Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM-based industrial processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM4379BZDND30 | 1000-MHz Cortex-A9 core, same PRU-ICSS, identical peripheral set, but rated for –40°C to +90°C (not +105°C) | Better raw compute performance for intensive GUI or DSP workloads; less suitable for high-ambient-temperature industrial enclosures | Select AM4379BZDND30 when CPU-bound tasks dominate and ambient temperature stays ≤90°C; retain AM4376BZDND30 for extended thermal environments. |
| AM4377BZDND30 | 300-MHz Cortex-A9 core, same package and peripherals, but lacks SGX530 graphics and PRU-ICSS industrial protocol support | Targeted at cost-sensitive, non-graphical, non-real-time industrial gateways or data concentrators | Choose AM4377BZDND30 only for simple Linux gateway functions without graphics or EtherCAT; AM4376BZDND30 remains required for real-time or HMI use cases. |

FAQ
What is the maximum operating frequency of the AM4376BZDND30?
The AM4376BZDND30 operates at a maximum frequency of 800 MHz on its ARM Cortex-A9 core. This speed is validated across the full industrial temperature range (–40°C to +105°C) and supports Linux-based real-time applications with predictable interrupt latency. The AM4376BZDND30 does not support dynamic overclocking beyond this rated frequency.
Does the AM4376BZDND30 include hardware security features?
Yes, the AM4376BZDND30 includes hardware crypto accelerators for AES-128/256, SHA-1/256, DES/3DES, and RNG operations. However, secure boot, debug security, and trusted execution environment features are exclusive to AM437xHS (High-Security) variants and are not implemented in the standard AM4376BZDND30.
What package type and pin count does the AM4376BZDND30 use?
The AM4376BZDND30 uses a 491-pin NFBGA package (ZDN suffix) with 17.0 mm × 17.0 mm body size and 0.65-mm ball pitch. It employs Via Channel Array technology to simplify PCB routing and improve thermal dissipation, and is mechanically and electrically compatible with other AM437x ZDN variants.
Can the AM4376BZDND30 support dual-display output?
No, the AM4376BZDND30 contains a single Display Subsystem (DSS) supporting one primary display interface (RGB, YUV, or LVDS) with resolutions up to 2048×2048. While it offers overlay and windowing for multiple video/graphic layers, it does not provide dual independent display controllers or simultaneous dual-panel drive capability.
What industrial communication protocols are supported by the PRU-ICSS in the AM4376BZDND30?
The PRU-ICSS in the AM4376BZDND30 supports EtherCAT®, PROFIBUS®, PROFINET®, EtherNet/IP™, EnDat 2.2, and Sercos III through TI's industrial software development kit (SDK). These protocols run independently on the PRU cores, enabling deterministic real-time I/O without loading the ARM Cortex-A9 CPU.
