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