AM2434

The AM2434 is an extension of Sitara’s industrial-grade portfolio into high-performance microcontrollers. The AM2434 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 AM2434 provides scalable performance with up to four Cortex-R5F MCUs, one Cortex-M4F, and two instances of Sitara’s gigabit TSN-enabled PRU_ICSSG.

The AM2434 SoC architecture was designed to provide best-in-class real-time performance through the high-performance Cortex-R5F cores, tightly-coupled memory banks, configurable SRAM partitioning, and dedicated low-latency paths to and from peripherals for rapid data movement in and out of the SoC. This deterministic architecture allows for AM2434 to handle the tight control loops found in servo drives while the peripherals like FSI, GPMC, ECAPs, PWMs, and encoder interfaces help enable a number of different architectures found in these systems.

The SoC provides flexible industrial communications capability including full protocol stacks for EtherCAT target, PROFINET device, Ethernet-IP adapter, and IO-Link Controller. The PRU_ICSSG further provides capability for gigabit and TSN based protocols. In addition, the PRU_ICSSG enables additional interfaces including a UART interface, sigma-delta decimation filters, and absolute encoder interfaces.

Functional safety features can be enabled through the integrated Cortex-M4F along with dedicated peripherals which can all be isolated from the rest of the SoC. The AM2434 also supports secure boot.
