New 5 stitches of microprocessors that ST introduces 25 built-in watchdogs reset IC
Purpose law semiconductor (ST) Introduce 25 industrial standards and reset the monitor IC today, these new products have already reached the production requirement now, because of adopting the manufacture procedure of innovation, the time of preparation of delivery of the new product shortens to 3 weeks, and other manufacturers usually take 12 weeks or more long processing and equipment time. These products have five kinds of basic circuit configurations in all, each kind of disposition has five kinds of voltage that select, so there are 25 kinds of different Item Models in all. Restored to the throne the threshold and pressed including 2.63V, 2.93V, 3.08V, 4.40V and 4.65V (representative value) effectively . Product performance includes reset input of button, watchdog and low state are effective or the high state is reset and exported effectively. STM6821 is furnished with reset input of button, watchdog and high state to reset and export effectively, STM6823 allocates the low state to reset and export effectively, other characteristics are the same as STM6821; STM6824 has a low states that is reset and exported effectively too, but without reset input, that a high state is reset and exported effectively; STM6825 increases a high state to reset and export effectively too, but there is no watchdog's function; Finally, STM6321 is as the same as STM6824, but increase a open circuit drain to export in the valid low state resets the pin. These products will increase two kinds of dispositions more later, each kind of disposition has five kinds of voltage that select, the Item Model will increase to 35 kinds; Will also increase in seven kinds of circuit configurations by a 2.5V voltage and select, there will be 42 kinds of different products types when the time comes. These products are suitable for needing to monitor the application of the function in any, for example: Medical equipment, metrical instrument, server, ADSL, cash register, car products, instrument and commercial installation. Each kind of disposition includes fundamental supervisory functions such as the monitoring system power and making the systematic processor reset when the voltage is lower than allowable value,etc.. Selected the watchdog that holds ' Such as STM6821 products) Used in the protection system, prevent the software from being distorted. Manual reset input is a very popular function, very useful at the integrated stage of system development. It is effective that there are high states and low state actual output, in addition, open a way the drain is exported, these reset the monitor and is suitable for any microprocessor or one-chip computer application. Chip these adopt one lead-free SOT-23 capsulate, operating temperature range within the intersection of industry and temperature range (40 to 85 ℃) ,The intersection of pin and 100% compatible products that industry use extensively at present of product these, may direct insert substitute existing product. ST offers the sample wafers of all products now, all products have already begun the medium-sized scale to make, the wholesale price of the products is every film of 0.23 dollars.
