PIC18F24Q10-I/SO Présentation
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data-path CPU, on-chip program memory, RAM, EEPROM, and a rich set of peripherals. PIC18 MCUs use a modified Harvard RISC architecture that executes one instruction per clock cycle (except branches) and are widely deployed in real-time control and sensor-interface products. The PIC18-Q10 sub-family extends the PIC18 line with integrated intelligent analog, configurable peripherals and 5V operation for increased noise immunity in industrial environments. The hierarchy is: 8-bit MCU -> microcontroller -> embedded processor -> semiconductor IC.
Key features of the PIC18F24Q10 include 25 programmable I/O pins, a 10-bit ADC with up to 24 channels, a 5-bit DAC, two comparators, a 16-bit PWM, a Capture/Compare/PWM (CCP) module, a Windowed Watchdog Timer (WWDT), Core Independent Peripherals (CIPs) such as Configurable Logic Cells (LCs/CLCs), and an internal oscillator. The 1.8V to 5.5V supply range supports both 3.3V and 5V rails commonly found in industrial and consumer designs. XLP technology delivers nanoWatt sleep currents, enabling long battery life.
The 28-SOIC package provides a 0.3-inch wide, surface-mount footprint compatible with hand-soldering and standard reflow profiles, with 25 user I/O pins broken out on the 28-pin SOIC. The functional-safety (FuSa) classification allows designers to use the part in systems that require IEC 61508 or ISO 26262 documentation support.
Typical applications include sensor nodes, IoT edge devices, home appliances, LED lighting controllers, low-power battery-powered instruments, and small industrial-control loops where 5V noise immunity and core-independent peripherals reduce firmware complexity. Engineers use the CCP and 16-bit PWM modules for motor or LED control and the CLCs to implement glue logic without external gates.
When designing, select the appropriate ICSP programming header and reserve the RA0/RA1 pins if using the 5-bit DAC; ensure decoupling capacitors are placed within 5 mm of VDD/VSS. For battery applications, verify the nanoWatt sleep mode wake-up source and configure the WWDT before locking the configuration bits.

Applications typiques
PIC18F24Q10-I/SO convient pour 7 applications: Industrial Sensor Nodes, Home Appliance Control (White Goods), Battery-Powered IoT Edge Devices, LED Lighting Controllers, Touch-Sensing User Interfaces, Automotive Body Electronics (Non-Safety), Small Industrial-Control Loops (PLCs / PID).
Industrial Sensor Nodes
The PIC18F24Q10-I/SO is a strong fit for industrial sensor nodes where 5V noise immunity and CIP-based signal conditioning matter. Its 10-bit ADC with up to 24 channels (per Microchip datasheet DS40001979D) can sample multiple analog sensors - temperature, pressure, flow - without external muxes. The Configurable Logic Cells (CLCs) glue analog compare events to PWM outputs autonomously, so the CPU stays in XLP nanoWatt sleep until a wakeup event occurs. At 64 MHz the CPU still has headroom for FFT or filtering on bursts of data.
Recommandé
Home Appliance Control (White Goods)
White-goods designs - washing machines, dishwashers, induction cookers - need 16-bit PWM plus CCP for motor and H-bridge control, plus robust 5V operation. The PIC18F24Q10-I/SO delivers both at 64 MHz / 16 MIPS, drives triac-fired loads via its CCP, and benefits from the Functional Safety (FuSa) classification which shortens IEC 60335-1 / IEC 60730 safety documentation. Its industrial -40 to +85 C range covers behind-panel thermal rise in appliances.
Recommandé
Battery-Powered IoT Edge Devices
Battery-powered IoT endpoints - BLE beacons, environmental loggers, smart locks - rely on the PIC18F24Q10-I/SO's XLP nanoWatt sleep currents and CIP-driven wake logic. With 16 KB Flash, 1 KB SRAM and the 5-bit DAC for sensor excitation, the MCU can run an entire edge node from a CR2032 cell for years. The Windowed WDT (WWDT) lets firmware enforce strict servicing windows, mandatory for safety-critical battery cut-off paths in locks.
Recommandé
LED Lighting Controllers
LED drivers and color-mixing controllers benefit from the PIC18F24Q10-I/SO's 16-bit PWM plus CCP for smooth dimming and per-channel current control. The 16-bit PWM gives 65,536 steps - sub-1 % dimming without flicker to the human eye at low duty cycles - while the 10-bit ADC monitors LED current and temperature. The CLCs can implement zero-cross detection for triac dimmers without burning CPU cycles.
Recommandé
Touch-Sensing User Interfaces
The PIC18-Q10 family integrates Microchip's mTouch peripheral, and the PIC18F24Q10-I/SO can serve as the master controller for capacitive touch sliders, buttons, and proximity sensors. The CIP-based hardware touch decoder handles scanning autonomously, freeing the core to run UI state machines. With up to 24 ADC channels and 25 I/O pins the device supports medium-density keypads and small TFTs over SPI.
Recommandé
Automotive Body Electronics (Non-Safety)
The PIC18F24Q10-I/SO is well suited to non-safety automotive body modules - seat controllers, mirror adjusters, HVAC blend-door drivers - thanks to its 1.8-5.5 V supply range, 64 MHz performance, and functional-safety (FuSa) documentation support that simplifies AEC-Q100 and ISO 26262 paperwork. Select the PIC18F24Q10-E/SO variant (extended -40 to +125 C) for under-hood thermal exposure. Its LIN-friendly EUSART and CCP/PWM simplify actuator driving.
Recommandé
Small Industrial-Control Loops (PLCs / PID)
PID loops for temperature, flow and pressure control in compact PLCs and process transmitters run comfortably on the PIC18F24Q10-I/SO. The 16 MIPS gives 16-bit instructions per clock, with hardware PWM, 10-bit ADC and 5-bit DAC forming a complete analog front-end. The CLCs can implement direction-of-rotation or fail-safe interlocks without external gates, reducing BOM cost in space-constrained DIN-rail modules.

Notes de conception
Place a 100 nF ceramic decoupling capacitor within 5 mm of the VDD pin (pin 5) and a bulk 10 uF tantalum or ceramic at the supply entry. For designs that operate down to 1.8 V, ensure the regulator has a sub-50 mV droop on 50 mA transients; pair the PIC18F24Q10-I/SO with the MCP1700 LDO for battery rails. Activate the XLP nanoWatt sleep modes in firmware via the SLEEP instruction with peripheral disable bits set, otherwise residual ADC/CIP currents will dominate quiescent draw.
Keep the analog AVdd/AVss rails (shared with VDD/VSS on 28-SOIC) noise-free by isolating the 10-bit ADC inputs on a separate analog-ground island if the design mixes motor drivers or RF. Route the ICSP clock (RB6) and ICSP data (RB7) traces to a 6-pin header with 0.1-inch spacing and keep them short - long traces pick up programmer noise and fail bulk erase. For high-speed 64 MHz operation, surround the package with a continuous VSS guard ring on the top layer to suppress radiated emissions.
Beware of unconfigured I/O pins drawing parasitic current - always set unused RA/RB/RC pins as outputs driven low. The 5-bit DAC outputs share RA0/RA1, so firmware that repurposes these pins as ADCs must clear the DACEN bit first. Configuration bits must be programmed before locking, including WDT window and the MCLR pin function (RE3); otherwise the part will silently reset on power-up. Finally, do not exceed 5.5 V on any pin even in transient spikes - the ESD diodes clamp to VDD/VSS and can latch.
