The K2E devices require power supplies to be sequenced in a proper order. This design demonstrates power sequencing for the 66AK2Ex and AM5K2Ex families of KeyStone II ARM+DSP and ARM-only multicore processors by use of the UCD9090. The UCD9090 is a 10-rail PMBus/I2C addressable power-supply sequencer and monitor. The UCD9090 provides both sequence and timing of the power supply enables. This design shows a power sequencing implementation specific to the K2E EVM platform.
Merkmale
- Power supply sequencing reference implementation for the 66AK2Ex and AM5K2Ex SoCs.
- Uses UCD9090 for power supply sequencing and monitoring for nine voltage rails.
- Uses the Fusion Digital Power Designer Software to configure and program the UCD9090.
- Complete system reference with schematics, BOM, design files, and HW Design Guide, implemented on the K2E EVM platform for testing and evaluation.
