ST72T91L Features

* an enhanced instruction set. Oscillator frequency may be as high as 8MHz, however, thanks to the fully static design, operation is possible down to DC. Under software control, the ST7291L may be placed in either WAIT or HALT modes, thus reducing power consumption. Figure 2. ST7291L Block Diagram The
