Target Applications
Overview
The 8-bit MC9S08JM16 device further extends 
Freescale’s entry-level 8-bit embedded 
USB controller family with up to 16 KB of 
flash memory, a full-speed USB 2.0 device 
controller and an eight-channel, 12-bit  
analog-to-digital converter. The S08 JM family 
also has several system protection features, 
such as low voltage detection and a computer 
operating properly (COP) module. 
The MC9S08JM16 device is well suited  
for a variety of industrial control and  
consumer applications. Such applications 
include PC peripherals, industrial printers  
and touch panels. 
The MC9S08JM16 devices, like the other USB 
microcontrollers in the Controller Continuum, 
are supported by the Freescale USB-LITE 
Stack by CMX. This complimentary USB stack 
provides support for certain HID and CDC 
classes. Source code for the complimentary 
stack is available.
The MC9S08JM16 is software compatible 
with other devices in the Controller 
Continuum, providing a direct migration path 
to higher performing USB microcontrollers.

Features
Benefits
8-bit HCS08 Central Processing Unit (CPU)
•  Up to 24 MHz internal bus (48 MHz HCS08 
core) frequency offering 2.7 to 5.5V across 
temperature range of -40°C to +85°C
•  Offers strong performance throughout the entire 
voltage range
•  Support for up to 32 peripheral interrupt/
request resources
•  Allows for exceptional software flexibility and 
optimization for real-time applications
On-Chip Memory
•  Up to 16K flash read/program/erase over full 
operating voltage and temperature
•  Allows user to take full advantage of in-application, 
re-programmability benefits
•  Up to 1K RAM
•  Security circuitry to help prevent unauthorized  
access to RAM
•  Flash contents help to reduce system power 
consumption
•  256 Byte USB RAM
•  Improve data transfer speed by providing  
data buffering
Power-Saving Modes
•  Wait plus two stop modes
•  Allows continuation of sampling application in a reduced 
power state which reduces system power consumption
•  Multi-purpose clock generator (MCG)
•  Frequency-locked loop (FLL): Internal or external 
reference can be used to control the FLL
•  Phase-locked loop (PLL): Voltage controlled 
oscillator (VCO). Modulo VCO frequency divider.  
Lock detector with interrupt capability
•  Internal reference clock: Can be selected as the 
clock source for the MCU
•  External reference clock: Provides control for  
a separate crystal oscillator. Clock monitor with 
reset capability. Can be selected as the clock 
source for the MCU.
•  Reference divider provided
•  Clock source can be divided by 1, 2, 4 or 8
