P89C58X2集成電路（IC）的微控制器規(guī)格書PDF中文資料

DESCRIPTION

The Philips microcontrollers described in this data sheet are high-performance static 80C51 designs. They are manufactured in an advanced CMOS process and contain a non-volatile Flash program memory. They support both 12-clock and 6-clock operation.
