AT73C211-ZI Application Field and Working Principle

AT73C211-ZI is a low voltage power management integrated circuit (PMIC) from Atmel Corporation. It is a highly specialized PMIC and is known for its performance reliability and low power consumption. The chip features two independent power-domain management systems, one for the system core and one for the peripherals, and includes a programmable logic interface for system configuration and control. The AT73C211-ZI has a wide range of uses and applications. It is suitable for a multitude of designs, ranging from applications that require low power consumption to more demanding applications where reliability, low power consumption and fast Boot up times are needed. The AT73C211-ZI PMIC offers many advantages to the user, such as:

• Low power consumption
• Low voltage operating range
• High reliability
• Wide temperature range
• Fast boot up time
• Programmable logic interface

The AT73C211-ZI is based on a modified version of the widely used ARM 7 family of microprocessors. This modified version includes features intended specifically for PMICs, such as a wide variety of features for low power consumption and an extended temperature range. Additionally, the AT73C211-ZI microprocessor is designed to operate in a wide variety of voltage ranges, making it suitable for a wide range of applications and systems. The AT73C211-ZI PMIC consists of five operational domains: the core domain, the peripheral domain, the memory domain, the I/O domain and the dedicated logic domain. The core domain consists of two components, the core logic unit (CLU) and the PLL controller. The CLU handles the essential functions of the PMIC, such as the system clock and power supply and the real-time clock. The PLL controller is responsible for clock generation and calibration of the circuit. The peripheral domain consists of several components, including the system memory controller, the interrupt controllers, and the programmable logic units (PLUs). The system memory controller is responsible for managing access to the system\'s system memory and ensuring efficient access of data and instructions. The interrupt controllers are responsible for managing the flow of interrupts from different components of the PMIC to the system processor. The PLUs are responsible for additional logic operations, such as generating PWM signals and decoding I2C commands. The memory domain consists of components such as the system QSPI interface, the peripheral QSPI interface, the SRAM interface, and the eMMC controller. The system QSPI interface is responsible for providing interface between the system processor and the peripherals and memory devices. The peripheral QSPI interface allows devices, such as Ethernet PHYs and serial EEPROMs, to be connected to the system. The SRAM interface acts as a buffer between the system processor and the system memory. The eMMC controller is responsible for managing the operation of the system NAND Flash memory. The I/O domain consists of the system I/Os, which are connected to the system processor, the system I2C, SPI and UART for device communication, and the system GPIOs for general purpose input and output. Additionally, the I/O domain includes the system timer and the GPIO controller. The timer is responsible for generating system timing signals. The GPIO controller is responsible for managing the general purpose input and output. The dedicated logic domain consists of components such as the direct digital synthesis (DDS) modulator, the PLL controller, voltage regulators, the shutdown controller, and the reset controller. The DDS modulator is responsible for supplying digital information to the system processors. The PLL controller is responsible for providing the system processor with a highly stable clock source. The voltage regulators are responsible for independently controlling the voltage levels of different components. The shutdown controller is responsible for shutting down the system to conserve power. The reset controller is responsible for resetting the system when necessary.In summary, the AT73C211-ZI PMIC is a specialized power management integrated circuit that offers low power consumption and reliability, with a wide temperature range and the ability to operate in a wide variety of voltage ranges. It offers flexible programming for system configuration and control, with system I/O, memory and logic domains for effective management of peripherals and system resources.
