AM4376BZDND30

Overview

The AM4376BZDND30 is a microprocessor from the Texas Instruments Sitara family, featuring an ARM Cortex-A9 core. It operates at a maximum clock frequency of 300 MHz with a 32-bit data bus width. The device integrates 32 kB L1 instruction and data caches, plus 256 kB L2 cache. It utilizes a BGA-491 package and supports multiple I/O voltages including 1.2 V, 1.35 V, 1.5 V, 1.8 V, and 3.3 V. Operating temperatures range from -40°C to +105°C.

Feature Summary

• Integrates Programmable Real-Time Unit and Industrial Communication Subsystem (PRU-ICS) for deterministic real-time control tasks alongside the main application processor.
• Supports high-speed industrial communication interfaces including Ethernet MACs, CAN, SPI, and UART for robust connectivity in embedded systems.
• Features integrated memory management unit and hardware floating-point unit to accelerate complex computational workloads efficiently.

Applications

• Industrial automation controllers and programmable logic controllers
• Human-machine interface displays and operator panels
• Smart energy meters and utility infrastructure devices

Procurement Notes

Verify the specific suffix 'DND' confirms the 300 MHz speed grade and commercial/industrial temperature range. Confirm RoHS compliance status through official manufacturer documentation. Ensure ESD handling procedures are followed due to moisture sensitivity classification. Validate pinout compatibility during PCB layout finalization against the latest datasheet revision.

Selection Notes

Select this component when deterministic real-time performance via PRU-ICS is required alongside Linux-capable processing. Compare against higher-frequency variants like the AM4378 if greater application processing throughput is needed. Consider power consumption profiles relative to system thermal constraints within the specified operating temperature range.

Part Context

This part belongs to the AM437x Sitara processor series designed for cost-sensitive industrial applications. It shares the same BGA-491 footprint and peripheral set as other AM437x variants, differing primarily in clock speed and cache configurations. The series targets applications requiring reliable connectivity and real-time capabilities.

Replacement Considerations

The AM4376BZDNA80 offers a higher 800 MHz clock speed within the same package. The AM4378BZDND100 provides 1 GHz performance. Verify software compatibility and thermal design adequacy when migrating between these speed grades within the AM437x family.
