RK3588S GPIO Usage Instructions

RK3588S GPIO Usage Instructions

1. GPIO Circuit In the RK3588S, there are two types of GPIO that support 1.8V and configurable 1.8V/3.3V voltage levels. 2. GPIO Pin Name Description For example, functions such as GMAC1_PPSCLK, UART7_RX_M1, SPI1_CLK_M1 are multiplexed on GPIO3_C1, and only one function can be selected during allocation. Except for the boot-related GPIOs, the remaining IOs are … Read more

Signal Isolation in Low Power Design

Signal Isolation in Low Power Design

In low power designs with multiple power domains, there are many interactive signals between different power domains. If one power domain is powered off, the signals output from that power domain to another power domain that is still powered on need to be isolated. The reason is that the signals from the powered-off power domain … Read more
