• Manufacturer Alignment: Both parts are Texas Instruments products within the TUSB controller series
• Core Processor Compatibility: Both utilize the 8052 core processor architecture
• Supply Voltage Range: Both operate within the 3V to 3.6V supply voltage specification
• Interface Protocol Support: Both support USB communication protocols required for controller applications
• Compliance Standards: Both maintain ROHS3 compliance and REACH unaffected status
• Manufacturing Status: Both parts are classified as obsolete, indicating end-of-life status

The TUSB3410IRHB represents an enhanced variant with expanded memory capacity and extended operating temperature range, suitable for applications requiring the TUSB3210PMG4 functionality.

Parameter Comparison

Engineering Selection Recommendations

Selection between the TUSB3210PMG4 and TUSB3410IRHB is based on the following engineering criteria:

TUSB3210PMG4 is appropriate for applications where existing inventory exists and system redesign is not feasible. The 64-LQFP package and EEPROM memory configuration define the original design specification.

TUSB3410IRHB is the designated manufacturer substitute and is suitable for new designs, system refreshes, or inventory replenishment. This part offers expanded RAM capacity (18K x 8 versus 8K x 8), extended operating temperature range (-40°C to 85°C versus 0°C to 70°C), and additional interface options (I2C, USB, UART versus Serial EEPROM). The smaller 32-VQFN package reduces board footprint. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the TUSB3410IRHB directly replace the TUSB3210PMG4 without firmware modification?

A: Both parts share the 8052 core processor and 3V to 3.6V supply voltage specification. However, the TUSB3410IRHB features different memory architecture (ROM versus EEPROM) and expanded RAM capacity. Firmware compatibility depends on application-specific code requirements and memory utilization patterns. PCB layout changes are required due to package differences (64-LQFP versus 32-VQFN).

Q: What are the package differences between these parts?

A: The TUSB3210PMG4 uses a 64-LQFP package measuring 10x10mm, while the TUSB3410IRHB uses a 32-VQFN package measuring 5x5mm. The TUSB3410IRHB package is significantly smaller, reducing board area requirements. PCB footprint redesign is necessary for substitution.

Q: Are both parts suitable for industrial temperature applications?

A: The TUSB3210PMG4 operates from 0°C to 70°C, limiting use to commercial temperature ranges. The TUSB3410IRHB operates from -40°C to 85°C, supporting extended industrial and automotive temperature requirements. Selection depends on application environmental specifications.

Q: Do both parts maintain the same compliance certifications?

A: Both the TUSB3210PMG4 and TUSB3410IRHB are ROHS3 compliant and REACH unaffected. Compliance status is equivalent between the two parts.

Q: What interface differences exist between these controllers?

A: The TUSB3210PMG4 provides Serial EEPROM interface capability. The TUSB3410IRHB expands interface support to include I2C, USB, and UART protocols. Application requirements determine whether expanded interface options are beneficial or unnecessary.
