AM243x Sitara™ Microcontrollers (AM2431, AM2432, AM2434)
Brand: Texas Instruments · SKU: AM243A · MPN: AM243A (Likely a base part number for the AM243x series) · Category: Components
The AM243x is an extension of the Sitara’s industrial-grade portfolio into high-performance microcontrollers, built for industrial applications like motor drives and remote I/O modules, requiring real-time communications and processing. The family offers scalable performance with up to four Arm Cortex-R5F MCUs, one Arm Cortex-M4F MCU, and two instances of Sitara's gigabit TSN-enabled PRU_ICSSG. The architecture is designed for best-in-class real-time performance using high-performance Arm Cortex-R5F cores, Tightly-Coupled Memory (TCM) banks, configurable SRAM partitioning, and dedicated low-latency paths to and from peripherals for rapid data movement. Specific core configurations include up to 2x Dual-core Arm Cortex-R5F subsystems at up to 800MHz (with 32KB I-cache and 32KB D-cache per R5F core) and 1x Single-core Arm Cortex-M4F MCU at up to 400MHz with 256KB SRAM with SECDED ECC. High-speed interfaces include an integrated Ethernet switch (CPSW) supporting up to 2 external Ethernet
