Multi-master I2C operation



Support 7bits and 10bits address mode



Software programmable clock frequency and transfer rate up to 400Kbit/s in the fast

mode



Serial 8bits oriented and bidirectional data transfers can be made at up to 100Kbit/s

in the standard mode



GPIO



Totally 160 GPIOs



All of GPIOs can be used to generate interrupt to Cortex-A17



GPIO0 can be used to wakeup system from low-power mode



The pull direction(pullup or pulldown) for all of GPIOs are software-programmable



All of GPIOs are always in input direction in default after power-on-reset



The drive strength for all of GPIOs is software-programmable



USB Host2.0



1.2.19 Others



Temperature Sensor(TS-ADC)



3 bipolar-based temperature-sensing cell embedded



3-channel 12-bits SAR ADC



SAR-ADC(Successive Approximation Register)



3-channel single-ended 10-bit SAR analog-to-digital converter



eFuse



Two high-density electrical Fuse is integrated: 256bits (32x8) / 1024bits (32x32)



Support standby mode

Notes :

① : DDR3/LPDDR2/LPDDR3 are not used simultaneously as well as async and sync ddr nand flash

②: In RK3288, Video decoder (except H.265) and encoder are not used simultaneously because of

shared internal buffer
