Texas Instruments AM3354BZCZ80

Overview

AM3354BZCZ80 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 PROFIBUS for industrial real-time control in programmable logic controllers and HMIs.

For engineers reviewing the AM3354BZCZ80 datasheet, AM3354BZCZ80 pinout, AM3354BZCZ80 application, or AM3354BZCZ80 equivalent, this page delivers verified technical context, package mapping to 324-ball NFBGA (0.80-mm pitch), confirmed peripheral set (2×CAN, 6×UART, 3×eHRPWM), and validated alternatives for industrial SoC migration paths.

Technical Context

The AM3354BZCZ80 implements a single-core ARM Cortex-A8 CPU running at 300 MHz with NEON SIMD coprocessor, 32KB L1 instruction and 32KB L1 data cache (parity-protected), 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, 12KB shared RAM, and dual MII Ethernet ports for deterministic industrial protocol offload.

Its memory subsystem supports DDR2/DDR3/DDR3L (400-MHz clock, 800-MHz data rate) via a 16-bit EMIF, plus GPMC for NAND/NOR/SRAM with BCH 4-/8-/16-bit ECC. The device includes IEEE 1588v1 PTP support, dual CAN 2.0A/B controllers, and a 12-bit 200-kSPS ADC with touch-screen controller capability.

FAQ

What is the maximum operating frequency of the AM3354BZCZ80?

The AM3354BZCZ80 is factory-specified for 300 MHz operation, as confirmed in the AM335x device comparison table (Table 3-1). This fixed frequency reflects its industrial-grade silicon revision and thermal profile, distinguishing it from higher-speed variants like AM3356BZCZ60 (600 MHz) or AM3359BZCZ100 (1000 MHz). The AM3354BZCZ80 maintains consistent timing margins under –40°C to 105°C conditions without dynamic voltage scaling.

Does the AM3354BZCZ80 include a graphics accelerator?

No, the AM3354BZCZ80 does not include the PowerVR SGX530 graphics engine. Per Table 3-1 in the AM335x datasheet, graphics acceleration is only present in AM3354ZCE (via limited PRU I/Os) and higher variants (AM3357/AM3358/AM3359). The AM3354BZCZ80 retains full peripheral functionality-including dual Ethernet, PRU-ICSS, and 8-channel ADC-but omits the SGX530 block to reduce cost and power for non-GUI applications.

What package type and ball count does the AM3354BZCZ80 use?

The AM3354BZCZ80 uses a 324-ball NFBGA package with ZCZ suffix, 15.0 mm × 15.0 mm body size, and 0.80-mm ball pitch. This matches the mechanical specifications listed in Section 9 of the SPRS717L datasheet and is distinct from the 298-ball ZCE variant used in lower-I/O versions. The ZCZ package exposes a thermal pad on the underside for mandatory PCB thermal vias.

Which industrial Ethernet protocols does the AM3354BZCZ80 support natively?

The AM3354BZCZ80 supports EtherCAT, PROFINET, EtherNet/IP, PROFIBUS, and other industrial protocols through its PRU-ICSS subsystem-not the ARM core. The dual MII Ethernet ports and dedicated PRU firmware enable hardware-timed frame processing with sub-microsecond jitter. Protocol stacks run on the PRUs, freeing the Cortex-A8 for application tasks; no external protocol ASIC is required.

Is secure boot supported on the AM3354BZCZ80?

Secure boot is an optional feature for the AM3354BZCZ80 that requires custom part engagement with Texas Instruments. When enabled, it leverages on-chip crypto accelerators (AES, SHA, RNG) to authenticate firmware images during startup. The AM3354BZCZ80 includes all necessary hardware blocks, but production deployment depends on TI's secure provisioning process and customer-specific key management.
