3 Description
AM243x is an extension of Sitara’s industrial-grade portfolio into high-performance microcontrollers. The AM243x device is built for industrial applications, such as motor drives and remote I/O modules, which require a combination of real-time communications and processing. The AM243x family provides scalable performance with up to four Cortex-R5F MCUs and one Cortex-M4F.
AD
The AM243x SoC architecture was designed to provide best-in-class real-time performance through the high- performance Arm Cortex-R5F cores, Tightly-Coupled Memory banks, configurable SRAM partitioning, and
V
dedicated low-latency paths to and from peripherals for rapid data movement in and out of the SoC. This
A
deterministic architecture allows for AM243x to handle the tight control loops found in servo drives while the
NCE INFO
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
R
peripherals which can all be isolated from the rest of the SoC. AM243x also supports secure boot.
