Key Features
- 16-bit PIC24F core running up to 32 MHz with nanoWatt XLP sleep current below 20 nA for battery-powered designs
- Wide 1.8 V to 3.6 V operating range with full 32 MHz speed available from 1.8 V at 8 MHz
- Integrated 10-bit ADC with up to 9 channels plus UART, SPI, and I2C serial interfaces in a compact SOIC-28 footprint
Applications
The PIC24F16KL402-I/SO is well-suited for portable medical devices, wireless sensor nodes, and smart utility meters where ultra-low sleep currents below 20 nA extend battery life significantly. Its 1.8 V operating capability makes it compatible with modern 1.8 V flash memories and RF transceivers without additional level shifters. The SOIC-28 package fits standard PCB layouts and allows hand-soldering during prototyping.

Frequently Asked Questions
What is the minimum operating voltage for PIC24F16KL402-I/SO, and what clock speed is available at that voltage?
The PIC24F16KL402-I/SO operates from a minimum of 1.8 V, at which point it can run at up to 8 MHz. The full 32 MHz is available from 2.0 V and above, allowing designers to scale clock frequency with supply voltage to optimize the power-versus-performance trade-off in battery-operated systems.
How much non-volatile program storage does PIC24F16KL402-I/SO provide, and how does that limit firmware complexity?
The PIC24F16KL402-I/SO provides 16 KB of flash program memory and 1 KB of SRAM. The 16-bit instruction set with 48 KB addressable program space means 16 KB of flash stores roughly 5,000 to 6,000 16-bit instructions, sufficient for moderate sensor fusion, communication stacks, or simple control algorithms but not for larger RTOS-based applications.
For a compact remote sensor PCB, does the SOIC-28 package of PIC24F16KL402-I/SO support reflow soldering alongside SMD passives?
Yes. The SOIC-28 package has a 1.27 mm lead pitch and a 7.50 mm body width, making it fully compatible with standard SMT reflow processes. It can be placed and soldered alongside 0402 and 0603 passives on the same board pass, and its MSL rating allows storage and processing under normal warehouse humidity conditions without baking.
