Product details
Overview
AM4378BZDND80 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 EtherCAT/PROFINET, and PowerVR SGX530 3D graphics. It supports DDR3/DDR3L/LPDDR2 memory, dual USB 2.0 with PHY, dual Gigabit Ethernet with IEEE 1588v2, and industrial I/O including CAN, McSPI, UART, and I²C - deployed in programmable logic controllers and HMI terminals.
For engineers reviewing the AM4378BZDND80 datasheet, AM4378BZDND80 pinout, AM4378BZDND80 application, or AM4378BZDND80 equivalent, key selection criteria include its 800-MHz Cortex-A9 core, PRU-ICSS real-time protocol offload capability, dual 12-bit ADC with touch-screen controller mode, 491-ball NFBGA (ZDN) package, and industrial temperature range (–40°C to +105°C).
Technical Context
The AM4378BZDND80 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 for deterministic industrial protocol processing. Its memory architecture includes 32-bit DDR3/DDR3L/LPDDR2 interfaces (400-MHz clock / DDR-800 data rate) and GPMC supporting NAND/NOR/SRAM with up to 16-bit ECC.
Peripherals are partitioned across multiple clock domains: dual EMACs with integrated switch and IEEE 1588v2 support; two CAN 2.0B ports; six UARTs with IrDA/CIR; five McSPIs (up to 48 MHz); three I²C masters/slaves; and dual 12-bit SAR ADCs - one configurable as a 4-/5-/8-wire resistive touch-screen controller (TSC) with eight analog inputs.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM4379BZDND100 | 1000 MHz Cortex-A9, same peripherals and package - higher performance but increased power consumption and thermal requirements. | Suitable for compute-intensive HMI with multi-layer OpenGL ES 2.0 rendering or dual-display video playback. | Select when >2000 MIPS and full 1 GHz operation are required; verify thermal design and DDR timing margins. |
| AM4376BZDND80 | Same 800 MHz speed and ZDN package, but lacks SGX530 graphics engine and PRU-ICSS full feature set (basic industrial protocols only). | Targeted at non-graphical control applications where PRU-ICSS is used only for simple GPIO/bit-banging, not EtherCAT/PROFINET. | Choose for cost-sensitive industrial gateways or remote I/O concentrators without display or advanced real-time protocol needs. |
Compared with AM4379BZDND100, AM4378BZDND80 trades peak CPU frequency for lower thermal design power and identical PRU-ICSS capability; versus AM4376BZDND80, it adds full 3D graphics and enhanced PRU-ICSS protocol support - making it optimal for graphical HMIs with industrial Ethernet connectivity.

FAQ
What is the maximum operating frequency of the AM4378BZDND80?
The AM4378BZDND80 operates at a guaranteed maximum frequency of 800 MHz for the ARM Cortex-A9 processor core.

These accelerators operate independently of the Cortex-A9 core and are accessible via TI's Crypto Library and Linux kernel crypto API - enabling fast secure boot, encrypted filesystems, and TLS handshake acceleration in AM4378BZDND80-based systems.
Can the AM4378BZDND80 support resistive touch-screen functionality without external components?
Yes, the AM4378BZDND80 includes an integrated resistive touch-screen controller (TSC) within ADC0, supporting 4-, 5-, and 8-wire configurations with hardware sequencer, pen-down detection, and debounce filtering. This eliminates the need for external TSC ICs in HMI designs, reducing BOM cost and board space while maintaining compatibility with standard analog resistive overlays used in industrial panels.
