AM1705CPTPA3

Overview

The AM1705CPTPA3 is a microprocessor unit (MPU) belonging to the Sitara family, manufactured by Texas Instruments. It integrates an ARM926EJ-S core operating at a maximum clock frequency of 456 MHz within a 176-pin HLQFP package featuring a 24x24mm footprint and exposed pad. The device supports a 32-bit data bus width and includes an integrated SDRAM controller for program space management. It operates within a temperature range of 0°C to +90°C and utilizes System Control and CP15 co-processors.

Feature Summary

• Integrates an ARM926EJ-S processor core with System Control and CP15 co-processors for embedded computing tasks.
• Includes an on-chip SDRAM controller to manage external memory interfaces directly.
• Features integrated communication peripherals including Ethernet MAC, USB 2.0 with PHY, I2C, UART, SPI, and MMC/SD interfaces.

Applications
