1.4 MC9S08AW60

The MC9S08AW60, MC9S08AW48, MC9S08AW32, and MC9S08AW16 are members of the low-cost,

high-performance HCS08 family of 8-bit microcontroller units (MCUs). All MCUs in the family use the

enhanced HCS08 core and are available with a variety of modules, memory sizes, memory types, and

package types. Refer to Table 1-1 for memory sizes and package types.

Table 1-2 summarizes the peripheral availability per package type for the devices available in the

MC9S08AW60/48/32/16 series.
