PIC16F15224-E/MG Overview
A microcontroller (MCU) is a single-chip computer containing a CPU, memory, and programmable I/O peripherals on one integrated circuit. The PIC16F152xx family sits within the 8-bit microcontroller hierarchy: PIC16F -> 8-bit PIC -> PIC microcontroller -> microcontroller -> embedded IC -> semiconductor. MCUs power billions of devices across consumer, industrial, and automotive markets because they combine deterministic real-time control, low power, and small footprint at low cost.
Key features of the PIC16F15224-E/MG include a 10-bit ADC, two PWM channels, two Capture/Compare/PWM (CCP) modules, an EUSART, an MSSP (SPI/I2C), hardware limit timer (HLT), watchdog timer (WDT), and eXtreme Low-Power (XLP) SLEEP mode. The Functional Safety (FuSa) variant designation indicates readiness for safety-critical applications including IEC 61508 SIL-capable designs. Operating voltage range is 1.8 V to 5.5 V across -40 °C to +125 °C.
The Enhanced Mid-Range architecture uses a 14-bit instruction word with hardware multiplier and 16-level deep hardware stack. Peripheral Pin Select (PPS) remaps most digital peripheral signals onto a wide range of I/O pins, simplifying PCB layout when peripherals must be repositioned. The XLP technology typically achieves nanoampere SLEEP currents with brown-out reset (BOR) and power-on reset (POR) supporting battery-powered designs.
Typical applications include low-power IoT sensor nodes, home appliances, HVAC controls, LED lighting controllers, battery chargers, automotive body and lighting modules, and small motor control loops. The 16-QFN (3x3) package suits space-constrained wearables and compact industrial sensor modules.
When designing with this part, ensure programming/debug access is provisioned via PGD/PGC pins (not present in the 16-QFN variant's minimal pinout, so consider ICSP header pads). Select the proper VDD range (1.8 V - 3.6 V or 2.3 V - 5.5 V) before configuring the ADC for full 10-bit accuracy.

Typical Applications
PIC16F15224-E/MG is suitable for 6 applications: Battery-Powered IoT Sensor Node, Home Appliance Control Board, Automotive Body & Lighting Module, LED Lighting Controller, HVAC Fan & Damper Control, Small Appliance & Wearable Device.
Battery-Powered IoT Sensor Node
The PIC16F15224-E/MG's eXtreme Low-Power (XLP) SLEEP mode (nanoampere-level Iq) and 1.8 V minimum VDD make it ideal for wireless sensor nodes running on coin-cell or 2xAA batteries. The 32 MHz core wakes periodically to read sensors via the 10-bit ADC and transmits via EUSART or MSSP-I2C. The integrated WDT and HLT ensure deterministic wake intervals without external RTC.
Recommended
Home Appliance Control Board
Washing machines, dishwashers, and microwave ovens use PIC16F15224-E/MG for motor control, user-interface scanning, and timing. The 2 PWM channels drive triac-based heater control; 2 CCP modules handle brushless-DC motor commutation; and the EUSART interfaces to the HMI display. Industrial -40 to +125 °C temperature range supports unventilated enclosures near heating elements.
Recommended
Automotive Body & Lighting Module
The PIC16F15224-E/MG operates over the full automotive -40 to +125 °C range required for under-hood and cabin body controllers. PPS allows routing EUSART (LIN), MSSP (SPI to LED drivers), and PWM channels to any available pin, simplifying PCB layout. The Functional Safety (FuSa) designation provides documentation support for ISO 26262 ASIL-aware designs at lower ASIL levels.
Recommended
LED Lighting Controller
Tunable-white and RGB LED fixtures use PIC16F15224-E/MG's 2 PWM channels plus 2 CCP modules to drive up to 4 independent LED strings with 10-bit dimming resolution. The 32 MHz core performs color-mixing algorithms while EUSART/MSSP connect to DMX-512 or DALI interfaces via external transceivers. XLP sleep mode reduces standby power below 1 µA for ENERGY STAR compliance.
Recommended
HVAC Fan & Damper Control
Variable-speed fans and motorized dampers in HVAC systems use PIC16F15224-E/MG to read temperature/humidity sensors, compute PID control, and drive brushless DC fans via PWM or CCP. The integrated 10-bit ADC handles multiple analog inputs; the HLT peripheral provides hardware limit protection without CPU intervention; and the WDT recovers from software faults.
Recommended
Small Appliance & Wearable Device
Compact 3x3 mm 16-QFN footprint fits toothbrushes, fitness bands, and wearable health monitors where board area is precious. PIC16F15224-E/MG's XLP technology extends battery life to months on a single coin cell, while the 32 MHz core handles BLE pairing stacks via SPI to an external radio. PPS simplifies routing the SPI/I2C buses between the radio, display, and sensor cluster.

Key Differentiators
- Extended -40 to +125 °C automotive temperature range (E grade) (vs PIC16F15224-I/MG)
- Functional Safety (FuSa) documentation support (vs PIC16F15223-I/MG)
- Balanced Flash-to-SRAM ratio for mid-size firmware (vs PIC16F15225-I/MG)
Design Notes
Estimated: At 32 MHz, VDD=3.3 V, and typical active core current ~3 mA, total current draw reaches ~7-10 mA when peripherals are active. In SLEEP mode with XLP enabled, quiescent current falls below 1 µA. For battery-powered designs, use the HLT peripheral for periodic wake rather than a software loop to minimize average current.
The 16-QFN (3x3) exposed thermal pad MUST be soldered to the ground plane for proper thermal dissipation and electrical performance. Use an array of thermal vias (typically 5-9 vias, 0.3 mm drill) connecting the pad to inner ground layers. Inadequate soldering can cause intermittent failures and thermal shutdown.
Do not assume the 16-QFN package includes dedicated PGD/PGC programming pins - the PIC16F15224-E/MG shares these with general-purpose I/O via PPS. Plan PCB layout to allow ICSP access (header pads or test points) for production programming. Failure to provide programming access is a common board respin trigger.
Place the 0.1 µF VDD bypass capacitor within 5 mm of the VDD pin with a short trace to the ground pad. Add a bulk 1-10 µF capacitor near the MCU for transient load support. Keep the crystal/oscillator traces short and symmetric, surrounded by ground pour to minimize EMI and ensure stable clock operation.
Compliance Information
RoHS compliant per Microchip product page. The -E temperature grade extends to +125 °C, but the part is not formally AEC-Q100 qualified - consult Microchip's automotive-grade MCU portfolio for AEC-Q100 listed devices. Functional Safety (FuSa) documentation is available separately from Microchip.
