TUSB3210PM

Overview

The TUSB3210PM is a USB-based general-purpose device controller from Texas Instruments, housed in a 64-pin LQFP package. It integrates an 8052 microcontroller with 8K × 8 RAM for firmware development and 512 bytes of shared RAM for data buffers. The device supports USB 2.0 Full-Speed specifications at 12 Mbits/s and includes four GPIO ports, a master I2C controller, and a watchdog timer. Operating from a 12-MHz crystal with an on-chip PLL generating 48 MHz, it functions within a 3 V to 3.6 V supply range and an operating temperature of 0°C to 70°C.

Feature Summary

• Integrates an 8052 MCU with 8K × 8 RAM code space and 512 bytes shared RAM
• Fully compliant with USB 2.0 Full-Speed (12 Mbits/s) specifications
• Includes four 8052 GPIO ports and a master I2C controller
• Supports booting from external EEPROM via I2C or direct host download via USB

Applications

• Keyboards
• Barcode readers
• Flash memory readers
• General-purpose controllers

Procurement Notes

Verify the specific suffix PM corresponds to the 64-pin LQFP package configuration. Confirm that the required firmware development tools are compatible with the integrated 8052 architecture. Ensure the design accounts for the 12-MHz crystal requirements and the 3.3 V nominal supply voltage constraints specified in the recommended operating conditions.

Selection Notes

Select this component when a combined USB interface and microcontroller solution is required to minimize board space. It is suitable for applications needing programmable VID/PID selection without external EEPROM storage. Consider the 64-pin LQFP footprint and thermal resistance characteristics during PCB layout planning.

Part Context

The TUSB3210 series serves as a versatile USB controller targeting general-purpose MCU applications. The TUSB3210PM variant specifically denotes the 64-pin Low-Profile Quad Flat Package (LQFP). This family allows for flexible application development by supporting both I2C-based booting from external memory and direct USB programming from a host PC.

Replacement Considerations

Direct pin-to-pin replacements are not explicitly listed in the provided documentation. Evaluate other devices within the Texas Instruments USB controller portfolio for functional compatibility, ensuring equivalent 8052 core integration and USB 2.0 Full-Speed support.
