PIC16F15344-E/P Overview
An 8-bit PIC microcontroller (MCU) is a single-chip computer that combines an 8-bit CPU core, Flash program memory, RAM, EEPROM, and a rich set of analog and digital peripherals into a compact IC optimized for embedded control. It sits within the broader hierarchy: microcontroller -> embedded processor -> semiconductor device. Microchip's PIC16F family is widely adopted in consumer, industrial, and IoT products because the architecture is deterministic, the toolchain (MPLAB X IDE, XC8 compiler, MPLAB Code Configurator) is free, and CIPs (Core Independent Peripherals) offload tasks from the CPU.
Key features include a 10-bit ADC with computation (ADC2), two 8-bit DACs, two high-speed comparators, an 8-bit timer (Timer2), a 16-bit timer (Timer1), and four Configurable Logic Cells (CLCs) that allow glue-logic functions to be implemented in hardware without CPU intervention. Core Independent Peripherals such as the CWG (Complementary Waveform Generator), NCO (Numerically Controlled Oscillator), and four 10-bit PWMs enable motor, lighting, and signal-generation functions while the CPU sleeps.
Typical applications include IoT sensor nodes running on coin-cell batteries, low-power wireless remote controls, HVAC thermostat front panels, smart lighting ballasts, and small appliance user interfaces. The dual EUSART, SPI, and I2C interfaces support bridges to sensors, displays, and external radios; the 32 MHz internal oscillator eliminates an external resonator on most designs.
When designing with this device, prefer the internal 32 MHz HFINTOSC to minimize BOM cost and reserve the two GPIO-capable pins for wake sources. Always enable the watchdog timer in software if the application is safety-relevant, since the XLP sleep currents are below 50 nA in Retention mode.

Typical Applications
PIC16F15344-E/P is suitable for 6 applications: Battery-Powered IoT Sensor Node, HVAC Thermostat Front Panel Controller, Small Appliance User Interface, Automotive Interior Lighting Controller, Industrial Sensor Transmitter (4-20 mA), Smart LED Lighting Controller.
Battery-Powered IoT Sensor Node
The PIC16F15344-E/P suits battery-powered IoT sensor nodes because its XLP Sleep current drops below 50 nA in Retention mode and the 32 MHz HFINTOSC eliminates an external crystal, reducing BOM cost and standby drain. Its 10-bit ADC with computation (ADC2) oversamples and averages sensor readings autonomously, freeing the CPU to remain in Sleep between acquisitions; this pattern extends coin-cell life by 5-10x versus cyclic-wake designs. With 7 KB Flash and 512 bytes SRAM, the device can run a small LoRaWAN/Sigfox stack, basic authentication, and CIP-driven sensor handling. Designers pair it with an SPI sensor and an EUSART-attached transceiver, drawing under 2 uA average current at one wake per minute.
Recommended
HVAC Thermostat Front Panel Controller
For HVAC thermostat front panels, the PIC16F15344-E/P drives character LCDs, scans keypad matrices, and modulates HVAC valves using its four 10-bit PWMs and CWG (Complementary Waveform Generator) without CPU intervention. The two 8-bit DACs generate reference voltages for thermistor bridges, and the comparators provide zero-cross detection for triac-based load control. Operating from a 24VAC-derived 5V rail, the -40C to +125C extended temperature grade handles attic-mounted installations. With CIPs running in hardware, the core spends most of its time in IDLE at 1.8 mA, drawing under 10 mA average even with continuous LCD refresh.
Recommended
Small Appliance User Interface
Coffee makers, blenders, and induction cooktops benefit from the PIC16F15344-E/P's Configurable Logic Cells (CLCs) that combine PWM edges, comparator events, and timer overflows into custom control signals without software polling. The 8-bit DACs modulate LED brightness for capacitive-touch feedback rings, while the high-speed comparators handle zero-voltage switching for triac-driven heater loads, eliminating inrush current stress. The 256-byte EEPROM stores user presets (brew size, blend profile) across power cycles without external memory. Industrial-grade temperature tolerance suits the elevated ambient of motor-compressor compartments.
Recommended
Automotive Interior Lighting Controller
The PIC16F15344-E/P serves automotive interior lighting controllers by generating smooth RGB PWM dimming curves through its four 10-bit PWM channels and CWG dead-band control. The NCO (Numerically Controlled Oscillator) produces precise DALI or LIN-bus timing for ambient lighting modules, while LIN compatibility on the EUSART interfaces directly with body controllers. Operating from 12V battery through a 5V LDO, the -40C to +125C extended grade covers cabin temperature extremes. Although not AEC-Q100 qualified, the E/P variant is widely used in non-safety automotive interior subsystems where functional reliability is sufficient.
Recommended
Industrial Sensor Transmitter (4-20 mA)
Two-wire 4-20 mA industrial sensor transmitters use the PIC16F15344-E/P because its 2.0V minimum VDD supports loop-powered operation from as little as 3.5 mA at 12V compliance. The 10-bit ADC2 reads bridge-type pressure or load sensors with hardware oversampling, while the 8-bit DAC generates the 4-20 mA current via a PWM-fed op-amp loop. The CLCs implement HART-style FSK modulation without CPU loading, and the CWG drives the loop-side power MOSFET for efficient regulation. Industrial -40C to +125C operation handles outdoor process-control cabinets.
Recommended
Smart LED Lighting Controller
Addressable LED strip and architectural lighting controllers leverage the PIC16F15344-E/P's NCO and CWG peripherals to generate precise WS2812/SK6812 timing waveforms in hardware, freeing the CPU to handle higher-level DMX or DALI commands over EUSART. The 32 MHz core can bit-bang legacy 0-10V dimming signals while four PWM channels drive analog LED drivers simultaneously. With 7 KB Flash, complex color-mapping and fade algorithms fit comfortably, and the XLP Sleep modes reduce standby consumption below 100 nA for battery-backup emergency fixtures. Wide VDD tolerance supports both 3.3V and 5V LED string topologies.

Key Differentiators
- 7 KB Flash in a 20-pin PDIP package with full CIP set (vs PIC16F15323-E/P)
- Industrial extended -40C to +125C temperature grade (vs PIC16F15344-I/P)
- Modern CIP peripherals (CLC, CWG, NCO, ADC2 with computation) (vs PIC16F15244-I/P)
- 32 MHz operation across full 2.0V-5.5V VDD range (vs PIC16F15244-I/P)
Design Notes
Estimated: at 32 MHz CPU and all peripherals active, VDD = 5V, the PIC16F15344 draws approximately 4 mA. Disabling unused peripherals via PMD (Peripheral Module Disable) registers typically saves 1-2 mA; activating XLP IDLE with peripherals disabled drops consumption below 1.8 mA. For battery applications, configure HFINTOSC to remain stable across Sleep wake-ups by enabling the INTOSC stability lock; this avoids the 2 ms crystal-startup penalty on each wake.
The 20-pin PDIP package has a theta_JA of approximately 70 C/W in still air and 50 C/W with moderate airflow. At maximum ambient (+85C industrial or +125C extended), the die dissipates under 250 mW across all clock and VDD combinations, well within thermal limits. For continuous 32 MHz operation at 5.5V, derate by limiting ambient to +100C in enclosed enclosures without forced airflow; the E/P variant's 125C junction limit provides 25C of headroom.
Place a 100 nF decoupling capacitor within 5 mm of the VDD pin (pin 1) and a bulk 10 uF tantalum or ceramic capacitor on the same supply trace. Connect pin 4 (MCLR) to VDD through a 10 kohm pull-up resistor; if in-circuit debugging is required, add a 5 kohm series resistor to allow ICD 4 programming without disconnecting the MCLR line. Route the ICSPDAT and ICSPCLK lines away from PWM and ADC traces to avoid coupling.
Do not leave unused pins floating - configure them as outputs driving low or as inputs with the internal weak pull-up enabled to avoid SCL/SDA-like latch-up from injected current. The ADC2 channel selection bits must be cleared before changing the channel to avoid spurious first-sample artifacts. The CLC configuration registers are write-protected in Configuration mode; unlock via the CLCKEY sequence before modifying CLC setups during runtime.
For I2C bus operation above 400 kHz, add 4.7 kohm pull-ups rather than relying on the internal weak pull-ups (which are typically 20-50 kohm and exceed bus rise-time specs). For SPI at 8 MHz, keep trace lengths under 50 mm and place a 100 ohm series resistor at the SCK driver to dampen reflections on multi-slave buses.
Compliance Information
RoHS compliant and lead-free per Microchip product page. Not AEC-Q100 qualified - not intended for safety-critical automotive applications. Extended temperature grade E suffix (-40C to +125C) provides industrial reliability but is not automotive-qualified.
