PIC24F08KM202-I/SS - 16-Bit 32MHz MCU | Microchip Technology
N.º de pieza: PIC24F08KM202-I/SS ✓ ActivoPIC24F08KM202-I/SS Descripción general
A PIC24 microcontroller combines a 16-bit RISC architecture, digital signal processing instructions, and low-power XLP design techniques in a single integrated circuit. It sits within Microchip's broader microcontroller hierarchy as a compact embedded-control device intended for applications that require moderate processing performance, analog measurement, and programmable logic without an external system-on-chip.
The principal features of the PIC24F08KM202-I/SS include 8 KB of Flash memory for firmware, 2 KB of SRAM, a 12-bit analog-to-digital converter, and an 8-bit digital-to-analog converter. Integrated operational amplifiers reduce the need for external analog buffers, while the Configurable Logic Cell adds hardware-assisted logic functions without consuming general-purpose peripheral resources.
The analog-rich architecture makes this MCU suitable for sensor conditioning, control-loop monitoring, and compact industrial control products. Its 32 MHz maximum instruction speed provides deterministic execution for protocol handling, digital filtering, and actuator control. Operation from 1.8 V to 5.5 V supports both low-voltage energy-conscious systems and conventional 3.3 V or 5 V industrial equipment.
Typical uses include environmental sensors, small motor controllers, battery-powered measurement instruments, programmable logic controllers, and analog monitoring nodes. Designers can combine the ADC with the integrated amplifiers for direct sensor interfacing and use the DAC for analog output, reference generation, or control-loop excitation without expanding the board footprint.
When laying out the circuit, treat analog and digital return currents as separate paths and place bypass capacitors close to the supply pins. Confirm the exposed analog-pin multiplexing, comparator functions, and peripheral assignments against the manufacturer pin-description table before assigning PCB nets. Program memory limitations must also be considered when adding protocol stacks or bootloader functions.

Aplicaciones típicas
PIC24F08KM202-I/SS es adecuado para 6 aplicacións: Low-Power Environmental Sensor Node, Compact Analog Control Module, Battery-Powered Measurement Instrument, Programmable Logic Controller, Precision Signal Conditioning, Small Motor and Actuator Controller.
Low-Power Environmental Sensor Node
The PIC24F08KM202-I/SS fits compact environmental sensor nodes because its 12-bit ADC, integrated operational amplifiers, and 1.8 V to 5.5 V operating range support low-voltage measurement systems. The 16-bit core executes filtering and compensation at up to 32 MHz while XLP techniques limit active current in duty-cycled designs. The 8-bit DAC can also drive a sensor excitation or calibration reference. With 8 KB of Flash and 2 KB of RAM, the device is best suited to focused sensing, local thresholding, and short low-bandwidth communication rather than large protocol stacks.
Recomendado
Compact Analog Control Module
The PIC24F08KM202-I/SS is suitable for compact analog control modules that must measure a real-world signal, apply correction, and generate an analog correction output. Its 12-bit ADC captures control inputs, the integrated operational amplifiers can condition sensor signals, and the 8-bit DAC provides a programmable output without requiring a separate converter IC. At 32 MHz, the 16-bit architecture supports digital filtering, error computation, and deterministic actuator updates while the 2 KB of RAM is sufficient for small working buffers.
Recomendado
Battery-Powered Measurement Instrument
The PIC24F08KM202-I/SS supports battery-powered measurement instruments where analog performance, processing capability, and board area must coexist. Its operation from 1.8 V to 5.5 V accommodates single-cell-derived rails, while the integrated ADC, DAC, and operational amplifiers reduce external component count. The XLP architecture and 32 MHz execution speed allow the controller to alternate between fast sampling bursts and low-power idle periods. Firmware capacity should be planned carefully because the available 8 KB of Flash may not accommodate extensive graph-storage or connectivity features.
Recomendado
Programmable Logic Controller
The PIC24F08KM202-I/SS can serve as the core of a small programmable logic controller for machine monitoring, discrete sequencing, and analog threshold supervision. Its Configurable Logic Cell handles hardware-assisted logic functions, reducing polling demands on the CPU, while the 16-bit core manages timers, input scanning, and control-state updates. The 12-bit ADC permits direct analog supervision of supply voltage, temperature sensors, or process inputs. The 28-pin SSOP footprint supports cost-sensitive control boards that need mixed analog and digital functions without a larger package.
Recomendado
Precision Signal Conditioning
The PIC24F08KM202-I/SS is applicable to signal-conditioning front ends that require analog amplification and digital correction in one controller. The integrated operational amplifiers can support buffering and gain stages near the 12-bit ADC, reducing sensitive analog traces and board area. Its 32 MHz 16-bit processor can implement digital correction, calibration tables, and filtering after conversion. The 8-bit DAC can produce excitation or test waveforms for sensor characterization. Because the 8-bit DAC is intended for lower-resolution output needs, applications requiring high-fidelity analog generation should use a dedicated converter.
Recomendado
Small Motor and Actuator Controller
The PIC24F08KM202-I/SS can control small motors, valves, and actuators where the design needs fast timing and analog feedback within a limited memory budget. Its 32 MHz execution speed supports PWM generation, position or speed calculations, and real-time current monitoring through the ADC. The integrated DAC may generate a bias or reference level, while the operational amplifiers assist with feedback conditioning. Designers must verify the required PWM resolution, capture channels, comparator resources, and external driver requirements in the manufacturer documentation before committing the peripheral assignment.

Notas de diseño
Route analog inputs away from switching nodes, PWM outputs, and high-current return paths. Place the device's supply bypass capacitors immediately beside the corresponding power and ground pins, and keep the analog ground connection strategy consistent with the ground-reference arrangement shown in the manufacturer diagrams. The integrated amplifiers shorten sensitive traces, but poor grounding can still negate their benefit.
Use the manufacturer-recommended decoupling and bulk-capacitance values for the selected operating voltage. Because the device supports 1.8 V to 5.5 V operation, verify that every external analog and digital peripheral shares a compatible voltage domain or has suitable level translation. Confirm peripheral current, analog-reference current, and total supply-current limits before calculating regulator capacity.
Do not treat every MCU pin as a dedicated analog input. The 12-bit ADC, 8-bit DAC, operational amplifiers, comparators, and digital peripherals commonly share pins through multiplexing. Assign nets from the manufacturer pin-description table and account for the analog-peripheral configuration that disables the corresponding digital function. Also budget firmware size carefully because 8 KB of Flash limits protocol and application complexity.
For ADC-based measurements, sample at a rate consistent with the converter's acquisition requirements and allow the source impedance to discharge the sampling capacitor between conversions. Place precision analog components close to the relevant pins, use short traces, and avoid routing sensitive inputs beside the DAC output when both operate simultaneously. Calibrate offset and gain in firmware when the application requires accurate field measurements.
