AM4376BZDNA80

Overview

The AM4376BZDNA80 is a microprocessor from the Texas Instruments Sitara family, featuring an ARM Cortex-A9 core. It operates at a maximum clock frequency of 800 MHz and utilizes a BGA-491 package. The device includes 32 kB L1 instruction and data caches, alongside a 256 kB L2 cache. It supports multiple I/O voltages including 1.2 V, 1.35 V, 1.5 V, 1.8 V, and 3.3 V. Interfaces encompass CAN, Ethernet, I2C, SPI, UART, and USB. The processor functions within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates Programmable Real-Time Unit and Industrial Communication Subsystem (PRU-ICS) for deterministic control tasks.
• Supports floating-point operations via the ARM Cortex-A9 architecture.
• Provides versatile connectivity through integrated Ethernet, USB, and industrial communication interfaces.

Applications

• Industrial automation controllers
• Human-machine interface (HMI) displays
• Smart grid energy management systems

Procurement Notes

Verify the specific suffix DNA80 against official datasheets to confirm pinout and thermal specifications. Ensure compatibility with required operating voltage levels and interface configurations. Confirm RoHS compliance status through manufacturer documentation before integration into final designs.

Selection Notes

Select this component when deterministic real-time processing is required alongside general-purpose computing. The inclusion of PRU-ICS allows offloading time-critical tasks from the main CPU. Evaluate memory requirements against the available cache sizes and external memory controller capabilities.

Part Context

This part belongs to the AM437x Sitara series, designed for cost-sensitive embedded applications. It shares architectural similarities with other members like the AM4378 but offers specific performance and feature sets tailored for industrial and commercial markets. The BGA-491 package facilitates compact board designs.

Replacement Considerations

Consult official substitution guides for compatible alternatives within the Sitara family. Verify electrical and pinout compatibility before replacing existing components in established designs.
