PIC24F08KM102-E/SS - 32MHz 8KB Low-Power MCU | Microchip
N.º de pieza: PIC24F08KM102-E/SS ✓ ActivoPIC24F08KM102-E/SS Descripción general
A microcontroller is a programmable semiconductor that combines a processor core, memory, and peripherals into one integrated circuit. The PIC24F08KM102 belongs to the PIC24F KM family of low-power embedded controllers, combining a 16-bit CPU architecture with analog signal-conditioning functions. This integration allows a product to measure analog inputs, generate an analog output, compare signals, and execute control logic without requiring several separate discrete components.
The principal specifications include a 32 MHz maximum operating frequency, 8 KB of flash memory organized as 2.75K by 24 bits, 1 KB of SRAM, and 512 bytes of EEPROM. The 12-bit ADC, comparator, DAC, and integrated op amps reduce the external component count in sensing and control designs. The E/SS ordering code denotes the extended-temperature surface-mount configuration in the 28-pin SSOP package.
The PIC24F architecture provides a compact, low-power platform for embedded control, and the KM family is specifically designed for applications operating from 1.8 V to 5.5 V. Analog peripherals share the device with digital control functions, so firmware must establish the required pin multiplexing, reference configuration, acquisition timing, and output settling sequence. The 28-pin SSOP also keeps the device footprint smaller than many larger microcontroller packages while retaining a conventional leaded surface-mount format.
Typical applications include industrial sensor nodes, building and environmental controls, compact battery-powered instruments, motor or valve controllers, and consumer products requiring both digital logic and limited analog signal handling. The 8 KB program-memory limit makes the device most appropriate for focused control tasks rather than connectivity stacks, graphics, or large protocol processing workloads.
Designers should verify every analog pin's multiplexed function in the pin-description table before assigning signals. Supply bypassing, analog grounding, and the configuration of unused inputs should follow the manufacturer’s recommended circuit. Because the MCU combines sensitive analog functions with digital peripherals, a clean supply reference and deliberate PCB return-current paths are important for repeatable measurement performance.
This product overview consolidates the essential memory, analog, package, and environmental characteristics into an engineering-focused selection reference. It also explains practical use cases, firmware and layout considerations, and the limits of drop-in alternatives so that a designer can evaluate this controller before committing it to a new PCB.

Aplicaciones típicas
PIC24F08KM102-E/SS es adecuado para 6 aplicacións: Industrial Sensor Node, Battery-Powered Environmental Monitor, Building and HVAC Control, Compact Motor and Valve Controller, Precision Analog Signal Conditioning, Consumer Appliance Control.
Industrial Sensor Node
The PIC24F08KM102-E/SS fits compact industrial sensor nodes that must acquire low-level analog measurements while retaining local decision logic. Its 12-bit ADC supports digital conversion of sensor outputs, while the comparator and integrated op amps can assist with thresholding, signal conditioning, and excitation control. The 16-bit CPU runs at up to 32 MHz, providing enough throughput for sampling, filtering, calibration, and communication updates without relying on a larger processor. Operation from 1.8 V to 5.5 V supports both low-voltage sensing and conventional industrial rails. The 28-SSOP package limits board area, but the final design must preserve analog-reference quality, route return currents away from measurement inputs, and provide local supply bypassing.
Recomendado
Battery-Powered Environmental Monitor
The PIC24F08KM102-E/SS is appropriate for battery-powered environmental monitors because it combines a 16-bit, 32 MHz control core with low-voltage operation from 1.8 V to 5.5 V. The integrated ADC can measure temperature, humidity, light, or gas-sensor outputs, while the EEPROM can retain calibration constants and counters across power cycles. Its local DAC can generate a reference or test signal, and the comparator can monitor a battery or system threshold without continuous software polling. Designers should select the extended-temperature grade when the enclosure experiences wide ambient variation and should calculate average current consumption from the final sleep and measurement duty cycle rather than active-clock performance alone.
Recomendado
Building and HVAC Control
The PIC24F08KM102-E/SS can implement compact building-control nodes for temperature, occupancy, light, or airflow feedback. Its 32 MHz 16-bit processor supports timed sampling, filtering, hysteresis, and state-machine logic, while the 12-bit ADC handles analog sensor inputs and the comparator supports simple threshold events. Integrated op amps may condition signals locally, reducing board area in space-constrained controllers. The 28-SSOP package is useful for small sensor modules, but the design should reserve programming access and observe the -40 °C to +125 °C rating when installed near HVAC equipment, motors, or outdoor control boxes.
Recomendado
Compact Motor and Valve Controller
The PIC24F08KM102-E/SS can serve as the supervisory controller in compact motor, valve, or actuator modules where firmware must coordinate digital I/O with analog feedback. Its 16-bit CPU at up to 32 MHz can execute position loops, timing sequences, fault detection, and current-limit management, while the ADC and comparator monitor sensor or drive-voltage conditions. The 1.8 V to 5.5 V operating range supports mixed-voltage systems when external regulation and protection are used. Because the MCU does not include a large power stage, motor current transients and switching noise must be isolated from the analog section through appropriate layout, grounding, filtering, and drive circuitry.
Recomendado
Precision Analog Signal Conditioning
The PIC24F08KM102-E/SS is suitable for compact analog signal-conditioning products that combine measurement, comparison, and output control. The integrated 12-bit ADC provides a digital measurement channel, the DAC can generate a controllable analog output, and the comparator supports fast threshold decisions. Internal op amps can implement basic gain, buffering, or filtering stages when their electrical limits suit the signal. This consolidation may reduce component count, but it does not eliminate the need to review input impedance, output loading, bandwidth, offset, and settling requirements. Firmware should configure the selected peripheral and pin multiplexing explicitly, while the PCB should isolate sensitive analog routing from digital activity.
Recomendado
Consumer Appliance Control
The PIC24F08KM102-E/SS can control compact consumer appliances where a microcontroller must interpret switches or sensors, drive indicators or actuators, and support simple analog adjustments. Its 8 KB of flash and 1 KB of RAM are suitable for dedicated control logic, while the integrated ADC, comparator, DAC, and op amps can reduce the number of support ICs. The 28-SSOP package supports compact PCB layouts, and the -40 °C to +125 °C version covers a broad range of ambient conditions. Firmware planning should account for the limited memory budget, and the layout should separate relay or load-switching transients from sensitive analog and microcontroller supply paths.

Notas de diseño
Place the required decoupling capacitors directly beside the PIC24F08KM102-E/SS supply and ground pins, following the manufacturer’s recommended circuit rather than substituting generic bulk capacitors. Keep analog reference and signal-ground paths continuous, and route high-current load returns away from the MCU and ADC input region. The 0.209 mm lead pitch requires a capable assembly process, controlled solder-paste volume, and careful inspection between closely spaced pins.
Assign ADC, comparator, DAC, and op-amp functions only after reviewing the 28-pin SSOP multiplexing table. Many analog functions share pins with digital I/O, so incorrect direction or peripheral-selection settings can create contention or disturb measurements. Use the shortest practical analog traces, provide a stable reference, avoid switching-node routing beneath analog inputs, and verify source impedance and acquisition time for the selected ADC channel.
Estimated power-budget method: multiply the measured supply current by the actual input voltage for each operating mode, then compare the resulting watts with the thermal design at the highest ambient temperature. The 1.8 V to 5.5 V operating range does not mean that 5.5 V is appropriate for every design; select the minimum rail that supports the peripherals and I/O levels. Include startup, ADC sampling, and worst-case communication activity in the average-current calculation.
Do not treat the E/SS and I/SS temperature suffixes as interchangeable when the enclosure can exceed 85 °C, and do not assume that a same-package family member has identical flash, RAM, EEPROM, or peripheral assignments. Confirm the programming configuration, boot behavior, pin multiplexing, and memory map for the selected MPN. A mechanical fit alone does not establish firmware and electrical compatibility.
