PIC16F15276-E/PT Overview
A microcontroller (MCU) is a single-chip computer containing a processor core, program memory, data memory, and integrated peripherals such as ADCs, timers, and communication interfaces. The PIC16F15276 belongs to Microchip's PIC16 mid-range 8-bit MCU family, which sits between the PIC10/12/16 baseline series and the PIC18 enhanced series in the company's taxonomy. Within the power-management hierarchy, this device performs digital control of sensors and actuators rather than power conversion itself.
Key features include 32MHz maximum CPU clock (8 MIPS instruction throughput), 28KB Flash self-programmable program memory, 2KB data SRAM, 10-bit ADC with up to 28 input channels, two 10-bit PWMs, two CCP modules, and standard serial interfaces including EUSART, SPI, and I2C. Peripheral Pin Select (PPS) allows flexible signal routing, and the Hardware Limit Timer (HLT) simplifies safety-critical timing.
The PIC16F15276 architecture uses a Harvard RISC core with single-cycle instructions, achieving deterministic 125ns instruction execution at 32MHz. Intelligent Analog peripherals operate without CPU intervention, reducing software complexity. The XLP technology delivers nanoWatt sleep currents, enabling battery-powered applications with multi-year lifetimes.
Typical applications include industrial sensor interfaces, IoT edge nodes, building automation, low-power wireless sensor hubs, home appliance control, and battery-powered measurement instruments. The 10-bit ADC and PWM channels simplify motor and lighting control loops.
Designers should consider the device's 1.8V to 5.5V supply range when integrating with sensors or 3.3V/5V logic. PPS flexibility requires careful pin-map planning in MPLAB X IDE to avoid signal conflicts, and the -E temperature grade suits automotive under-hood and industrial environments.

Typical Applications
PIC16F15276-E/PT is suitable for 6 applications: Industrial Sensor Interface, IoT Edge Sensor Node, Building Automation Control, Home Appliance Control Board, Battery-Powered Measurement Instrument, LED Lighting Controller.
Industrial Sensor Interface
The PIC16F15276-E/PT suits industrial 4-20mA and 0-10V sensor interfaces where 28 ADC channels and 10-bit resolution deliver sufficient quantization for measurement of temperature, pressure, and flow. Its 1.8V-5.5V supply range operates directly from 24V industrial bus rails after regulation. PPS remaps serial peripherals to free GPIO for sensor I/O, and the HLT module simplifies safety timer implementation for IEC 61508 SIL-2 loops.
Recommended
IoT Edge Sensor Node
Battery-powered IoT edge nodes leverage the PIC16F15276-E/PT's XLP nanoWatt sleep currents below 100nA, enabling multi-year coin-cell operation. The 28KB Flash accommodates BLE/Zigbee stack plus application logic, while 2KB RAM buffers sensor data before transmission. Peripheral Pin Select routes SPI to multiple sensors, and the integrated 10-bit ADC samples analog sensors directly without external signal conditioning.
Recommended
Building Automation Control
The PIC16F15276-E/PT controls HVAC actuators, lighting dimmers, and occupancy sensors in building automation systems. Its 2 PWM channels drive LED dimming and small DC motors, while the EUSART interfaces with BACnet or Modbus transceivers for building network integration. The -40C to +125C temperature grade tolerates rooftop equipment enclosures, and 28 ADC inputs monitor multiple analog sensor types in a single MCU.
Recommended
Home Appliance Control Board
Washing machines, dishwashers, and ovens use the PIC16F15276-E/PT for motor control and user-interface management. The 2 CCP modules capture motor speed feedback while the PWM channels drive TRIAC-based heater control. The 10-bit ADC reads thermistor inputs for temperature regulation, and the EUSART interfaces with display modules or inverter boards. Robust ESD performance and the -E temperature grade suit kitchen and laundry environments.
Recommended
Battery-Powered Measurement Instrument
Handheld multimeters and portable measurement instruments benefit from the PIC16F15276-E/PT's XLP sleep modes, which extend battery life to thousands of hours. The 10-bit ADC with 28 channels measures voltage, current, and resistance in autoranging designs, while the 32MHz core performs RMS calculations and auto-zero routines in real time. The wide 1.8V-5.5V supply range supports 2x AA, 9V, and Li-ion battery chemistries.
Recommended
LED Lighting Controller
Architectural and stage LED lighting systems use the PIC16F15276-E/PT to generate multi-channel dimming curves and DMX512 control signals. Its 2 PWM channels plus 2 CCP modules provide up to 4 hardware-driven dimming outputs, while the EUSART receives DMX-512 data via RS-485 transceivers. The 32MHz core executes color-mixing algorithms with <1ms latency, and XLP modes enable battery-backed emergency-lighting variants.

Key Differentiators
- 28 KB Flash with 2 KB SRAM in 44-pin TQFP at competitive price point (vs PIC16F15274-E/PT)
- Lower cost than PIC16F15376-I/PT for applications fitting 28 KB (vs PIC16F15376-I/PT)
- Extended -40C to +125C temperature grade (E suffix) (vs PIC16F15275-I/PT)
Design Notes
Estimated: At 32MHz active CPU with all peripherals enabled, the PIC16F15276-E/PT typically draws 6-8 mA from a 3.3V supply. In Sleep mode with XLP enabled, quiescent current drops below 100nA, enabling multi-year battery operation from a CR2032 coin cell. Use the LFINTOSC (31 kHz internal oscillator) for Sleep and switch to HFINTOSC only when CPU processing is required. Decouple VDD with 100nF and 10uF capacitors placed within 5mm of each VDD pin.
PPS remapping requires explicit unlock sequence (PPSLOCK bit) before configuration writes. Forgetting this sequence causes the PPS registers to appear read-only and silently disables peripheral routing. Always consult the latest PIC16F15276 datasheet pinout diagram for the 44-pin TQFP package - the same peripheral pin is not always available on every package pin, especially across the PIC16F15256/74/75/76 family variants.
Estimated: The 44-pin TQFP (PT) package has a thermal resistance (theta_JA) of approximately 50 C/W on a standard 4-layer JEDEC test PCB. At full 32MHz CPU load and 5V supply, total power dissipation is approximately 40 mW, yielding a junction temperature rise of 2C above ambient - well within the -40C to +125C operating range. Industrial and automotive customers should still validate thermals with their actual PCB layout and enclosure.
Compliance Information
RoHS and lead-free per Microchip product page and DigiKey listing. The -E temperature grade (-40C to +125C) is suitable for industrial but is not AEC-Q100 automotive-qualified; for AEC-Q100 applications, use PIC16F15276-E/PT variants designated for automotive or consult Microchip directly.
