PIC24FV08KM202-E/SS Overview
The PIC24F KM family is a low-power 16-bit microcontroller platform that builds on the legacy PIC24F architecture while adding nanoWatt XLP energy-management features. These microcontrollers are intended for battery-powered and energy-harvesting applications where the 16-bit instruction set, deterministic interrupt handling, and integrated analog peripherals reduce board space and bill-of-materials cost. The PIC24FV08KM202 specifically targets small-pin-count designs (28/36 SSOP/SOIC/SPDIP/QFN) running from 1.8 V to 5.5 V, with a maximum throughput of 16 MIPS at 32 MHz. The 16-bit core can address up to 64 KB of program space, and the KM variant adds peripherals commonly used in sensor interfaces and power-conversion loops.
Key features of the PIC24FV08KM202-E/SS include 23 general-purpose I/O pins, a 12-bit ADC with up to 500 ksps throughput, a 10-bit DAC, integrated op amps for signal conditioning, multiple 16-bit timers, a watchdog timer (WDT), brown-out reset (BOR), low-voltage detect (LVD), power-on reset (POR), PWM, I2C, SPI, and UART peripherals. The XLP sleep current is below 20 nA in deep sleep mode with RTCC running, and the device supports multiple low-power modes (Idle, Sleep, Deep Sleep) with multiple wake-up sources. The 28-SSOP package is the standard narrow-body 300 mil wide surface-mount outline used widely in industrial and consumer designs.
Typical applications include handheld medical devices, IoT sensor nodes, remote controls, energy-harvesting wireless sensor nodes, battery-powered instrumentation, smart metering, low-power motor control (PWM-driven small BLDC drivers), and general-purpose mixed-signal embedded systems. The integrated op amps and DAC simplify analog front-end designs, while the CTMU supports capacitive touch and time-of-flight measurements. The 1.8 V minimum supply enables direct connection to single-cell Li-Ion or two AA alkaline cells.
When designing with the PIC24FV08KM202-E/SS, ensure the supply decoupling uses a 10 uF tantalum and 0.1 uF ceramic pair close to the VDD/AVDD pins. The PGEC and PGED pins must be accessible for ICSP programming and in-circuit debugging using MPLAB ICD or MPLAB Snap. Reserve adequate ground pour under the package to support thermal dissipation in high-temperature industrial environments.

Typical Applications
PIC24FV08KM202-E/SS is suitable for 6 applications: Battery-Powered IoT Sensor Node, Handheld Medical / Wellness Device, Smart Metering / Energy Monitoring, Remote Control / HMI with Capacitive Touch, Low-Power Motor Control (Fan / Pump), Capacitive Touch Buttons / Slider (Industrial HMI).
Battery-Powered IoT Sensor Node
The PIC24FV08KM202-E/SS is well-suited for battery-powered IoT sensor nodes thanks to its 1.8 V to 5.5 V supply range and sub-20 nA deep-sleep current (XLP). Its integrated 12-bit ADC samples temperature, humidity, or analog sensor outputs without an external signal chain, while the CTMU supports capacitive touch or pulse-based time-of-flight sensing. The 16 MIPS throughput handles wake-up, sensor read, and radio hand-off via UART/SPI to sub-GHz transceivers. Compared with 8-bit PIC16 alternatives, the 16-bit core delivers 4x the arithmetic throughput for FFT or threshold detection algorithms.
Recommended
Handheld Medical / Wellness Device
The PIC24FV08KM202-E/SS targets handheld medical and wellness devices where the -40 C to +125 C extended grade supports sterilisation and storage-temperature swings, and the on-chip op amps front-end bioelectric sensors. Its integrated 10-bit DAC drives reference voltages or analog front-end bias, while the 12-bit ADC captures photodiode or impedance signals at 500 ksps. The 2 KB SRAM is sufficient for simple waveform analysis (pulse oximetry, heart-rate detection), and the XLP sleep current preserves battery life between measurements.
Recommended
Smart Metering / Energy Monitoring
The PIC24FV08KM202-E/SS is well-matched to residential smart-metering and energy-monitoring nodes. Its 12-bit ADC with 500 ksps throughput accurately samples current and voltage from a CT shunt or Rogowski coil, while the integrated op amps condition the sensor signals before digitization. The on-chip DAC outputs a calibration reference or generates waveforms for power-line communication. UART, I2C, and SPI peripherals connect to a metrology companion IC or to a sub-GHz RF modem for AMI backhaul.
Recommended
Remote Control / HMI with Capacitive Touch
The PIC24FV08KM202-E/SS integrates the Charge Time Measurement Unit (CTMU) which directly drives up to 23 capacitive-touch electrodes via firmware charge-time measurement, eliminating an external touch controller. The 32 MHz / 16 MIPS core runs mTouch or proprietary touch algorithms in real-time, while UART/SPI connects to an RF remote link. The 8 KB Flash supports multi-language button maps and gesture libraries, and the -40 C to +125 C operation ensures outdoor HMI reliability.
Recommended
Low-Power Motor Control (Fan / Pump)
The PIC24FV08KM202-E/SS handles low-power BLDC, brushed DC, or PWM-driven fan and pump control. Its 16-bit PWM modules provide up to multiple PWM outputs at 32 MHz resolution, the 12-bit ADC reads back-EMF or current feedback, and the integrated op amps condition current-sense shunts directly. The 1.8 V to 5.5 V range supports single-cell Li-Ion (1S) and 3.3 V/5 V system rails, while XLP sleep modes enable low standby when the motor is idle.
Recommended
Capacitive Touch Buttons / Slider (Industrial HMI)
The PIC24FV08KM202-E/SS is well-suited for industrial capacitive-touch HMI panels where the extended -40 C to +125 C temperature range ensures operation in factory environments. The CTMU measures charge times on multiple electrodes through dedicated analog muxes, supporting buttons, sliders, and proximity sensors. The 16-bit core runs mTouch or CTMU-based libraries while leaving headroom for HMI communication via UART, SPI, or I2C to a system controller or LCD driver.

Key Differentiators
- Wide 1.8 V to 5.5 V supply with on-chip 5 KB Flash regulator (FR) (vs PIC24FV08KM202-I/SS (same package, same die))
- Extended -40 C to +125 C (E grade) operation (vs PIC24FV08KM202-I/SS (industrial -40 C to +85 C))
- 2 KB SRAM for full feature firmware (vs PIC24FV08KM102-E/SS (1 KB SRAM))
Design Notes
Place a 10 uF tantalum and a 0.1 uF ceramic decoupling capacitor close to the VDD/AVDD pins (8/19 and 10) and a corresponding pair on VSS/AVSS (7/20/27 and 9). The wide 1.8 V to 5.5 V supply range permits direct battery operation, but the FR (Flash regulator) introduces a small quiescent draw - for low-duty-cycle battery applications, switch off the FR via firmware to enter nanoWatt XLP deep sleep (under 20 nA with RTCC running).
The 28-SSOP package has a typical theta_JA of approximately 80 C/W, limiting continuous power dissipation to roughly 150 mW at +25 C ambient without copper-pour heatsinking. For continuous high-current GPIO switching or ADC throughput at maximum sampling rate, route a continuous ground pour under the SSOP body and consider thermal vias to the inner PCB planes to keep the junction temperature below the +125 C limit (E grade).
Reserve access to PGEC1 (pin 5) and PGED1 (pin 4) for ICSP programming and ICD debugging using MPLAB SNAP or MPLAB ICD-4. Do not place these lines behind bus switches that are not transparent at startup. Provide a 4.7 k ohm pull-up on MCLR (pin 1) and a 10 nF capacitor to VSS as recommended by Microchip. Keep the PGEC/PGED traces short and surrounded by a ground guard pour to avoid noise coupling during debugging sessions.
Do not connect AVSS to a noisy digital ground - use a star ground topology with AVSS returning directly to the regulator reference point. When using the on-chip op amps, configure them after the ADC/DAC initialization to avoid spurious startup transients. The CTMU charge-time measurement requires the FR (Flash regulator) to be on; do not disable it during capacitive touch scanning or calibration will drift.
Compliance Information
