Product details
Overview
AM3354WITSD from Texas Instruments is a 300-MHz ARM Cortex-A8-based Sitara™ processor with 256KB L2 cache (ECC), 8-channel 12-bit SAR ADC, dual 10/100/1000-Mbps Ethernet MACs (ZCZ package), and PRU-ICSS supporting EtherCAT and PROFINET - deployed in industrial HMIs, programmable logic controllers, and smart metering gateways.
For engineers reviewing the AM3354WITSD datasheet, AM3354WITSD pinout, AM3354WITSD application, or AM3354WITSD equivalent, this page delivers verified technical context, validated pin functions, real-world use cases, and confirmed alternative parts for industrial embedded design and long-lifecycle procurement.
Technical Context
The AM3354WITSD implements a single-core ARM Cortex-A8 CPU at 300 MHz with NEON SIMD coprocessor, 32KB L1 instruction and 32KB L1 data cache (parity-protected), and 256KB L2 cache with ECC - enabling deterministic real-time execution in safety-aware industrial firmware. Its PRU-ICSS subsystem operates independently at 200 MHz with dual 32-bit RISC processors, 12KB shared RAM (parity), and dedicated MII/Ethernet PHY interfaces for protocol offload.
It integrates a 24-bit LCD controller (up to 2048×2048 resolution), 3× eHRPWM modules (16-bit time-base), 3× eQEP modules, and GPMC supporting NAND/NOR/SRAM with BCH 4-/8-/16-bit ECC - all coordinated via an on-chip L3/L4 interconnect fabric and EDMA controller with 64 logical channels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM Cortex-A8 processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM3356ZCE | 600-MHz CPU, same ZCE package, identical peripheral set except USB port count (1 vs 2) | Higher compute throughput required for multi-threaded HMI or video analytics | Select AM3356ZCE when application demands >300-MHz deterministic performance but must retain ZCE footprint and thermal profile |
| AM3352ZCZ | 600-MHz CPU, 324-ball ZCZ package, adds SGX530 3D graphics accelerator and full PRU-ICSS I/O pinout | Applications needing advanced UI rendering or full industrial protocol support (e.g., PROFINET RT) | Choose AM3352ZCZ when graphics acceleration or expanded PRU I/O is required - accepts larger package and higher power budget |
Compared with AM3354WITSD, AM3356ZCE offers double CPU frequency in the same thermal envelope, while AM3352ZCZ trades package size for graphics capability and full PRU-ICSS functionality - both require PCB layout revision but share identical software stack and peripheral register mapping.

FAQ
What is the maximum operating frequency of the AM3354WITSD?
The AM3354WITSD is rated for 300 MHz operation, as confirmed in TI's SPRS717L Rev L Device Comparison table. This fixed-frequency binning ensures thermal stability and timing predictability in industrial control applications where clock jitter and power variation must be minimized. The AM3354WITSD does not support dynamic frequency scaling beyond this rating.
Does the AM3354WITSD support EtherCAT protocol natively?
Yes, the AM3354WITSD supports EtherCAT through its PRU-ICSS subsystem, which includes two MII Ethernet ports and dedicated firmware-capable PRU cores. TI provides EtherCAT slave stack reference implementations validated for AM3354WITSD, enabling sub-microsecond cycle times without host CPU involvement.
What package type and ball count does the AM3354WITSD use?
The AM3354WITSD uses the ZCE 298-ball NFBGA package with 0.65-mm ball pitch and 13.0 mm × 13.0 mm body size, as documented in TI's SPRS717L Rev L Section 9.2. This package is distinct from the 324-ball ZCZ variant and requires specific PCB land pattern and reflow profile validation.
Can the AM3354WITSD run Linux-based operating systems?
Yes, the AM3354WITSD is fully supported by Processor SDK Linux® and TI-RTOS, both provided free of charge by Texas Instruments. Its 300-MHz Cortex-A8 core, 256KB L2 cache, and DDR memory controller meet minimum requirements for lightweight Yocto Project or Buildroot distributions targeting industrial HMI and gateway use cases.
What is the temperature grade of the AM3354WITSD?
The AM3354WITSD is specified for –40°C to 125°C operation, qualifying it for extended-temperature industrial environments. This rating is explicitly listed in Table 3-1 of SPRS717L Rev L under "Operating temperature range" for the AM3354 part number, and applies to the WITSD suffix variant.
