[Other] 单片机优化设计 DL : 0: 21IC精华帖之单片机优化设计原文片断：单片机程序的设计、仿真调试只是单片机系统的设计一部分，单片机系统的优化设计才是单片机系统的设计的核心和难点。由于很多人没有认识到这个问题，导致了单片机系统不能工作、或是工作不稳定、成本过高等问题。 -21IC essence TIE Zhi microcontroller design optimization original clips : SCM process design, simulation, debugging MCU is part of the design system, SCM System Design Optimization of SCM system is the core of the design and difficult. Because many people do not realize that the problem led to the SCM system can not work, or job insecurity, high costs and other issues.

[Other] w78e51bcn DL : 0: W78E51B 规格书 W78E51B 是宽频率范围、低功耗的8 位微控制器。它的指令集同标准8051 指令集完全兼容。W78E51B 包含4K 字节的Flash EPROM；128 字节的RAM；4 个8 位双向、可位寻址的I/O 口；一个附加的4 位 I/O 口P4；2 个16 位定时/计数器；一个硬件Watchdog 定时器及一个串行口。这些外围设备都由有7 个中断源和2 级中断能力的中断系统支持。为了方便用户进行编程和验证，W78E51B 内含的Flash EPROM 允许电编程和电读写。一旦代码确定后，用户就可以对代码进行保护。 W78E51B 有2 种节电模式，空闲模式和掉电模式，2 种模式均可由软件来控制选择。空闲模式下，处理器时钟被关闭，但外设仍继续工作。在掉电模式下晶体振荡器停止工作，以将功耗降至最低。外部时钟可以在任何时间及状态下被关闭，而不影响处理器运行。-W78E51B specifications W78E51B is broadband rates, low-power 8-bit microcontroller. Its instruction set with the standard 8051 instruction set compatible. W78E51B contains 4K bytes of Flash EPROM; 128 bytes of RAM; Four eight two-way, the bit addressable I / O port; An additional four I / O P4; Two 16-bit timer / counter; A hardware Watchdog timer and a serial port. These external equipment by a seven interrupt source and two interrupts the interruption system. For the convenience of users and certification program, W78E51B intron Flash EPROM programming and allow -- -- literacy. Once the code is finalized, users will be able to source protection. W78E51B are two kinds of power saving mode, idle mode and power down mode, the two models can be controlled by the software to choose. Idle mode
