产品参数

描述

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, 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 ColdFire V1 microcontrollers with a common set of peripherals and development tools to deliver the ultimate in migration flexibility. The JE246/128 family is also easy to use. Freescale provides a comprehensive suite of development
tools and software to help developers design quickly and easily.
