Freescale系列单片机在业界也被称为MOTOROLA单片机系列，该系列部分单片机解密手法较为复杂，解密难度较高，但是，深圳龙芯世纪解密研究所在针对Freescale系列单片机的专项研究中已经取得重要成果，目前可解的MOTOROLA单片机型号多达上千个，我们在此没有详细列出可解型号，仅以下面的MC908JK8CDWE单片机为例进行说明，有Freescale系列单片机解密需求者，请查询我们的详细可解型号库，或直接与我们联系。
The MC908JK8CDWE is a member of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCUs). All MCUs in the family use the enhanced M68HC08 central processor unit (CPU08) and are available with a variety of modules, memory sizes and types, and package types.
MC908JK8CDWE单片机 特性
xxHigh-Performance M68HC08 Architecture
Fully Upward-Compatible Object Code with M6805, M146805, and M68HC05 Families
Low-Power Design (Fully Static with Stop and Wait Modes)
Maximum internal bus frequency:
8-MHz at 5V operating voltage
4-MHz at 3V operating voltage
Oscillator options:
Crystal or resonator
RC oscillator
8,192 bytes of user FLASH memory with security feature
256 Bytes of On-Chip RAM
Two 16-bit, 2-channel inerface modules (TIM1 and TIM2) with selectable input capture, output compare, and PWM capability on TIM1 channels
10-channel, 8-bit analog-to-digital converter (ADC)
15 general-purpose input/output (I/O) ports:
1 keyboard interrupt with internal pull-up
4 LED drivers (sink)
2x25mA open-drain I/O with pull-up
Serial Communications Interface Module (SCI)
