Designed for a wide range of applications employing 32-bit MCUs, the AT73C224 power manager with integrated real-time clock supplies the necessary voltages and currents to the main sections of generic 32-bit MCU-based applications including MCU core, memory, I/O, USB host, and interfaces. The device provides four power-output channels and its real-time clock pairs with a 1-µA crystal oscillator and backup battery management system. It also integrates several state machines, selectable during factory test, to significantly reduce stabilized output delivery time during the startup sequence or default voltage configuration. All the programmable features of the AT73C224 are controllable via the MCU using TWI, SPI, or GPIO modes. Available in a 32-pin, 5 mm x 5 mm QFN package, price is $1.08 each/100,000.
