Product details
Overview
AM3351BZCE30 from Texas Instruments is a 300-MHz ARM Cortex-A8-based Sitara™ processor with 256KB L2 cache (ECC), 64KB on-chip RAM, 8-channel 12-bit SAR ADC, and single-port Gigabit Ethernet MAC (MII/RMII/RGMII). It integrates PRU-ICSS for real-time industrial protocols and targets cost-sensitive industrial HMI and automation controllers.
For engineers reviewing the AM3351BZCE30 datasheet, AM3351BZCE30 pinout, AM3351BZCE30 application, or AM3351BZCE30 equivalent, key selection factors include its 298-ball NFBGA (ZCE) package, 300-MHz fixed-frequency operation, absence of SGX530 graphics, limited PRU I/O pinout, and single USB 2.0 DRD port - distinguishing it from higher-tier AM335x variants.
Technical Context
The AM3351BZCE30 implements a single-core ARM Cortex-A8 CPU with NEON SIMD coprocessor, 32KB/32KB L1 instruction/data cache (parity), and 256KB L2 cache with ECC. Its memory subsystem supports LPDDR/DDR2/DDR3/DDR3L via a 16-bit EMIF with 1GB address space and includes GPMC for NAND/NOR/SRAM interfacing with BCH 4-/8-/16-bit ECC.
Real-time capability is delivered through the PRU-ICSS subsystem: two 200-MHz programmable RISC units with 8KB IRAM/DRAM each, 12KB shared RAM, and integrated peripherals including one UART, one eCAP, two MII Ethernet ports (one enabled), and MDIO - configured for EtherCAT, PROFINET, and other industrial protocols without host CPU intervention.

FAQ
What is the maximum operating frequency of the AM3351BZCE30?
The AM3351BZCE30 operates at a fixed 300 MHz - confirmed in TI's AM335x device comparison table (SPRS717L Table 3-1). Unlike higher-tier AM335x variants, it does not support dynamic voltage and frequency scaling (DVFS), ensuring deterministic timing for real-time industrial tasks without runtime frequency transitions. This fixed clock simplifies thermal design and EMI compliance in noise-sensitive environments.
Does the AM3351BZCE30 include a graphics accelerator?
No, the AM3351BZCE30 does not integrate the PowerVR SGX530 3D graphics engine. Per TI's device comparison (SPRS717L Table 3-1), graphics acceleration is omitted in the AM3351 variant - a deliberate cost and power optimization for non-graphical applications such as PLCs, gateways, and sensor concentrators. Display output relies solely on the integrated 24-bit LCD controller and DMA-driven raster engine.
How many Ethernet ports does the AM3351BZCE30 support?
The AM3351BZCE30 integrates one Gigabit Ethernet MAC (EMAC) with MII/RMII/RGMII interface support - verified in the device comparison table (SPRS717L Table 3-1) and functional block diagram. While the PRU-ICSS contains dual MII ports, only one is enabled and routed in the ZCE package; the second MII is reserved but not bonded out, limiting physical Ethernet connectivity to a single port.
What package type and ball count does the AM3351BZCE30 use?
The AM3351BZCE30 uses a 298-ball NFBGA package with ZCE suffix, 0.65-mm ball pitch, and 13.0 mm × 13.0 mm body size - explicitly documented in TI's mechanical packaging section (SPRS717L Section 9.2) and device information table. This Via Channel package enables high-density routing and thermal performance suitable for industrial PCBs with constrained layer counts.
Is the PRU-ICSS fully functional on the AM3351BZCE30?
Yes, the PRU-ICSS subsystem is fully implemented on the AM3351BZCE30, including both 200-MHz PRUs, 12KB shared RAM, and integrated peripherals (UART, eCAP, MII, MDIO). However, TI documentation confirms "ZCE: Limited PRU I/Os pinned out" - meaning fewer PRU-accessible GPIOs are exposed versus ZCZ packages, restricting direct pin-level real-time control but preserving protocol engine functionality for EtherCAT and PROFINET.
