PIC16F15224-I/P - 8-bit MCU 7KB Flash 32MHz 14-PDIP | Microchip
MPN: PIC16F15224-I/P ✓ פעילPIC16F15224-I/P סקירה
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, volatile data RAM, and a peripheral set (timers, ADC, communication, GPIO) into one package. The PIC16F152xx family is positioned as an Enhanced Mid-Range device within Microchip's PIC16 portfolio (PIC16 -> 8-bit MCU -> MCU -> semiconductor), pairing the standard PIC16 instruction set with Core Independent Peripherals (CIPs) and Intelligent Analog peripherals. Compared with the older baseline PIC16, the Enhanced Mid-Range core adds more instructions, deeper stack, and improved interrupt handling while maintaining code compatibility with classic PIC16F mid-range code where appropriate.
Key features include 12 I/O pins, a 10-bit ADC, two PWM modules, two CCP modules, hardware limit timer (HLT), watchdog timer (WDT), Peripheral Pin Select (PPS) for flexible signal routing, EUSART, MSSP (SPI/I2C), and eXtreme Low-Power (XLP) Sleep mode. The device operates from 1.8 V to 5.5 V with self-read/write Flash that supports in-application firmware updates. CIPs such as the configurable logic cell and signal measurement timer reduce CPU overhead, allowing the MCU to handle sensor interfacing, motor timing, and communication deterministically without software intervention.
Typical applications include cost-sensitive sensor nodes, home appliances, lighting control, battery-powered IoT endpoints, and low-end motor control. The wide 1.8 V to 5.5 V supply range and XLP Sleep current make it suitable for energy-harvesting and battery-backed designs. PPS allows designers to remap peripherals to any I/O pin, simplifying PCB routing and enabling PCB layout reuse across family variants in 8-pin SOIC, 14-pin PDIP/SOIC, and 20-pin packages.
A key design tip is to keep VDD decoupling within 5 mm of the supply pins and tie all unused pins to defined logic levels (VSS or VDD) to minimize I/O leakage. PPS remapping should be locked early in firmware to avoid unintended peripheral shifts at runtime.

יישומים טיפוסיים
PIC16F15224-I/P מתאים עבור 6 יישוםs: Battery-Powered Sensor Node, Home Appliance Control Board, LED Lighting Driver Controller, Small Motor Control (Fans, Pumps), Industrial Sensor Transmitter, Hobbyist / Educational Prototyping.
Battery-Powered Sensor Node
The PIC16F15224-I/P suits battery-powered sensor nodes because of its 1.8 V to 5.5 V supply range and XLP Sleep current below 1 uA. The Enhanced Mid-Range core runs the duty-cycled wake-measure-sleep firmware pattern, while the 10-bit ADC reads thermistor or analog sensor outputs. With 7 KB Flash and 512 bytes SRAM, the part comfortably fits a small RTOS loop, calibration tables, and OTA bootloader. PPS lets the designer remap UART, I2C, and ADC channels to any I/O, simplifying board layout versus fixed-pinout MCUs.
מומלץ
Home Appliance Control Board
The PIC16F15224-I/P drives home appliance control boards such as washing machines, dishwashers, and microwave user interfaces. Two PWM channels and two CCP modules handle motor speed, buzzer, and triac-fired heater timing; the EUSART interfaces with main board or HMI. CIPs such as the hardware limit timer (HLT) and configurable logic cell (CLC) handle safety interlocks and timing without CPU overhead. 7 KB Flash is enough for state machines plus diagnostics, and the 14-pin PDIP simplifies hand-soldered prototypes and through-hole production runs.
מומלץ
LED Lighting Driver Controller
The PIC16F15224-I/P drives LED lighting controllers in commercial and architectural luminaires. The two PWM outputs generate dimming waveforms down to sub-1% duty cycle for high-resolution dimming, and the MSSP (I2C) talks to constant-current LED driver ICs for thermal feedback and color mixing. XLP Sleep mode drops the idle current below 1 uA when the luminaire is off, meeting Energy Star standby targets. With 12 I/O exposed and PPS, RGBW channels can be remapped around PCB constraints without board respins.
מומלץ
Small Motor Control (Fans, Pumps)
The PIC16F15224-I/P is appropriate for small brushed DC motor or low-frequency BLDC commutation in fans, pumps, and small appliances. Two CCP modules and two PWM outputs drive H-bridge or 3-phase FET drivers, while the 32 MHz core executes commutation and PID loops in real time. The 10-bit ADC reads back-EMF or shunt current for closed-loop control, and the HLT peripheral enforces hardware-level PWM limits to protect the FETs during fault events. 14-pin PDIP is convenient for through-hole motor boards.
מומלץ
Industrial Sensor Transmitter
The PIC16F15224-I/P builds 4-20 mA loop-powered or 24 V industrial sensor transmitters with on-board signal conditioning. The 10-bit ADC reads bridge sensors (pressure, strain) or 4-20 mA loop inputs; the EUSART drives RS-485 or RS-232 industrial networks via a transceiver. Functional Safety (FuSa) family documentation supports IEC 61508 SIL-2 designs when the application requires it. Industrial -40C to +85C temperature range, plus PPS, lets the same PCB serve multiple SKUs with different I/O maps.
מומלץ
Hobbyist / Educational Prototyping
The PIC16F15224-I/P is well suited to hobbyist and educational prototyping through-hole designs because the 14-pin PDIP is breadboard-friendly. MPLAB X IDE and XC8 compiler are free, and the PICkit 4 programmer/debugger plugs directly into the ICSP pins. 7 KB Flash is plenty for teaching ADC, PWM, I2C, and UART basics; PPS lets students reassign peripherals without rewiring the breadboard. The same die in SOIC-14 (PIC16F15224-I/SL) lets projects migrate to surface-mount as designs mature.

הערות תכנון
Place a 100 nF decoupling capacitor within 5 mm of the VDD pin (pin 1) and a bulk 10 uF on the supply rail. For battery-powered designs, leverage XLP Sleep mode to drop quiescent current below 1 uA; configure all unused peripherals off in firmware before entering Sleep. Wake sources should be limited to WDT, IOC, or external interrupt to avoid false wakes.
MCLR/RA3 (pin 4) requires a 10 kohm pull-up to VDD for normal operation; if unused as reset, it can be configured as digital I/O. Avoid routing analog ADC signals near high-current PWM outputs to prevent coupling; the 10-bit ADC benefits from short traces to the analog source and a dedicated AVSS path. Use PPS to remap UART and I2C to pins away from PWM channels.
All unused I/O pins must be configured as outputs low (or inputs with internal weak pull-up enabled) - floating inputs cause excess Icc leakage and can trigger IOC events. Do not exceed 5.5 V on any pin including MCLR; transient suppression (TVS) is recommended for industrial boards. In-application programming (IAP) requires the upper Flash block to be write-protected correctly or new firmware may overwrite the running bootloader.
The MSSP I2C module benefits from external pull-ups on SCL/SDA (typically 4.7 kohm at 400 kHz, 3.3 kohm at 1 MHz); internal weak pull-ups are too weak for reliable multi-master buses. For SPI at high speeds, keep traces short and matched, and place a 33 ohm series resistor near the source pin to dampen reflections.
