AM6421BSEFHAALVR

Microprocessors Overview

The AM6421BSEFHAALVR is a single-core 64-bit Arm Cortex-A53 microprocessor within the AM64x Sitara family, operating at up to 1 GHz. It integrates two dual-core Arm Cortex-R5F subsystems (up to 800 MHz) and one single-core Arm Cortex-M4F MCU (up to 400 MHz). The device features 2 MB of on-chip RAM with ECC, supports LPDDR4/DDR4 memory via a 16-bit bus, and includes two PRU-ICSSG industrial communication subsystems. It utilizes a 441-pin FCBGA package.

Microprocessors Procurement Notes

Verify the specific feature code suffix against the official datasheet nomenclature table to confirm enabled peripherals such as functional safety or CAN-FD support. Ensure the ordering suffix matches the required package type and temperature range. Cross-reference the device ID register values to validate silicon revision compatibility with existing software builds.

Microprocessors Selection Notes

Select this component when a single high-performance application core is sufficient alongside robust real-time control requirements. The integrated PRU-ICSSG modules provide necessary industrial connectivity without external controllers. Consider the available on-chip memory partitioning for isolating Linux workloads from safety-critical real-time tasks.

Microprocessors Part Context

This processor belongs to the AM64x Sitara series, an extension of Texas Instruments' industrial-grade heterogeneous processors.
