Product details
Overview
AM3352BZCZA80 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, programmable logic controllers, and connected vending systems.
For engineers reviewing the AM3352BZCZA80 datasheet, AM3352BZCZA80 pinout, AM3352BZCZA80 application, or AM3352BZCZA80 equivalent, this page delivers verified technical context, validated pin functions, confirmed industrial protocol support, exact package mapping (NFBGA-324, 0.80-mm pitch), and real-world use-value metrics for embedded Linux and real-time control designs.
Technical Context
The AM3352BZCZA80 implements a single-core ARM Cortex-A8 CPU with NEON SIMD coprocessor, 32KB L1 instruction and 32KB L1 data cache (parity), and 256KB L2 cache with ECC - enabling deterministic execution for Linux-based industrial applications. Its PRU-ICSS subsystem operates independently at 200 MHz with dual 32-bit RISC cores, 8KB instruction RAM, 8KB data RAM, and 12KB shared RAM (all parity-protected), delivering hard real-time I/O handling without CPU intervention.
It integrates dual Gigabit Ethernet MACs with IEEE 1588v1 PTP support, two CAN 2.0B controllers, six UARTs (including full modem control on UART1), three MMC/SD interfaces, and a 24-bit LCD controller with DMA-driven raster engine - all interconnected via L3/L4 interconnect fabric and managed by a dedicated PRCM module supporting DVFS and SmartReflex Class 2B adaptive voltage scaling.

FAQ
What is the maximum operating frequency of the AM3352BZCZA80?
The AM3352BZCZA80 is rated for 600 MHz operation under industrial temperature conditions (–40°C to +105°C). This frequency is validated across process corners and voltage tolerances per TI's SPRS717L datasheet revision March 2020. The AM3352BZCZA80 achieves 1200 MIPS at this speed, enabling real-time Linux execution while maintaining thermal headroom for sustained industrial workloads.
Does the AM3352BZCZA80 support EtherCAT protocol natively?
Yes, the AM3352BZCZA80 supports EtherCAT through its integrated PRU-ICSS subsystem. The dual 200-MHz PRU cores execute EtherCAT frame processing independently of the ARM Cortex-A8, enabling sub-100-µs cycle times and jitter-free synchronization. TI provides certified EtherCAT slave stack and reference firmware specifically validated for AM3352BZCZA80 in ZCZ packaging.
What memory types does the AM3352BZCZA80 EMIF support?
The AM3352BZCZA80 supports mDDR (LPDDR), DDR2, DDR3, and DDR3L via its 16-bit external memory interface. It achieves 266-MHz clock (532-Mbps data rate) for DDR2 and 400-MHz clock (800-Mbps data rate) for DDR3/DDR3L. The interface supports one x16 or two x8 memory configurations and includes hardware BCH ECC for NAND flash boot reliability.
How many Ethernet ports does the AM3352BZCZA80 include?
The AM3352BZCZA80 includes two independent 10/100/1000-Mbps Ethernet MACs with integrated switch fabric. Both ports support MII, RMII, RGMII, and MDIO interfaces, and implement IEEE 1588v1 Precision Time Protocol for time-synchronized networking. In ZCZ packaging (which applies to AM3352BZCZA80), both MACs are fully pinned out and functional.
Is hardware cryptographic acceleration available on the AM3352BZCZA80?
Yes, the AM3352BZCZA80 integrates dedicated hardware accelerators for AES-128/192/256, SHA-1/256, and random number generation (RNG). These modules operate independently of the Cortex-A8 core and are accessible via TI's Cryptographic Services Library (CSL) - enabling TLS 1.2 handshakes in <10 ms and secure boot verification without impacting application performance.
