PIC16F15224-I/MG Overview
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash), data memory (RAM), and integrated peripherals such as timers, ADCs, and communication interfaces. Within the broader taxonomy, the PIC16F15224 belongs to the 8-bit MCU category, then to the Enhanced Mid-Range Core family, then to Microchip's PIC16 product line, and finally to the power management and embedded control semiconductor hierarchy. The "I" suffix denotes industrial temperature range and the "MG" suffix denotes the 16-pin QFN package.
Key features include 7KB Flash program memory with self read/write capability, 512 bytes of SRAM, a 10-bit ADC, two PWM modules, two CCP (Capture/Compare/PWM) modules, hardware limit timer (HLT), windowed watchdog timer (WDT), peripheral pin select (PPS), EUSART, and MSSP supporting both SPI and I2C communication. The device leverages eXtreme Low Power (XLP) technology with a SLEEP mode that makes it suitable for battery-powered applications. According to the manufacturer datasheet, the Enhanced Mid-Range core executes 49 instructions across 16 stack levels.
Architecturally, the PIC16F15224 uses Microchip's Enhanced Mid-Range 8-bit RISC core which delivers deterministic interrupt response and single-cycle instruction execution (excluding branches). The integrated 10-bit ADC and Core Independent Peripherals (CIPs) allow hardware-based signal conditioning and timing without CPU intervention, reducing firmware complexity and power consumption. Peripheral Pin Select (PPS) provides flexible pin function remapping that simplifies PCB routing.
Typical applications include IoT sensor nodes, consumer electronics, low-power battery-operated devices, industrial control, LED lighting control, and small home appliances. The compact 3x3 mm QFN-16 footprint enables integration in space-constrained designs while the wide operating voltage range supports both 3.3V and 5V systems.
When designing with this device, ensure that programming pins (ICSPDAT/ICSPCLK) are accessible for in-circuit serial programming and debugging. The PPS feature requires configuration of register bits to remap peripheral functions; consult the device datasheet for valid input/output mapping combinations.

Typical Applications
PIC16F15224-I/MG is suitable for 6 applications: Battery-Powered IoT Sensor Nodes, Consumer Electronics Remote Controls, LED Lighting Control, Industrial Control Modules, Small Home Appliances, Automotive Interior Accessories.
Battery-Powered IoT Sensor Nodes
The PIC16F15224-I/MG is well suited for battery-powered IoT sensor nodes thanks to its eXtreme Low Power (XLP) technology with dedicated SLEEP mode drawing nanoamp-level quiescent current. The 10-bit ADC samples environmental sensors (temperature, humidity, motion) while the EUSART and MSSP peripherals communicate with radios such as LoRa or BLE modules. The 7KB Flash accommodates over-the-air update bootloaders and protocol stacks. With the 16-QFN (3x3 mm) footprint, the MCU fits inside compact sensor enclosures. Peripheral Pin Select (PPS) allows flexible PCB routing of ADC channels and serial interfaces to match sensor placement. Estimated battery life with periodic wake-up cycles can exceed 5 years on a CR2032 coin cell.
Recommended
Consumer Electronics Remote Controls
The PIC16F15224-I/MG is ideal for consumer remote controls due to its low-power SLEEP mode that extends battery life across years of standby. The two PWM modules drive IR LED transmitters for multi-protocol remote signaling, while the EUSART interfaces with optional RF transceivers. The Hardware Limit Timer (HLT) offloads button-debounce and timeout logic from firmware, reducing code size. With only 16 pins in a 3x3 mm QFN, the design fits inside slim remote-control enclosures. The PIC16F15224's 32MHz CPU delivers fast response for consumer-grade button-press latency under 20 ms.
Recommended
LED Lighting Control
The PIC16F15224-I/MG controls constant-current LED drivers via its two PWM outputs, enabling smooth dimming from 0 to 100 percent without flicker. The 10-bit ADC reads ambient light sensors or potentiometer inputs for closed-loop brightness control, while the EUSART supports DMX-512 or DALI communication interfaces. With 7KB Flash, firmware can implement color-mixing algorithms for RGBW fixtures and temperature fold-back protection. The 16-QFN package's exposed thermal pad supports thermal dissipation when the MCU coexists with LED driver MOSFETs on the same PCB.
Recommended
Industrial Control Modules
The PIC16F15224-I/MG operates over the industrial -40C to +85C temperature range required for factory-floor modules. The Core Independent Peripherals (CIPs) such as the Hardware Limit Timer handle encoder counting, pulse measurement, and motor control without CPU load. The EUSART and MSSP connect to RS-485 transceivers and I2C sensors respectively, while the 10-bit ADC monitors analog process variables. The Functional Safety (FuSa) features enable use in safety-related industrial subsystems. With PPS, the same PCB layout can route signals to different MCU pins to accommodate design variations across product variants.
Recommended
Small Home Appliances
The PIC16F15224-I/MG fits small home appliances such as coffee makers, blenders, and fans where compact 16-pin QFN packages reduce BOM cost. Two PWM channels drive motor speed control or heating element regulation while the 10-bit ADC reads NTC thermistors for closed-loop temperature control. The MSSP interfaces with I2C displays or keypads for user feedback, and the EUSART supports optional WiFi or BLE module connectivity. The XLP SLEEP mode reduces standby power below regulatory thresholds for energy-star appliances.
Recommended
Automotive Interior Accessories
The PIC16F15224-I/MG serves automotive interior accessories such as ambient lighting controllers, seat heaters, and USB charging indicators. The PIC16F15224 operates across the full industrial -40C to +85C range, suitable for cabin environments. Two PWM outputs drive LED strings or heating-element MOSFETs with hardware-limited duty cycle. The MSSP communicates with I2C ambient-light sensors and the EUSART interfaces with body-control modules for status reporting. Note that automotive safety-critical applications require AEC-Q100 qualified parts; the standard PIC16F15224-I/MG is industrial-grade and not AEC-Q100 qualified.

Key Differentiators
- Higher Flash density than PIC16F15223 within the same package (vs PIC16F15223-I/MG)
- Peripheral Pin Select (PPS) provides flexible pin function remapping (vs PIC16F1614-I/ML)
- XLP SLEEP mode reduces standby power below nanoWatt levels (vs PIC16F1614-I/ML)
Design Notes
The PIC16F15224-I/MG's XLP SLEEP mode draws nanoamp-level quiescent current, but only when peripherals are properly gated before the SLEEP instruction. Estimated: with ADC disabled, WDT off, and all I/O set to inputs with no pull-ups, SLEEP current falls below 100 nA. Always configure the VREGPM bit and disable unused peripherals in firmware to achieve datasheet low-power figures. For battery-life calculations, include active-mode current at the operating clock frequency plus wake-up event frequency.
The 16-QFN (3x3 mm) package has an exposed thermal pad on the underside that must be soldered to a ground plane for mechanical reliability and thermal dissipation. Per the manufacturer datasheet, the QFN pad should have multiple thermal vias connecting it to internal ground layers for optimal heat spreading. Place decoupling capacitors (100 nF ceramic plus 10 uF bulk) within 3 mm of the VDD pin. For PPS-routed signals, keep traces short and avoid running them parallel to switching converter or motor-drive traces.
A common design pitfall is leaving the ICSPDAT/ICSPCLK pins (RB6/RB7) configured as outputs after programming, which prevents in-circuit debugging. Per the datasheet, configure RB6 and RB7 as high-impedance inputs in firmware initialization. Also, the PPS feature requires explicit register writes before peripheral functions are routed to alternate pins - failure to configure PPS results in peripherals appearing non-functional. Always verify the configuration bits and PPS assignments at production test.
Compliance Information
RoHS and REACH compliant per Microchip product page. The PIC16F15224-I/MG is industrial-grade and not AEC-Q100 qualified; automotive applications should select AEC-Q100 qualified variants.
