Device Pin Assignments
The MAC7100 Family is available in 208-pin ball grid array (MAP BGA), 144-pin low profile quad flat
(LQFP), 112-pin LQFP, and 100-pin LQFP package options. The family of devices offer pin-compatible
packaged devices to assist with system development and accommodate a direct application enhancement
path. Refer to Table 2 for a comparison of the peripheral sets and package options for each device.
Most pins perform two or more functions, which are described in more detail in the MAC7100
Figure 22 show the pin assignments for various devices and packages.
