cypress公司的PSOC 4700S是可编程片上系统(PSoC),集成了ARM® Cortex®-M0+ CPU,包括了可编程和可配置的模拟和数字区块,并具有灵活的自动走线.广泛支持编程,测试,调试,以及跟踪硬件和固件.32位MCU子系统48MHz,多达32KB闪存和多达4KB SRAM,可进行电容检测,电感检测支持16个传感器,主要用在消费类电子,汽车电子,工业领域.本文介绍了PSOC 4700S主要特性,框图,以及PSoC® 4700S电感检测评估板CY8CKIT-148主要特性,框图和电路图.

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 4700S product family, based on this platform, is the industry’s first microcontroller with inductive sensing and capacitive sensingtechnology in a single chip. The inductive sensing (MagSense™) technology enables sensing of metal objects and industry’s leadingcapacitive sensing (CapSense®) technology enables sensing of non-metallic objects.

PSoC 4700S 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 IDE provides fully integrated programmingand debug support for the PSoC 4700S devices. The SWDinterface is fully compatible with industry-standard third-partytools. The PSoC 4700S family provides a level of security notpossible with multi-chip application solutions or withmicrocontrollers. It has the following advantages:

■ Allows disabling of debug features
■ Robust flash protection
■ Allows customer-proprietary functionality to be implemented inon-chip programmable blocks

The debug circuits are enabled by default and can be disabledin firmware. If they are 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.

Thus firmware control of debugging cannot be over-riddenwithout erasing the firmware thus providing security.

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. All programming, debug, and test interfaces aredisabled when maximum device security is enabled.Therefore,PSoC 4700S, with device security enabled, may not be returnedfor failure analysis. This is a trade-off the PSoC 4700S allows thecustomer to make
