Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF2328VF25V is determined by alignment of the following critical parameters:

• Core Architecture: 16-bit processor core
• Program Memory: 256KB FLASH capacity
• Operating Speed: 25MHz clock frequency
• I/O Count: Minimum 86 I/O pins
• Supply Voltage Range: Compatibility within 2.7V to 3.6V envelope
• Package Type: Surface mount QFP/LQFP with 128 pins
• Memory Type: FLASH-based program memory
• Compliance: ROHS3 compliance and equivalent MSL rating

The MSP430F67461AIPEUR from Texas Instruments meets these substitution criteria. Both devices share identical core bit-width, program memory capacity, operating frequency, and package pin count. Both are ROHS3 compliant with equivalent moisture sensitivity ratings.

Parameter Comparison

Engineering Selection Recommendations

The MSP430F67461AIPEUR is a suitable substitute for the DF2328VF25V based on the following factors:

Compliance Alignment: Both devices maintain ROHS3 compliance and identical MSL ratings, ensuring equivalent environmental and regulatory standing.

Active Product Status: The MSP430F67461AIPEUR is classified as active, providing ongoing availability and manufacturer support, whereas the DF2328VF25V is obsolete.

Core Specifications: Both microcontrollers share identical 16-bit architecture, 25MHz operating frequency, and 256KB FLASH program memory capacity. Pin count is equivalent at 128 pins in surface mount QFP/LQFP packages.

Enhanced Capabilities: The MSP430F67461AIPEUR provides additional features including expanded RAM (16K x 8 versus 8K x 8), extended operating temperature range (-40°C to 85°C versus -20°C to 75°C), and lower minimum supply voltage (1.8V versus 2.7V). These enhancements do not conflict with legacy system requirements.

Package Consideration: Both devices use 128-pin QFP/LQFP packages with identical pin counts. Physical dimensions differ slightly (128-BFQFP 14x20 versus 128-LQFP 20x14), requiring PCB footprint verification during integration.

Frequently Asked Questions (FAQ)

Q: What makes the MSP430F67461AIPEUR a valid substitute for the DF2328VF25V?

A: Both devices share the critical parameters that define substitutability: 16-bit core architecture, 25MHz clock speed, 256KB FLASH program memory, 128-pin surface mount package, and ROHS3 compliance. These aligned specifications ensure functional equivalence for embedded control applications.

Q: Are there differences in I/O pin count between these devices?

A: The DF2328VF25V provides 86 I/O pins, while the MSP430F67461AIPEUR provides 90 I/O pins. The additional I/O on the substitute part does not create incompatibility; designs utilizing 86 pins will function with the substitute device.

Q: How do the package dimensions differ?

A: The DF2328VF25V uses a 128-BFQFP package (14x20mm), while the MSP430F67461AIPEUR uses a 128-LQFP package (20x14mm). Both are 128-pin surface mount packages. PCB footprint compatibility must be verified during design integration, as the physical dimensions are transposed.

Q: What is the significance of the RAM size difference?

A: The DF2328VF25V contains 8K x 8 RAM, while the MSP430F67461AIPEUR contains 16K x 8 RAM. The substitute provides double the RAM capacity, which is advantageous for applications requiring larger working memory and does not create backward compatibility issues.

Q: Does the extended operating temperature range of the MSP430F67461AIPEUR affect substitution?

A: The MSP430F67461AIPEUR operates from -40°C to 85°C, compared to the DF2328VF25V range of -20°C to 75°C. The extended range is a superset of the original specification and does not compromise substitution validity for systems operating within the original temperature envelope.

Q: Are there connectivity differences between these microcontrollers?

A: The DF2328VF25V features SCI and SmartCard connectivity. The MSP430F67461AIPEUR features I2C, IrDA, LINbus, SPI, and UART/USART connectivity. Peripheral compatibility depends on application-specific requirements and must be evaluated during system redesign.

Q: What is the supply voltage compatibility?

A: The DF2328VF25V requires 2.7V to 3.6V supply voltage. The MSP430F67461AIPEUR operates from 1.8V to 3.6V. Systems designed for the original device will function with the substitute within the overlapping 2.7V to 3.6V range.
