AM1705BPTPA3

The AM1705BPTPA3 is an industrial-grade Sitara™ microprocessor from Texas Instruments based on a single ARM926EJ-S core running at 375 MHz. Designed for embedded applications, it combines core processing performance with integrated interfaces for connectivity and display.

With on-chip support for SDRAM, an LCD controller, 10/100 Mbps Ethernet, USB 2.0 with PHY, and I2C, this device targets embedded systems that require a compact, surface-mount MPU in a 176-pin HLQFP package for reliable operation across a wide temperature range.

Key Features

• Core: ARM926EJ-S single core, 32-bit architecture operating at 375 MHz for deterministic embedded processing.
• Memory Controller: Integrated SDRAM controller to support external SDRAM memory configurations.
• Connectivity: Integrated 10/100 Mbps Ethernet controller and USB 2.0 with PHY for networked and USB-enabled devices.
• Display Interface: LCD controller for direct connection to display panels and HMI designs.
• Peripheral Interfaces: I2C interface for sensor and peripheral communication; System Control and CP15 listed as system coprocessor resources.
• Package and Mounting: 176-HLQFP (24×24) surface-mount package with exposed pad (176-LQFP exposed pad variant noted) for thermal and board-level integration.
• Industrial Grade: Rated for industrial applications with an operating temperature range of −40°C to 105°C.

Typical Applications

• Industrial Control: Use in embedded controllers and PLC-adjacent devices that benefit from industrial temperature operation and network connectivity.
• Human-Machine Interfaces (HMI): Drive LCD-based operator panels where the integrated LCD controller and SDRAM support user displays.
• Networked Embedded Devices: Embedded gateways, controllers, or appliances requiring 10/100 Ethernet and USB connectivity.
• Instrumentation and Monitoring: Sensor aggregation and instrument front-ends that require I2C interfacing and reliable operation in industrial environments.

Unique Advantages

• Integrated Connectivity: On-chip 10/100 Ethernet and USB 2.0 + PHY reduce external component count for networked designs.
• Compact Surface-Mount Package: 176-HLQFP (24×24) with exposed pad enables dense PCB layouts and thermal management.
• Industrial Temperature Range: −40°C to 105°C rating supports deployment in demanding environmental conditions.
• Display-Ready: Built-in LCD controller simplifies HMI implementation without separate display bridge chips.
• Flexible Memory Support: SDRAM controller allows designers to choose external memory configurations to match application needs.
• Proven Architecture: ARM926EJ-S core delivers established 32-bit processing suitable for embedded control and interface tasks.
