PIC16F15244T-I/SO Overview
An 8-bit microcontroller (MCU) is a small, low-cost, single-chip computer that integrates a CPU, program memory (Flash), data RAM, and peripherals such as ADC, timers, and communication interfaces. MCUs sit in the embedded-system hierarchy above sensors and below system-on-modules, executing firmware that reads inputs, processes logic, and drives outputs. The PIC16F152xx family specifically targets cost-sensitive sensor and real-time control applications with a streamlined CIP (Core Independent Peripheral) set and eXtreme Low-Power (XLP) Sleep modes for battery-powered designs.
Key features of the PIC16F15244T-I/SO include a 32 MHz internal oscillator, 10-bit ADC with up to 12 channels, two PWM modules, two CCP (Capture/Compare/PWM) modules, hardware Limit Timer (HLT), Watchdog Timer (WDT), Peripheral Pin Select (PPS), EUSART, and SPI/I2C interfaces. The XLP Sleep Mode reduces quiescent current for battery applications, and Memory Access Partition (MAP) supports bootloader and FuSa-grade isolation between non-secure and secure firmware regions.
The device uses Microchip's enhanced mid-range 8-bit core with a 14-bit instruction word, providing deterministic interrupt latency and a single-cycle instruction execution at 32 MHz. PPS allows digital peripheral pin reassignment, which simplifies PCB layout and reduces design rework. Functional Safety features make the part suitable for safety-critical appliance, industrial sensor, and home-automation designs targeting IEC 60730 Class B.
Typical applications include consumer appliance control, IoT sensor nodes, battery-powered instrumentation, LED lighting controllers, and small motor/valve control loops. The wide 1.8V-5.5V operating range and integrated analog make the part drop-in friendly for portable, mains-bucked, and rechargeable-battery designs.
When designing with this device, place decoupling capacitors within 2 mm of VDD/AVDD pins, avoid driving ADC inputs with high-impedance sources without a buffer, and verify unused I/O pin configuration (input or output, never floating) to minimize Sleep-mode current draw. Use PPS only on digital peripherals to maintain ADC reference integrity.

Typical Applications
PIC16F15244T-I/SO is suitable for 6 applications: Consumer Appliance Control, IoT Battery-Powered Sensor Node, LED Lighting Controller, Industrial Sensor Interface, Home Automation and Security, Small Motor and Valve Control.
Consumer Appliance Control
The PIC16F15244T-I/SO's 7 KB Flash, Functional Safety (FuSa) support, and Memory Access Partition (MAP) make it a strong fit for IEC 60730 Class B compliant consumer appliances such as washing machines, dishwashers, and induction cooktops. The MAP feature isolates safety firmware from main application code, simplifying certification for white-goods designs. The 32 MHz core is fast enough to run a sensor-fusion state machine plus a user-interface tasking loop. Two CCP modules and 10-bit ADC read thermistors, pressure sensors, and zero-cross detectors directly without external analog front-end. The wide 1.8V-5.5V supply range simplifies designs that need to survive brownouts or operate from a half-wave rectified mains bus.
Recommended
IoT Battery-Powered Sensor Node
The PIC16F15244T-I/SO is well suited for wireless sensor nodes and battery-powered IoT endpoints because of its eXtreme Low-Power (XLP) Sleep Mode and the 32 MHz HFINTOSC that lets the radio packet processing finish quickly before re-entering Sleep. The 7 KB Flash is large enough to host a Bluetooth Low Energy stack fragment or LoRaWAN application layer, and 512 B RAM holds sensor sample buffers between transmit events. PPS routes the EUSART or SPI directly to the radio module's pins without requiring a remap board. Sleep current in the nanoampere range (typical 50 nA with WDT disabled) lets a CR2032-powered node run for years. The 10-bit ADC is sufficient for thermistor, humidity, and battery-voltage monitoring.
Recommended
LED Lighting Controller
For LED drivers and lighting-control applications, the PIC16F15244T-I/SO provides two hardware PWM channels and two CCP modules, enough to drive RGBW LEDs with smooth 16-bit PWM at frequencies above the flicker-fusion threshold. The 32 MHz core can refresh a 4-channel LED panel at 1 kHz with minimal CPU overhead. The 10-bit ADC reads ambient light sensors and current-sense amplifiers for closed-loop constant-current regulation. Peripheral Pin Select routes the PWMs to any GPIO, simplifying PCB routing of multi-string LED boards. The wide supply range (1.8V-5.5V) lets the MCU share the LED driver's 5V rail or a 3.3V buck output without an extra regulator.
Recommended
Industrial Sensor Interface
In industrial sensor and transducer applications, the PIC16F15244T-I/SO's 10-bit ADC, PPS, and EUSART deliver flexible analog and serial front-end design. The FuSa-ready architecture supports redundant sensor diagnostics required by IEC 61508 SIL-2 capable systems when paired with the Microchip Class B library. Two PWM modules drive proportional valves or 4-20 mA loops without an external DAC. The 32 MHz core can run a 100 ms control loop while servicing SPI peripherals. The -40 C to +85 C industrial temperature grade handles factory-floor environments, and 256 B EEPROM stores calibration coefficients without wear from daily reset events.
Recommended
Home Automation and Security
The PIC16F15244T-I/SO fits compact home-automation hubs and security keypads thanks to its PPS flexibility, integrated EUSART + SPI + I2C interfaces, and 7 KB Flash for a small Z-Wave, Zigbee, or proprietary RF stack fragment. The MAP feature isolates the secure-element firmware for credential handling from the application logic, supporting Matter-ready and SESIP-style security profiles. Two CCP modules drive a buzzer and LED indicators without external timer ICs. The 10-bit ADC reads tamper switches and battery voltage with hardware averaging. The XLP Sleep mode supports multi-year battery life on wireless door/window sensors and PIR motion detectors.
Recommended
Small Motor and Valve Control
The PIC16F15244T-I/SO is suitable for brushed-DC motor, stepper, and solenoid-valve control thanks to two hardware PWM outputs (one 16-bit, one 10-bit) plus two CCP modules. The 32 MHz core executes field-oriented control loops or trapezoidal commutation at 20 kHz with headroom for current sensing and fault handling. The 10-bit ADC reads back-EMF, current-sense resistors, and temperature sensors at sufficient resolution for closed-loop control. Hardware Limit Timer (HLT) generates a hardware safety timeout independent of firmware, supporting functional-safety requirements. PPS routes the PWM outputs to any GPIO for flexible half-bridge or full-bridge PCB layouts.

- Higher Flash and RAM than 15243 family (vs PIC16F15243-I/SO)
- Lower-cost vs 12-bit ADC sibling (vs PIC16F15245-I/SO)
- eXtreme Low-Power (XLP) Sleep Mode for battery designs (vs PIC16F15224-I/SO)
Design Notes
Place a 100 nF decoupling capacitor within 2 mm of each VDD pin, plus a bulk 1-10 uF capacitor on the main supply rail. For ADC accuracy, tie AVSS directly to VSS at a single point and add a 100 nF + 10 uF pair on AVDD if the part exposes it. Sleep-mode current is in the nanoampere range with WDT disabled - ensure no floating inputs by configuring unused I/O pins as outputs low or inputs with internal pull-ups.
Use Peripheral Pin Select (PPS) to route EUSART, SPI, and I2C pins to convenient GPIO locations, simplifying PCB routing. Avoid routing high-frequency digital signals next to analog input pins to minimize ADC coupling. Keep the 32 MHz HFINTOSC trace short and provide a ground ring around the crystal or resonator if used. Place configuration jumpers near the IC for ICD and In-Circuit Serial Programming (ICSP) access.
Do not assume the analog input pins (ANx) are 5V-tolerant when VDD is below 5V - consult the Absolute Maximum Ratings table. The PPS feature applies only to digital peripherals; analog pin assignments are fixed. When migrating firmware from PIC16F1825 or PIC16F151x, verify register-map compatibility because MAP-protected code regions are new in PIC16F152xx. Do not exceed 32 MHz CPU clock or the device will behave out of spec; HFINTOSC tuning has +/- 2% accuracy over temperature.
Estimated: at VDD=3.3V, CPU active at 32 MHz, IOUT=10 mA, total power dissipation is approximately 33 mW. With a SOIC-20 theta_JA of approximately 80 C/W, the junction rises about 2.6 C above ambient - well below the 150 C thermal shutdown. At VDD=5.5V and active CPU, dissipation rises to ~55 mW (~4.4 C rise). No external heatsink is required for any normal operating condition of this part.
