Overview of AM6421BSDGHAALVR – SINGLE-CORE 64-BIT ARM CORTEX-A5
The AM6421BSDGHAALVR is a Sitara AM64x family microprocessor implemented as a single 64-bit ARM® Cortex®-A53 core running up to 1.0 GHz in a 441-FCBGA (17.2 × 17.2 mm) surface-mount package. It targets industrial applications requiring a combination of 64‑bit application processing, integrated real‑time subsystems, and extensive security features.
With integrated co-processors and industrial communication engines, the device is optimized for designs that need real-time fieldbus/ethernet handling, secure edge compute, and flexible memory interfaces (DDR4/LPDDR4), while meeting industrial temperature and packaging requirements.
Key Features
- Core Single 64‑bit ARM® Cortex®‑A53 application core operating up to 1 GHz for application-level processing.
- Real-time and MCU Subsystems Integrated co-processors including ARM® Cortex®‑M4F and ARM® Cortex®‑R5F to offload real-time control and deterministic tasks.
- Industrial Ethernet & PRU Industrial Communication Subsystems (PRU‑ICSS) and multiple Ethernet interfaces: 2× 10/100 Mbps and 2× 10/100/1000 Mbps, supporting protocol offload and time-sensitive networking use cases.
- Memory Support DDR subsystem supporting LPDDR4 and DDR4; on-chip memory architecture described in the AM64x series includes up to 2 MB on-chip RAM with SECDED ECC and a DDRSS with 16‑bit data bus and inline ECC supporting high-speed memory operation.
- Security & Boot Hardware and cryptographic features including 3DES, AES, ARM TrustZone, ECC, RSA, SHA‑1/2, MD5, PKA, DRBG, Random Number Generator and Secure Boot to enable authenticated boot and protected storage.
- High-Speed I/O USB 3.1 (1) support and additional interfaces such as CANbus for vehicle and industrial network connectivity.
- Package & Environmental 441‑FCBGA (17.2 × 17.2 mm) surface mount package; industrial grade with operating temperature range −40 °C to 105 °C and RoHS compliance.
- SoC Services Centralized device management and data movement subsystems described for the AM64x series to manage boot, security, clock/reset/power and secure DMA/data movement.
Typical Applications
- Industrial Communication Gateways Use the PRU‑ICSSG engines and multiple Ethernet ports to implement protocol translation, TSN-enabled gateways, and fieldbus bridging.
- Industrial Control & Motion Systems Combine Cortex‑R5F and Cortex‑M4F real-time subsystems with on-chip RAM and PRU peripherals for motor control, I/O handling, and deterministic control loops.
- Secure Edge Compute and Protocol Offload Leverage the 64‑bit Cortex‑A53 core with hardware security features and DDR memory support for local analytics, secure data handling, and protocol processing.
- Field Instrumentation and Embedded Controllers Industrial temperature rating, CANbus and versatile memory/I/O options make the device suitable for embedded controllers and rugged instrumentation.
Unique Advantages
