S08MM: Flexis 8-bit MCUs<br />
The 9S08MM128/64/32 provides ultra-lowpower<br />
operation, USB connectivity, graphic<br />
display support and unparalleled measurement<br />
accuracy, all in a single 8-bit MCU, allowing<br />
device designers to create more fully featured<br />
products at a lower cost. It is ideal for<br />
applications requiring a significant amount of<br />
precision analog.<br />
