AM4376BZDN100

Overview

The AM4376BZDN100 is a microprocessor from the Texas Instruments Sitara family, featuring an ARM Cortex-A9 core operating at a maximum clock frequency of 1000 MHz. It utilizes a 32-bit data bus and is housed in a 491-ball BGA package. The device includes 32 kB L1 instruction and data caches, along with 256 kB of L2 cache or L3 RAM. It supports LPDDR2, DDR3, and DDR3L external memory interfaces and integrates a SGX530 graphics engine. Power supply requirements include 1.26 V for core operation, with I/O voltages supporting 1.2 V, 1.35 V, 1.5 V, 1.8 V, and 3.3 V levels.

Feature Summary

• Integrates a programmable real-time unit subsystem and industrial communication subsystem (PRU-ICS) for deterministic control tasks.
• Includes a dedicated SGX530 graphics engine and display subsystem for multimedia processing.
• Features hardware security accelerators supporting AES, SHA, RNG, DES, and 3DES encryption standards.
• Provides multiple high-speed serial interfaces including Ethernet, USB 2.0, CAN, UART, SPI, and I2C.

Applications

• Industrial automation controllers requiring real-time processing capabilities.
• Human-machine interface (HMI) displays utilizing integrated graphics support.
• Smart energy management systems and smart grid infrastructure devices.
• Medical equipment requiring secure data handling and reliable connectivity.

Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm voltage grades and temperature ranges. Ensure compatibility with required memory types such as LPDDR2 or DDR3L during board design. Confirm moisture sensitivity level handling procedures are followed during assembly. Cross-reference pinouts with the latest package drawing to avoid layout errors.

Selection Notes

Select this component when a single-core ARM Cortex-A9 solution with PRU-ICS is required for deterministic applications. Consider the 1 GHz processing speed for performance-intensive HMI tasks. Evaluate the integrated graphics engine if graphical output is necessary without external GPUs. Check I/O voltage flexibility to simplify power domain design across different peripheral interfaces.

Part Context

This processor 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 allows for compact system designs while maintaining robust connectivity options for various peripheral interfaces.

Replacement Considerations

The AM4376BZDNA100 serves as a lower-frequency variant within the same package family compared to the AM4379BZDNA100. Designers may consider the AM4376BZDNA80 for applications requiring reduced power consumption at 800 MHz. Verify software compatibility and pinout equivalence before substituting with other AM437x family members.
