General Description The SH79F642B is a low-cost,high-performance single-phase energy metering SOC chip, and integrated single-phase energy metering, LCD driver, Calendar clock and enhanced 8051 microcontroller. SH79F642B embedded energy metering module, to measure active, reactive and apparent energy, as well as voltage/ current rms. And then to monitor the voltage sag of the power line and zero-crossing features. The SH79F642B is a fast 8051 compatible micro-controller with a redesigned CPU of no wasted clock and memory cycles. Typically, it will be faster and exhibit better performance than the traditional 8051 at the same oscillator frequency. The SH79F642B retains most features of the standard 8051. These features include internal 256 bytes RAM, two 16-bit timers / counters, three UART, and external interrupt INT1. In addition, the SH79F642B provides external 2816 bytes RAM (not include LCD RAM), two 12-bit PWM outputs, external interrupt INT2&3, 16-bit timer/counter (Timer2) compatible with 8052. It contains a 64K Bytes Flash memory block for program and data. Some standard serial communication modes such as EUART、IR are supported in SH79F642B. Also the LCD driver, ADC,PWM Timer and RTC are incorporated in SH79F642B. For high reliability and low cost issues, the SH79F642B builds in PLL clock, LCD Driver, Watchdog Timer, Low Voltage Reset function, and oscillator fail detection. SH79F642B also supports two power supply modes and two power saving modes to reduce power consumption. 1 V2.0 PDF Документация на серию SH79F642B 79F161 V0.2 Keywords: Дата модификации: 27.05.2022 Размер: 1.92 Мб 157 стр. найти SH79F642BS/064SR.pdf Внимание!
