ml22p80x

In the assortment of company oki electric industry appeared a new series of the large-scale integrated circuits (BIS, LSI), intended for equipping the constructions with the function of synthesis vocal communications. The special feature of the new product which received designation ML22P80X, is the presence of the programmed memory. This gives the possibility to write vocal data in the microcircuit in that stage when it is inslatted in the finished product.

Why can be required the possibility of programming vocal data? For example, with the production of limited party of instruments, when the order of the party mask microcircuits is economically not justified. At the same time, the use of a external memory leads to the complication of project and can raise the price . Furthermore, because of the possibility of programming, the method of adaptation of one and same instrument under the special features of specific operating conditions appears.

In the microcircuits series ML22P80X, besides memory, are located all the remaining units, necessary for constructing the final systems, including analog chains. Into a series ML22P80X entered three product: ML22P802 (volume of memory â€“ 2 Mbit), ML22P804 (4 Mbit) and ML22P808 (8 Mbit). Let us recall, thar last represented series ML2280X, which also includes three microcircuits with memory of different volume. In ML2280X is used the memory, programmed under production conditions (P2ROM, Production programmed ROM), whose advantage consists in shortening the delivery times of the custom-made modifications microcircuits.
