Other Parts Discussed in Thread: OMAP-L138

现在为了简化电路,OMAP-L138 在使用的过程中,我们只使用UART0 UART1 UART2 SPI0 SPI1 I2C0 ,芯片的工作频率456Mhz,其他的功能都不用

(1)CVDD(Coresupply) (2)RVDD(Internal RAMsupply) (3)DVDD18(I/O supply)(4)DVDD3318_A(I/O supply)(5)DVDD3318_B(I/O supply) (6)DVDD3318_C(I/O supply) (7)VSS(Ground) 这些管脚是不是必须接?

(1)USB0_VDDA33 (2)USB0_VDDA18 (3)USB0_VDDA12(4)USB_CVDD(5)USB1_VDDA33(6)USB1_VDDA18(7)SATA_VDD

(8)SATA_VSS (9)DDR_DVDD18 这些管脚是不是可以不接? 若是需要接,哪些是必须要接的?
