AM4378BZDN80

Overview

The AM4378BZDN80 is a microprocessor from the Texas Instruments Sitara family, built on an ARM Cortex-A9 core. It operates at a maximum clock frequency of 800 MHz and utilizes a BGA-491 package for surface mount installation. The device features integrated L1 and L2 caches, including 32 kB instruction and data memory for L1, and 256 kB for L2. It supports multiple I/O voltages ranging from 1.2 V to 3.3 V and functions within a temperature range of -40°C to +105°C. Interfaces include CAN, Ethernet, I2C, SPI, UART, and USB.

Feature Summary

• Integrates a PowerVR SGX graphics accelerator subsystem for 3D graphics acceleration and advanced user interface support.
• Includes a Programmable Real-Time Unit and Industrial Communication Subsystem (PRU-ICSS) for deterministic real-time processing independent of the main ARM core.
• Supports high-performance interconnects for high-bandwidth data transfer between internal/external memory controllers and on-chip peripherals.

Applications

• Industrial automation systems requiring EtherCAT or PROFINET protocols
• Human-machine interfaces with rich graphical displays
• Smart energy management devices

Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm pinout and feature set compatibility. Ensure the procurement channel provides original components with traceability. Check RoHS compliance status as indicated in official documentation before integration into regulated environments.

Selection Notes

Select this component when deterministic real-time control is required alongside complex graphical processing. The PRU-ICSS allows offloading time-critical tasks from the main processor. Consider the thermal performance and power requirements associated with the 800 MHz operation and industrial temperature range during system design.

Part Context

This part belongs to the AM437x series of high-performance processors designed for applications needing both Linux-based operating systems and real-time capabilities. It serves as an upgrade path for systems previously using lower-performance ARM cores, offering enhanced peripheral options like QSPI-NOR and LPDDR2 memory interfaces.

Replacement Considerations

Consult the official AM437x product page for confirmed substitute part numbers. Verify functional equivalence regarding the PRU-ICSS and graphics engine when considering alternatives within the Sitara family.
