AM243x is an extension of the Sitara’s industrial-grade family of heterogeneous Arm processors. AM243x is built for industrial applications, such as motor drives and programmable logic controllers (PLCs), which require a unique combination of real-time processing and communications with applications processing. AM243x combines two instances of Sitara’s gigabit TSN-enabled PRU-ICSSG, up to four Cortex-R5F MCUs and a Cortex-M4F MCU.
AM243x is architected to provide real-time performance through the high-performance R5Fs, Tightly-Coupled Memory banks, configurable SRAM partitioning, and low-latency paths to and from peripherals for rapid data movement in and out of the SoC. This deterministic architecture allows for AM243x to handle the tight control loops found in servo drives, while the peripherals like FSI, GPMC, PWMs, sigma delta decimation filters, and absolute encoder interfaces help enable a number of different architectures found in these systems.
The PRU-ICSSG in AM243x provides the flexible industrial communications capability necessary to run gigabit TSN, EtherCAT, PROFINET, EtherNet/IP, and various other protocols. In addition, the PRU-ICSSG also enables additional interfaces in the SoC including sigma delta decimation filters and absolute encoder interfaces.
Functional safety features can be enabled through the integrated Cortex-M4F along with its dedicated peripherals which can all be isolated from the rest of the SoC. AM243x also supports secure boot.
