The liquid crystal electrical degree of new single-phase antidistorting measures the integrated circuit
Little electronics corporation (austriamicrosystems) of Austria Announce, measure the introduction of the integrated circuit with the single-phase system level chip of the built-in flashing memory, 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.
Little industry and medical marketing of electronics corporation of Austria are in charge of Matjaz Novak to represent: "The chip has adopted the little flashing memory technology of electronics corporation in extremely reliable Austria, guarantee the products have instrument trades on the system level chip unprecedented procedure and data keep the characteristic. In addition, flashing memory, speaking from the design, below zero 40& ordm on the scene; C has 125& ordm to zero; Run in the wide temperature range of C, and prove through practice. "
The little instrument products of electronics corporation in Austria employ the manager Dave Simpson to say: "AS8268 measures the outstanding accurate characteristic that the forward end has, reflect on the repeatable precision of invariable invariable measurement that this device offers. The conformance setting-up that this kind of measurement is on the technological foundation of analog front end that the little electronics corporation is proved by the trade in Austria, and all met the requirement of the tightest and severest public service in design and manufacture. "
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. It input through being multi-functional /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, 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.
