Product details
Overview
AM3351BZCE60R from Texas Instruments is a 300-MHz ARM Cortex-A8-based Sitara™ processor with 256KB L2 cache (ECC), 64KB OCMC RAM, 8-channel 12-bit SAR ADC, and PRU-ICSS supporting industrial protocols including EtherCAT and PROFIBUS - deployed in smart toll systems and connected vending machines.
For engineers reviewing the AM3351BZCE60R datasheet, AM3351BZCE60R pinout, AM3351BZCE60R application, or AM3351BZCE60R equivalent, this page delivers verified technical context, package mapping, validated pin functions, real-world use cases, and two confirmed alternative parts for industrial embedded design.
Technical Context
The AM3351BZCE60R implements a single-core ARM Cortex-A8 CPU running at 300 MHz with NEON SIMD coprocessor, 32KB/32KB L1 instruction/data cache (parity), and 256KB L2 cache with ECC. It integrates PowerVR SGX530 graphics acceleration and a dedicated PRU-ICSS subsystem with two 200-MHz programmable real-time units, 8KB instruction RAM, 8KB data RAM, and 12KB shared RAM - all with single-error detection.
Its memory subsystem includes a 16-bit DDR2/DDR3/mDDR EMIF supporting up to 1GB address space, GPMC for NAND/NOR/SRAM, and on-chip boot ROM (176KB) plus 64KB dedicated RAM. The device supports IEEE 1588v1 PTP, dual USB 2.0 DRD ports (ZCE package limits to one), and two industrial Ethernet MACs (one port enabled in ZCE).

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 |
|---|---|---|---|
| AM3352BZCZ60 | 324-pin ZCZ package, 600 MHz max frequency, dual Ethernet MACs, full USB 2.0 DRD support | Requires larger PCB footprint and higher power budget; suitable for designs needing dual gigabit Ethernet and higher compute throughput | Select when system demands >300 MHz performance, second Ethernet port, or USB device/host flexibility not available in ZCE variant |
| AM3354BZCE60 | Same ZCE package and 300 MHz speed, but adds SGX530 3D graphics accelerator and full PRU-ICSS I/O pinout | Enables richer GUI rendering and broader industrial protocol support (e.g., PROFINET, EtherNet/IP) via additional PRU pins | Choose if display-intensive HMI or expanded real-time I/O (beyond AM3351's limited PRU pin count) is required |
Compared with AM3351BZCE60R, AM3352BZCZ60 offers higher clock rate and dual Ethernet but increases board area and thermal management complexity, while AM3354BZCE60 retains identical packaging and speed but adds graphics and full PRU I/O - making it ideal for HMIs requiring both real-time control and visual feedback.

FAQ
What is the maximum operating frequency of the AM3351BZCE60R?
The AM3351BZCE60R operates at a fixed 300 MHz CPU frequency. Unlike higher-tier AM335x variants, it does not support Dynamic Voltage and Frequency Scaling (DVFS); its clock tree is configured for stable, low-power operation without runtime frequency adjustment. This simplifies thermal design and power regulation for cost-sensitive industrial deployments where peak performance is not required.
Does the AM3351BZCE60R support secure boot functionality?
The AM3351BZCE60R includes hardware crypto accelerators (AES, SHA, RNG) and supports optional secure boot, but implementation requires custom part engagement with Texas Instruments and provisioning of cryptographic keys during manufacturing. Standard configurations ship without pre-provisioned keys, and secure boot must be enabled via fuse programming and signed bootloader configuration - not active by default.
How many Ethernet ports are accessible on the AM3351BZCE60R?
The AM3351BZCE60R exposes one functional Ethernet MAC port (MII1) in its ZCE package, despite containing dual EMAC hardware. The second MAC (MII0) is not bonded out due to pin count limitations in the 298-ball NFBGA. Designers requiring dual Ethernet must select a ZCZ-package variant (e.g., AM3352BZCZ60) or implement external PHY bridging.
Can the AM3351BZCE60R drive a high-resolution LCD display?
Yes, the AM3351BZCE60R integrates a 24-bit RGB LCD controller supporting resolutions up to 2048×2048 with a maximum 126-MHz pixel clock. Its internal DMA engine fetches frame buffer data directly from external memory without CPU intervention, enabling smooth video playback and responsive GUI rendering - provided external DDR bandwidth and PCB layout meet timing requirements.
What industrial communication protocols does the PRU-ICSS in AM3351BZCE60R support?
The PRU-ICSS in AM3351BZCE60R supports EtherCAT, PROFIBUS, PROFINET, EtherNet/IP, and other real-time industrial protocols via firmware-loaded state machines. However, due to limited PRU I/O pin count in the ZCE package, full physical layer support (e.g., dual Ethernet PHYs or isolated CAN transceivers) requires external components - the PRU handles protocol stack execution, not direct PHY interfacing.
