FAQ
What is the maximum operating frequency of the AM3357ZCZD27?
The AM3357ZCZD27 operates at a maximum guaranteed frequency of 800 MHz across its specified industrial temperature range (–40°C to 90°C). This frequency is validated per TI's Operating Performance Points (OPPs) and supported by the on-chip ADPLLs generating MPU subsystem clocks. The AM3357ZCZD27 does not support 1-GHz operation - that capability is reserved for the AM3358ZCZD27 and AM3359ZCZD27 variants.
Does the AM3357ZCZD27 include hardware acceleration for industrial Ethernet protocols?
Yes, the AM3357ZCZD27 includes a dedicated Programmable Real-Time Unit Subsystem and Industrial Communication Subsystem (PRU-ICSS) with dual MII Ethernet ports, MDIO, and programmable PRUs capable of running EtherCAT, PROFINET, and EtherNet/IP stacks independently of the ARM Cortex-A8 core. This hardware offload ensures sub-100-µs cycle times without CPU scheduling jitter.
What memory interfaces are supported by the AM3357ZCZD27?
The AM3357ZCZD27 supports a 16-bit DDR3/DDR3L interface (400-MHz clock, 800-MHz data rate), mDDR/LPDDR, DDR2, and a flexible General-Purpose Memory Controller (GPMC) for NAND/NOR/SRAM with 4-/8-/16-bit BCH ECC. It does not support LPDDR2 or DDR4. External memory capacity is limited to 1 GB addressable space across all interfaces.
Is the AM3357ZCZD27 pin-compatible with other AM335x ZCZ-package devices?
Yes, the AM3357ZCZD27 is fully pin-compatible with all ZCZ-package AM335x devices (AM3351ZCZ through AM3359ZCZ), sharing identical 324-ball NFBGA mechanical layout, ball pitch (0.80 mm), and signal assignment per TI SPRS717L Section 4.1.2. This enables direct substitution within the same PCB footprint for frequency or feature scaling.
What is the role of the PRU-ICSS in the AM3357ZCZD27?
The PRU-ICSS in the AM3357ZCZD27 consists of two independent 200-MHz 32-bit RISC processors (PRU0/PRU1), 12KB shared RAM, and dedicated peripherals including MII Ethernet ports, UART, eCAP, and eHRPWM modules. It executes real-time industrial protocols like EtherCAT without ARM core involvement, enabling deterministic I/O handling and precise PWM generation for motor control.
