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 Platform: |

Description: This sample displays a basic integer calculator powered
by the 8051 microcontroller. Although Keil C51 has a
full floating point math library the evaluation version
is restricted to 2k of object code, so we have constrained
this sample to integer maths in order to fit within this limit.
The program for this design was written in C using the
Keil uVision 2 IDE for which Proteus VSM provides
a Debug Monitor driver.
Instructions for configuring Proteus to run in conjunction
with the Keil environment can be found by editing the
8051 microcontroller on the schematic (point at it and
press CTRL-E) and then clicking on the help button
on the Edit Component dialogue form. Platform: |

Description: 基于CYPRESS CY7C68013 usb2.0的开发程序，该程序演示了访问IO的编写方法。-This directory contains the dev_io 8051 firmware
The purpose of this software is to demonstrate how
to use the buttons and LED on the EZ-USB developer s
kit.
The device I/O example program uses the LED on the Development board
to display a running application program on the EZ-USB chip.
The buttons on the development board may be pressed to count up (F3),
count down (F2), and reset the seven segment LED to "0" (F1) or "F" (F4).
The code is written in C and uses several EZ-USB library functions.
It does not use the FrameWorks.
The dev_io.hex file loads into internal memory.

Description: STC11/10xx系列单片机是宏晶科技设计生产的单时钟/机器周期(1T)的单片机，是高速、低功耗、超强干扰的新一代8051单片机，指令代码完全兼容传统8051，但速度快8-12倍。内部集成的FLASH寿命可达10万次，并且完全支持ISP和IAP功能。该系列针对不同功能、电压、封装等的型号规格非常齐全。所有的STC11/10xx系列单片机内部都固化了宏晶科技的ISP程序，不需要并行编程器，通过RS232串口就可以烧录用户程序。但一些系统为了程序保密或者采用其他诸如RS485通讯或其他通讯方式的需要，仍然需要自己编写ISP程序用于系统升级。在STC11/10xx系列单片机中以IAP打头的芯片型号，用户程序和数据FLASH是统一寻址，允许在用户程序中擦写FLASH，因此可以编写自己的ISP程序。
本程序例子中选用的单片机是IAP11F62X，包含内部可用的62kFLASH空间和扩展的1024字节XRAM。-STC11/10xx MCU is a macro technology design and production of single-crystal clock/machine cycle (1T) of the microcontroller, high-speed, low power, interference of a new generation of super-8051 microcontroller, instruction code is fully compatible with the traditional 8051, but the 8 speed-12 times. FLASH integrated within the life of up to 10 million, and fully support the ISP and IAP capabilities. The series for different functions, voltage, packaging model specification is complete. All STC11/10xx MCU are cured within a macro crystal technology, ISP program, does not require parallel programming device, can burn through the RS232 serial port on the user program. However, some systems used to process confidential or other communications such as RS485 or other communication needs, still need to write your own ISP program for system upgrades. In STC11/10xx MCU starts with the chip in order to IAP model, the user program and data addressing FLASH is unified, allowing users to program Platform: |
