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 compute 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.
For multicore AM263Px devices, the R5F cores are arranged in clusters of two Cortex-R5F cores per cluster. Each Cortex-R5F core has 256KB of shared tightly coupled memory (TCM). AM263Px has 3MB of shared SRAM spread across 6 banks of 512kB each. The multiple Arm® cores are configured to be in lockstep mode after device reset. The cores can be optionally programmed by the bootloader to run in dual core mode instead. Extensive ECC is included with the on-chip memory, peripherals, and interconnect for enhanced reliability. The HSM on AM263Px provides cryptographic acceleration, secure boot, and manages granular firewalls, enabling developers to design the most secure systems. AM263Px also includes a Trigonometric Math Unit (TMU) on each R5F core for accelerating trigonometric functions.
The Real-Time Control Subsystem (CONTROLSS) is a revolutionary subsystem integrated into the device. CONTROLSS contains multiple digital and analog control peripherals including: ADC, Resolver-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 Flash Subsystem (FSS) provides access to external Flash devices via Octal Serial Peripheral Interface (OSPI). The OpTIflash module features Region Based Address Translation (RAT), Fast Local Copy (FLC), and Remote L2 cache (RL2) functions that greatly improve Flash performance on the device.
The PRU-ICSS in AM263Px provides the flexible industrial communications capability necessary to run advanced Ethernet protocols such as EtherCAT®, PROFINET®, and Ethernet/IP™, or the PRU-ICSS can be used for standard Ethernet connectivity and custom I/O interfacing. The PRU-ICSS supports two Ethernet Ports at 10/100 Mbit operation. The PRU-ICSS also enables additional interfaces in the SoC including sigma delta decimation filters and absolute encoder interfaces. In addition to the PRU-ICSS, the Common Platform Switch (CPSW) interface provides up to two Ethernet ports that can support up to 10/100/1000 Mbit operation and supports standard Ethernet connectivity.
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.
