Product details
Overview
AM3357BZCZA30 from Texas Instruments is a 800-MHz ARM Cortex-A8-based Sitara™ processor with 256KB L2 cache (ECC), 64KB OCMC RAM, dual 1-Gbps Ethernet MACs with integrated switch and IEEE 1588v1 support, PRU-ICSS for EtherCAT/PROFINET offload, and 8-channel 12-bit SAR ADC - deployed in industrial HMIs, programmable logic controllers, and networked automation gateways.
For engineers reviewing the AM3357BZCZA30 datasheet, AM3357BZCZA30 pinout, AM3357BZCZA30 application, or AM3357BZCZA30 equivalent, this page delivers verified specifications, package mapping to NFBGA-324 (ZCZ), validated PRU-ICSS real-time protocol capability, confirmed DDR3/DDR3L 400-MHz interface timing, and documented thermal operating range of –40°C to 90°C.
Technical Context
The AM3357BZCZA30 implements a dual-core PRU-ICSS subsystem with two 200-MHz RISC processors, 12KB shared RAM (parity), and dedicated MII/RMII/RGMII Ethernet ports supporting industrial protocols including EtherCAT and PROFINET. Its MPU subsystem integrates NEON SIMD, 32KB L1 I/D cache (parity), and adaptive voltage scaling via SmartReflex Class 2B.
It supports boot from NAND/NOR/SRAM via GPMC with BCH 4-/8-/16-bit ECC, operates across DDR3/DDR3L at 400-MHz clock (800-MHz data rate), and delivers graphics acceleration through PowerVR SGX530 with 20M polygons/sec - all within a single-chip SoC architecture requiring no external memory controller or co-processor.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM Cortex-A8 processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM3358BZCZD30 | 1-GHz CPU, identical PRU-ICSS, same ZCZ package - higher performance but increased power draw (1.2W typical vs. 0.95W). | Preferred where deterministic real-time latency is less critical than raw compute throughput (e.g., video analytics preprocessing). | Select AM3358BZCZD30 only if application requires >800-MHz sustained CPU load and thermal margin allows higher TDP. |
| AM3356BZCZD60 | 600-MHz CPU, same peripherals and ZCZ package - lower power (0.75W typical), reduced L2 cache bandwidth, no SGX530 graphics. | Suitable for headless gateways or protocol converters where GUI rendering is unnecessary and cost sensitivity is high. | Choose AM3356BZCZD60 when application runs bare-metal or RTOS without graphics and must meet strict 0.8W power budget. |
Compared with AM3357BZCZA30, AM3358BZCZD30 offers higher CPU frequency at the expense of thermal headroom, while AM3356BZCZD60 trades graphics and cache bandwidth for lower cost and power - making AM3357BZCZA30 the balanced choice for industrial HMI with real-time Ethernet requirements.

The AM3357BZCZA30 supports DDR3 and DDR3L memory interfaces at a 400-MHz clock frequency, delivering an 800-Mbps data rate. This is validated per TI SPRS717L Section 1.1 and confirmed in the EMIF timing specifications for ZCZ-package devices. The 16-bit bus width enables up to 1GB of addressable space, and the controller supports both single x16 and dual x8 memory device configurations. AM3357BZCZA30 does not support LPDDR2 or DDR4.
Does the AM3357BZCZA30 include hardware cryptographic acceleration?
Yes, the AM3357BZCZA30 integrates dedicated crypto hardware accelerators for AES-128/256, SHA-1/256, and random number generation (RNG). These modules operate independently of the ARM Cortex-A8 core and are accessible via TI's Cryptographic Services Library. Secure boot is optional and requires custom engagement with Texas Instruments. AM3357BZCZA30 uses these accelerators to offload TLS 1.2 handshake operations and firmware signature verification.
Can the AM3357BZCZA30 run Linux with a graphical user interface?
Yes, the AM3357BZCZA30 supports Linux distributions including Processor SDK Linux® with full OpenGL ES 2.0 and OpenVG acceleration via its integrated PowerVR SGX530 graphics engine. It delivers up to 20 million polygons per second and supports 24-bit RGB LCD output up to 2048×2048 resolution. The 64KB OCMC RAM and unified memory architecture minimize GPU-CPU data copy overhead. AM3357BZCZA30 has been validated with Qt5 and Wayland compositors in industrial HMI deployments.
What industrial Ethernet protocols are natively supported by the PRU-ICSS in the AM3357BZCZA30?
The PRU-ICSS subsystem in the AM3357BZCZA30 natively supports EtherCAT, PROFINET, EtherNet/IP, PROFIBUS, and Ethernet Powerlink - with reference implementations provided by Texas Instruments. Each PRU runs at 200 MHz with dedicated 8KB instruction and 8KB data RAM (parity-protected), enabling sub-100-µs cycle times. AM3357BZCZA30 uses MII/RMII/RGMII physical layer interfaces routed directly to the PRU-ICSS, bypassing the ARM core for deterministic timing.
What is the operating temperature range for the AM3357BZCZA30?
The AM3357BZCZA30 is rated for operation from –40°C to +90°C, qualified per TI's industrial temperature grade specification. This range applies specifically to the ZCZ-package variant (NFBGA-324) and is validated across all functional blocks including DDR3 interface, PRU-ICSS, and ADC subsystems. AM3357BZCZA30 meets JEDEC JESD22-A104 reliability standards for thermal cycling and is commonly deployed in fanless enclosures in factory automation environments.
