The MM256/128 devices, like other USB
microcontrollers in Freescale’s Controller
Continuum, are supported by the medical
applications USB stack. This complimentary
USB stack provides support for several
classes, including MSD, HID, CDC and
Personal Healthcare Device Class (PHDC),
while the Medical Connectivity Library enables
inter-device communication (IEEE 11073
compliant). Additionally, Freescale’s MQX
software enables real-time operating system
(RTOS) functionality and a USB stack.
Freescale’s Tower System provides the user
with a modular, reconfigurable demonstration
and development platform. The MM quick
peripheral user guides and application notes
have been developed to save development
time while building their own application. The
MCF51MM256/128 is part of the Freescale
Flexis microcontroller series. The Flexis series

Development Tools
TWR-MCF51MM-KIT
The TWR-MCF51MM-KIT is a full featured
modular development platform using the
Freescale Tower System that allows for quick
code development and easy prototyping.
The standard kit includes the following
components:
• TWR-MCF51MM: A standalone development
board featuring the MCF51MM256VLL
microcontroller.
• TWR-SER: A serial connectivity board to that
supports both USB and RS232.
• TWR-ELEV: Two (2) elevator boards to
connect the MCU to additional Tower
peripheral modules.
• MED-EKG: A sensor module that detects
EKG data (for use with Flexis MM parts only)
• USB Cable: For connectivity to a PC.
• DVD: Includes all you need to get up and
running in minutes. Comes complete with
