AM3357BZCZD60 概述
A microprocessor (MPU) is an integrated processing device that integrates a CPU core, memory controller, peripheral controllers and I/O into a single chip, distinguishing it from a microcontroller (MCU) which typically emphasizes on-chip Flash and simpler peripherals. Within the system hierarchy, an MPU sits above basic MCUs and below application processors in computational capability, providing the horsepower to run high-level operating systems such as Linux while maintaining the deterministic I/O needed for industrial control. The Sitara family specifically targets applications requiring a balance of high-level OS support and real-time industrial protocols on a single die.
Key features include the Cortex-A8 core with NEON SIMD and VFPv3 floating-point hardware, 32KB L1 instruction and data caches, a 256KB L2 cache, a 32-bit LPDDR1/DDR2/DDR3/mDDR memory controller, two 12-bit ADCs, two USB 2.0 high-speed ports (with one capable of PHY interface), two industrial-grade CAN controllers, two PRU subsystems for deterministic I/O, a real-time clock, an SGX530 3D graphics accelerator, and a LCD controller with WXGA resolution support. The integrated EtherCAT slave controller and PROFIBUS support eliminate the need for an external ASIC, reducing BOM cost for industrial automation designs.
The architecture is built on TI's 65nm CMOS process, supports ARMv7-A instruction set, and provides boot sources including SPI, MMC/SD, UART and NAND/NOR Flash. Power management is handled through multiple core voltage domains enabling dynamic frequency scaling and deep sleep modes with RTC retention. A typical 1.1V core supply and 3.3V I/O supply are required, with the integrated LDOs and PMIC companion devices managing the sequencing. Security features include a hardware crypto accelerator (AES, SHA, RNG) and secure boot support through the AM335x ROM bootloader.
Typical applications include industrial programmable logic controllers (PLC), human-machine interfaces (HMI), point-of-sale (POS) terminals, industrial gateways, motor control drives with EtherCAT, machine vision systems, portable medical devices, and networked sensors with fieldbus connectivity. The dual-PRU subsystem is especially useful for custom industrial I/O protocols requiring sub-microsecond deterministic response without burdening the Cortex-A8 core.
When designing with this device, pay close attention to the DDR3 memory trace impedance and length matching - the DDR3 interface requires careful signal integrity work. The PRU firmware should be developed using TI's PRU-RemoteProc and CCS toolchain. For EtherCAT or PROFIBUS applications, use TI's certified protocol stacks rather than reimplementing from scratch. Refer to TI's AM335x Hardware User Guide and the PRU-ICSS Reference Guide for detailed peripheral programming examples and reference schematics.

Industrial EtherCAT Slave Controller
The AM3357BZCZD60 is purpose-built for EtherCAT slave applications, with the integrated EtherCAT slave controller and dual PRU-ICSS providing deterministic sub-microsecond fieldbus response without external ASICs. The 600 MHz Cortex-A8 core runs the application stack while the PRU cores handle the EtherCAT state machine and Distributed Clocks (DC) synchronization at 200 MHz. Placed on the slave station board with a standard industrial 24V-to-5V buck and TI's TPS65217 PMIC for power sequencing, the AM3357 eliminates the need for a dedicated EtherCAT slave controller chip, reducing BOM cost by $3-$8 per node. The two CAN 2.0B controllers add gateway functionality between EtherCAT and CANopen networks.
推荐
Human-Machine Interface (HMI) Panels
The AM3357BZCZD60 supports a WXGA-capable LCD controller and the SGX530 graphics accelerator, enabling high-resolution HMI panels with smooth animation at 600 MHz Cortex-A8 throughput. The two 12-bit ADCs handle resistive touch screen digitisation directly without an external controller, while the two USB 2.0 ports support external peripherals like barcode scanners and keyboards. Typical use places the AM3357BZCZD60 on a panel mainboard running Linux with Qt or a web-based HMI framework, driving a 7-10 inch TFT display at 1280x800. The industrial -40C to +90C temperature range supports outdoor and factory floor deployment.
推荐
Programmable Logic Controllers (PLC)
The AM3357BZCZD60 brings Linux programmability and deterministic EtherCAT/PROFIBUS support to mid-range PLCs, replacing the traditional combination of a microcontroller + external ASIC. The 600 MHz Cortex-A8 runs a soft PLC runtime like CODESYS or OpenPLC, while the dual PRU-ICSS handle EtherCAT slave communication with deterministic 25 microsecond cycle times. Two 12-bit ADCs at 200 kS/s handle analog sensor inputs (4-20 mA, 0-10 V via signal conditioning), and the two CAN ports connect to distributed I/O slices. The DDR3 interface and Cortex-A8 performance enable ladder-logic execution and high-level language integration in a single chip.

Typical applications include legacy-to-Ethernet migration gateways, OPC UA aggregator nodes, and cloud-edge gateways in Industry 4.0 deployments. The hardware AES/SHA accelerator secures cloud-bound data without burdening the main CPU.
推荐
Motor Control and Servo Drive
The AM3357BZCZD60 is a strong fit for industrial servo drives, where the 600 MHz Cortex-A8 runs the high-level motion controller while the dual PRU-ICSS handles the EtherCAT slave communication and the field-oriented control (FOC) loops at deterministic rates. The two 12-bit ADCs at 200 kS/s sample motor phase currents, while PWM outputs drive the power stage through TI's TPS gate drivers. The integrated LCD controller supports a local status display, eliminating a secondary microcontroller. The -40C to +90C industrial temperature range suits drive cabinet installations with minimal airflow.
推荐
Portable Medical Device Interface

设计说明
The 324-ball NFBGA ZCZ package at 0.8 mm ball pitch requires a minimum 6-layer PCB stackup with laser-drilled microvias. Use ENIG surface finish for the BGA pads and route all DDR3 signals on the top layer under the BGA escape region only. Refer to TI's AM335x Hardware User Guide Section 8 (Board Design) for the approved stackup and escape routing pattern.
Estimated: the DDR3 interface to the AM3357BZCZD60 must maintain trace impedance of 50 ohms single-ended and 100 ohms differential, with length matching within 5 mils for byte lanes. Use fly-by topology for multi-rank configurations. Place the DDR3 VTT termination resistors no more than 500 mils from the DRAM chips and AM3357BZCZD60 balls.
At 1.1 V VDD_CORE with a 600 MHz Cortex-A8 + dual PRU-ICSS active load, the AM3357BZCZD60 dissipates approximately 1.5-2.0 W. The 15x15 mm NFBGA package relies on PCB thermal vias and copper pours for dissipation; the Hardware User Guide specifies a 4x4 micro-via array under the central thermal balls. Mounting on a 4-layer board without thermal management results in junction temperatures above 105C under sustained load.
Boot configuration pins (SYSBOOT[15:0]) must be set via 10K pull-up/pull-down resistors BEFORE first power-up; misconfiguration results in bricked devices. Do not omit the 32.768 kHz external crystal for the RTC - the internal oscillator is not accurate enough for Ethernet PTP timestamps. The PMIC handshake via I2C must complete within 1 second of VDD_CORE rising or the AM3357BZCZD60 enters a reset loop.
