It is specifically engineered for applications such as servo drives, PLCs and industrial robots that demand stringent requirements for real-time performance, communication capabilities and functional safety.

I. AM2432BKEGHIALXR Core Architecture and Processor Performance

The AM2432BKEGHIALXR employs a heterogeneous multi-core architecture to achieve an efficient division of labour between “real-time control + auxiliary management + communication processing”:

Main Core: Dual-core Arm Cortex-R5F (800MHz)

A 32-bit high-performance real-time kernel supporting ** both dual-core lockstep (DCLS) and dual-core parallel (AMP) ** operating modes, balancing functional safety with computational scalability.

Each core is equipped with 32KB I-Cache + 32KB D-Cache; the entire cache features SECED ECC error correction, providing resistance to interference and protection against data errors.

Tightly Coupled Memory (TCM): 64KB TCM per core in dual-core mode, totalling 128KB, with zero-wait access, supporting microsecond-level control loops.

Auxiliary Core: Single-core Arm Cortex-M4F (400MHz)

An independent coprocessor equipped with 256KB ECC SRAM, responsible for peripheral management, low-power tasks and protocol pre-processing, freeing up the R5F’s computing power to focus on real-time control.

On-chip Shared Memory

2MB OCSRAM (on-chip RAM), supporting flexible allocation of 8×256KB partitions, with full ECC support, meeting the data exchange and caching requirements of multi-tasking.

External Memory Interface

Supports 16-bit DDR4/LPDDR4 (up to 1600MT/s), with integrated ECC, enabling expansion to large-capacity memory to accommodate complex algorithms and data caching.

II. AM2432BKEGHIALXR Industrial Communication: TSN + Multi-Protocol, Real-Time Interconnection Core

The chip integrates a dual-port Gigabit PRU_ICSSG industrial communication subsystem, which is key to ‘real-time networking’ in industrial environments:
