SH79F0819 Overview

SH79F0819 8051 microcontroller with 10-bit ADC

Features

• SH79F0819 is a high-speed and high-efficiency 8051 compatible microcontroller. It has the superior feature of running faster than the traditional 8051 chip at the same oscillation frequency. SH79F0819 retains most of the features of the standard 8051 chip. These features include built-in 256-byte RAM, 1 UART and external interrupts INT2 and INT3. In addition, SH79F0819 also integrates external 256-byte RAM, 4 16-bit timers/counters (Timer2 - Timer5). The microcontroller also includes an 8K-byte Flash block suitable for programs and data. SH79F0819 integrates not only standard communication modules such as EUART, but also LCD driver, ADC with built-in comparison function, PWM timer and other modules.


• To achieve high reliability and low power consumption, SH79F0819 has built-in watchdog timer, low voltage reset function and system clock monitoring function. In addition, SH79F0819 also provides 2 low power saving modes.

概述
SH79F0819是一种高速高效率8051可兼容单片机。
在同样振荡频率下,
较之传统的8051芯片它有着运行更快速的优越特性。
SH79F0819保留了标准8051芯片的大部分特性。这些特性包括内½256字节RAM,1个UART和外½中断INT2和INT3。此
外,SH79F0819还集成了外部256字节RAM,4个16½定时器/计数器(Timer2
- Timer5)。该单片机还包括适合于程序和数据
的8K字节Flash块。
SH79F0819不仅集成了如EUART等标准通讯模块,此外还集成了LCD驱动器,具有内建比较功½的ADC,PWM定时器等
模块。
为了达到高可靠性和½功耗,SH79F0819内建看门狗定时器,½电压复½功½及系统时钟监控功½。此外SH79F0819还提
供了2种½功耗省电模式。
