The TWR-MCF51JE-KIT is a ColdFire Flexis MCF51JE low power USB Tower System Module. The MCF51JE256/128 (JE256/128) provides ultra low power operation, USB connectivity and high measurement accuracy, all in a single 32bit microcontroller (MCU), allowing designers to develop a more fully featured system at a lower cost. The JE256/128 integrates high resolution analog to digital converter (ADC) and digital to analog converter (DAC) modules, rich peripheral set including a USB 2.0 host/device/on the go controller, multiple serial interfaces and an external bus interface. The development board as a standalone debug tool and can also be combined and used as part of the modular tower system development platform.
