Device Overview
1.1 Introduction
MC9S08JS16 series MCUs 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.
NOTE
The only difference between MC9S08JS16/MC9S08JS8 and
MC9S08JS16L/MC9S08JS8L is that MC9S08JS16 and MC9S08JS8
support USB bootloader function with voltage above 3.9 V while
MC9S08JS16L and MC9S08JS8L support USB bootloader function at
3.3 V.
Disable internal USB voltage regulator and apply 3.3 V to the V
USB33
pin
when using MC9S08JS16L and MC9S08JS8L for the USB bootloader
function.
Table 1-1 summarizes the peripheral availability per package type for the devices available in the
MC9S08JS16 series.
