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.
