PIC24F16KM104-I/MV Equivalent & Substitute Parts

Part Overview

The PIC24F16KM104-I/MV is a 16-bit microcontroller from Microchip Technology's PIC® XLP™ 24F series, featuring 16KB of FLASH program memory, 1KB of RAM, and 512 bytes of EEPROM. This device operates at 32MHz with integrated connectivity options including I2C, IrDA, LINbus, SPI, and UART/USART interfaces. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. Substitute parts must maintain core processor architecture, memory configuration, and peripheral functionality while accommodating packaging and voltage specification differences.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIC24F16KM104-I/MV is determined by strict alignment of the following core parameters:

• Core Processor Architecture: Must be PIC 16-bit processor
• Memory Configuration: 16KB FLASH program memory, 1KB RAM, 512 bytes EEPROM
• Operating Speed: 32MHz clock frequency
• Peripheral Set: I2C, IrDA, LINbus, SPI, UART/USART connectivity and Brown-out Detect/Reset, LVD, POR, PWM, WDT functions
• Data Converter Specification: A/D 22x10b/12b
• Temperature Range: -40°C ~ 85°C operating specification
• Series Classification: PIC® XLP™ 24F family membership

Variations in packaging format (UQFN vs. QFN), I/O pin count, voltage supply range, and product status do not disqualify functional equivalence when all core parameters align. The substitute part PIC24FV16KM104-I/ML meets these criteria despite differences in package type and I/O configuration.

Parameter Comparison

Engineering Selection Recommendations

The PIC24FV16KM104-I/ML qualifies as a functional equivalent to the obsolete PIC24F16KM104-I/MV based on identical core processor architecture, memory configuration, operating speed, peripheral set, and data converter specifications. Both devices maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for production applications.

The substitute part offers the advantage of active product status, providing assured long-term availability and manufacturing support. The expanded voltage supply range (2V ~ 5V versus 1.8V ~ 3.6V) accommodates broader system integration scenarios. The one-pin reduction in I/O count (37 versus 38) and package format change from 48-UQFN to 44-QFN require PCB layout and schematic revision but do not affect functional capability when all 37 available I/O pins satisfy application requirements.

Selection of the PIC24FV16KM104-I/ML is appropriate for new designs and production continuity where the specified I/O pin count and packaging format are compatible with system architecture.

Frequently Asked Questions (FAQ)

Q: What makes PIC24FV16KM104-I/ML a valid substitute for PIC24F16KM104-I/MV?

A: Both devices share identical PIC 16-bit core processor architecture, 16KB FLASH program memory, 1KB RAM, 512-byte EEPROM, 32MHz operating speed, and complete peripheral set including I2C, IrDA, LINbus, SPI, UART/USART connectivity. Core functional equivalence is established through these matching specifications.

Q: How do the packaging differences affect substitution?

A: The main part uses 48-UQFN (6x6) packaging with 38 I/O pins; the substitute uses 44-QFN (8x8) packaging with 37 I/O pins. These differences require PCB layout and schematic redesign but do not affect functional capability if the application requires 37 or fewer I/O pins.

Q: What is the significance of the voltage supply range difference?

A: The main part operates at 1.8V ~ 3.6V; the substitute operates at 2V ~ 5V. The substitute's expanded upper voltage limit (5V) provides compatibility with broader system power architectures. Applications operating within the 1.8V ~ 3.6V range remain fully compatible with the substitute.

Q: Why is product status relevant to substitution?

A: The main part is classified as obsolete, indicating discontinued manufacturing and limited availability. The substitute is active, ensuring ongoing production support and long-term component availability for design continuity and production scaling.

Q: Are there any compliance or certification differences?

A: Both parts maintain identical ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating. No compliance or certification barriers exist for substitution.
