AM1705CPTPA3

The AM1705CPTPA3 is an industrial-grade Sitara™ microprocessor based on a single ARM926EJ-S core running at 375 MHz. It integrates a 32-bit core with on-chip system control (CP15), SDRAM controller and common embedded interfaces to address industrial and embedded applications requiring robust connectivity and display support.

Designed for surface-mount deployment in a 176-HLQFP (24×24) exposed-pad package, this device targets embedded systems that need a compact, temperature-tolerant processor with integrated Ethernet, USB and display interfacing.

Key Features

• Core ARM926EJ-S single-core, 32-bit architecture running at 375 MHz for deterministic embedded processing.
• System Control On-chip system control coprocessor (CP15) to support core management and system configuration.
• Memory and Display Integrated SDRAM controller and LCD display interface controller for common embedded memory and HMI requirements.
• Connectivity 10/100 Mbps Ethernet (1) and USB 2.0 with integrated PHY (1) provide wired networking and host/device USB capability.
• Peripheral Interfaces I2C and other standard peripheral interfaces for sensor and peripheral integration.
• Package and Mounting 176-HLQFP (24×24) / 176-LQFP exposed pad package, surface-mount for compact PCB integration and thermal management.
• Industrial Temperature Range Rated for operation from -40°C to 105°C to meet demanding environmental conditions.
• Regulatory Status RoHS compliant.

Typical Applications

• Industrial Controls Use as the processing element in control systems where Ethernet connectivity and industrial temperature operation are required.
• Human–Machine Interfaces (HMI) Drive LCD panels and handle local user-interface processing with the integrated display controller and SDRAM support.
• Networked Embedded Devices Provide 10/100 Mbps Ethernet and USB 2.0 connectivity for network-attached embedded products.
• Embedded Communication Gateways Serve as a compact processor for protocol bridging and peripheral aggregation using I2C, USB and Ethernet interfaces.

Unique Advantages

• Compact, surface-mount package: 176-HLQFP (24×24) with exposed pad supports compact board layouts and improved thermal dissipation.
• Industrial temperature tolerance: Rated from -40°C to 105°C for reliable operation in harsh environments.
• Integrated wired connectivity: Built-in 10/100 Mbps Ethernet and USB 2.0 with PHY reduce external component count and simplify designs.
