PIC24FV08KM101-E/SS - 16-Bit 32MHz XLP MCU | Microchip
MPN: PIC24FV08KM101-E/SS ✓ ActivePIC24FV08KM101-E/SS Overview
A low-power microcontroller, or MCU, is a single integrated circuit containing a processor core, nonvolatile program memory, data memory, and peripherals such as analog converters and communication modules. The PIC24F family combines a 16-bit architecture with XLP low-power design techniques. The PIC24FV08KM101-E/SS is designed for compact control systems operating from 2 V to 5 V where flash program memory, EEPROM data retention, and analog signal conditioning are required in a small package.
The device provides 17 I/O pins and an integrated 12-bit ADC, comparator, and communication capabilities identified as MCCP and SCCP. Its 8 KB flash is organized as 2.75K × 24 words, while the 1 KB RAM is organized as 1K × 8 bytes and EEPROM is organized as 512 × 8 bytes. These resources support compact control loops, parameter storage, sensor acquisition, and low-duty-cycle embedded routines without requiring a separate external memory device.
The PIC24F KM family is positioned around low-power operation from 1.8 V to 5.5 V in the family description, while the PIC24FV08KM101-E/SS listing specifies a 2 V to 5 V device configuration. Its 32 MHz performance ceiling, 16-bit instruction-oriented architecture, and integrated analog resources allow the MCU to consolidate functions that might otherwise require separate analog and communication ICs.
Typical uses include industrial sensor nodes, compact motor and pump controllers, building-automation modules, low-power measurement instruments, and battery-operated monitoring equipment. The extended-temperature grade makes it appropriate for equipment exposed to temperature variation beyond a standard industrial temperature range, subject to the limits stated in the manufacturer documentation.
PCB designers should treat all 17 I/O pins and the analog functions as resource-constrained because the 20-pin SSOP offers limited escape routing. Place the decoupling capacitor close to VDD and VSS, route analog inputs away from switching nodes, and verify the pin multiplexing table before assigning a peripheral function to a specific pin.
This page combines the device specifications, application guidance, temperature-grade comparisons, and pin-compatible alternatives in one place. It also distinguishes exact electrical drop-in substitutions from variants that require firmware, qualification, or layout review before being treated as equivalent.

Typical Applications
PIC24FV08KM101-E/SS is suitable for 6 applications: Industrial Sensor Nodes, Compact Motor and Pump Control, Building Automation and HVAC Modules, Battery-Powered Monitoring Devices, Low-Power Measurement Instruments, Small Consumer and Appliance Controllers.
Industrial Sensor Nodes
The PIC24FV08KM101-E/SS suits compact industrial sensor nodes because it combines a 12-bit ADC, comparator, 17 I/O pins, and EEPROM in one 20-pin device. The 512-byte EEPROM can retain calibration coefficients or configuration records without an external memory chip, while 8 KB of flash accommodates acquisition, filtering, and communication routines. Its 2 V to 5 V operating range supports regulated sensor rails, and the -40°C to +125°C grade covers extended-temperature equipment. Designers should still validate the sensor signal range, ADC input topology, and digital interface timing against the manufacturer datasheet.
Recommended
Compact Motor and Pump Control
The PIC24FV08KM101-E/SS can serve as the control MCU in a small motor, pump, or valve module where space and standby power are constrained. Its 16-bit architecture and 32 MHz maximum performance support timer-based control loops, while the comparator can monitor a current or feedback signal against a reference. Seventeen I/O pins provide connections for gate-drive control, fault inputs, and status indicators. Because the SSOP footprint has limited routing space, assign the highest-speed timer and fault signals before optional digital outputs, and account for switching-node coupling in the analog layout.
Recommended
Building Automation and HVAC Modules
The PIC24FV08KM101-E/SS fits building-automation modules that combine local sensing with low-power serial communication. Its integrated 12-bit ADC reads temperature, light, or air-quality transducers, while MCCP and SCCP peripherals support serial connectivity according to the device configuration. The 1 KB RAM and 8 KB flash are adequate for compact protocol handling and supervisory logic, and EEPROM can retain node settings. Choose external interface transceivers only when the required bus voltage, isolation, or drive strength exceeds the MCU pins.
Recommended
Battery-Powered Monitoring Devices
The PIC24FV08KM101-E/SS is appropriate for battery-powered environmental monitors where a small footprint, low supply voltage, and local data retention are important. Its XLP family heritage supports low-duty-cycle firmware strategies, while on-chip EEPROM avoids occupying flash for small configuration changes. The MCU can wake periodically, sample a sensor with the 12-bit ADC, evaluate the comparator threshold, and transmit a result through an available serial peripheral. Average-current targets depend on the selected clock, peripheral configuration, and sleep mode, so measure the complete duty cycle rather than estimating from active current alone.
Recommended
Low-Power Measurement Instruments
The PIC24FV08KM101-E/SS supports compact measurement instruments that need analog acquisition, nonvolatile configuration storage, and modest compute performance in one package. The 12-bit ADC handles sensor digitization, the comparator provides fast threshold events, and 512 bytes of EEPROM can hold calibration or instrument settings. Eight kilobytes of flash is sufficient for a focused application rather than a large graphical or protocol-heavy system. For precision analog work, pay particular attention to the analog-reference arrangement, grounding strategy, and the separation of analog and switching-capacitor nodes.
Recommended
Small Consumer and Appliance Controllers
The PIC24FV08KM101-E/SS can control compact appliances, timers, and user-interface subsystems that combine a few inputs with analog sensing. Its 17 I/O pins support buttons, indicators, relays, and display segments, while the ADC and comparator reduce external component count. The 20-SSOP package also simplifies cost-focused PCB layouts compared with larger leaded packages. Firmware should include debouncing and safe-state defaults for relay or actuator outputs, and the final product must verify the chosen -E temperature grade against its enclosure temperature and manufacturing process.

Key Differentiators
- Extended-temperature operation within the same 20-SSOP footprint (vs PIC24FV08KM101-I/SS)
- Integrated analog and communication resources in a 20-pin package (vs PIC24F08KM101-E/SS)
- Local nonvolatile storage reduces external component count (vs PIC24FV08KM101-I/SS)
Design Notes
Treat the 20-pin SSOP footprint as a constrained routing exercise. Assign the power, ground, programming, and highest-value peripheral pins before optional user I/O because only 17 I/O positions are available. Follow the manufacturer recommended decoupling arrangement, place the supply capacitor at the device pins, and use a continuous ground plane. Validate the land pattern against the mechanical drawing for the exact SSOP ordering code before releasing artwork.
Separate analog inputs from switching-capacitor and high-current digital nodes, especially when the 12-bit ADC is used near fast timers or communication outputs. Return analog references to a clean ground path and keep input traces short. The integrated comparator can respond faster than the ADC, so it is useful for threshold protection, but comparator input filtering and hysteresis must be evaluated in firmware and hardware.
The MCU operates from 2 V to 5 V, so confirm that every attached peripheral shares a compatible voltage domain or has level translation. Keep analog and digital supply paths controlled to prevent switching activity from disturbing the ADC and comparator. For low-duty-cycle designs, explicitly configure unused peripherals and pins before entering the selected sleep mode; actual average current depends on clock settings and the duty cycle.
Do not approve a substitution based only on matching memory capacity and package size. PIC24F and PIC24FV family devices can differ in peripheral details, and -E, -I, and -T ordering suffixes can carry different temperature or grade requirements. Compare the device identification, peripheral feature matrix, pin multiplexing, electrical limits, and qualification records before releasing a replacement to production.
Compliance Information
