FAQ
What is the maximum operating frequency of the AM3352ZCZASUS processor core?
The AM3352ZCZASUS features an ARM Cortex-A8 core rated for 600 MHz operation under industrial temperature conditions (-40°C to +105°C). This frequency is validated per TI's SPRS717L datasheet and corresponds to 1200 MIPS performance. The AM3352ZCZASUS does not support 800-MHz or 1-GHz operation - those speeds are reserved for higher-tier variants like AM3357 and AM3358.
Does the AM3352ZCZASUS support IEEE 1588 Precision Time Protocol?
Yes, the AM3352ZCZASUS supports IEEE 1588v1 Precision Time Protocol in hardware through its dual Ethernet MACs. Each EMAC includes dedicated timestamp registers and hardware capture logic for sub-microsecond accuracy on packet ingress and egress - critical for time-synchronized industrial networks. IEEE 1588v2 is not supported on this variant.
What package type and ball count does the AM3352ZCZASUS use?
The AM3352ZCZASUS uses a 324-ball NFBGA package with ZCZ suffix, 0.80-mm ball pitch, and 15.0 mm × 15.0 mm body size. This is distinct from the 298-ball ZCE package used in lower-I/O variants. The ZCZ package exposes all Ethernet, PRU, and LCD interface signals required for full-feature industrial designs.
Can the AM3352ZCZASUS execute EtherCAT master functionality?
Yes, the AM3352ZCZASUS can implement EtherCAT master functionality using its PRU-ICSS subsystem. TI provides reference firmware and documentation confirming EtherCAT master support on AM3352ZCZASUS, leveraging the dual 200-MHz PRUs and dedicated MII Ethernet ports. Full implementation requires PRU firmware and external PHY configuration.
What is the ADC resolution and sampling rate of the AM3352ZCZASUS?
The AM3352ZCZASUS integrates an 8-channel, 12-bit successive approximation register (SAR) ADC with a maximum sampling rate of 200 kSPS. It supports configurable input multiplexing and operates as a 4-/5-/8-wire resistive touch screen controller - eliminating need for external TSC ICs in HMI designs.
