7.1 Overview

The AM261x Sitara Arm® Microcontrollers are built to meet the complex real-time processing and control needs of next generation industrial and automotive embedded projects. AM261x uniquely combines advanced computing with industry leading real-time control peripherals to meet the growing performance needs of applications such as HEV/EV (on-board chargers, DC-DC converters, Battery Management Systems), Two axis Servo drive, Industrial Digital Power control(energy storage, String Inverters), and other general real-time constrained systems. AM261x combines up to two Cortex-R5F MCUs, a real-time control subsystem (CONTROLSS), a Hardware Security Module (HSM), and two instances of Sitara’s TSN-enabled PRU-ICSS, making AM261x designed for advanced motor control and digital power control applications.

The R5F cores are arranged in cluster with 256KB of shared tightly coupled memory (TCM) along with 1.5MB of shared SRAM. The 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 AM261x 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 AM261x provides the flexible industrial communications capability necessary to run TSN, 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 AM261x family of microcontrollers in addition to multiple pin-to-pin compatible devices for scalability and ease of use.
