SH79F0819 Datasheet – 8051 Microcontroller with 10bit ADC
Enhanced 8051 Microcontroller with 10bit ADC
SH79F0819 overview
The SH79F0819 is an Enhanced 8051 Microcontroller with 10bit ADC made by Sino Wealth, supplied in an SOP28L Pin Type package. The absolute maximum ratings table on this page lists the 4 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the SH79F0819 pinout and maximum ratings, with the full datasheet PDF to preview below or download.
The SH79F0819 is a high performance 8051 compatible micro-controller, regard to its build-in Pipe-line instruction fetch structure, that helps the SH79F0819 can perform more fast operation speed and higher calculation performance, if compare SH79F0819 with standard 8051 at same clock speed.
The SH79F0819 retains most features of the standard 8051. These features include internal 256 bytes RAM, UART and Int2-3.In addition, the SH79F0819 provides external 256 bytes RAM, It also contains four 16-bit timer/counter (Timer2 - Timer5) and 8K bytes Flash memory block both for program and data. Also the ADC and PWM timer functions are incorporated in SH79F0819. For high reliability and low power consumption, the SH79F0819 builds in Watchdog Timer, Low Voltage Reset function and SCM function. And SH79F0819 also supports two power saving modes to reduce power consumption
