Key Parameters

Substitute Part Grouping Explanation

Substitution for the MSP430F110IPWR is determined by compatibility across the following critical parameters: core processor architecture (MSP430 CPU16), core size (16-Bit), operating speed (8MHz), package type (20-TSSOP), supply voltage range (1.8V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

The substitute parts identified maintain these core electrical and mechanical specifications while offering variations in program memory size and RAM capacity. Both substitute parts retain the same 20-TSSOP package footprint, identical I/O pin count (14), and equivalent thermal operating range, ensuring direct compatibility at the board level.

Parameter Comparison

Engineering Selection Recommendations

The MSP430F110IPWR is obsolete, necessitating substitution for new production and design continuations. Both substitute parts are active products with verified programmability status, ensuring long-term availability and supply chain stability.

MSP430F1101AIPWR is the direct functional equivalent, maintaining identical program memory (1KB) and RAM (128 x 8) specifications while offering increased FLASH overhead (256B vs. 128B). This part is available in Cut Tape and Digi-Reel packaging options and is recommended for applications requiring minimal memory footprint with maximum supply availability.

MSP430F112IPW provides expanded memory capacity with 4KB program memory and 256 x 8 RAM, suitable for applications requiring additional code space or data storage. This part is available in Tube packaging and is recommended when memory expansion is beneficial without requiring architectural changes.

All three parts maintain identical electrical characteristics, package geometry, pin configuration, and thermal operating range, ensuring drop-in compatibility at the circuit board level.

Frequently Asked Questions (FAQ)

Q: Can MSP430F1101AIPWR and MSP430F112IPW be used interchangeably with MSP430F110IPWR?

A: Both parts are electrically and mechanically compatible with the MSP430F110IPWR. They share identical core processor architecture, operating speed, supply voltage range, I/O pin count, and 20-TSSOP package footprint. Differences in program memory and RAM do not affect pinout or electrical interface compatibility.

Q: What are the key differences between the substitute parts?

A: MSP430F1101AIPWR maintains the original 1KB program memory specification with 256B FLASH overhead. MSP430F112IPW provides 4KB program memory and 256 x 8 RAM, offering expanded capacity for larger applications. Both retain the same 8MHz operating speed and 14 I/O pins.

Q: Are there peripheral differences between these parts?

A: The MSP430F110IPWR includes PWM functionality. The MSP430F1101AIPWR does not include PWM but includes a Slope A/D converter. The MSP430F112IPW includes PWM functionality. Applications requiring PWM should use MSP430F110IPWR or MSP430F112IPW.

Q: What packaging options are available for each substitute?

A: MSP430F1101AIPWR is available in Cut Tape (CT) and Digi-Reel packaging. MSP430F112IPW is available in Tube packaging. The MSP430F110IPWR original part packaging is not specified in available data.

Q: Are all parts RoHS and REACH compliant?

A: All three parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Which substitute should be selected for new designs?

A: MSP430F1101AIPWR is recommended for direct replacement of obsolete MSP430F110IPWR in existing designs. MSP430F112IPW is recommended for new designs requiring expanded memory capacity without changing the core MSP430x1xx architecture.
