TUSB3200ACPAHR

Overview

The TUSB3200ACPAHR is a USB streaming controller manufactured by Texas Instruments, designed for managing USB data flow in embedded systems. It integrates an 8052 core processor with 4kB of ROM and 8.25K x 8 bytes of RAM. The device supports I2C and USB interfaces, operating within a supply voltage range of 3V to 3.6V. It features two I/O lines and is housed in a 52-TQFP package (10x10 mm) suitable for surface mount installation. The component functions as an application-specific microcontroller optimized for USB signal control tasks.

Feature Summary

• Integrated 8052 core processor with 4kB ROM and 8.25K x 8 RAM
• Dual interface support for I2C communication and USB streaming control
• Operates on a 3V to 3.6V power supply with standard surface mount packaging

Applications

• USB signal flow control in embedded devices
• Application-specific microcontroller implementations requiring USB management

Procurement Notes

Verify the part status carefully, as public records indicate this specific model may be discontinued or subject to product change notices. Confirm the exact suffix 'R' corresponds to the reel packaging variant and matches the required 52-TQFP form factor. Check for any RoHS3 compliance documentation if environmental regulations apply to the target assembly process.

Selection Notes

Select this component when a dedicated hardware solution for USB streaming control is required alongside basic processing capabilities. Ensure the design accommodates the 52-TQFP footprint and the 3V-3.6V voltage domain. Consider the availability constraints given the discontinuation status; evaluate if the integrated 8052 core meets the specific logic requirements without needing external memory expansion.

Part Context

This part belongs to the TUSB3200 series of USB controllers from Texas Instruments. It serves as a specialized interface solution combining microcontroller functionality with USB protocol handling. The 'CPAH' designation typically refers to the commercial temperature range and lead-free TQFP package, while the 'R' suffix denotes tape-and-reel packaging for automated assembly.

Replacement Considerations

Public sources list TUSB3200ACPAHG4 as a related variant within the same family. Verify functional equivalence and pin compatibility before substitution. Due to the discontinued status, alternative USB controllers from other manufacturers may require significant schematic and firmware redesign.
