每个SBC芯片的的电源输出都有些不同,选择时该注意哪些参数呢?
比如MCU用HC908GZ32,做CAN-LIN Gateway 该选MC33389呢还是MC33689呢? Freescale的Power Management Quick Reference 中推荐使用MC33689,但是在MC33689 Product Summary Page中又说“The 33689 is a SPI controlled SBC combining many functions with a LIN transceiver for slave node applications”
郁闷阿,高手解释一下该怎么选?
