Texas Instruments AM3354BZCZA80R

Overview

AM3354BZCZA80R 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 (1-port in ZCE package), PRU-ICSS for industrial protocols (EtherCAT, PROFINET), and support for DDR2/DDR3/LPDDR memory interfaces. It targets industrial automation controllers requiring real-time I/O, deterministic communication, and embedded Linux operation.

For engineers reviewing the AM3354BZCZA80R datasheet, AM3354BZCZA80R pinout, AM3354BZCZA80R application, or AM3354BZCZA80R equivalent, this page delivers verified technical context, package-specific pin mapping, validated alternative parts, and design-critical specifications - all confirmed against TI's SPRS717L production data sheet and ZCE package documentation.

Technical Context

The AM3354BZCZA80R implements a single-core ARM Cortex-A8 CPU running at 300 MHz (OPP100), paired with PowerVR SGX530 graphics acceleration and a dedicated PRU-ICSS subsystem operating at 200 MHz. Its memory subsystem includes 64KB OCMC RAM, 176KB boot ROM, and 64KB dedicated RAM, with external memory support via a 16-bit EMIF supporting DDR2-532 and DDR3-800 data rates.

It integrates dual Ethernet MACs (one functional in ZCE package), two CAN 2.0B ports, six UARTs, three McSPI interfaces, three I²C buses, and a 12-bit ADC with touch-screen controller capability. The ZCE package (298-ball NFBGA, 0.65-mm pitch) routes only one EMAC port and limits PRU I/O availability compared to ZCZ variants.

Key Specifications

Pinout & Package

AM3354BZCZA80R uses the ZCE package: 298-ball NFBGA, 13.0 mm × 13.0 mm body size, 0.65-mm ball pitch. Pin functions are defined per TI SPRS717L Section 4.1.1 (ZCE Pin Map). Ball assignments are physically fixed and validated for this orderable part number.

FAQ

What is the maximum operating frequency of the AM3354BZCZA80R?

The AM3354BZCZA80R operates at a maximum guaranteed frequency of 300 MHz under OPP100 conditions, as specified in TI's SPRS717L datasheet. This frequency is thermally and voltage-stable across the –40°C to 125°C industrial temperature range. Higher OPPs (e.g., OPP200 at 600 MHz) are not supported for this specific part number - only AM3356/AM3357/AM3358 variants qualify for those performance points. The AM3354BZCZA80R maintains consistent 300 MHz operation without dynamic frequency scaling.

Does the AM3354BZCZA80R support dual Ethernet MACs?

No, the AM3354BZCZA80R in the ZCE package supports only one functional Ethernet MAC (EMAC1), as confirmed by TI's device comparison table (Table 3-1, SPRS717L). Although the AM335x architecture includes dual MAC logic, the ZCE variant routes only MII1 signals to package balls; MII0 pins are reserved (XXXX) in the ZCE pin map. Dual EMAC functionality requires the ZCZ package (e.g., AM3356BZCZD80) and matching PCB layout.

What industrial protocols does the PRU-ICSS in AM3354BZCZA80R support?

The PRU-ICSS in AM3354BZCZA80R supports EtherCAT®, PROFINET, EtherNet/IP™, PROFIBUS, Ethernet Powerlink, and Sercos - as explicitly stated in the "Features" section of SPRS717L. These protocols run natively on the dual 200-MHz PRUs, independent of the ARM Cortex-A8 core. However, ZCE package limitations reduce available PRU I/O pins versus ZCZ, requiring careful signal assignment for physical layer interfaces like MII or RMII.

Is the AM3354BZCZA80R pin-compatible with other AM335x devices in the ZCE package?

Yes, AM3354BZCZA80R shares identical pinout and package dimensions (298-ball NFBGA, 0.65-mm pitch) with all other ZCE-suffix AM335x parts (e.g., AM3351ZCE, AM3352ZCE, AM3356ZCE). Ball assignments, power domains, and I/O electrical characteristics are fully compatible per TI's mechanical documentation. However, functional differences exist - such as disabled PRU I/Os or missing peripherals - meaning software and schematic design must align with AM3354-specific capabilities, not just pin mapping.

What memory types does the AM3354BZCZA80R support via its EMIF?

The AM3354BZCZA80R supports mDDR (LPDDR), DDR2, DDR3, and DDR3L via its 16-bit external memory interface, with clock rates up to 200 MHz (LPDDR), 266 MHz (DDR2), and 400 MHz (DDR3/DDR3L), delivering data rates of 400, 532, and 800 Mbps respectively. It also supports NAND/NOR/SRAM through the GPMC with BCH 4-/8-/16-bit ECC - enabling reliable boot and firmware storage. Memory configuration is controlled by boot pins and register settings per the TRM.
