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 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.

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

The MC9S08JM16 is software compatible

with other devices in the Controller

Continuum, providing a direct migration path

to higher performing USB microcontrollers.

• 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

Peripherals

• USB device module

•

Full-speed USB 2.0 (12 Mbps) module with

dedicated on-chip 3.3V regulator

Supports control, interrupt, isochronous and

bulk transfers

• Output formatted in 12-, 10- or 8-bit

right-justiﬁed format

• Single or continuous conversion

• Operation in low-power modes for lower

noise operation

Cost-Effective Development Tools

DEMO9S08JM16

$79ꢀUSD*ꢀ

• Asynchronous clock source for lower

noise operation

Cost-effective demonstration kit featuring

the JM16 daughter card. Support for USB

full speed device. Built-in USB-BDM

circuitry is available for debugging and

programming, serial communication, and

simple logic analyzer.

• Two serial communications interface

(SCI) modules offering asynchronous

communications

• Provides standard UART communications

peripheral

• Allows full-duplex, asynchronous, NRZ serial

communication between MCU and remote devices

• I C with up to 100 kbps with maximum bus

• Ability to add an additional I C device

loading; multi-master operation; programmable

slave address; interrupt driven byte-by-byte

data transfer; supports broadcast mode and

10-bit addressing

DC9S08JM16

$10ꢀUSD*ꢀ

The JM16 daughter card can also be ordered

independently to use on the DEMOJM

demonstration kit.

• SPI—Two serial peripheral interfaces with

full-duplex or single-wire bidirectional; double-

buffered transmit and receive; master or slave

mode; MSB-ﬁrst or LSB-ﬁrst shifting

• Having two SPI allows two separate dedicated

devices, for example, one SPI dedicated to a

ZigBee transceiver, and the other to MCUs or

peripherals

• Timer pulse width modulation (TPM)—Up to

six channels

• Each channel may be input capture, output

compare or edge-aligned PWM

• Input capture trigger on either rising or falling edge

• Selectable polarity on PWM outputs

CodeWarrior Development Studio

for Microcontrollers 6.1

• Timer clock source selectable as prescaled bus

clock, ﬁxed system clock or an external clock pin

Complimentary**ꢀꢀ

CodeWarrior Development Studio for

Microcontrollers is an integrated tool suite

that supports software development for

Freescale’s 8-bit or 32-bit microcontrollers.

Designers can further accelerate application

development with the help of the Processor

Expert™ tool, which is an award-winning

rapid application development tool in the

CodeWarrior tool suite.

Input/Output

• Up to seven Keyboard Interrupt (KBI) pins with • Each KBI pin is programmable as falling edge only,

selectable polarity

rising edge only, falling edge and low level, or rising

edge and high level interrupt sensitivity

• 37 general purpose input/output (GPIO)s

• Results in a large number of ﬂexible I/O pins that

allow vendors to easily interface the device into

their own designs

System Protection

• Watchdog computer operating properly (COP)

reset with option to run from dedicated 1 kHz

internal clock source or bus clock

• Allows the device to recognize run-away code

(inﬁnite loops) and resets the processor to help

avoid lock-up states

Freescale USB-LITE Stack by CMX

Complimentary**

• Low-voltage detection with reset or interrupt;

selectable trip points

• Alerts the developer to voltage drops outside of the

typical operating range

• Illegal op code detection with reset

• Allows the device to recognize erroneous code and

resets the processor to help avoid lock-up states

Freescale is providing a comprehensive USB

software solution through a complimentary

USB stack. Freescale USB-LITE Stack by

CMX enables USB device modes of operation.

The USB stack supports several HID and CDC

to UART projects. The complimentary stack

also interfaces with CodeWarrior Development

Studio, providing a productive, comprehensive

development environment for designing

embedded applications.

• Flash block protection

• Prevents unauthorized access to ﬂash RAM which

greatly reduces the chance of losing vital system

code for vendor applications

Hardware Development Support

• Single-wire background debug interface

• This allows developers to use the same interface

for multiple platforms

• Breakpoint capability

• Allows single breakpoint setting during in-circuit

debugging (plus two more breakpoints in on-chip

debug module)

• On-chip in-circuit emulator (ICE) debug

module (containing three comparators and

nine trigger modes). Eight deep FIFO for

storing change-of-ﬂow addresses and

event-only data, debug module supports

both tag and force breakpoints.

• Grants full access to built-in chip emulation without

the added expense of traditional emulator hardware
