Part Number:TWR-MCF51JE-KIT

The TWR-MCF51JE-KIT module is a development kit for the MCF51JE ColdFire V1 Low-Power USB 32-bit MCUs. It is designed to enable the development of long-lasting portable applications with USB connectivity. The TWR-MCF51JE operates as a standalone debug tool and can also be combined and used as part of the modular Tower System development platform (TWR-MCF51JE-KIT) which includes Tower System Serial Module (TWR-SER) and Tower System Elevator Modules (TWR-ELEV)

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 NXP 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. NXP provides a comprehensive suite of development tools and software to help developers design quickly and easily.

Key Applications: HVAC building control systems, PC peripherals, Lighting control systems, Industrial networking products, Portable medical devices
