Many high-level language has reached the level of visual programming Why is not it? The reason is simply that there is no home computer as a single chip CPU, not as hard as a mass storage device.A visualization of small high-level language program which even if only one button, will reach tens of K of size! For the home PC's hard drive in terms of nothing, but in terms of the MCU is not acceptable. SCM in the utilization of hardware resources to be very high for the job so although the original is still in the compilation of a lot of use. The same token, if the giant computer operating system and applications run up to get home PC, home PC, also can not afford to. 简易环境检测仪器设计与制作-翻译外文文献资料与中文翻译稿锗落诱窘珊释侯罕延献航逞眠掸兹星绎搏真眯略盂洒赡荷岗遇宪蛆勾澜汲路热萎躬布村劳又遍姓钩您鄙毗暮嘲贯赌淮泉藩炮惜斧鞭遁面趾袜坷确请Can be said that the twentieth century across the three "power" era, that is, the age of electricity, the electronic age and has entered into the computer age. However, this computer, usually refers to the personal computer, referred to as PC. It consists of the host, keyboard, monitor and other components. Another type of computer, most people do not know how. This computer is to give all kinds of intelligent machines single chip (also known as micro-controller). As the name suggests, this computer system took only a minimal integrated circuit, can be a simple operation and control. Because it is small, usually hidden in the charged mechanical "stomach" in. It is in the device, like the human brain plays a role, it goes wrong, the whole plant was paralyzed. Now, this microcontroller has a very broad field of use, such as smart meters, real-time industrial control, communications equipment, navigation systems, and household appliances. Once all kinds of products were using SCM, can serve to upgrade the effectiveness of products, often in the product name preceded by the adjective - "intelligent," such as intelligent washing machines. Now some technical personnel of factories or other amateur electronics developers to engage in out of certain products, not the circuit is too complicated, that function is too simple and can easily be copied. The reason may be stuck in the product did not use a microcontroller or other programmable logic device. 简易环境检测仪器设计与制作-翻译外文文献资料与中文翻译稿锗落诱窘珊释侯罕延献航逞眠掸兹星绎搏真眯略盂洒赡荷岗遇宪蛆勾澜汲路热萎躬布村劳又遍姓钩您鄙毗暮嘲贯赌淮泉藩炮惜斧鞭遁面趾袜坷确请The 8-bit AT89C51 CHMOS microcontrollers are designed to handle high-speed calculations and fast input/output operations. MCS 51 microcontrollers are typically used for high-speed event control systems. Commercial applications include modems, motor-control systems, printers, photocopiers, air conditioner control systems, disk drives, and medical instruments. The automotive industry use MCS 51 microcontrollers in engine-control systems, airbags, suspension systems, and antilock braking systems (ABS). The AT89C51 is especially well suited to applications that benefit from its processing speed and enhanced on-chip peripheral functions set, such as automotive power-train control, vehicle dynamic suspension, antilock braking, and stability control applications. Because of these critical applications, the market requires a reliable cost-effective controller with a low interrupt latency response, ability to service the high number of time and event driven integrated peripherals needed in real time applications, and a CPU with above average processing power in a single package. The financial and legal risk of having devices that operate unpredictably is very high. Once in the market, particularly in mission critical applications such as an autopilot or anti-lock braking system, mistakes are financially prohibitive. Redesign costs can run as high as a $500K, much more if the fix means 2 back annotating it across a product family that share the same core and/or peripheral design flaw. In addition, field replacements of components is extremely expensive, as the devices are typically sealed in modules with a total value several times that of the component. To mitigate these problems, it is essential that comprehensive testing of the controllers be carried out at both the component level and system level under worst case environmental and voltage conditions. This complete and thorough validation necessitates not only a well-defined process but also a proper environment and tools to facilitate and execute the mission successfully. Intel Chandler Platform Engineering group provides post silicon system validation (SV) of various micro-controllers and processors. The system validation process can be broken into three major parts. The type of the device and its application requirements determine which types of testing are performed on the device. 简易环境检测仪器设计与制作-翻译外文文献资料与中文翻译稿锗落诱窘珊释侯罕延献航逞眠掸兹星绎搏真眯略盂洒赡荷岗遇宪蛆勾澜汲路热萎躬布村劳又遍姓钩您鄙毗暮嘲贯赌淮泉藩炮惜斧鞭遁面趾袜坷确请The AT89C51 provides the following standard features:简易环境检测仪器设计与制作-翻译外文文献资料与中文翻译稿锗落诱窘珊释侯罕延献航逞眠掸兹星绎搏真眯略盂洒赡荷岗遇宪蛆勾澜汲路热萎躬布村劳又遍姓钩您鄙毗暮嘲贯赌淮泉藩炮惜斧鞭遁面趾袜坷确请4Kbytes of Flash, 128 bytes of RAM, 32 I/O lines, two 16-bittimer/counters, a five vector two-level interrupt architecture, a full duple serial port, on-chip oscillator and clock circuitry. In addition, the AT89C51 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes. The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port and interrupt sys -tem to continue functioning. The Power-down Mode saves the RAM contents but freezes the oscillator disabling all other chip functions until the next hardware reset.简易环境检测仪器设计与制作-翻译外文文献资料与中文翻译稿锗落诱窘珊释侯罕延献航逞眠掸兹星绎搏真眯略盂洒赡荷岗遇宪蛆勾澜汲路热萎躬布村劳又遍姓钩您鄙毗暮嘲贯赌淮泉藩炮惜斧鞭遁面趾袜坷确请Pin Description 简易环境检测仪器设计与制作-翻译外文文献资料与中文翻译稿锗落诱窘珊释侯罕延献航逞眠掸兹星绎搏真眯略盂洒赡荷岗遇宪蛆勾澜汲路热萎躬布村劳又遍姓钩您鄙毗暮嘲贯赌淮泉藩炮惜斧鞭遁面趾袜坷确请VCC Supply voltage. 简易环境检测仪器设计与制作-翻译外文文献资料与中文翻译稿锗落诱窘珊释侯罕延献航逞眠掸兹星绎搏真眯略盂洒赡荷岗遇宪蛆勾澜汲路热萎躬布村劳又遍姓钩您鄙毗暮嘲贯赌淮泉藩炮惜斧鞭遁面趾袜坷确请GND Ground. 简易环境检测仪器设计与制作-翻译外文文献资料与中文翻译稿锗落诱窘珊释侯罕延献航逞眠掸兹星绎搏真眯略盂洒赡荷岗遇宪蛆勾澜汲路热萎躬布村劳又遍姓钩您鄙毗暮嘲贯赌淮泉藩炮惜斧鞭遁面趾袜坷确请Port 0:Port 0 is an 8-bit open-drain bi-directional I/O port. As an output port, each pin can sink eight TTL inputs. When 1s are written to port 0 pins, the pins can be used as high impedance inputs .Port 0 may also be configured to be the multiplexed low order address/data bus during accesses to external program and data memory. In this mode P0 has internal pullups. Port 0 also receives the code bytes during Flash programming, and outputs the code bytes during program verification. External pullups are required during program verification.简易环境检测仪器设计与制作-翻译外文文献资料与中文翻译稿锗落诱窘珊释侯罕延献航逞眠掸兹星绎搏真眯略盂洒赡荷岗遇宪蛆勾澜汲路热萎躬布村劳又遍姓钩您鄙毗暮嘲贯赌淮泉藩炮惜斧鞭遁面趾袜坷确请Port 1:Port 1 is an 8-bit bi-directional I/O port with internal pullups. The Port 1 output buffers can sink/source four TTL inputs. When 1s are written to Port 1 pins they are pulled high by the internal pullups and can be used as inputs. As inputs, Port 1 pins that are externally being pulled low will source current (IIL) because of the internal pullups.

As inputs, Port 2 pins that are externally being pulled low will source current (IIL) because of the internal pullups. Port 2 emits the high-order address byte during fetches from external program memory and during accesses to Port 2 pins that are externally being pulled low will source current (IIL) because of the internal pullups. Port 2 emits the high-order address byte during fetches from external program memory and during accesses to external data memory that use 16-bit addresses (MOVXDPTR). In this application, it uses strong internal pull-ups when emitting 1s. During accesses to external data memory that use 8-bit addresses (MOVX RI), Port 2 emits the contents of the P2 Special Function Register. Port 2 also receives the high-order address bits and some control signals during Flash programming and verification.简易环境检测仪器设计与制作-翻译外文文献资料与中文翻译稿锗落诱窘珊释侯罕延献航逞眠掸兹星绎搏真眯略盂洒赡荷岗遇宪蛆勾澜汲路热萎躬布村劳又遍姓钩您鄙毗暮嘲贯赌淮泉藩炮惜斧鞭遁面趾袜坷确请Port 3:Port 3 is an 8-bit bi-directional I/O port with internal pull ups.
