Texas Instruments AM3354ZCZ80

Overview

AM3354ZCZ80 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 with integrated switch, and PRU-ICSS supporting EtherCAT and PROFINET - deployed in industrial HMIs and programmable logic controllers.

For engineers reviewing the AM3354ZCZ80 datasheet, AM3354ZCZ80 pinout, AM3354ZCZ80 application, or AM3354ZCZ80 equivalent, this page delivers verified technical context, package mapping, real-time subsystem capabilities, memory interface specs, and validated alternative options for industrial embedded design.

Technical Context

The AM3354ZCZ80 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 3D graphics engine and a dedicated 64KB OCMC RAM accessible by all masters with retention support.

Its PRU-ICSS contains two independent 200-MHz 32-bit RISC processors, each with 8KB instruction and 8KB data RAM (parity-protected), 12KB shared RAM, and peripherals including dual MII Ethernet ports, UART, eCAP, and MDIO - enabling deterministic real-time protocol offload without CPU intervention.

FAQ

What is the maximum operating frequency of the AM3354ZCZ80?

The AM3354ZCZ80 is factory-configured for 300 MHz operation. Unlike higher-grade variants such as AM3356ZCZ or AM3358ZCZ, it does not support dynamic voltage and frequency scaling (DVFS) and maintains fixed-frequency execution for deterministic timing in industrial control applications. This frequency is guaranteed across the full –40°C to 125°C industrial extended temperature range.

Does the AM3354ZCZ80 include PRU-ICSS functionality?

Yes, the AM3354ZCZ80 includes the full Programmable Real-Time Unit Subsystem and Industrial Communication Subsystem (PRU-ICSS) with two 200-MHz PRUs, 12KB shared RAM, dual MII Ethernet ports, UART, eCAP, and MDIO - enabling EtherCAT, PROFINET, and other real-time industrial protocols without ARM core involvement.

What memory types does the AM3354ZCZ80 support via its EMIF?

The AM3354ZCZ80 supports mDDR (LPDDR), DDR2, DDR3, and DDR3L through its 16-bit External Memory Interface (EMIF), with clock rates up to 400 MHz (800-MHz data rate) and 1GB total addressable space. It also integrates a General-Purpose Memory Controller (GPMC) for NAND/NOR/SRAM with BCH-based ECC up to 16-bit per 512-byte block.

Is the AM3354ZCZ80 pin-compatible with other AM335x ZCZ-package devices?

Yes, the AM3354ZCZ80 shares identical 324-ball NFBGA (ZCZ) mechanical packaging, ball pitch (0.80 mm), and pinout with AM3356ZCZ, AM3357ZCZ, AM3358ZCZ, and AM3359ZCZ - enabling drop-in replacement in existing PCB layouts when upgrading CPU frequency or peripheral features.

What graphics capabilities does the AM3354ZCZ80 provide?

The AM3354ZCZ80 integrates the PowerVR SGX530 3D graphics engine capable of rendering up to 20 million polygons per second, supporting Direct3D Mobile, OpenGL ES 1.1/2.0, and OpenMAX APIs. Its 24-bit LCD controller drives resolutions up to 2048×2048 with a 126-MHz pixel clock and built-in DMA engine for zero-CPU-framebuffer updates.
