7 Detailed Description

7.1 Overview

The AM263Px Sitara Arm® Microcontrollers are built to meet the complex real-time processing and control

needs of next generation industrial and automotive embedded projects. AM263Px uniquely combines advanced

computing with industry leading real-time control peripherals to meet the growing performance needs of

applications such as HEV/EV (traction inverters, on-board chargers, and DC-DC converters), motor drives,

renewable energy, energy storage, and other general real-time constrained systems. AM263Px combines up to

four Cortex-R5F MCUs, a real-time control subsystem (CONTROLSS), a Hardware Security Module (HSM), and

one instance of Sitara’s PRU-ICSS, making AM263Px designed for advanced motor control and digital power

control applications.

The multiple R5F cores are arranged in cluster with 256KB of shared tightly coupled memory (TCM) along

with 3MB of shared SRAM. The multiple Arm® cores can be optionally programmed to run in lock-step option

for different functional safety configurations. Extensive ECC is included on on-chip memory, peripherals, and

interconnect for enhanced reliability. Cryptographic acceleration and secure boot are also available on AM263Px

devices in addition to granular firewalls managed by the HSM for developers to design the most secure systems.

The Real-Time Control Subsystem (CONTROLSS) is a revolutionary subsystem integrated into the device.

CONTROLSS contains multiple digital and analog control peripherals including: ADC, CMPSS, EPWM, ECAP,

and EQEP, among others to enable efficient execution of critical sense/process/actuate real-time signal chain

control loops. The integrated crossbar (XBAR) infrastructure enables flexible configuration and routing of

external signals to internal ports and internal signals to external pins.

The PRU-ICSS in AM263Px provides the flexible industrial communications capability necessary to run

EtherCAT®, PROFINET®, Ethernet/IP™, or for standard Ethernet connectivity and custom I/O interfacing. The

PRU also enables additional interfaces in the SoC including sigma delta decimation filters and absolute encoder

interfaces. The CPSW interface also provides two standard Ethernet ports.

TI provides a complete set of microcontroller software and development tools for the AM263Px family of

microcontrollers in addition to multiple pin-to-pin compatible devices for scalability and ease of use.
