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

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

? Support for up to 32 peripheral interrupt/

request resources

On-Chip Memory

? Up to 16K flash read/program/erase over full

operating voltage and temperature

? Up to 1K RAM

? 256 Byte USB RAM

Power-Saving Modes

? Wait plus two stop modes

? Multi-purpose clock generator (MCG)

Peripherals

? USB device module

Benefits

? Offers strong performance throughout the entire

voltage range

? Allows for exceptional software flexibility and

optimization for real-time applications

? Allows user to take full advantage of in-application,

re-programmability benefits

? Security circuitry to help prevent unauthorized

access to RAM

? Flash contents help to reduce system power

consumption

? Improve data transfer speed by providing

data buffering

? Allows continuation of sampling application in a reduced

power state which reduces system power consumption

? 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

? Full-speed USB 2.0 (12 Mbps) module with

dedicated on-chip 3.3V regulator

? Supports control, interrupt, isochronous and

bulk transfers
