Product details
Overview
AM3352BZCZA100 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 (ZCZ package), and PRU-ICSS supporting EtherCAT and PROFINET - deployed in industrial HMIs and programmable logic controllers.
For engineers reviewing the AM3352BZCZA100 datasheet, AM3352BZCZA100 pinout, AM3352BZCZA100 application, or AM3352BZCZA100 equivalent, this page delivers verified technical context, validated package mapping, confirmed pin functions, and real-world use-value for industrial automation SoC selection.
Technical Context
The AM3352BZCZA100 implements a single-core ARM Cortex-A8 CPU running at 600 MHz with NEON SIMD coprocessor, 32KB L1 instruction and 32KB L1 data cache (parity-protected), and 256KB L2 cache with ECC - enabling deterministic real-time execution in Linux-based industrial edge nodes. It integrates PowerVR SGX530 graphics for 20M polygons/sec rendering and supports IEEE 1588v1 PTP for sub-microsecond time synchronization across distributed control systems.
Its PRU-ICSS subsystem contains two independent 200-MHz 32-bit RISC processors with 8KB instruction RAM, 8KB data RAM, and 12KB shared RAM (all parity-protected), directly interfacing to MII/RMII/RGMII Ethernet PHYs and enabling protocol stack offload for EtherCAT, PROFINET, and EtherNet/IP without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM-based industrial processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM3354BZCZA100 | Same 600-MHz Cortex-A8 core and PRU-ICSS, but rated for –40°C to +90°C (vs. +105°C for AM3352BZCZA100); no SGX530 graphics. | Suitable for indoor industrial environments where extended temperature range is not required and graphics acceleration is unnecessary. | Select AM3354BZCZA100 when thermal derating allows operation below 90°C and GUI rendering is handled externally or omitted. |
| AM3358BZCZA100 | 1-GHz Cortex-A8 core, same PRU-ICSS and peripherals, but rated for –40°C to +90°C; includes SGX530 graphics. | Required for high-throughput applications like video analytics preprocessing or complex multi-window HMI with OpenGL ES 2.0 rendering. | Choose AM3358BZCZA100 only if sustained >600-MHz CPU load justifies higher power consumption and thermal management overhead. |
Compared with AM3354BZCZA100, AM3352BZCZA100 adds extended temperature support (+105°C) and integrated graphics; versus AM3358BZCZA100, it trades peak frequency for thermal headroom and lower system cooling cost in sealed enclosures.

FAQ
What is the maximum operating frequency of the AM3352BZCZA100?
The AM3352BZCZA100 operates at a guaranteed maximum frequency of 600 MHz across its full industrial temperature range (–40°C to +105°C). This frequency is silicon-validated per TI SPRS717L revision L and supported by Dynamic Voltage Frequency Scaling (DVFS) to optimize power under varying computational loads. The AM3352BZCZA100 does not support 800-MHz or 1-GHz operation - those speeds are reserved for AM3357/AM3358 variants.
Does the AM3352BZCZA100 include an integrated graphics accelerator?
No, the AM3352BZCZA100 does not include the PowerVR SGX530 3D graphics engine. Graphics capability is absent in the AM3352 variant per TI's device feature comparison table (SPRS717L Table 3-1). For applications requiring OpenGL ES 1.1/2.0 or Direct3D Mobile support, AM3354BZCZA100 or AM3358BZCZA100 must be selected instead. The AM3352BZCZA100 retains full LCD controller functionality for 24-bit RGB output.
Which Ethernet protocols are hardware-accelerated by the AM3352BZCZA100's PRU-ICSS?
The AM3352BZCZA100's PRU-ICSS natively supports EtherCAT, PROFINET, EtherNet/IP, PROFIBUS, and Ethernet Powerlink through dedicated firmware and register-level peripheral access. These protocols execute entirely within the dual 200-MHz PRU RISC cores, bypassing the ARM Cortex-A8 and enabling deterministic sub-1-µs cycle times. IEEE 1588v1 timestamping is implemented in hardware for all Ethernet MACs, independent of PRU usage.
What memory types does the AM3352BZCZA100 support via its EMIF?
The AM3352BZCZA100 supports mDDR (LPDDR), DDR2, DDR3, and DDR3L via its 16-bit External Memory Interface (EMIF), with clock rates up to 400 MHz (800-MHz data rate for DDR3/DDR3L). It also supports NAND, NOR, and SRAM through the General-Purpose Memory Controller (GPMC), including BCH 4-/8-/16-bit ECC for NAND reliability. Total addressable space is 1 GB across both interfaces.
Is secure boot enabled by default on the AM3352BZCZA100?
Secure boot is optional on the AM3352BZCZA100 and requires custom part engagement with Texas Instruments during manufacturing - it is not factory-enabled. When activated, it leverages on-chip AES-256, SHA-256, and RNG accelerators to verify cryptographic signatures of boot images stored in external flash. Without TI's secure provisioning, the AM3352BZCZA100 boots unsigned code from internal ROM or configured external media.
