiple traditional low voltage microcontroller system compo - nents with one, low cost single chip programmable component. co mmunication peripherals (i 2 c/spi), 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 illustrated in encore v lv block diagram , is comprised of two main areas: the cpu core and the system resources. depending on the encore v lv p ackage, up to 36 gpio are also included. enhancements over the cypress?s legacy low-voltage microcon - trollers include faster cpu at lower voltage operation, lower curre nt consumption, twice the ram and flash, hot-swapable i/os, i 2 c hardware address recognition, new very low-current sleep mode, and new package options. the encore v lv core the encore v lv 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 (internal main oscillator) and ilo (internal low-speed oscillator). the cpu core, called the m8c, is a powerful processor with speeds up to 24 mhz. the m8c is a four-mips, 8-bit harvard architecture microprocessor. system resources provide additional capability, such as a con figurable i 2 c slave and spi master-slave communication interface and various system re sets supported by the m8c. 10-bit adc the adc on encore v lv device is an independent block with a state machine interface to control accesses to the block. the adc is housed together with the temperature sensor core and can be connected to this or the analog mux bus. as a default operation, the adc is connected to the temperature sensor diodes to give digital values of the temperature. figure 1. interface block command/ status adc temp diodes v in system bus temp sensor/ adc interface to the m8 c ( processor ) core adc system performance block diagram the adc user module contains an integrator block and one comparator with positive and nega tive input set by the muxes. the input to the integrator stage comes from the analog global input mux or the temperature sensor with an input voltage range of 0 v to 1.3 v, where 1.3 v is 72% of full scale. in the adc only configuration (the adc mux selects the analog mu x bus, not the default temperature sensor connection), an external voltage can be connected to the input of the modulator for voltage conversion . the adc is run for a number of cycles set by the timer, depending upon the resolution of the adc desired by the user. a counter counts the number of trips by the comparator, which is proportional to the input voltage. the temp sensor block clock speed is 36 mhz and is divided down to 1 to 12 mhz for adc operation.
cy7c604xx document number: 001-12395 rev. *n page 4 of 38 spi the serial peripheral interconne ct (spi) 3-wire protocol uses both edges of the clock to enable synchronous communication without the need for stringent setup and hold requirements. figure 2. basic spi configuration mosi miso sclk data is output by both the master and slave on one edge of the clock. data is registered at the input of both devices on the opposite edge of the clock. a device can be a master or slave. a master outputs clock and data to the slave device and inputs slave data. a slave device inputs clock and data from the master device and outputs data for input to the master. together, the master and slave are essen - tially a circular shift register , where the master generates the clocking and initiates data transfers. a basic data transfer occurs when the master sends eight bits of d ata, along with eight clocks. in any transfer, both master and slave transmit and receive simultaneously. if the master only sends data, the received data from the slave is ignored. if the master wishes to receive data fr om the slave, the master must send dummy bytes to generate the clocking for the slave to send data back. figure 3. spi block registers sysclk data_out data_in clk_in clk_out int ss_ sclk mosi, miso sclk mosi, miso configuration[7:0] control[7:0] transmit[7:0] receive[7:0] spi block diagram spi configuration register ( spi_cfg) set s master/slave functionality, clock speed and interrupt select. spi control register (spi_cr) provides four co ntrol bits and four status bits for device interfacing and synchronization. the spim hardware has no support for driving the slave select (ss_) sign al. the behavior and use of this signal is application and encore v device dependent and, if re quired, must be imple - mented in firmware. there is an additional data input in the spis, slave select (ss_), w hich is an active low signal. ss_ must be asserted to enable the spis to receive and transmit. ss_ has two high level functions: 1) to allow for the selection of a given slave in a multi-slave environment, and 2) to provide additional clocking for tx data queuing in spi modes 0 and 1. i 2 c slave the i 2 c slave enhanced communications block is a serial-to-parallel processor, designed to interface the encore v lv device to a two-wire i 2 c serial communications bus. to eliminate the need for excessive cpu intervention and overhead, the block provides i 2 c-specific support for status detection and generation of fr aming bits. by default, the i 2 c slave enhanced module is firmware compatible with the previous generation of i 2 c slave functionality. however, this module provides new features that are configurable to implement significant flexibilit y for both internal and external interfacing. figure 4. i2c core i2c basic configuration i2c_cfg i2c_scr i2c_dr plus features hw addr cmp buffer module cpu port buffer ctl 32 byte ram i2c plus slave i2c_addr sda_out scl_in sysclk i2c_en to/from gpio pins standby scl_out sda_in i2c_xstat i2c_xcfg i2c_buf i2c_bp i2c_cp mcu_cp mcu_bp system bus i 2 c block diagram
cy7c604xx document number: 001-12395 rev. *n page 5 of 38 the basic i 2 c features include: slave, transmitter, and receiver operation byte processing for low cpu overhead interrupt or polling cpu interface support for clock rate s of up to 400 khz 7- or 10-bit addressing (through firmware support) smbus operation (through firmware support) enhanced features of the i 2 c slave enhanced module include: support for 7-bit hardware address compare flexible data buffering schemes a ?no bus stalling? operating mode a low power bus monitoring mode the i 2 c block controls the data (sda) and the clock (scl) to the external i 2 c interface through direct connections to two dedicated gpio pins. when i 2 c is enabled, these gpio pins are not available for general purpose use. the encore v lv cpu firmware interacts with the block through i/o register reads and writes, and firmware synchronization is implemented through polling and/or interrupts. in the default operating mode, which is firmware compatible with previous versions of i 2 c slave modules, the i 2 c bus is stalled upon every received address or byte, and the cpu is required to read the data or supply data as required before the i 2 c bus continues. however, this i 2 c slave enhanced module provides new data buffering capability as an enhanced feature. in the ezi 2 c buffering mode, the i 2 c slave interface appears as a 32-byte ram buffer to the external i 2 c master. using a simple predefined protocol, the master controls the read and write pointers into the ram. when this method is enabled, the slave never stalls the bus. in this protocol, the data available in the ram (this is managed by the cpu) is valid. additional system resources system resources, some of whic h have been previously listed, provide additional capability useful to complete systems. additional resources include low voltage detection and power on reset. the following statements describe the merits of each system resource: low-voltage detection (lvd) interrupts can signal the appli - cation of falling voltage levels, while the advanced power-on reset (por) circuit eliminates the need for a syst em supervisor. the 3.6 v maximum input, 1.8, 2. 5, or 3 v selectable output, low dropout regulator (ldo) provides regulation for i/os. a register controlled bypass mode enables the user to disable the ldo. standard cypress psoc ide tools are available for debugging the encore v lv family of parts. getting started the quickest way to understanding the encore v silicon is by reading this datasheet and using the psoc designer integrated development environment (ide). this datasheet is an overview of the encore v integrated circui t and presents specific pin, register, and electrical specifications. for in-depth information, along with detailed programming information, refer to the psoc programmable system-on-chip technical reference manual , for cy8c28xxx psoc devices. for up-to-date ordering, packaging, and electrical specification information, reference the latest encore v device datasheets on the web at http://www.cypress.com . application notes cypress application notes are an excellent introduction to the wide variety of possi ble psoc designs. development kits psoc development kits are available online from and through a growing number of regional and global distributors, which include arrow, avnet, digi-key, farnell, future electronics, and newark. training free psoc technical training (on demand, webinars, and workshops), which is available online via www.cypress.com , covers a wide variety of topics an d skill levels to assist you in your designs. cypros consultants certified psoc consultants offer everything from technical assis- tance to completed psoc designs. to contact or become a psoc consultant go to the cypros consultants web site. solutions library visit our growing library of solution focused designs . here you can find various application designs that include firmware and hardware design files that enable you to complete your designs quickly. technical support technical support ? including a searchable knowledge base articles and technical forums ? is also available online. if you cannot find an answer to your question, call our technical support hotline at 1-800-541-4736.
cy7c604xx document number: 001-12395 rev. *n page 6 of 38 development tools psoc designer? is the revolutionary integrated design environment (ide) that you can use to customize psoc to meet your specific application require ments. 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, incl uding 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: hardware and software i 2 c slaves and masters full-speed usb 2.0 up to four full-duplex universal asynchronous receiver/trans - mitters (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 (d acs), 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 configura - tions and dynamic reconfigurat ion. 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 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, 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 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 on line, context-sensitive help. designed for procedural and quick reference, each functional subsystem has its own context-s ensitive 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 emulat ion pod takes the place of the psoc device in the target board and performs full-speed ?
cy7c604xx document number: 001-12395 rev. *n page 7 of 38 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 ps oc 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 select ed 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 param - eters 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 specifi - cations. each datasheet describes the use of each user module parameter, and other information that you may need to success - fully 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 automatic ally 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 capabil - ities rival those of systems cost ing 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.
