| [问：libin11] | 请问这种单片机的主要应用场合是什么？相比ARM芯片有何优势？ | |
| [答：Vincent] | UF32 supports USB mass storage class application, it has built-in flash card reader controllers. UF32 is in Freescale S12 core architecture, to compare with ARM, they are 2 very different architecture, S12 is in CISC but ARM is in RISC architecture. Deciding on MCU performance should not be purely compare the core architecture, peripheral support, compiler/development tool support and manufacturing support are also the key factors to determine. UF32 has built-in major flash card controller modules, complete support for software compiler for C/C++/assembly and development tools. There is no equivalent ARM product is available for similar application. | [2004-12-2 11:33:36] |
| [问：buswalker] | Freescale 是否提供UF32的USB2.0固件程序？ | |

| [问：libin11] | 功耗如何？是否可以用于便携式产品？ | |
| [答：Derek] | 1. If USB and other memory interfaces are not used, and the PLL is not enabled, the UF32 runs at 6MHz with 12MHz crystal. The current under this mode is around 10mA (actual current depends on applications), the STOP mode is around 100uA at room temperature. It is suitable for some portable devices. | [2004-12-2 11:35:09] |
| [问：电池] | 是host端还是设备端，价格在什么范围 | |

| [问：asun] | 作为16位USB单片机，与集成有ARM核或者其它软核的FPGA的USB开发有什么优缺点。更适合于那些方面的应用。譬如，我如果要完成一个高速信号采集，通过USB通道上传数据，单片机能不能达到那么高的速度。 | |
| [答：Chen] | UF32仍是传统意义上的16位单片机，但它内部集成了高速USB接口及控制电路，还有收发器及收发缓存区，另外还有专用的集成队列模块，所有这些特性能大大提高其数据处理及传输得速度，同时也大大减轻了软件的负担。至于对于某个具体的应用UF32是否能达到其要求，应该对数据处理和传输的要求进行具体分析。 | [2004-12-2 11:38:37] |
| [问：ptwang] | s12主要用于哪一方面啊？与硬盘或是记忆卡的通信还是控制他们？还是用于计算机主板，作为cpu与硬盘的通信中间部分？ | |
| [答：Derek] | The S12 core mainly handles the USB Mass Storage Flow, does the physcial/logical table translations for Memory Stick and SmartMedia . ATA and other memory cards interfaces have got their own modules to control. The transfer of data between PC and storage devices are through the IQUE Module. | [2004-12-2 11:39:05] |
| [问：taopin] | 请问该芯片容易购买吗？ 有参考设计图吗？ | |

| [问：lee2008] | mc9s12uf32与dsp比较有什么优缺点？谢谢 | |
| [答：Vincent] | UF32 is in S12 core architecture. S12 is 16bit general purpose processor, it is good for general purpose control while DSP is specialised in mathematic calculation. For UF32 defined applications, firmware will need to perform mostly data movement and bit manipulation type of tasks, S12 architecture has benefit over DSP equivalent product. | [2004-12-2 11:40:05] |
| [问：huali] | 能否对采用ATA/ATAPI转接桥实现保密功能的设计，简单的介绍一二，谢谢！ | |
| [答：Derek] | 1. If proprietary encryption is used. It can be done in UF32. If you want to use the Microsoft DRM encryption, it can"t be done by UF32 alone. It must work with other CPU with more memory sizes. | [2004-12-2 11:41:33] |
| [问：ffcsdx] | 我用的是GP32芯片，请问如何将其SCI转换为USB接口（硬件连接）？MC9S12UF32芯片在线编程如何实现，其USB2.0接口寄存器编程实现方法及在汽车电子上具体实例？ | |
| [答：Chen] | GP32没有内置的USB接口电路，应该通过串行通讯接口与其它的USB接口电路进行通讯。UF32可以通过BDM（背景调试模块）接口进行在线编程，也可以通过串行通讯接口进行在线编程。 | [2004-12-2 11:42:35] |
| [问：askl] | UF32支不支持IDE模式的CF卡读写？ | |
| [答：Chen] | 可以支持，但要通过ATA接口控制方式。 | [2004-12-2 11:43:32] |
| [问：luomingq] | 在系统解决方案中，usb模块硬件架构和软件架构是如何协同设计和验证的？针对外存读写速度慢和host端请求快的矛盾是如何解决的？ | |
| [答：Derek] | 1. For USB, we use the USBCV for testing. For USB working under Mass Storage Class, we tested differents mass storage devices under different PC systems. Regarding the slow speed mass sotrage devices, USB handles this by NAK the host if device is not available to send or receive data. | [2004-12-2 11:44:29] |
| [问：小康] | 您好！我想问一下此类单片机的最大容量和最高传输速度 | |
| [答：Law Wai] | UF32 MCU has 32K flash and 3.5K SRAM. The USB interface module, the ATA interface module and the CF/MS/SD/SM card interface module run at 60MHz. The transfer rate of different interfaces depends on the corresponding protocol. For example, USB HS is 480Mbps and UDMA4 is 60MB/s. | [2004-12-2 11:45:42] |
| [问：luomingq] | 实际读写外存的速度是多少？ | |
| [答：Derek] | For ATA hardisk supports UDMA mode 4. The speed under PC system with 2.6GHz Pentium 4 is around 33MByte/s buffer read and 22MByte/s buffer write. The speed depends on the PC systems and the hardisk performance. | [2004-12-2 11:46:21] |
| [问：youyubing] | uf32程序编译器和飞思卡的例程序在用于商业的时候是否要许可和付费？ | |
| [答：Chen] | 飞思卡尔的所有参考设计以及范例程序的源程序都是免费的。UF32的汇编编译是完全免费的，但它的C程序编译有一定的限制，超过一定程序容量之后需要付费。具体情况请与我们的销售人员或代理商联系。 | [2004-12-2 11:50:58] |
| [问：jim90us] | ATA 的传输模式是如何设置的?可通过单片机软件设置吗?ATA 设备识别是如何完成的?谢谢 | |
