cypress公司的PSoC 4200DS是可升级和可配置的具有ARM® Cortex™-M0 CPU的可编程嵌入系统控制器平台架构,包括有可编程和可配置模拟和数字区块以及灵活的自动走线,组合了MCU和可编程数字可编程逻辑,可编程互连,标准通信和定时外设,支持编程,测试,调试和硬件和固件的跟踪.本文介绍了PSoC 4200DS主要特性,框图,以及原型板CY8CKIT-146PSoC 4200DS主要特性,电路图,材料清单,PCB设计图和装配图.

PSoC® 4 is a scalable and reconfigurable platform architecture for a family of programmable embedded system controllers with anARM® Cortex™-M0 CPU. It combines programmable and reconfigurable analog and digital blocks with flexible automatic routing. ThePSoC 4200DS product family, based on this platform architecture, is a combination of a microcontroller with digital programmablelogic, programmable interconnect, and standard communication and timing peripherals. The PSoC 4200DS products will be fullycompatible with members of the PSoC 4 platform for new applications and design needs. The programmable digital subsystem allowsflexibility and in-field tuning of the design.

The PSoC 4200DS devices include extensive support forprogramming, testing, debugging, and tracing both hardwareand firmware.The ARM Serial_Wire Debug (SWD) interface supports allprogramming and debug features of the device.

Complete debug-on-chip functionality enables full-devicedebugging in the final system using the standard productiondevice. It does not require special interfaces, debugging pods,simulators, or emulators. Only the standard programmingconnections are required to fully support debug.

The PSoC Creator Integrated Development Environment (IDE)provides fully integrated programming and debug support forPSoC 4200DS devices. The SWD interface is fully compatiblewith industry-standard third-party tools. The PSoC 4200DSfamily provides a level of security not possible with multi-chipapplication solutions or with microcontrollers. This is due to itsability to disable debug features, robust flash protection, andbecause it allows customer-proprietary functionality to be implementedin on-chip programmable blocks.

The debug circuits are enabled by default and can only bedisabled in firmware. If not enabled, the only way to re-enablethem is to erase the entire device, clear flash protection, andreprogram the device with new firmware that enables debugging.

Additionally, all device interfaces can be permanently disabled(device security) for applications concerned about phishingattacks due to a maliciously reprogrammed device or attempts todefeat security by starting and interrupting flash programmingsequences. Because all programming, debug, and test interfacesare disabled when maximum device security is enabled,PSoC 4200DS with device security enabled may not be returnedfor failure analysis. This is a trade-off the PSoC 4200DS allowsthe customer to make.

The CY8CKIT-146 PSoC 4200DS prototyping Kit is intended for use as a development platform forhardware or software in a laboratory environment. The board is an open system design, which doesnot include a shielded enclosure. This may cause interference to other electrical or electronicdevices in close proximity. In a domestic environment, this product may cause radio interference. Insuch cases, you may be required to take adequate preventive measures. In addition, this boardshould not be used near any medical equipment or RF devices.

Attaching additional wiring to this product or modifying the product operation from the factory defaultsettings may affect its performance and cause interference with other apparatus in the immediatevicinity. If such interference is detected, suitable mitigating measures should be taken.

The PSoC 4200DS Prototyping Kit, as shippedfrom the factory, has been verified to meet withrequirements of CE as a Class A product.
