Overview
The MCF51JE256/128 (JE256/128) provides
ultra-low-power operation, USB connectivity
and high measurement accuracy, all in
a single 32-bit microcontroller, allowing
designers to develop a more fully featured
system at a lower cost. The JE256/128
integrates high-resolution ADC and DAC
modules and a rich peripheral set including a
USB 2.0 host/device/OTG controller, multiple
serial interfaces and an external bus interface.
The JE256/128 is part of the Freescale
Flexis microcontroller series, which includes
both 8-bit S08 and 32-bit V1 ColdFire
microcontrollers that have a common set
of peripherals and development tools to
deliver the ultimate in migration flexibility.
The JE256/128 family is also easy to use.
Freescale provides a comprehensive suite
of development tools and software to help
developers design quickly and easily.

Modular Tower Development System
TWR-MCF51JE-KIT ($119 USD*)
TWR-MCF51JE ($69 USD*)
The Freescale Tower development
system provides the user with a modular,
reconfigurable demonstration and
development platform.
The TWR-MCF51JE-KIT soldered with
100LQFP MCF51JE256 consists of:
• TWR-MCF51JE stand-alone development
board
• TWR-SER serial boards that support USB
and RS232
• TWR-ELEV elevator board that connects the
MCU and serial boards
• USB cable
Flexis JE Series
The TWR-MCF51JE can also be ordered
independently. A getting-started DVD included
with the board includes necessary software,
documents and resources to jumpstart new
product development.
