PIC16F15344-E/GZ - 8-bit XLP MCU, 7KB Flash, 20-UQFN | Microchip
MPN: PIC16F15344-E/GZ ✓ Hoạt độngPIC16F15344-E/GZ Tóm tắt
An 8-bit microcontroller (MCU) is a programmable integrated circuit built around an 8-bit data bus and a Harvard or modified-Harvard architecture. Within the broader hierarchy, an MCU sits inside the microcontrollers category, which itself is a subset of embedded processors and ultimately of digital integrated circuits. The PIC16F15344 belongs to Microchip's enhanced mid-range PIC16F core family, distinguished by 49 instructions and 16 stack levels, optimized for deterministic real-time control and ultra-low power consumption.
Key features include a wide operating voltage range of 1.8 V to 5.5 V, ultra-low-power IDLE and DOZE modes, an on-chip 32 MHz internal oscillator, configurable logic cells (CLC), Complementary Waveform Generator (CWG), Numerically Controlled Oscillator (NCO), and multiple communication peripherals such as EUSART, I2C, and SPI. The XLP architecture typically delivers nanoWatt sleep currents, supporting battery-powered applications that must operate for years on a single cell.
The 20-UQFN (4x4 mm) package provides an extremely compact footprint suited for space-constrained designs, while the exposed pad aids thermal performance. Integrated peripheral pin select (PPS) simplifies board routing by allowing digital peripheral I/O to be remapped across most pins, reducing PCB layout complexity in mixed-signal designs.
Typical applications include IoT sensor nodes, battery-powered wearables, home automation, low-power wireless HMI front ends, and consumer white goods. The combination of XLP nanoWatt technology, flexible peripherals, and a small footprint also suits medical monitoring accessories and industrial sensor hubs. When designing with this device, leverage IDLE/DOZE modes aggressively and configure the NCO + CLC for hardware-based timing to keep the CPU asleep for most of the duty cycle.

Ứng dụng tiêu biểu
PIC16F15344-E/GZ phù hợp cho 6 Áp dụngs: Battery-Powered IoT Sensor Node, Home Automation and Smart Home Devices, Wearable Health and Fitness Accessories, Industrial Sensor and Control Modules, Consumer White Goods and Appliance UI, Low-Power Wireless HMI / Remote Controls.
Battery-Powered IoT Sensor Node
The PIC16F15344-E/GZ is a strong fit for battery-powered IoT sensor nodes where multi-year battery life and a compact PCB footprint are essential. Its 1.8 V to 5.5 V operating range supports direct connection to single-cell CR2032, two-AA, or Li-ion chemistries without external level shifting, while the XLP nanoWatt sleep current and IDLE/DOZE modes let the CPU remain asleep for >99% of a typical duty cycle. The on-chip 10-bit ADC with computation, two comparators, and integrated temperature sensor handle many sensor front-ends without external analog ICs. The 20-UQFN (4x4 mm) package keeps board area below ~30 mm², ideal for coin-cell or sealed wireless sensor enclosures.

Home Automation and Smart Home Devices
In smart-home hubs, occupancy sensors, and battery-powered wall switches, the PIC16F15344-E/GZ delivers the right blend of peripherals, including EUSART, I2C, SPI, PWM, and the CWG for driving LEDs or triacs. Peripheral Pin Select (PPS) greatly simplifies mixed-signal PCB layout by remapping digital functions across most pins, which is critical when a small 20-UQFN footprint must route multiple communication buses simultaneously. The XLP technology keeps standby power well under 1 µA for battery-backed or energy-harvested switches, while CIPs like CLC and NCO enable hardware-based timer and pulse logic without waking the CPU.

Wearable Health and Fitness Accessories
For wearable bands, fitness patches, and remote patient monitoring accessories, the PIC16F15344-E/GZ offers the small 4x4 mm UQFN footprint, low BOM cost, and nanoWatt sleep currents required for weeks-to-months of battery life. The 10-bit ADC with computation and two on-chip comparators can directly interface with optical heart-rate, skin-conductance, or temperature sensors, while the integrated EUSART and I2C simplify pairing with BLE or Wi-Fi companion modules. The CIPs (CLC, NCO, CWG) enable event-driven peripheral chains that keep the CPU asleep between samples.

Industrial Sensor and Control Modules
Industrial 4-20 mA loop sensors, Modbus RTU nodes, and small PLC expansion cards benefit from the PIC16F15344-E/GZ's -40 C to +125 C industrial temperature range, robust 1.8-5.5 V supply tolerance, and the enhanced mid-range core's deterministic interrupt latency. The EUSART with LIN support, plus the on-chip 10-bit ADC, can simultaneously serve analog input modules and isolated serial links. Hardware CIPs offload PWM-driven proportional valves, triac dimming, and zero-cross detection, simplifying firmware and improving EMI robustness in noisy industrial environments.

Consumer White Goods and Appliance UI
The PIC16F15344-E/GZ is well-suited for washing machine, dishwasher, and small kitchen appliance user-interface boards that need capacitive touch decoding, LED indication, and simple serial communication. The CWG and PWM peripherals directly drive status LEDs, buzzers, and triac/MOSFET gates for relays or heaters, while the integrated EUSART and I2C link to the main appliance controller. XLP nanoWatt standby reduces phantom-power consumption in standby mode, an increasingly important metric for energy-rated appliances.
Được đề xuất
Low-Power Wireless HMI / Remote Controls
For sub-GHz or BLE-paired remote controls and small HMIs, the PIC16F15344-E/GZ provides enough MIPS to drive an SPI OLED or segment LCD, scan key matrices, and orchestrate radio handshakes via UART. The XLP technology enables coin-cell-powered remotes that last for years, and the on-chip comparators can implement brown-out and low-battery detection without external components. The compact 20-UQFN package is easy to place inside thin plastic enclosures.

Ghi chú thiết kế
Leverage IDLE and DOZE low-power modes aggressively: keep the CPU asleep whenever peripheral flags (ADC, comparators, CLC, timers) can drive the application logic. According to the Microchip PIC16F15344 datasheet, sleep currents in the XLP nanoWatt range allow CR2032-powered nodes to operate for years if the average system current stays below ~5 µA. Estimated: with 100 ms wake intervals and an average active current of 1 mA for 1 ms, average draw is ~15 µA, leaving ample margin for sensor and radio activity.
Always bond the UQFN exposed pad (pin 18 in this listing) to a generous ground copper pour. The EP provides both heat sinking and a low-inductance ground reference for analog measurements. Per the manufacturer layout guidelines, place a via-in-pad or via-array directly under the EP and stitch surrounding ground pours to suppress switching noise on adjacent analog and ADC inputs.
Use the on-chip Peripheral Pin Select (PPS) to route I2C, SPI, EUSART, and PWM signals away from high-noise traces and adjacent analog ADC channels. The 20-UQFN footprint is dense, so per-pin remapping prevents costly rework. Keep the VDD decoupling capacitor within 3 mm of the VDD pin and add a 10 µF bulk cap shared with the EP ground pour.
Do not assume all PIC16F1509 firmware will run on a PIC16F15344 without review: the CIP peripheral set (CLC, NCO, CWG, DSM) and PPS register layout differ between families, and the Flash/EEPROM map also shifts. Always rebuild against the PIC16F15344 header files and re-validate interrupt vectors, ADC channel mapping, and pin assignments before porting.
