Texas Instruments AM3358BZCZA80

Overview

AM3358BZCZA80 from Texas Instruments is a 1-GHz ARM Cortex-A8-based Sitara™ processor with integrated PowerVR SGX530 3D graphics engine, dual 1-Gbps Ethernet MACs with switch, PRU-ICSS for industrial protocols (EtherCAT, PROFINET), and 8-channel 12-bit SAR ADC. It supports DDR3/DDR3L at 800-MHz data rate and operates in 0°C to 90°C ambient temperature.

For engineers reviewing the AM3358BZCZA80 datasheet, AM3358BZCZA80 pinout, AM3358BZCZA80 application, or AM3358BZCZA80 equivalent, this page delivers verified technical context, package mapping, real-time subsystem capabilities, memory interface timing constraints, and validated alternative options for industrial embedded design.

Technical Context

The AM3358BZCZA80 implements a single-core ARM Cortex-A8 CPU with NEON SIMD coprocessor, 32KB L1 instruction + 32KB L1 data cache (parity-protected), and 256KB L2 cache (ECC-protected). Its PRU-ICSS contains two independent 200-MHz programmable real-time units with 8KB instruction RAM, 8KB data RAM, and 12KB shared RAM - each supporting EtherCAT frame processing and industrial I/O timing control.

Memory subsystem includes a 16-bit EMIF supporting DDR3/DDR3L up to 400-MHz clock (800-MHz data rate), GPMC with NAND/NOR/SRAM support and BCH-based ECC (4/8/16-bit per 512-byte block), and OCMC RAM with retention mode for fast wakeup. Clocking uses five ADPLLs to generate MPU, DDR, USB, and peripheral clocks from an internal 15–35-MHz oscillator.

Key Specifications

Pinout & Package

The AM3358BZCZA80 is housed in a 324-ball NFBGA (ZCZ package) with 0.80-mm ball pitch and 15.0 mm × 15.0 mm body size. Ball assignment follows TI's ZCZ pin map; key functional groups include DDR3 interface (A0–A15, D0–D15, DQS0/1, CKE, CSn, ODT), dual MII/RMII/RGMII Ethernet ports, PRU-ICSS I/O banks, and dedicated ADC/TSC analog inputs (AIN0–AIN7).

FAQ

What is the maximum DDR3 data rate supported by AM3358BZCZA80?

The AM3358BZCZA80 supports DDR3 and DDR3L memory at a 400-MHz clock frequency, delivering an 800-MHz data rate (double-data-rate) across its 16-bit EMIF. This enables up to 640 MB/s peak bandwidth for Linux kernel execution and application memory access, validated per TI's SPRS717L datasheet Section 7.7.

Does AM3358BZCZA80 include hardware cryptographic acceleration?

Yes, AM3358BZCZA80 integrates dedicated crypto hardware accelerators for AES-128/192/256, SHA-1/256, and random number generation (RNG). These modules operate independently of the ARM Cortex-A8 core and are accessible via TI's Crypto Library - enabling secure boot and TLS offload without CPU overhead.

Can AM3358BZCZA80 run real-time Ethernet protocols like EtherCAT?

Yes, AM3358BZCZA80 supports EtherCAT natively through its PRU-ICSS subsystem. The dual 200-MHz programmable real-time units handle frame processing, synchronization, and I/O mapping with deterministic latency under 100 µs - confirmed in TI's AM335x PRU-ICSS documentation and industrial reference designs.

What is the operating temperature range for AM3358BZCZA80?

The AM3358BZCZA80 is specified for operation from 0°C to 90°C ambient temperature. This commercial-grade rating applies to the BZCZA80 variant specifically - distinct from industrial variants like AM3359BZCZD80 (–40°C to 105°C) or AM3357BZCZD80 (–40°C to 90°C), as documented in Table 3-1 of SPRS717L.

How many Ethernet ports does AM3358BZCZA80 support, and what interfaces are available?

AM3358BZCZA80 integrates two Gigabit Ethernet MACs with an on-chip switch fabric. Each MAC supports MII, RMII, and RGMII physical layer interfaces, and both implement IEEE 1588v1 hardware timestamping. The device does not include integrated PHYs - external PHYs (e.g., DP83848) must be used per TI's AM335x hardware design guidelines.
