HXE12P01B

 Single-phase Energy Metering IC integrated LCD driver and enhanced 8051 Microcontroller

» Description 

The HXE12P01B 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.

The HXE12P01B 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 HXE12P01B 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 HXE12P01B retains most features of the standard 8051. These features include internal 256 bytes RAM, two 16-bit timers / counters, three UART, and external interrupt INT0, INT1. In addition, the HXE12P01B 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 HXE12P01B. Also the LCD driver, ADC and RTC are incorporated in HXE12P01B.

For high reliability and low cost issues, the HXE12P01B builds in PLL clock, Watchdog Timer, Low Voltage Reset function, and oscillator fail detection. G80F925 also supports two power supply modes and three power saving modes to reduce powerconsumption.
