TUSB3210PM USB Microcontroller Equivalent & Substitute Parts

Part Overview

The TUSB3210PM is an embedded USB microcontroller manufactured by Texas Instruments, designed for USB storage and control applications. This device integrates an 8052 core processor with 8K x 8 RAM and EEPROM program memory, operating at 3V to 3.6V supply voltage. The TUSB3210PM is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TUSB3210PM is determined by the following critical parameters:

Core Compatibility Criteria:

• Manufacturer: Texas Instruments (TUSB controller series)
• Core Processor: 8052 architecture
• Voltage Supply Range: 3V ~ 3.6V
• RoHS3 Compliance: Required for regulatory alignment
• Surface Mount Technology: Maintained for PCB integration

Functional Considerations: The TUSB3410IRHB serves as the manufacturer-recommended substitute. While this device operates within the same voltage range and maintains 8052 core architecture, it functions as a USB serial port controller rather than a storage controller. The TUSB3410IRHB provides expanded RAM (18K x 8 versus 8K x 8), extended operating temperature range (-40°C ~ 85°C), and multiple interface options (I2C, USB, UART) compared to the TUSB3210PM's Serial EEPROM interface.

Package Consideration: The substitute part uses a 32-VQFN (5x5) package, which differs from the original 64-LQFP (10x10) package. This represents a significant physical footprint change requiring PCB redesign.

Parameter Comparison

Engineering Selection Recommendations

Selection of TUSB3410IRHB as a substitute for TUSB3210PM is based on the following engineering factors:

Regulatory Compliance: Both devices maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and commercial applications.

Voltage Compatibility: Identical supply voltage range (3V ~ 3.6V) permits direct electrical integration without additional power conditioning.

Processor Architecture: Both devices utilize the 8052 core processor, providing firmware compatibility potential for applications not dependent on storage-specific functionality.

Temperature Operating Range: The TUSB3410IRHB extends the operating temperature range to -40°C ~ 85°C, accommodating broader environmental conditions compared to the TUSB3210PM's 0°C ~ 70°C range.

Memory Configuration: The TUSB3410IRHB provides increased RAM capacity (18K x 8) and ROM-based program memory, suitable for applications requiring expanded data buffering and fixed firmware storage.

Physical Integration: Package change from 64-LQFP to 32-VQFN requires PCB layout modification and represents the primary design constraint for substitution implementation.

Frequently Asked Questions (FAQ)

Q: Can TUSB3410IRHB directly replace TUSB3210PM without PCB modification?

A: No. The TUSB3410IRHB uses a 32-VQFN (5x5) package compared to the TUSB3210PM's 64-LQFP (10x10) package. PCB footprint redesign is required. Pin count reduction from 64 to 32 necessitates functional reassessment of I/O requirements.

Q: Are the firmware and software compatible between these devices?

A: Both devices use the 8052 core processor. However, the TUSB3210PM features EEPROM program memory while the TUSB3410IRHB uses ROM. Applications dependent on in-system firmware reprogramming require evaluation of the ROM-based architecture.

Q: What is the primary functional difference between these controllers?

A: The TUSB3210PM functions as a USB storage controller with Serial EEPROM interface. The TUSB3410IRHB operates as a USB serial port controller with I2C, USB, and UART interfaces. Application requirements determine functional suitability.

Q: Are both devices still available for procurement?

A: Both devices are classified as obsolete. Inventory availability through authorized distributors should be verified before design commitment.

Q: What are the moisture sensitivity implications for assembly?

A: The TUSB3210PM has MSL 3 (168 Hours) rating, while the TUSB3410IRHB has MSL 2 (1 Year) rating. The TUSB3410IRHB provides extended moisture protection, reducing bake-out requirements during assembly processes.

Q: Can the voltage supply range be extended beyond 3V ~ 3.6V for either device?

A: No. Both devices are specified for 3V ~ 3.6V operation. Supply voltage outside this range voids device specifications and reliability guarantees.
