The Austrian microelectronics introduces the liquid crystal electrical degree of new single-phase antidistorting and measures the integrated circuit
Austria little electronics corporation claim until built-in single-phase system level chip of flashing memory measure the introduction of the integrated circuit, the electric meter integrated circuit product series of the company add a new product - AS8268 again. AS8268 has offered the Integrated system level chip solution for display instrument of the liquid crystal, and through the Built-in: high-performance flashing memory of the system, have offered safe procedure and data.
AS8268 still can meet all antidistorting requirements of the public service, and can allocate LCD display screen that the customer stipulate. The outside component that the instrument based on AS8268 only needs to be few, has improved the reliability of the instrument fundamentally, and reduced the cost of the instrumental system.
AS8268 has integrated single-phase electrical degree and measured all required function module, including delicate electrical degree measure forward end, 1 8 microprocessor, flashing memory, real time clock, 96 sections of liquid crystal displays (LCD) at the block of 32kB Any interface which driving circuit, satisfiable customer appointed and revealing programmable multi-functional I/O of 12 routes of the requirement, and the temperature sensor on slice.
AS8268 has offered and kept the machine format solution with outside EEPROM of 2- 32 KB, and can combine 8 8051 compatible microprocessors (MCU) of totally programming sector standard And the flashing memory on scene of 32kB. In addition it allocate two piece general to receive sender (UART) while being asynchronous also In order to carry on the external communication. Through being multi-functional to input /end at Ausgang,can last energy LED pulse outputs programming. This kind of precision is exported and combined with impulse counter on scene, can offer the fast automatic digitized calibrated selection scheme. On the chip? Real time clock / calendar of 1.4ppm There are two warning registers and stand-by batteries, the design used for many rate electric energy meters, it can utilize on slice the temperature sensor improve the clock precision by temperature compensation.
Digital signal processor (DSP) within the chip Inside,whose name is meritorious energy, it is main for circuit voltage and main circuit electric current can direct calculation. Through the utility program that users wrote, can also realize the calculation of reactive power and apparent power.
AS8268 adopts 64 pins LQFP to capsulate, possesses the compatibility on the pin with AS8218 and AS8228 products that are supplied at present. AS8268 sample can be offered in the 2nd quarter of 2007.
