What AS8268 still can satisfy public utility is all prevent distort requirement, the LCD that can deploy a client to set displays screen. The appearance that is based on AS8268 requires few exterior element only, from go up at all the dependability that improved appearance, reduced the cost of meter system.
AS8268 is compositive all function module that single-phase report spends metric place to ask, the report that includes precision is spent measure front, of a 8 microprocessor, 32kB piece go up shine put, 96 paragraphs of real time clock, liquid crystal display screen (any LCD) drive circuit, interface that can satisfy a client to appoint and 12 of indication requirement can process designing, and piece go up temperature sensor.
AS8268 still offerred the exterior EEPROM of use 2-32KB to save the solution of data, can combine complete programmable occupation standard 8 8051 compatible microprocessor (of MCU) and 32kB piece on shine put. In addition, it still deployed two general-purpose asynchronous receives transmitter (so that UART) has exterior news report. Connect overmuch function to input / a certain end in outputting end, can show pulse of programmable energy LED is outputted. This kind of accurate output and piece on pulse tally is united in wedlock, can offer the choice program that digitlizes calibration automatically quickly. The real time clock of 1.4ppm of the ± on chip / calendar (RTC) contains two to call the police register and reserve batteries, can use at much cost to lead the design that electric energy expresses, still can use piece on temperature sensor raises clock precision through temperature compensation.
The digital signal processor in chip interior (inside DSP) , voltage of energy of have rendered great service, main circuit and main circuit electric current all can be calculated directly. Adopt the applied program that him user writes, also can come true to inspect the computation in power to be being mixed without result power.
AS8268 uses the 64 LQFP that cite a base to enclose, have the compatibility that brings a foot to go up with the AS8218 that supplies currently and AS8228 product. AS8268 sample but 2007 the 2nd quarter is offerred.
