| [问：dongjy] | 您好，我来自北京大学深圳研究生院。我的问题是：一般来说，降低功耗和提高性能是互为矛盾的，降低功耗必将有损性能，而性能的提高又是以牺牲功耗为代价。飞思卡尔TM的新型低端RS08内核能够比相关产品更小化，那么这对矛盾将更加突出，请教飞思卡尔是如何处理的？这款新产品在性能和功耗方面较之同类产品有何优秀表现？谢谢！ | |
| [答：飞思卡尔] | 是的，一般来说，降低功耗和提高性能是互相矛盾的。但在RS08中，这个矛盾已经得到了很好的解决。例如，一般的MCU在低电压工作时，总线频率也要降低；而RS08由于内置了稳压器，所以在整个电压范围（1.8～5.5V）都可以跑到最大10MHz的总线频率。总的来说，这是因为RS08与S08一样，都采用了最新的半导体工艺，使得其工作电压和功耗都大大降低了。 | [2006-6-16 10:56:27] |
| [主持人：ChinaECNet] | 各位观众，现在用户提问很踊跃，专家正在逐一回答。请耐心等待您问题的答案，同一问题请不要多次提交。 | [2006-6-16 10:57:11] |

| [问：yujiujiu] | 您好，我想了解一下，紧凑型代码的含义 | |
| [答：飞思卡尔] | 例如，RS08增加了一些小型和短型寻找方式的指令。这些指令只有一个字节，而这一个字节中即有操作数，也有地址。所以，这样的代码是非常紧凑的。 | [2006-6-16 11:54:32] |
| [问：kitoff] | can I use my CW for RS08 development? | |
| [答：飞思卡尔] | What version is it? If its CodeWarrior 5.0 or lower, you need to update it for RS08. | [2006-6-16 11:55:17] |
| [问：yyp709] | 闪存ID码有几位?它的保密性能如何? | |
| [答：飞思卡尔] | Flash ID is used for MCU identification, it is 12-bit, it do nothing with security. There is a security bit (SECD) in NVOPT register, when programmed flash access through BDM will be blocked. | [2006-6-16 11:55:37] |
| [问：yyp709] | 如何实现数据或程序的安全加密?采用那种算法?多少位? | |

| [问：feng75329] | RS08支持工业级吗？ | |
| [答：飞思卡尔] | 目前的好像只有C级的，即-40C～85C。 | [2006-6-16 11:57:55] |
| [问：chamonix] | 补充，我说的资源主要是寄存器资源（查散转表时用），Flash用程序空间不够应该容易扩展，是这样吧？ | |
| [答：飞思卡尔] | Flash space is 2K for programming. If the firmware is larger than 2K, need to use other MCU with bigger Flash. Not to confuse the paging window, it is not used to store program, it is used for data access to upper page memory through direct page instructions. | [2006-6-16 11:59:07] |
| [问：羚羊] | RS08 MCU可在环境温度100度下正常工作吗 | |
| [答：飞思卡尔] | The first device MC9RS08KA2 is qualified up to 85C. Freescale may qaulify for higher temperature for further RS08 device if it is needed by the market. | [2006-6-16 12:00:27] |
| [问：烈火旋灯] | RS08在做产品的时候如何烧写程序？用什么工具，价格如何？ | |

| [问：] | 有适合汽车级温度的产品? | |
| [答：] | No. | |
| [问：] | 主要用于哪方面的开发？ | |
| [答：] | Small applicances, space sensitive and cost sensitive applications. | |
| [问：] | 能说说RS08的市场推广计划吗？ | |
| [答：] | MC9RS08KA1/2 is Freescale's first product on RS08 core, we are going to have other new products on this low-cost platform in future | |
| [问：] | Switching bands and pages is very troublesome. Does Freescale have any solution or software for reference? | |
| [答：] | Not to confuse the paging window with program segmentation. Paging is not used to store program, it is used for data access to upper page memory through direct page instructions. You could write a linear 2K program and stored in Flash (as in S08/HC08). Only time you need to switch the page (by simply write to the page register) if your accessing location is not in the first page. | |
| [问：] | 普及该芯片，价格是门槛吗？ | |
| [答：] | Not on MC9RS08KA1/KA2 as our target resale is under US$0.5 | |
| [问：] | 因为它的体积小而功能不减，若价格问题无法解决的话，在小电子产品中的应用可能会受限，请问若大量购买它的价格的最低极限？ | |
