AM4376BZDND80

Overview

The AM4376BZDNA80 is a microprocessor from the Texas Instruments Sitara family, featuring an ARM Cortex-A9 core with a maximum clock frequency of 800 MHz. 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. The processor includes 32 kB L1 instruction and data caches, 64 kB data RAM, 256 kB data ROM, and a 256 kB L2 cache. Operating temperatures range from -40°C to +105°C.

Feature Summary

• Integrates Programmable Real-Time Unit and Industrial Communications Subsystem (PRU-ICS) for deterministic real-time control tasks alongside the main application processor.
• Supports diverse industrial communication protocols through integrated interfaces such as Ethernet, CAN, I2C, SPI, UART, and USB.
• Features floating-point arithmetic capabilities within the ARM Cortex-A9 core to accelerate complex mathematical computations.

Applications

• Industrial automation controllers requiring deterministic real-time processing
• Human-machine interface (HMI) displays in factory environments
• Smart energy management systems and smart grid infrastructure

Procurement Notes

Verify the specific suffix against official documentation to confirm pin compatibility and feature set. Ensure the component meets RoHS compliance requirements for your target market. Confirm that the BGA-491 package handling procedures align with your manufacturing capabilities. Validate operating temperature ranges against your system's thermal design specifications before finalizing procurement.

Selection Notes

Select this component when deterministic real-time performance is required alongside general-purpose computing. The inclusion of PRU-ICS allows offloading time-critical tasks from the main OS. Consider the extensive peripheral set for direct connectivity to industrial sensors and actuators without additional bridge chips. Evaluate power consumption profiles against available cooling solutions for enclosed enclosures.

Part Context

This part belongs to the AM437x Sitara series, designed for cost-sensitive embedded applications. It shares architectural similarities with higher-performance variants but offers optimized resource allocation for standard industrial control tasks. The series emphasizes low power consumption while maintaining robust connectivity options for IoT and industrial networking.

Replacement Considerations

Consult official substitution lists for compatible upgrades within the Sitara family. Verify pin-to-pin compatibility if replacing existing designs. Ensure software drivers support the target replacement model's specific peripheral configurations.
