對于電池供電的手持設備類應用8位MCU替代方案， 基于ARM Cortex-M3內(nèi)核的32位產(chǎn)品恐怕是最合適的選擇，性價比足夠高、功耗更低、靈活性大。但就連富士通的FM3系列都玩不轉要出售、TI幾乎也要放棄這塊市場轉向主攻Cortex-M0、M4，剩下的玩家又將如何實現(xiàn)差異化競爭，殺出一條生路呢？
張園根先生以Silicon Labs公司已獲成功的Precision32混合信號MCU全系列產(chǎn)品（包括適用于USB應用的SiM3Uxxx系列、適用于非USB應用的SiM3Cxxx系列、適用于超低功耗應用的SiM3Lxxx系列）為例，分析了Cortex-M3 MCU在工控儀表、智能家居、便攜醫(yī)療、物聯(lián)網(wǎng)無線終端、電腦外設等市場如何開辟差異化的8位替代之路。
32 位MCU是8位廠商向上開拓應用市場的必由之路，最重要的是如何做好集成。看起來似乎張三李四都會集成ARM內(nèi)核，但是最終的效果是有差別的。張園根指出：“Precision32 系列產(chǎn)品采用Silicon Labs的專利技術Crossbar架構，確保了最大的靈活性，加之SiM3Lxxx系列的令人贊嘆的超低功耗特性、使得Silicon Labs的Precision32 32位MCU系列在眾多ARM Cortex-M3 MCU中脫穎而出?！?
