The figure below is the high level block diagram of BeagleBone® AI. For detailed layout information please check the schematics.
AM572x Sitara™ Processor#
The Texas Instruments AM572x Sitara™ processor family of SOC devices brings high processing performance through the maximum flexibility of a fully integrated mixed processor solution. The devices also combine programmable video processing with a highly integrated peripheral set ideal for AI applications. The AM5729 used on BeagleBone® AI is the super-set device of the family.
Programmability is provided by dual-core ARM® Cortex®-A15 RISC CPUs with Arm® Neon™ extension, and two TI C66x VLIW floating-point DSP core, and Vision AccelerationPac (with 4x EVEs). The Arm allows developers to keep control functions separate from other algorithms programmed on the DSPs and coprocessors, thus reducing the complexity of the system software.

TPS6590379 PMIC#
The Texas Instruments TPS6590379ZWSR device is an integrated power-management IC (PMIC) specifically designed to work well ARM Cortex A15 Processors, such as the AM5729 used on BeagleBone® AI. The datasheet is located here https://www.ti.com/lit/ds/symlink/tps659037.pdf
The device provides seven configurable step-down converters with up to 6 A of output current for memory, processor core, input-output (I/O), or preregulation of LDOs. One of these configurable step-down converters can be combined with another 3-A regulator to allow up to 9 A of output current. All of the step-down converters can synchronize to an external clock source between 1.7 MHz and 2.7 MHz, or an internal fallback clock at 2.2 MHz.
The TPS659037 device contains seven LDO regulators for external use. These LDO regulators can be supplied from either a system supply or a preregulated supply. The power-up and power-down controller is configurable and supports any power-up and power-down sequences (OTP based). The TPS659037 device includes a 32-kHz RC oscillator to sequence all resources during power up and power down. In cases where a fast start up is needed, a 16-MHz crystal oscillator is also included to quickly generate a stable 32-kHz for the system. All LDOs and SMPS converters can be controlled by the SPI or I2C interface, or by power request signals. In addition, voltage scaling registers allow transitioning the SMPS to different voltages by SPI, I2C, or roof and floor control.
One dedicated pin in each package can be configured as part of the power-up sequence to control external resources. General-purpose input-output (GPIO) functionality is available and two GPIOs can be configured as part of the power-up sequence to control external resources. Power request signals enable power mode control for power optimization. The device includes a general-purpose sigma-delta analog-to-digital converter (GPADC) with three external input channels.
