Product details
Overview
AM4379BZDNA100 from Texas Instruments is a high-performance Sitara™ ARM® Cortex®-A9 processor operating at 1000 MHz, integrating dual 12-bit SAR ADCs (867 kSPS), six eHRPWM modules, three eQEP modules, and dual 1-Gbps Ethernet MACs with IEEE 1588v2 support. It features PRU-ICSS for real-time industrial protocols including EtherCAT and PROFINET, and PowerVR SGX530 3D graphics (20 MTri/s) for rich UI in industrial HMIs.
For engineers reviewing the AM4379BZDNA100 datasheet, AM4379BZDNA100 pinout, AM4379BZDNA100 application, or AM4379BZDNA100 equivalent, this device is selected for deterministic real-time control, embedded vision, and secure HMI applications requiring integrated ADC, PWM, encoder, and industrial Ethernet capabilities - not generic microcontrollers or low-end SoCs.
Technical Context
The AM4379BZDNA100 implements a dual-core-capable ARM Cortex-A9 subsystem with 32KB L1 instruction/data cache and 256KB configurable L2 cache or L3 RAM, paired with a dedicated PRU-ICSS subsystem containing two 200-MHz programmable real-time units supporting parallel EtherCAT and EnDat execution. Its memory architecture includes 32-bit LPDDR2/DDR3/DDR3L interfaces (up to DDR-800 data rate) and GPMC with BCH-based 16-bit ECC for NAND/NOR/SRAM.
Real-time I/O is enabled via six eHRPWM modules (16-bit time-base, dual-edge symmetric/asymmetric output), three eCAP modules, three eQEP modules, and two 12-bit SAR ADCs with 8-channel multiplexing - one configurable as a 4-/5-/8-wire resistive touch screen controller. Security includes crypto accelerators (AES, SHA, RNG) and secure boot (HS variant only).

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM4378BZDNA80 | 800 MHz CPU, same PRU-ICSS, identical peripheral set, but lower max frequency and reduced thermal envelope. | Suitable for cost-sensitive industrial gateways where 1000 MHz headroom is unnecessary. | Select when application workload fits within 800 MHz and thermal budget is constrained. |
| AM6442BOSME80 | ARM Cortex-A53 dual-core @ 800 MHz, C7x DSP, 2x PRU-ICSS, enhanced safety features (ISO 13849 PL d), no SGX530 graphics. | Targeted at functional-safety-certified robotics and motion controllers requiring ASIL-B compliance. | Choose for new designs requiring safety certification and DSP-accelerated signal processing over graphics. |
Compared with AM4378BZDNA80, AM4379BZDNA100 delivers 25% higher CPU throughput and improved thermal margin for sustained compute loads; versus AM6442BOSME80, it trades safety certification and DSP for mature graphics and broader industrial protocol support in non-safety contexts.

FAQ
What is the maximum operating frequency of the AM4379BZDNA100 processor core?
The AM4379BZDNA100 features an ARM Cortex-A9 processor core rated for operation up to 1000 MHz. This frequency is validated under specified thermal and voltage conditions per TI's SPRS851E datasheet, and enables high-throughput execution of Linux-based HMI applications and real-time industrial protocol stacks on the AM4379BZDNA100.
Does the AM4379BZDNA100 support secure boot functionality?
Secure boot is available only on AM437x High-Security (HS) variants, which require specific fuse programming and are designated with an 'HS' suffix. The AM4379BZDNA100 is not an HS device and therefore does not support secure boot; cryptographic acceleration (AES, SHA, RNG) remains available for software-implemented security on the AM4379BZDNA100.
How many Ethernet ports does the AM4379BZDNA100 integrate, and what speeds are supported?
The AM4379BZDNA100 integrates two Ethernet MACs with an on-chip 2-port switch, supporting 10/100/1000 Mbps operation per port. Each MAC supports MII, RMII, and RGMII physical layer interfaces and includes IEEE 1588v2 hardware timestamping - essential for time-critical industrial networking on the AM4379BZDNA100.
Can the AM4379BZDNA100 directly interface with a resistive touch screen?
Yes - the AM4379BZDNA100 includes ADC0, which can be configured as a 4-, 5-, or 8-wire resistive touch screen controller (TSC). This capability eliminates the need for an external touch controller IC and enables direct integration of analog touch panels into HMI designs using the AM4379BZDNA100.
What package type and ball count does the AM4379BZDNA100 use?
The AM4379BZDNA100 uses a 491-ball NFBGA package (ZDN suffix), measuring 17.0 mm × 17.0 mm with 0.65-mm ball pitch. This package employs Via Channel Array technology to simplify PCB routing and reduce layer count - a verified mechanical specification documented in TI's SPRS851E datasheet for the AM4379BZDNA100.
