PIC16F15244-I/SS Übersicht
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and peripheral interfaces on one die. PIC microcontrollers sit within the broader category of microcontrollers -> embedded microprocessors -> digital ICs -> integrated circuits, where 8-bit MCUs remain dominant in cost-optimized, deterministic control loops where power efficiency, interrupt latency, and small pin counts matter more than raw compute throughput. The PIC16F152xx family specifically targets applications requiring more on-chip intelligence than a basic GPIO expander while staying inside the 8-bit cost envelope.
Key features include Peripheral Pin Select (PPS) for flexible signal routing, a 10-bit ADC with computation, a 5-bit DAC, two comparators, an 8-bit timer (TMR0), 16-bit Timer1/3, an 8-bit TMR2 with periodic interrupt, a hardware Universal Asynchronous Receiver Transmitter (EUSART), and a Master Synchronous Serial Port supporting both SPI and I2C. The 20-pin SSOP package exposes 18 I/O pins after power and ground allocations. Core Independent Peripherals such as the Configurable Logic Cell (CLC) and Complementary Waveform Generator (CWG) enable complex timing, motor-control, and signal-conditioning tasks to run without CPU intervention.
Typical applications span appliance control, LED lighting drivers, sensor signal conditioning, automotive body electronics, consumer white goods, industrial IoT edge nodes, and small form-factor human-machine interface boards. The combination of XLP sleep currents, fast wake-up, and on-chip CIPs allows battery-powered designs to operate for years on a single cell.
When designing with this part, allocate 4 I/O for the In-Circuit Serial Programming (ICSP) interface (ICSPCLK/ICSPDAT plus VPP/MCLR) if you require field re-flash capability. Always decouple VDD with a 100nF ceramic placed within 5mm of the pin, and follow Microchip AN-383 "Microcontroller Board Design" PCB guidelines to keep ADC readings clean.

Typische Anwendungen
PIC16F15244-I/SS ist geeignet für 8 Anwendungs: Battery-Powered IoT Sensor Node, Appliance and White Goods Control, Automotive Body Electronics, LED Lighting and Dimming Controllers, Industrial Sensor Signal Conditioning, Consumer Remote Controls and HMI, Small Form-Factor Power Supply Monitoring, Educational and Prototyping Platforms.
Battery-Powered IoT Sensor Node
The PIC16F15244-I/SS fits battery-powered IoT sensor nodes because it combines eXtreme Low-Power (XLP) sleep currents below 1uA with fast wake-up from the on-chip RTC or interrupt-on-change (IOC) and on-chip 10-bit ADC with computation. Designers can sleep the part between sensor reads, wake on a timer interrupt, capture an ADC sample with hardware averaging, and return to sleep within hundreds of microseconds. This pattern, applied to temperature, humidity, or occupancy sensors, yields multi-year battery life on a single CR2032 cell.
Empfohlen
Appliance and White Goods Control
The PIC16F15244-I/SS serves as the main controller in appliance boards (washing machines, dishwashers, refrigerators) thanks to its IEC 60730 Class B Functional Safety features, on-chip comparators for line-voltage zero-cross detection, and CWG (Complementary Waveform Generator) for triac and IGBT drive. The 32MHz core handles user-interface button scanning, motor control loops, and UART communication to a Wi-Fi module simultaneously. Industrial temperature grade (-40C to +85C) ensures reliable operation in unheated enclosures.
Empfohlen
Automotive Body Electronics
The PIC16F15244-I/SS is suitable for automotive body-electronics modules such as lighting controllers, seat-position modules, and HVAC panel interfaces, where its industrial temperature range, on-chip PWM, and Enhanced UART (EUSART) handle LIN-bus-like communication. The wide 1.8V to 5.5V supply range tolerates cranking transients when paired with an external LDO. Designers leverage the CLC (Configurable Logic Cell) to implement custom signal conditioning in hardware, offloading the CPU and reducing firmware complexity.
Empfohlen
LED Lighting and Dimming Controllers
The PIC16F15244-I/SS is well matched to LED drivers and dimming controllers because its Complementary Waveform Generator (CWG) produces complementary PWM with programmable dead-band for high-side/low-side MOSFET drive, while the 10-bit ADC reads current-sense feedback for closed-loop constant-current regulation. Peripheral Pin Select routes the PWM channels to any digital I/O, simplifying PCB layout. The XLP sleep mode keeps standby power below 50uA to satisfy energy-star limits.
Empfohlen
Industrial Sensor Signal Conditioning
The PIC16F15244-I/SS performs analog front-end conditioning in industrial 4-20mA loop-powered transmitters, RTD/thermocouple interfaces, and bridge-sensor amplifiers. Its on-chip op-amp-free comparators implement window detection, while the 10-bit ADC with computation does oversampling and averaging in hardware, freeing the CPU for linearization math. The on-chip 5-bit DAC programs the excitation current for resistive sensors, reducing external BOM cost.
Empfohlen
Consumer Remote Controls and HMI
The PIC16F15244-I/SS drives consumer remote controls, thermostats, and small HMI boards by combining PWM-driven LED indicators, EUSART for IR or RF daughter modules, and interrupt-on-change wake-up for ultra-low-power button press detection. The SSOP-20 footprint is small enough for handheld enclosures but still large enough for hand-soldered prototypes. The internal 32MHz oscillator eliminates an external crystal, reducing BOM and assembly cost.
Empfohlen
Small Form-Factor Power Supply Monitoring
The PIC16F15244-I/SS functions as a digital supervisor in compact AC/DC and DC/DC power modules, monitoring output voltage through the ADC, asserting the EUSART for PMBus or UART telemetry, and using the comparators for over-current and over-temperature protection. Its 1.8V minimum supply lets it run from an auxiliary winding or external bias supply without needing a separate regulator. Hardware CIPs implement fault latching and recovery without CPU intervention.
Empfohlen
Educational and Prototyping Platforms
The PIC16F15244-I/SS is a strong fit for educational microcontroller courses, hobbyist prototyping boards, and maker-space projects because of Microchip's free MPLAB X IDE, XC8 compiler, and the rich PIC16F15244 code-examples library on GitHub. The 20-pin SSOP package is breadboard-friendly when paired with a SOIC-to-DIP adapter, and the In-Circuit Serial Programming (ICSP) interface enables field re-flash without removing the chip. The CIPs let students explore hardware-configurable logic alongside traditional firmware design.

Wichtigste Unterscheidungsmerkmale
- Core Independent Peripherals (CLC, CWG, NCO) reduce CPU load (vs. PIC16F1518-I/SS)

- 32MHz core with 49-instruction enhanced mid-range set (vs. PIC16F1509-I/SS)
Designhinweise
Place a 100nF X7R ceramic decoupling capacitor within 5mm of the VDD pin, and a 10uF bulk capacitor on the main supply rail. For battery-powered designs, use the PIC16F15244's Low-Power Sleep mode and configure the RTC or WDT to wake the part on a programmable interval. Verify the 32MHz HFINTOSC accuracy against your timing-critical UART baud-rate tolerance before relying on the internal oscillator.
Allocate dedicated traces for the ICSP interface (ICSPCLK on RB7 and ICSPDAT on RB6) so the device can be re-flashed in-circuit without removing the chip. Keep analog ADC traces short and routed away from digital switching lines; use a ground pour under the MCU and tie AGND to DGND at a single point. Follow Microchip AN-383 "Microcontroller Board Design" for canonical layout guidelines.
When routing the MSSP SPI bus at >4MHz, place 33 ohm series damping resistors at the driving pins to limit ringing. For I2C buses above 400kHz, calculate the pull-up resistor value to satisfy the rise-time specification: rise_time ≈ 0.85 * R * C_bus. Avoid running the SPI/I2C traces parallel to noisy switching traces for more than 25mm; cross at 90 degrees if necessary.
Do not leave the MCLR/VPP pin floating - tie it to VDD through a 10k resistor or directly drive it high to prevent spurious resets. Configure unused I/O pins as outputs low (not inputs) to minimize supply current. When using the ADC, allow the acquisition time (TACQ) to elapse before initiating the conversion; the 10-bit ADC's input capacitance and source impedance directly affect accuracy.
