PIC24FV16KM202-E/SS Overview
What is a 16-bit microcontroller? A 16-bit MCU is a class of embedded processor that uses a 16-bit data path and instruction word, sitting between 8-bit MCUs (limited throughput) and 32-bit MCUs (higher power and cost). The PIC24F family is the mid-tier offering from Microchip, pairing 16-bit performance with low-power sleep modes, integrated analog, and a peripheral set aimed at sensor conditioning and battery-powered embedded products. The XLP variants add nanoWatt technology for sub-uA sleep currents.
Key features include a 32 MHz MIPS16e core, 16 KB Flash with self-programming support, 2 KB SRAM, 12-bit ADC with up to 500 ksps, three op-amps usable in transconductance/buffer configurations, a 5-bit DAC, multiple Capture/Compare/PWM modules, two UART/SPI/I2C modules (selectable), real-time clock calendar, and a Configurable Logic Cell that implements custom logic gates on-chip without external glue. The wide 2.0V to 5.5V operating range simplifies direct connection to 2xAA, Li-Ion, or 5V regulated rails.
Architecturally, the device uses a modified Harvard bus with separate instruction and data paths plus a hardware multiplier for DSP-style MAC operations. The CLC and peripheral pin-select (PPS) allow signal routing in software, reducing PCB routing complexity. The 12-bit ADC with internal bandgap reference and the integrated op-amps enable a complete analog front-end (sensor conditioning + ADC) on a single chip.
Typical applications include battery-powered sensor nodes, portable medical devices, IoT edge nodes, e-metering, low-power wireless sensor hubs (using SPI/UART peripherals), and industrial sensor transmitters. The combination of eXtreme Low Power sleep modes (down to ~30 nA in deep sleep with RTCC) and integrated analog makes this device particularly well suited to remote, energy-harvested or battery-cell applications.
When designing with the PIC24FV16KM202-E/SS, ensure decoupling capacitance of 100 nF is placed within 5 mm of each VDD/VSS pair, and configure the PPS registers to map peripherals to desired I/O. The 'E' suffix denotes the extended -40C to +125C industrial/automotive temperature grade; the 'FV' prefix denotes the wide 5.5V-tolerant Flash variant.

Typical Applications
PIC24FV16KM202-E/SS is suitable for 6 applications: Battery-Powered Sensor Node, Portable Medical Device, IoT Edge Node / Smart Home Sensor, Industrial Sensor Transmitter, Smart Energy / Metering, Automotive Body Electronics.
Battery-Powered Sensor Node
The PIC24FV16KM202-E/SS is purpose-built for battery-powered wireless sensor nodes that spend most of their life in deep sleep and wake briefly to read sensors and transmit. The XLP nanoWatt architecture delivers sleep currents in the tens of nanoamperes with RTCC, extending coin-cell or 2xAA battery life to multiple years. The wide 2.0V to 5.5V operating range accepts unregulated battery voltage directly, while the integrated 12-bit ADC, three op-amps, and 8-bit DAC support direct connection to sensors such as thermocouples, RTDs, and strain gauges. With 16 KB Flash and 32 MIPS throughput, the MCU runs Zigbee/LoRa stack fragments or simple custom protocols over the PPS-mappable UART/SPI/I2C modules.
Recommended
Portable Medical Device
The PIC24FV16KM202-E/SS fits portable medical devices such as glucose meters, pulse oximeters, and portable spirometers that demand low power, integrated analog precision, and a small PCB footprint. The 12-bit ADC with internal bandgap reference plus three integrated op-amps build a complete analog front-end for electrochemical or photodiode sensors, reducing BOM cost and board area. The 32 MHz MIPS core executes sensor fusion and display update routines while keeping average power consumption low enough for weeks of battery operation. The extended -40C to +125C temperature grade covers body-worn devices and pharmaceutical cold-chain monitoring.
Recommended
IoT Edge Node / Smart Home Sensor
IoT edge nodes such as smart thermostats, environmental sensors, and home appliance controllers benefit from the PIC24FV16KM202-E/SS's combination of XLP low power, integrated analog, and PPS-mappable peripherals. The Configurable Logic Cell implements custom combinational logic without external gates - implementing a window comparator or pulse-stretcher for energy metering entirely in silicon. The 28-pin SSOP keeps the PCB small enough to be embedded inside light-switch boxes or behind appliance panels. With nanoWatt sleep currents, the device can run for multiple years on a single CR2032 in duty-cycled IoT applications that report temperature or humidity every few minutes via a sub-GHz radio.
Recommended
Industrial Sensor Transmitter
Industrial 4-20 mA loop-powered sensor transmitters and battery-backed process instruments use the PIC24FV16KM202-E/SS's extended temperature grade (-40C to +125C), wide supply tolerance, and integrated analog to condition sensor outputs in the field. The device handles RTD/thermocouple amplification via the on-chip op-amps and digital conversion via the 12-bit ADC, all on a single chip with minimal external components. The UART peripherals connect to wireless modules or RS-485 transceivers for data offload, while the CLC implements HART or custom modems digitally. The 5.5V tolerant I/O simplifies interface to legacy industrial voltage levels.
Recommended
Smart Energy / Metering
Electronic energy meters, sub-metering devices, and AC line-monitoring products use the PIC24FV16KM202-E/SS for its integrated op-amps, ADC, and XLP sleep modes that fit battery-backed metering designs. The on-chip op-amps handle current-sense amplification directly, while the 12-bit ADC samples voltage and current channels with deterministic latency. The CLC implements zero-crossing detection and pulse counting for kWh/Wh accumulation without external logic. With 2 KB SRAM and 16 KB Flash, the MCU can host metering firmware plus small LCD drivers and tamper-detection routines.
Recommended
Automotive Body Electronics
The extended temperature grade and 5.5V supply tolerance make the PIC24FV16KM202-E/SS a candidate for non-safety automotive body electronics such as interior lighting controllers, seat-position memories, and HVAC control modules. The Configurable Logic Cell implements LIN-bus compatible framing or PWM-based body protocols, while the multiple PWM outputs drive LED dimming and small motor control. Designers building AEC-Q100 certified systems should select the '-I' industrial-grade PIC24FV16KM202-I/SS or equivalent Q-graded part for production. Note that for safety-critical automotive ECUs, an AEC-Q100 qualified part is required and the PIC24FV16KM202-E/SS may serve only as a non-safety auxiliary MCU.

Key Differentiators
- Wide 5.5V VDD tolerance for direct battery/USB connection (vs PIC24F16KM202-I/SS)
- Three integrated op-amps for single-chip analog front-end (vs PIC24FJ64GB202-I/SS)
- Configurable Logic Cell (CLC) for on-chip custom logic (vs PIC24FJ64GB202-I/SS)
- Extended -40C to +125C temperature grade as standard (vs PIC24FV16KM202-I/SS)
Design Notes
The PIC24FV16KM202-E/SS has multiple VDD/VSS pin pairs that must each be decoupled with 100 nF ceramic capacitors placed within 5 mm of each pin. For battery applications, use a low-Iq LDO such as MCP1700 (1.6 uA quiescent current) so the regulator Iq does not dominate the deep-sleep current budget of the MCU. Estimated: at 1.6 uA Iq LDO + 30 nA MCU deep-sleep with RTCC, total quiescent is approximately 1.63 uA - acceptable for coin-cell applications lasting several years.
The 28-pin SSOP has 0.65 mm lead pitch and requires careful PCB layout to avoid solder bridges during reflow. Use NSMD pads with a footprint slightly larger than the nominal land pattern, and ensure a solder mask dam between adjacent pads. Place the 32.768 kHz crystal within 5 mm of OSC1/OSC2 with short traces and a ground guard ring for low-EMI RTC operation. Estimated: at typical SSOP land pattern dimensions, conductive trace width within the spirit of IPC-7351 guidelines keeps above 0.2 mm.
The PIC24FV16KM202-E/SS uses Peripheral Pin Select (PPS) to remap digital peripherals to physical I/O pins. After boot, the firmware must configure PPS registers before using UART, SPI, I2C, or PWM outputs. Unused PPS-mappable pins should be configured as digital outputs driving low, and analog pins not in use should be set to analog mode to minimize digital switching noise coupling into the ADC input mux. Connect AVSS to VSS with a single star-point at the MCU to avoid ground loops affecting ADC accuracy.
Do not assume the 'E' grade and 'I' grade parts are interchangeable - the 'E' grade supports -40C to +125C while the 'I' grade is limited to -40C to +85C. For automotive AEC-Q100 applications, neither grade qualifies; choose a Q-suffix or AEC-Q100 qualified part instead. The 'FV' wide-voltage variant supports 5.5V VDD, but the non-FV 'F' variant (PIC24F16KM202) is limited to 3.6V - exceeding 3.6V on the 'F' variant will damage the device. Always configure unused I/O as outputs driving low to minimize power consumption in sleep modes.
