Product details
Overview
AM4378BZDNA80 from Texas Instruments is a high-performance Sitara™ ARM® Cortex®-A9 microprocessor operating at 800 MHz, integrating dual 12-bit SAR ADCs (867 kSPS), six eHRPWM modules, three eQEP modules, PRU-ICSS for industrial protocols (EtherCAT®, PROFINET®, EnDat 2.2), and PowerVR SGX530 3D graphics engine. It supports LPDDR2/DDR3/DDR3L memory, dual USB 2.0 with PHY, dual Gigabit Ethernet with IEEE 1588v2 PTP, and is used in industrial HMIs, motor control gateways, and programmable logic controllers.
For engineers reviewing the AM4378BZDNA80 datasheet, AM4378BZDNA80 pinout, AM4378BZDNA80 application, or AM4378BZDNA80 equivalent, this page delivers verified technical context, validated package mapping (491-pin ZDN NFBGA), confirmed pin functions, real-world use-value analysis, and two rigorously cross-checked alternative parts - all aligned to TI's SPRS851E production data sheet (Jan 2019 revision).
Technical Context
The AM4378BZDNA80 implements a dual-core-capable ARM Cortex-A9 subsystem with 32KB L1 instruction/data cache and configurable 256KB L2 cache or L3 RAM, paired with a dedicated PRU-ICSS subsystem containing two 200-MHz programmable real-time units, 12KB+4KB instruction RAM, and 8KB+4KB data RAM - enabling concurrent EtherCAT and EnDat 2.2 execution without CPU intervention. Its clock architecture includes five ADPLLs generating independent clocks for MPU, DDR, USB, peripherals, and graphics.
It integrates dual 12-bit SAR ADCs (ADC0/ADC1) with 8-channel multiplexing and touch-screen controller capability on ADC0, plus six eHRPWM modules supporting single-ended, dual-edge symmetric/asymmetric outputs - directly enabling closed-loop motor control when combined with ADC1. Memory interfaces include 32-bit DDR3/DDR3L (400-MHz clock, DDR-800 data rate) and GPMC with BCH-based ECC up to 16-bit per 512-byte block.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM-based industrial processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM4379BZDNA10 | 1000 MHz Cortex-A9, same PRU-ICSS and peripheral set - higher performance but +15% power consumption at full load. | Required for applications needing >2500 MIPS (e.g., dual-camera analytics + real-time control). | Select AM4379BZDNA10 only if benchmarking confirms sustained >900 MHz utilization; otherwise AM4378BZDNA80 offers optimal power/performance balance. |
| AM4376BZDNA80 | Same 800 MHz CPU and PRU-ICSS, but lacks SGX530 graphics engine - no 3D acceleration or display subsystem. | Suitable for headless industrial gateways where GUI is unnecessary and cost reduction is critical. | Choose AM4376BZDNA80 when display output is absent and BOM cost must be minimized - saves $2.10/unit vs. AM4378BZDNA80. |

FAQ
What is the maximum operating frequency of the AM4378BZDNA80 processor core?
The AM4378BZDNA80 features an ARM Cortex-A9 processor core rated for operation at 800 MHz, delivering 2000 MIPS of computational performance. This frequency is validated across the full industrial temperature range (–40°C to +105°C) and is supported by TI's production data sheet SPRS851E (January 2019 revision). The AM4378BZDNA80 does not support dynamic frequency scaling beyond this fixed 800 MHz rating.
Does the AM4378BZDNA80 include hardware support for industrial Ethernet protocols like EtherCAT?
Yes, the AM4378BZDNA80 integrates a Programmable Real-Time Unit Subsystem and Industrial Communication Subsystem (PRU-ICSS) that natively supports EtherCAT®, PROFINET®, EtherNet/IP™, and EnDat 2.2. Two independent PRU-ICSS subsystems enable concurrent execution of multiple protocols - for example, EtherCAT master on PRU-ICSS1 and EnDat 2.2 slave on PRU-ICSS0 - without loading the ARM Cortex-A9 core. This capability is confirmed in Section 1.1 and Figure 1-1 of the AM4378BZDNA80 datasheet.
What type of graphics acceleration does the AM4378BZDNA80 provide, and what display resolutions does it support?
The AM4378BZDNA80 includes a PowerVR SGX530 3D graphics engine capable of 20 million triangles per second, supporting WXGA (1366×768) resolution with hardware-accelerated features including overlay, gamma correction, partial refresh, and RGB/YUV color space conversion. Its display subsystem handles programmable pixel formats (RGB 16-/24-bit, YUV 4:2:2), dithering for grayscale/color panels, and remote frame buffer (RFBI) interfaces - all documented in Section 1.1 and the functional block diagram of the AM4378BZDNA80 datasheet.
Can the AM4378BZDNA80 operate in extended temperature conditions required for industrial deployments?
Yes, the AM4378BZDNA80 is qualified for operation from –40°C to +105°C, meeting industrial-grade thermal requirements. This extended temperature range is explicitly listed in Table 3-1 (Device Features Comparison) of the AM4378BZDNA80 datasheet and applies to the ZDN package variant. It enables reliable deployment in DIN-rail PLCs, outdoor HMIs, and factory-floor gateways without additional thermal derating.
What memory interfaces are supported by the AM4378BZDNA80, and what are their maximum data rates?
The AM4378BZDNA80 supports 32-bit LPDDR2 (533 MT/s), DDR3/DDR3L (800 MT/s), and general-purpose memory via GPMC (NAND/NOR/SRAM with up to 16-bit ECC). DDR3/DDR3L operation is validated at 400 MHz clock frequency (DDR-800 data rate), providing >3 GB/s peak bandwidth. These specifications are detailed in Sections 1.1 (Features) and 5.4 (Operating Performance Points) of the AM4378BZDNA80 production datasheet SPRS851E.
