TI AM2632CNDFHAZCZR Sitara™ Dual-Core Arm Cortex-R5F MCU With Real-Time Control And Security

Shenzhen Mingjiada Electronics Co., Ltd., a renowned distributor and recycler of electronic components, now supplies/recycles TI's AM2632CNDFHAZCZR Sitara™ Dual-Core Arm Cortex-R5F MCU.

The TI AM2632CNDFHAZCZR is a high-performance microcontroller (MCU) within the Sitara™ series. Centred around a dual-core Arm Cortex-R5F architecture, it deeply integrates real-time control with comprehensive security features. Tailored for industrial automation, motor control, and digital power applications where real-time performance and security are paramount. Its high reliability, high integration, and flexible configuration make it the core component of choice for next-generation industrial embedded products.

I. AM2632CNDFHAZCZR Core Architecture: Dual-Core Arm Cortex-R5F Enables Efficient Computing

The AM2632CNDFHAZCZR incorporates two independent Arm Cortex-R5F cores, each operating at up to 400MHz, forming a powerful dual-core processing cluster. This architecture can be flexibly configured for either dual-core or lockstep modes, balancing computational performance with functional safety requirements. The Cortex-R5F core is optimised for real-time control scenarios, offering low latency and high determinism. Combined with its integrated cache and memory modules, it significantly enhances instruction execution efficiency and data processing speed.

The core's accompanying memory subsystem further reinforces computational reliability: Each CPU core incorporates a 16KB instruction cache (supporting 64-bit ECC error correction) and a 16KB data cache (supporting 32-bit ECC error correction), alongside an integrated 64KB tightly coupled memory (TCM) unit, also featuring 32-bit ECC protection. This effectively prevents errors during data transmission and storage. Additionally, the chip integrates 2MB of on-chip RAM (OCSRAM), divided into four 512KB storage units. This supports ECC error protection and an internal DMA engine, enabling it to fulfil the storage requirements for medium to high-complexity real-time control tasks without relying on external memory. This simultaneously reduces system design costs and power consumption.

II. Core Advantages of the AM2632CNDFHAZCZR: Exceptional Real-Time Control Capabilities

As an MCU dedicated to real-time control, the AM2632CNDFHAZCZR integrates a comprehensive suite of analogue and digital peripherals to form a complete real-time control subsystem (CONTROLSS). This enables precise response to external signals and rapid execution of control algorithms, making it suitable for diverse high-precision control applications.

At the sensing and driving level, the device incorporates five 12-bit SAR analogue-to-digital converters (ADCs). each supporting 6 single-ended channels or 3 differential channels with sampling rates up to 4 MSPS. Highly configurable digital logic, XBAR conversion start triggering, user-defined sample-and-hold (S+H), and flexible post-processing blocks (PPB) enable precise acquisition of diverse analogue sensor signals. Additionally, it incorporates one 12-bit digital-to-analogue converter (DAC), twenty analogue comparators (ten CMPSSA with Class-A programmable DAC reference, ten CMPSSB with Class-B programmable DAC reference), and two 4-channel Σ-Δ filter modules (SDFM), further enhancing signal acquisition precision and stability.

At the control output level, the device integrates 32 pulse width modulation (EPWM) modules, supporting single/dual PWM channels, advanced PWM configurations, and extended HRPWM time resolution. This enables precise speed regulation and control of actuators such as motors and power supplies. Additionally, it incorporates 10 enhanced capture (ECAP) modules and 3 enhanced quadrature encoder pulse (EQEP) modules for precise acquisition of external pulse signals. This enables real-time monitoring and feedback of motor speed, position, and other parameters, forming a complete closed-loop control chain.

Furthermore, the device supports multiple operating systems including BareMetal (OS-free), FreeRTOS, ThreadX, and Zephyr RTOS. Combined with the EDMA data movement engine, inter-processor communication modules, and spinlock synchronisation modules, it enables efficient multitasking scheduling and multi-core collaboration. This significantly enhances the system's real-time responsiveness and computational efficiency, effortlessly handling complex real-time control tasks.
