Description
General part information
UCD90320U Series
The UCD90320U device is a 32-rail PMBus™ addressable power sequencer and system manager in a compact 0.8-mm pitch BGA package. ULA mold compound is adopted to reduce the soft errors caused by alpha particles. The device scans the user configuration SRAM to detect single event upset (SEU). Both features provide higher reliability for the applications.
The 24 integrated ADC channels (AMONx) monitor the power supply voltage, current, and temperature. Of the 84 GPIO pins, 8 can be used as digital monitors (DMONx), 32 to enable the power supply (ENx), 24 for margining (MARx), 16 for logical GPO, and 32 GPIs for cascading, and system function.
The 32 ENx pins and the 16 LGPOx pins can be configured to be active driven or open drain outputs.
