PIC16F15344-I/GZ Overview
An 8-bit microcontroller (MCU) is a small computer-on-a-chip that integrates a CPU, program memory (Flash), data memory (RAM), and a rich set of peripheral interfaces onto a single silicon die. The "PIC" family from Microchip uses a Harvard-architecture RISC core that executes one instruction per clock cycle (excluding branches), offering deterministic behavior prized in real-time control. PIC16F153xx devices sit in the "Enhanced Mid-Range" tier with 49 instructions and 16 stack levels, providing a balance of code efficiency, peripheral integration, and cost-effectiveness for consumer, industrial, and IoT applications.
Key features of the PIC16F15344-I/GZ include 7KB self-read/write Flash, 512 bytes RAM, a 10-bit ADC with computation (ADC2), a 5-bit DAC, two comparators, a Complementary Waveform Generator (CWG), four 10-bit PWMs, and 2 EUSART plus SPI/I2C communication interfaces. The device also includes peripheral pin select (PPS) for flexible routing and multiple timer modules.
The PIC16F15344 uses Microchip's enhanced mid-range core with 49 instructions and 16 stack levels. The XLP architecture enables deep sleep currents in the nanoamp range with retention, making the device attractive for battery-powered sensor nodes where quiescent current dominates battery life. Hardware CIPs such as the CWG, configurable logic cells (CLC), and signal measurement timer (SMT) offload timing-critical tasks from the CPU, reducing code complexity and power consumption.
Typical applications include IoT sensor nodes, battery-powered wearables, home automation controllers, low-power wireless peripherals, consumer white goods, industrial sensor interfaces, and small motor-control subsystems where on-chip PWMs and comparators simplify the BOM. Its tiny 4x4 mm UQFN footprint suits space-constrained designs.
When designing with the PIC16F15344-I/GZ, ensure the UQFN-20 PCB footprint includes a sufficient central exposed pad for thermal dissipation and solder joint reliability. Decouple VDD with a 100 nF ceramic capacitor placed close to the supply pin, and follow Microchip AN1248 for low-power PCB layout to minimize leakage paths in battery applications.

Typical Applications
PIC16F15344-I/GZ is suitable for 7 applications: Battery-Powered IoT Sensor Node, Home Automation Controller, Wearable Fitness Device, Industrial Sensor Interface Module, Small Motor Control / Fan Driver, Consumer White Goods UI Board, Low-Power Wireless Peripheral / Remote Control.
Battery-Powered IoT Sensor Node
The PIC16F15344-I/GZ's XLP (eXtreme Low Power) architecture and deep-sleep current in the nanoampere range make it ideal for wireless sensor nodes that spend most of their life in standby. The 32 MHz CPU wakes in microseconds to sample, transmit, and return to sleep, while the 7 KB Flash accommodates protocol stacks like Modbus, LoRaWAN, or BLE beaconing for IoT edge devices. The 4x4 mm UQFN footprint allows the MCU to fit inside miniature sensor housings such as soil-moisture probes and wearable health patches where PCB area is at a premium. On-chip ADC with computation, comparators, and PWMs cover typical sensor signal-chain functions without external analog ICs, reducing BOM cost and quiescent draw.
Recommended
Home Automation Controller
The PIC16F15344-I/GZ provides a compelling balance of peripherals and power budget for home automation hubs that need to drive relays, read switch inputs, and communicate over UART/SPI/I2C. With 2 EUSART channels, the MCU can host an RS-485 link for HVAC equipment while simultaneously talking to a Wi-Fi or sub-GHz radio module, eliminating the need for an external UART multiplexer. The 10-bit ADC and 5-bit DAC allow direct sensing of light, temperature, and analog setpoints without extra signal conditioning. The compact 4x4 mm UQFN package supports a small-form-factor PCB that can be hidden inside standard wall-box enclosures, and XLP sleep modes keep standby power consumption well below ENERGY STAR idle thresholds.
Recommended
Wearable Fitness Device
The PIC16F15344-I/GZ's combination of XLP low-power operation, small 4x4 mm UQFN package, and integrated peripherals fits wearable fitness bands where battery life, weight, and PCB size are critical. The 32 MHz CPU delivers enough headroom for pedometer algorithms, heart-rate signal conditioning, and BLE beacon transmissions, while deep-sleep currents in the nanoampere range enable multi-week battery life on a single coin cell. The integrated CWG and PWMs drive haptic-feedback motors directly, replacing dedicated haptic driver ICs. On-chip ADC with computation (ADC2) automates averaging and threshold detection for biometric signals, reducing firmware complexity and shortening time to market.
Recommended
Industrial Sensor Interface Module
The PIC16F15344-I/GZ targets industrial 4-20 mA loop-powered sensor interfaces where robust analog peripherals and deterministic 8-bit timing are essential. Its 10-bit ADC with computation handles ratiometric bridge measurements, while the comparators implement window-detect alarm thresholds without CPU intervention. The 32 MHz core and 49-instruction enhanced mid-range architecture deliver deterministic loop times for process-control loops, and the 2 EUSART channels support both RS-485 fieldbus and debug logging simultaneously. The E/GZ variant extends the operating temperature to +125C for unconditioned outdoor enclosures. The 7 KB Flash accommodates factory calibration tables and Modbus RTU protocol stacks.
Recommended
Small Motor Control / Fan Driver
The PIC16F15344-I/GZ's integrated Complementary Waveform Generator (CWG) and four 10-bit PWM channels enable direct control of small BLDC, stepper, or DC brush motors in appliances, fans, and pumps. Hardware CIPs offload commutation timing from the CPU, freeing it for higher-level control loops while reducing firmware size. The 32 MHz instruction rate provides 31.25 ns PWM resolution, fine enough for quiet motor operation and energy-efficient variable-speed drive. The tiny 4x4 mm UQFN footprint fits inside motor-control PCBs that share board space with power-stage FETs, and XLP sleep modes reduce standby drain when the motor is idle.
Recommended
Consumer White Goods UI Board
The PIC16F15344-I/GZ serves as the user-interface controller in white goods such as coffee machines, washing machines, and microwave ovens where capacitive touch, LED indicators, and buzzer control must coexist with reliable 8-bit timing. Its 32 MHz CPU drives seven-segment or dot-matrix displays while scanning keypad matrices, and the CWG generates tones for piezo buzzers without CPU overhead. The 5-bit DAC and PWM channels dim LEDs and backlights smoothly without flicker. The E/GZ temperature variant withstands the high ambient temperatures inside appliance enclosures, and the small UQFN package suits the slim UI PCBs behind front panels.
Recommended
Low-Power Wireless Peripheral / Remote Control
The PIC16F15344-I/GZ's combination of sub-microamp sleep currents, 32 MHz CPU for fast wake-and-transmit cycles, and integrated UART/SPI/I2C peripherals makes it well-suited to battery-powered wireless remote controls and RF tag peripherals. The 7 KB Flash stores proprietary RF protocols or BLE link-layer code, and the on-chip ADC measures battery voltage for accurate state-of-charge reporting. The 4x4 mm UQFN footprint fits inside slim remote enclosures, and the E/GZ variant survives outdoor temperature swings in garden or gate-control applications. CIPs like the CLC and SMT implement precise RF timing without loading the CPU, lowering overall current draw.

Key Differentiators
- Compact 4x4 mm UQFN-20 footprint with full 7 KB Flash (vs PIC16F15344-I/P (20-pin PDIP))
- Extended temperature option E/GZ in same UQFN-20 footprint (vs PIC16F15344-I/GZ)
- 32 MHz CPU with hardware CIP offload (vs PIC16F1509-I/ML (20 MHz older family))
Design Notes
The 20-pin UQFN (4x4 mm) package requires a PCB with non-solder-mask-defined (NSMD) pads and a central exposed thermal pad that must be soldered to the ground plane for mechanical reliability and thermal dissipation. Place a 100 nF 0402 ceramic decoupling capacitor as close as possible to the VDD pin (within 2 mm) and add a bulk 10 uF tantalum or ceramic capacitor near the IC supply pin for low-frequency transient suppression. Follow Microchip AN1248 low-power PCB layout guidelines to minimize leakage paths that would degrade deep-sleep current.
Estimated: at 32 MHz active CPU with all peripherals running, the PIC16F15344-I/GZ draws approximately 5-7 mA from a 3.3 V supply, while in deep sleep with RAM retention current drops below 100 nA. For battery-life calculations, estimate duty cycle carefully: typical IoT sensor nodes spend 99% of time in sleep, making average current dominated by wake-and-transmit bursts. Use the internal HFINTOSC rather than an external crystal when possible to eliminate the crystal's quiescent current.
Do not confuse the UQFN (GZ) package with the QFN package from other vendors - the UQFN-20 (4x4 mm) footprint has a unique 0.4 mm pitch and central thermal pad that does not match standard QFN-20 land patterns. Always verify the PCB land pattern against Microchip's package specification document (drawing C04-30202) rather than relying on generic QFN templates. Also confirm the MCLR pin (RA3) configuration - leaving it unconnected without proper configuration can cause the device to enter reset unexpectedly.
Route the ICSP programming pins (ICSPCLK on RA1 and ICSPDAT on RA0) to accessible test points or a programming header so that firmware can be updated in production. For low-noise analog designs, separate the analog AVREF and VDD pins with a ferrite bead and provide a separate analog ground island. Place the external crystal (if used) within 5 mm of the OSC1/OSC2 pins and guard the traces with a ground pour to reduce EMI susceptibility.
