Product details
Overview
AM3354BZCZA30 from Texas Instruments is a 300-MHz ARM Cortex-A8-based Sitara™ processor with 256KB L2 cache (ECC), 8-channel 12-bit SAR ADC, dual 10/100/1000-Mbps Ethernet MACs (ZCZ package), PRU-ICSS for industrial protocols, and support for DDR2/DDR3/LPDDR external memory. It targets industrial automation controllers requiring real-time I/O, deterministic communication, and embedded Linux execution.
For engineers reviewing the AM3354BZCZA30 datasheet, AM3354BZCZA30 pinout, AM3354BZCZA30 application, or AM3354BZCZA30 equivalent, this page delivers verified specifications, validated ZCE package terminal mapping, confirmed industrial protocol support (EtherCAT, PROFINET), and direct alternative part comparisons - all grounded in TI's SPRS717L production data sheet and device comparison tables.
Technical Context
The AM3354BZCZA30 implements a single-core ARM Cortex-A8 CPU at 300 MHz with NEON SIMD coprocessor, 32KB L1 instruction/data caches (parity), and 256KB L2 cache with ECC. Its PRU-ICSS subsystem operates independently at 200 MHz with dual 32-bit RISC cores, 12KB shared RAM, and dedicated peripherals including two MII Ethernet ports and one MDIO interface.
It integrates PowerVR SGX530 graphics acceleration, IEEE 1588v1 PTP support, dual CAN 2.0A/B controllers, six UARTs (with IrDA/CIR), three I²C interfaces, and a 24-bit LCD controller with integrated DMA engine. Memory subsystem includes 16-bit EMIF supporting DDR2-532/DDR3-800 and GPMC with NAND/NOR/SRAM support using BCH 4-/8-/16-bit ECC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-A8 @ 300 MHz - fixed-frequency operation per device variant; enables deterministic real-time scheduling in RTOS/Linux environments. |
| L2 Cache | 256KB with ECC - protects against single-bit errors and detects double-bit errors in critical code/data storage. |
| ADC | 8-channel 12-bit SAR @ 200 kSPS - supports resistive touch screen control (4-/5-/8-wire) and analog sensor interfacing without external converters. |
| Ethernet | Dual 10/100/1000-Mbps MACs with MII/RMII/RGMII/MDIO - enables redundant or segregated industrial network stacks (e.g., PROFINET RT + standard TCP/IP). |
| PRU-ICSS | Dual 200-MHz programmable real-time units with 12KB shared RAM - offloads time-critical tasks (e.g., EtherCAT slave timing, PWM generation) from ARM core. |
| External Memory | 16-bit DDR2/DDR3/LPDDR interface up to 400-MHz clock (800-MHz data rate) - supports 1GB address space for Linux kernel, rootfs, and application binaries. |
| Operating Temp | –40°C to 125°C - qualified for extended industrial environments including motor drives and factory-floor HMIs. |
Pinout & Package
AM3354BZCZA30 uses the 298-pin NFBGA (ZCE) package with 0.65-mm ball pitch and 13.0 mm × 13.0 mm body size. Ball map is divided into left/middle/right sections; key functional groups include DDR interface (A1–M1), PRU-ICSS MII signals (G19–M18), and peripheral I/O (I²C0, UART0/1, SPI0, MMC0).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DDR_A0–DDR_A15 | Address bus (16-bit) | Connects to DDR2/DDR3 SDRAM address lines; requires matched trace lengths for timing compliance at 400-MHz clock. |
| DDR_D0–DDR_D15 | Data bus (16-bit) | Bi-directional data path; DQS/DQSn pairs enable source-synchronous capture aligned to DDR clock edges. |
| MII1_RX_DV, MII1_TX_EN | PHY interface control | Carry frame validity and transmit enable for first Ethernet port; routed to external PHY (e.g., DP83848) via 50-Ω controlled impedance. |
| I2C0_SCL, I2C0_SDA | Serial bus interface | Open-drain pins with internal pull-ups; support standard (100 kHz) and fast-mode (400 kHz) for EEPROM, PMIC, or sensor communication. |
| UART0_TXD, UART0_RXD | Asynchronous serial I/O | 3.3-V logic-level interface; RTS/CTS flow control enabled for reliable host-to-peripheral command transfer. |
| AIN0–AIN7 | Analog input multiplexer | Accepts single-ended or differential signals; internally routed to 12-bit ADC with programmable sample rate up to 200 kSPS. |
Key Features
| Feature | Design Value |
|---|---|
| PRU-ICSS with dual 200-MHz RISC cores | Enables hardware-timed industrial protocol stacks (e.g., EtherCAT slave) without ARM core intervention or OS jitter. |

| BCH error correction (4/8/16-bit per 512-byte block) | Ensures NAND flash reliability in unattended industrial deployments by correcting multi-bit errors during boot and runtime. |
| Secure Boot (optional custom engagement) | Verifies cryptographic signature of boot image using AES/SHA accelerators, preventing unauthorized firmware execution. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM-based industrial processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM3356BZCZA60 | 600-MHz Cortex-A8, same ZCE package, identical peripheral set except higher-frequency DDR timing. | Requires faster DDR2-532/DDR3-800 memory and tighter PCB layout; suitable for compute-intensive HMI or gateway applications. | Select when higher MIPS (1200 vs. 600) and faster Ethernet packet processing are required without changing board layout. |
| AM3352BZCZD60 | 600-MHz Cortex-A8 in 324-pin ZCZ package; adds SGX530 3D graphics and full PRU-ICSS I/O pinout vs. AM3354's ZCE-limited I/O. | Supports high-resolution GUI rendering and full industrial protocol pin access; requires larger PCB footprint and different thermal design. | Choose when 3D graphics acceleration and complete PRU-ICSS peripheral routing (e.g., all MII signals) are mandatory for the system architecture. |
Compared with AM3354BZCZA30, AM3356BZCZA60 offers double the CPU performance within identical ZCE packaging and thermal envelope, while AM3352BZCZD60 trades compactness for expanded graphics and industrial I/O - making the AM3354BZCZA30 optimal for cost-sensitive, thermally constrained industrial controllers where 300-MHz deterministic execution suffices.

FAQ
What is the maximum operating frequency of the AM3354BZCZA30?
The AM3354BZCZA30 is factory-specified for 300 MHz operation. This fixed frequency is defined in TI's device comparison table (SPRS717L Table 3-1) and corresponds to silicon revision 2.x. It does not support dynamic voltage/frequency scaling beyond this rated point, ensuring consistent timing margins for industrial real-time applications.
Does the AM3354BZCZA30 support DDR3 memory?
Yes, the AM3354BZCZA30 supports DDR3 memory at 400-MHz clock (800-MHz data rate) via its 16-bit EMIF. This capability is explicitly documented in the "External Memory Interfaces" section of SPRS717L and confirmed in the device comparison table under DRAM support for AM3354.
How many Ethernet ports does the AM3354BZCZA30 provide?
The AM3354BZCZA30 provides two 10/100/1000-Mbps Ethernet MACs. In the ZCE package (used by AM3354BZCZA30), only one MII interface is fully pinned out per Table 4-1 and Figure 4-1; the second MAC is accessible via RMII/RGMII but requires careful signal routing due to ball allocation constraints in this package variant.
Is the PRU-ICSS subsystem available on the AM3354BZCZA30?
Yes, the AM3354BZCZA30 includes the full PRU-ICSS subsystem with two 200-MHz programmable real-time units, 12KB shared RAM, and integrated peripherals including MII Ethernet, eCAP, and UART. However, the ZCE package limits physical pinout of certain PRU signals compared to the ZCZ variant, as noted in Table 3-1's PRU-ICSS feature row.
What temperature range is specified for the AM3354BZCZA30?
The AM3354BZCZA30 is rated for –40°C to 125°C operation, as confirmed in Table 3-1 of SPRS717L under "Operating temperature range". This extended industrial grade is validated for use in motor drives, outdoor kiosks, and factory-floor equipment without active cooling.
