DCS can not only complete the functions of the original analog instrument, but also greatly surpass the analog instrument. This is because it adopts advanced computer technology, communication technology, CRT technology, and control technology such as 4C technology. After adopting digital control, the algorithms stored in the controller in ROM can be said to be infinite, and each algorithm represents a function. These functions are implemented in analog instruments using analog circuits, which are limited by the drift, resistance, capacitance, and other devices of the analog circuits. It is expensive, even almost impossible, to make a high-precision analog instrument. The algorithm of digital control is implemented through programming. Replace the functions that analog circuits can achieve with programs. In theory, it is infinite, which is a great progress. The principle is the same for various DCS systems. Usually referred to as functional blocks for various algorithms. The assembly of functional blocks is called the functional block library.
The KinetisE series is one of the choices for smart home applications. The KinetisE series 32-bit MCU is a highly scalable ARMCortex-M0+core MCU product, which has won market praise for its low power consumption characteristics. The KinetisE series has strong system electromagnetic noise immunity (previously only 8-bit and 16-bit MCUs had the same level of capability), making it an ideal choice for white goods (such as dishwashers, refrigerators), industrial applications, home and building control systems, motor controlled fans, industrial converters, and other applications typically operating in high noise environments. The KinetisE series offers a wide range of memory, peripherals, and product packages to choose from. They have a universal number of peripherals and pins, allowing developers to easily migrate within the same MCU family or between multiple MCU families to utilize more memory or feature integration. This scalability enables developers to standardize their terminal product platforms on the KinetisE series, maximize hardware and software reuse, and shorten the time required for product launch.
The KinetisE series power management module (PMC) provides three power modes: run, wait, and stop, which can operate while ensuring energy efficiency. The built-in watchdog and programmable CRC module, with a 64 bit unique identification code (ID) per chip, provide higher security.
The KinetisL series of devices is also a highly distinctive MCU product of Freescale, with low power consumption and excellent energy efficiency characteristics that can provide perfect human-machine interaction control and management. With this series of MCUs, even for applications with very strict energy consumption requirements, designers do not have to be limited to using only 8-bit and 16-bit MCUs due to power consumption limitations. KinetisL provides a variety of flexible ultra-low power consumption modes, suitable for different application situations, and maximizes battery life; Its energy-saving architecture uses a variety of technologies to optimize power consumption, including 90nm thin film storage (TFS) technology, clock and power gating technology, as well as an efficient platform with a bit processing engine (BME), a peripheral crossbar, and a zero wait flash memory controller. In addition, energy-saving peripherals enable intelligent peripheral functions in deep sleep mode, allowing for intelligent decision-making and data processing without awakening the kernel. At the same time, this series has optimized dynamic and stop current capabilities and provides excellent processing performance. It also offers a variety of on-chip flash density, as well as a rich selection of analog modules, connection functions, and HMI peripherals.
