TUSB3210PMG4

Overview

The TUSB3210PMG4 is a Universal Serial Bus General-Purpose Device Controller manufactured by Texas Instruments. It integrates an 8052 microcontroller with 8K × 8 RAM for firmware, supporting USB 2.0 Full-Speed specifications at 12 Mbits/s. The device features four GPIO ports, a master I2C controller, and supports three input and three output endpoints. It operates from a 12-MHz crystal with an on-chip PLL generating 48 MHz. Power consumption includes 45 mA quiescent current and 45 µA in suspend mode. The component is housed in a 64-pin LQFP package.

Feature Summary

Fully compliant with USB 2.0 Full-Speed specifications (12 Mbits/s)
Integrated 8052 microcontroller with 8K × 8 RAM code space
Supports USB Suspend, Resume, and Remote Wake-Up operations
Includes Master I2C Controller and Watchdog Timer

Applications

Keyboards
Barcode Readers
Flash Memory Readers
General-Purpose Controllers

Procurement Notes

Verify the specific ordering suffix PMG4 against the manufacturer's latest orderable addendum to confirm package type and environmental compliance. Ensure compatibility with 3.3 V supply voltage requirements during system design. Confirm that the 64-pin LQFP footprint matches the target PCB layout guidelines provided in the datasheet thermal and mechanical sections.

Selection Notes

Select this controller for applications requiring a general-purpose MCU with integrated USB connectivity. The device supports booting from external EEPROM via I2C or direct download from a host PC. Designers must account for the 12-MHz crystal requirement and ensure proper decoupling for the 3.3 V supply. The available 8K RAM limits complex firmware implementations compared to larger microcontrollers.

Part Context

The TUSB3210 series serves as a bridge between USB hosts and peripheral devices without requiring a separate high-speed USB PHY. It allows manufacturers to create custom USB devices using standard 8052 development tools. The PMG4 variant specifically denotes the 64-pin LQFP package configuration suitable for surface-mount assembly.
