Description: 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
