AM3354BZCZ80 概述
What is a Sitara microprocessor? A Sitara microprocessor (MPU) is a high-integration 32-bit ARM Cortex-A system-on-chip designed by Texas Instruments for industrial, automotive infotainment, and human-machine interface (HMI) applications. Unlike microcontrollers (MCUs) that run firmware from internal flash, MPUs require external DDR memory and execute a rich operating system such as Linux. The Sitara family sits in the hierarchy MPU -> microprocessor -> processor -> integrated circuit, and bridges the gap between low-power MCUs and high-end application processors.
Key features of the AM3354BZCZ80 include SGX530 3D graphics engine supporting OpenGL ES 2.0, two programmable real-time units (PRU-ICSS) for deterministic industrial protocols, dual 10/100/1000 Ethernet MACs, two USB 2.0 high-speed PHYs (host + device/host), six UARTs, two CAN controllers, three I2C ports, three SPI ports, and a 12-bit ADC. The integrated LCD controller supports up to 2048x2048 resolution, and the device is qualified for the 0 to 90 C commercial operating range as indicated by the absence of an industrial-grade temperature letter in the part number (the A100 variant covers -40 to 105 C industrial).
The architecture combines a single Cortex-A8 core running Linux/WinCE/Android, the SGX530 GPU for graphics, and two 32-bit PRU cores that operate independently of the ARM core for real-time deterministic I/O - critical for industrial protocols such as EtherCAT, Profibus, and Sercos. External 16-bit DDR2/DDR3 memory interface supports up to 1 GB of RAM.
Typical applications include industrial programmable logic controllers (PLC), human-machine interfaces (HMI), point-of-sale terminals, barcode scanners, smart grid concentrators, portable data terminals, and automotive infotainment head units. The integrated CAN and dual PRU make it especially attractive for industrial fieldbus gateways.
When designing with this MPU, ensure the PCB uses a 4-layer stackup with a continuous ground plane beneath the NFBGA, a matched-length DDR2/DDR3 interface, and proper power-rail sequencing. The BGA requires X-ray inspection and reflow with peak temperature not exceeding 260 C per JEDEC J-STD-020.

典型应用
AM3354BZCZ80 适用于 6 应用s: Industrial Human-Machine Interface (HMI), Programmable Logic Controller (PLC) and Industrial Gateway, Point-of-Sale (POS) Terminal, Portable Data Terminal and Barcode Scanner, Smart Grid Energy Concentrator, Automotive Infotainment Head Unit (Entry-Level).
Industrial Human-Machine Interface (HMI)
The AM3354BZCZ80 is purpose-built for industrial HMI panels where the integrated SGX530 3D graphics engine renders OpenGL ES 2.0 user interfaces on TFT LCDs up to 2048x2048. The 800 MHz Cortex-A8 with NEON SIMD delivers responsive touch-panel latency, while the dual PRU-ICSS cores handle deterministic button/keypad scanning in parallel with the ARM core running Linux/Qt or Crank Storyboard. The two integrated CAN 2.0B controllers allow direct connection to industrial fieldbus networks without external glue logic, and the 12-bit ADC reads analog backlight, temperature, and supply monitoring. Power dissipation at 800 MHz with typical 1.0 V core voltage remains manageable without active cooling for 7-inch panels.
推荐
Programmable Logic Controller (PLC) and Industrial Gateway
For PLC and industrial gateway designs, the AM3354BZCZ80's two PRU-ICSS cores provide the deterministic real-time I/O required by EtherCAT, Profinet, Sercos, and Powerlink slave protocols - offloading the ARM core so Linux handles only non-time-critical networking and configuration tasks. Dual gigabit Ethernet MACs allow line and ring topologies in redundant industrial networks. With 1 GB of addressable external DDR3 and TI's Processor SDK offering 10+ year LTS Linux support, the platform is suitable for long-life factory automation products. The two CAN controllers integrate fieldbus I/O for legacy equipment, while USB 2.0 high-speed supports local programming and HMI pendants.
推荐
Point-of-Sale (POS) Terminal
The AM3354BZCZ80 is a strong fit for retail POS terminals that require a graphical touchscreen UI, cryptographic acceleration for payment processing, and multiple peripheral interfaces. The SGX530 graphics engine accelerates Qt or web-based POS UIs with smooth animations, while the integrated LCD controller drives 7-15 inch capacitive touchscreens at WXGA resolution. Six UARTs handle barcode scanners, scales, cash drawers, and customer displays; three I2C buses connect to NFC readers and secure elements; and the USB 2.0 high-speed ports interface with magnetic-stripe readers and printers. Linux and Android BSPs from TI reduce time-to-market for retail OEMs.
推荐
Portable Data Terminal and Barcode Scanner
Handheld barcode scanners and portable data terminals leverage the AM3354BZCZ80's balance of compute performance, peripheral integration, and the SGX530 GPU for on-screen preview graphics. The six UARTs support legacy scanner engines (Honeywell, Zebra) and RFID reader modules simultaneously, while USB On-The-Go enables peripheral charging and data transfer. The 12-bit ADC reads battery voltage, current sensing, and temperature for accurate fuel-gauging, and the Cortex-A8 NEON engine accelerates JPEG decoding for camera-based barcode scanning. Industrial temperature grade variants (-40 to 105 C) suit cold-storage and outdoor logistics environments.
推荐
Smart Grid Energy Concentrator
The AM3354BZCZ80 is widely deployed in smart grid concentrators that aggregate metering data from hundreds of PLC nodes over low-voltage power-line communication. The dual PRU-ICSS cores implement real-time PLC MAC and PHY layers (PRIME, G3-PLC, IEEE 1901.2) with deterministic cycle times, while the ARM Cortex-A8 runs Linux for IPv6/6LoWPAN routing, DLMS/COSEM protocol stack, and secure TLS communication with utility head-end systems. Two CAN 2.0B controllers interface with substation IEDs, and the integrated gigabit Ethernet provides backhaul to the utility WAN. The extended temperature variants enable outdoor cabinet deployment.
推荐
Automotive Infotainment Head Unit (Entry-Level)
For entry-level automotive infotainment and cluster displays, the AM3354BZCZ80 (commercial grade) or its industrial-grade AM3354BZCZA100 sibling serve as the application processor driving 7-inch WVGA touchscreens, Bluetooth hands-free, and AM/FM radio control. The SGX530 handles 2D/3D navigation map rendering with OpenGL ES 2.0, and the dual CAN controllers interface with body and powertrain networks. Two USB 2.0 high-speed ports support Apple CarPlay and Android Auto connectivity via appropriate protocol stacks. Note: for production automotive designs, the AEC-Q100-qualified AM335x variants and modern Sitara AM62x are preferred.

关键差异点
- Integrated SGX530 3D GPU vs no-GPU alternatives （对比 AM3352BZCZ80)

- Commercial 0 to 90 C with 800 MHz headroom （对比 AM3354BZCZA100)
设计说明
Estimated: At 800 MHz with 1.0 V core and typical active current of 500 mA per the AM335x datasheet, the AM3354BZCZ80 dissipates roughly 0.5 W from the core rail. The 324-NFBGA ZCZ package has a theta_JA of approximately 19 C/W on a 4-layer JEDEC JESD51-7 test board, giving a junction-to-ambient rise of about 10 C. For forced-air enclosures above 60 C ambient, place thermal vias under the BGA and ensure at least 4 inner ground/power planes to spread heat. Active cooling is rarely required for commercial-grade designs.
Use a 6-layer PCB stackup for the AM3354BZCZ80 with continuous ground planes beneath the BGA to provide reference for the DDR3 interface and to shield high-speed signals. Per TI SPRS717, the DDR3 traces must be length-matched within 25 mils (0.635 mm) on the same routing layer with 50 ohm single-ended and 100 ohm differential impedance. BGA escape routing requires microvias or via-in-pad with 0.8 mm pitch; standard 0.4 mm vias are not feasible. Apply JEDEC J-STD-020 reflow profile with peak 245 C for lead-free assembly.
Do not connect the AM3354BZCZ80 PRU-ICSS pins directly to 24 V industrial signals without external level shifters and isolators - the PRU GPIOs are 3.3 V tolerant only. Do not omit the external 32.768 kHz crystal on the RTC_XTAL pins; the RTC clock domain is required for wake-from-hibernate power management. Finally, the DDR3 reference voltage (VREF) must be generated by a low-noise LDO like the TPS51200, not derived from a resistor divider, to avoid jitter-induced memory errors.
合规信息
RoHS and REACH compliant per TI product page. Commercial-grade (0 to 90 C); not AEC-Q100 qualified. Lead-free reflow per JEDEC J-STD-020. Choose AM3354BZCZA100 for AEC-Q100 / industrial -40 to 105 C deployments.
