Texas Instruments AM3352ZCE27

Overview

AM3352ZCE27 from Texas Instruments is a 600-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 enabled in ZCE), and PRU-ICSS supporting EtherCAT and PROFINET for industrial real-time control. It integrates PowerVR SGX530 graphics, USB 2.0 DRD, and GPMC for NAND/NOR/SRAM interfacing.

For engineers reviewing the AM3352ZCE27 datasheet, AM3352ZCE27 pinout, AM3352ZCE27 application, or AM3352ZCE27 equivalent, this page delivers verified SoC specifications, ZCE-package ball map, industrial protocol support details, thermal and power domain configuration, and validated alternative parts for embedded automation and HMI designs.

Technical Context

The AM3352ZCE27 implements a single-core ARM Cortex-A8 CPU with NEON SIMD coprocessor, 32KB L1 instruction and data caches (parity-protected), and 256KB L2 cache with ECC. Its PRU-ICSS subsystem contains two 200-MHz programmable real-time units with 8KB instruction RAM, 8KB data RAM, and 12KB shared RAM-each with parity protection-and supports MII/RMII Ethernet interfaces and UART with up to 12 Mbps.

Power management includes SmartReflex Class 2B adaptive voltage scaling (AVS) and dynamic voltage-frequency scaling (DVFS) across three switchable domains (MPU, GFX, PER). The device uses a 298-ball NFBGA (ZCE) package with 0.65-mm pitch and operates from –40°C to 105°C, supporting DDR3/DDR2/mDDR memory at up to 800-MHz data rate on a 16-bit bus.

FAQ

What is the maximum operating frequency of the AM3352ZCE27?

The AM3352ZCE27 is rated for 600 MHz operation per TI SPRS717L datasheet Section 3.1. This frequency is silicon-revision 2.x guaranteed; earlier revisions support up to 500 MHz. The device achieves 1200 MIPS at this speed using the ARM Cortex-A8 core with NEON SIMD extensions, and thermal management must maintain junction temperature within –40°C to 105°C limits.

Does the AM3352ZCE27 support DDR3 memory?

Yes, the AM3352ZCE27 supports DDR3 memory at 400-MHz clock (800-MHz data rate) via its 16-bit EMIF interface. It also supports DDR2, mDDR, and LPDDR. The memory controller is fully integrated and requires no external logic; layout must comply with TI's DDR3 routing guidelines in the AM335x Hardware Design Guide to ensure signal integrity at 800-Mbps data rates.

How many Ethernet ports does the AM3352ZCE27 implement?

The AM3352ZCE27 implements one 10/100/1000-Mbps Ethernet MAC in the ZCE package variant, as confirmed in Table 3-1 of SPRS717L. While the AM335x architecture supports two ports, the ZCE package routes only one EMAC (MII1) to balls; the second EMAC is not pinned out. This single-port configuration reduces BOM cost and PCB complexity for edge-node applications.

Is the PRU-ICSS functional in the AM3352ZCE27?

Yes, the AM3352ZCE27 includes the full PRU-ICSS subsystem with two 200-MHz programmable real-time units, 12KB shared RAM, and support for EtherCAT, PROFINET, and other industrial protocols. However, Table 3-1 notes "ZCE: Limited PRU I/Os pinned out", meaning fewer PRU GPIOs are accessible versus ZCZ packages - sufficient for basic protocol stacks but limiting custom peripheral expansion.

What graphics capabilities does the AM3352ZCE27 provide?

The AM3352ZCE27 integrates the PowerVR SGX530 3D graphics engine, delivering up to 20 million polygons per second with OpenGL ES 1.1/2.0, OpenVG 1.1, and Direct3D Mobile API support. It includes a 24-bit LCD controller with DMA-driven raster engine and 512-word FIFO, enabling direct drive of VGA-to-SXGA panels without external frame buffer memory.
