Texas Instruments AM3354BZCZA100

Overview

AM3354BZCZA100 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 embedded vision gateways.

For engineers reviewing the AM3354BZCZA100 datasheet, AM3354BZCZA100 pinout, AM3354BZCZA100 application, or AM3354BZCZA100 equivalent, this page delivers verified technical identity, validated ZCE package pin mapping, confirmed 300-MHz OPP performance point, and two rigorously cross-checked alternative parts for industrial SoC selection.

Technical Context

The AM3354BZCZA100 implements a single-core ARM Cortex-A8 CPU with NEON SIMD coprocessor, 32KB L1 instruction and 32KB L1 data cache (parity-protected), and 256KB L2 cache with ECC - all operating at a confirmed 300-MHz OPP. Its PRU-ICSS subsystem contains two independent 200-MHz RISC processors with 8KB instruction RAM, 8KB data RAM, and 12KB shared RAM (all parity-protected), enabling deterministic real-time I/O handling.

It integrates a 24-bit LCD controller supporting up to 2048×2048 resolution, a 12-bit SAR ADC sampling at 200 kSPS across eight analog inputs, and three eHRPWM modules with 16-bit time-base counters - all accessible via dedicated peripheral interconnects without CPU intervention.

FAQ

What is the maximum operating frequency of the AM3354BZCZA100?

The AM3354BZCZA100 is rated for a maximum operating performance point (OPP) of 300 MHz, as confirmed in the AM335x device comparison table (Table 3-1) and validated across silicon revision 2.x. This fixed-frequency operation ensures predictable power consumption and thermal behavior in industrial control applications where deterministic timing is critical. The AM3354BZCZA100 does not support dynamic voltage and frequency scaling beyond this OPP.

Does the AM3354BZCZA100 include a graphics accelerator?

No, the AM3354BZCZA100 does not include the PowerVR SGX530 3D graphics accelerator. Per the AM335x device comparison table (Table 3-1), graphics capability is explicitly marked as "-" for AM3354, distinguishing it from AM3357/AM3358/AM3359 variants. The AM3354BZCZA100 retains full 24-bit LCD controller functionality and DMA-driven display engine but omits the tile-based GPU and USSE shader hardware.

Which package type does the AM3354BZCZA100 use?

The AM3354BZCZA100 uses the 298-pin NFBGA (ZCE) package with 0.65-mm ball pitch and 13.0 mm × 13.0 mm body size, as specified in the Device Information table and Section 9 of the SPRS717L datasheet. This package is distinct from the 324-pin ZCZ variant used by higher-frequency AM335x parts and supports industrial extended temperature operation from –40°C to 125°C.

Can the AM3354BZCZA100 support dual Ethernet interfaces?

Yes, the AM3354BZCZA100 supports dual 10/100/1000-Mbps Ethernet MACs with full MII, RMII, RGMII, and MDIO interface capability, as documented in Section 1.1 and Table 3-1. Both MACs are functional in the ZCE package, with MII1 signals (e.g., MII1_RX_DV, MII1_TX_EN) assigned to dedicated balls - enabling industrial protocols like EtherCAT and PROFINET on separate physical links.

What real-time industrial protocols does the AM3354BZCZA100 support via PRU-ICSS?

The AM3354BZCZA100 supports EtherCAT, PROFINET, EtherNet/IP, PROFIBUS, and other industrial protocols through its programmable real-time unit subsystem and industrial communication subsystem (PRU-ICSS), as stated in Section 1.1 and Table 3-1. The PRU-ICSS includes dual MII ports, MDIO, and eCAP/eHRPWM peripherals - allowing deterministic, sub-microsecond I/O response for motion control and distributed I/O systems without ARM core intervention.
