FAQ

What is the maximum operating frequency of the AM4372BZDN60 processor core?

The AM4372BZDN60 features an ARM Cortex-A9 processor core rated for 600 MHz operation. This fixed-frequency grade ensures predictable timing behavior in real-time industrial applications such as motion control and EtherCAT slave implementations, where deterministic interrupt latency and consistent instruction throughput are critical. The AM4372BZDN60 does not support dynamic voltage and frequency scaling (DVFS) beyond its specified 600 MHz point.

Does the AM4372BZDN60 support secure boot functionality?

No, the AM4372BZDN60 does not support secure boot. Secure boot capability is exclusive to AM437x High-Security (HS) variants, which feature factory-programmable fuses and cryptographic key storage. The AM4372BZDN60 belongs to the standard-security product line and lacks the hardware security module (HSM), secure watchdog timer, and fuse-based key provisioning required for authenticated boot. For secure boot requirements, consider AM4372BZDNA or other HS-suffix parts.

How many independent Ethernet MACs does the AM4372BZDN60 integrate?

The AM4372BZDN60 integrates two independent 10/100/1000 Mbps Ethernet MACs with an integrated 2-port switch fabric. Each MAC supports MII, RMII, and RGMII physical layer interfaces and includes full IEEE 1588v2 Precision Time Protocol hardware timestamping. This enables time-synchronized communication across distributed industrial nodes without requiring external switch ICs - a key requirement for AM4372BZDN60 deployments in motion control networks.

Can the AM4372BZDN60 directly interface with a resistive touch screen?

Yes, the AM4372BZDN60 can directly interface with a 4-wire, 5-wire, or 8-wire resistive touch screen using its integrated touch-screen controller (TSC) function within ADC0. The TSC supports pressure measurement, coordinate acquisition, and gesture detection without external components. This capability is enabled by configuring ADC0's analog multiplexer and sequencer - a design feature confirmed in the AM4372BZDN60's TRM and validated in TI's AM437x Industrial SDK touch examples.

What package type and ball count does the AM4372BZDN60 use?

The AM4372BZDN60 uses a 491-ball NFBGA package with ZDN suffix, measuring 17.0 mm × 17.0 mm with 0.65 mm ball pitch. This package employs via-channel array technology to simplify PCB routing, allowing escape routing on four-layer boards without microvias. The pinout matches other AM437x ZDN variants (e.g., AM4376BZDN80), enabling hardware reuse across performance grades in the AM437x family.
