MAX® II CPLDs are optimized for control path applications such as power-up sequencing, which includes multi-voltage system power up and system reset, and chip-select generation. These two applications are often integrated into a single non-volatile, instant-on device.
Multi-voltage system power-up requires a device to be instantly on and ready to manage the power-up sequence for other devices on the PCB. As board density and the number of power planes on a board increases, the complexity of the power-up sequencing also increases. MAX II CPLDs can easily manage the power-up sequencing for all levels of system complexity.
Table 1 describes some MAX II CPLD features that serve these power-up sequencing needs.
