PIC16F15385-I/PT Overview
A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory (typically Flash), volatile working memory (RAM), and a configurable set of digital and analog peripherals. PIC16F family MCUs are RISC-based 8-bit microcontrollers from Microchip widely deployed in low-power and cost-sensitive embedded designs; they sit at the small-form-factor end of the broader microcontroller hierarchy (MCU -> embedded controller -> semiconductor IC).
Key features include 4 PWMs, an on-chip comparator, a 5-bit/8-bit/10-bit DAC, an ADC with Computation, a Complementary Waveform Generator (CWG), 4 Configurable Logic Cells (CLC), 2 EUSART, and SPI/I2C communication. The XLP technology enables sleep currents down to nanoampere levels, making the device well-suited for battery-powered applications such as remote sensors and IoT endpoints.
The PIC16F15385 uses an enhanced mid-range 8-bit RISC core with a 14-bit instruction word, providing deterministic instruction timing suitable for real-time control. The integrated CIPs (CLC, CWG, NCO, DSM) implement logic, waveform generation, and signal conditioning entirely in hardware, offloading tasks from the CPU and reducing firmware complexity and power consumption.
Typical applications include low-power IoT sensor nodes, consumer electronics control, battery-operated remote controls, LED lighting drivers, small motor control loops, and general-purpose embedded systems requiring multiple serial interfaces and PWM channels. The wide operating voltage and XLP modes also suit energy-harvesting designs.
When designing with this part, ensure decoupling follows Microchip's guidelines (typically a 100nF ceramic plus a bulk capacitor near VDD) and verify I/O voltage levels match peripheral expectations. Programming is supported via MPLAB X IDE and the PICkit/SNAP debuggers.

Typical Applications
PIC16F15385-I/PT is suitable for 6 applications: Low-Power IoT Sensor Nodes, Consumer Electronics Control, LED Lighting Drivers, Small Motor Control, Battery-Operated Remote Controls, General-Purpose Embedded Systems.
Low-Power IoT Sensor Nodes
The PIC16F15385-I/PT is well-suited for IoT sensor nodes because its XLP technology delivers nanoampere-level sleep currents and its 2.3-5.5V VDD range supports direct Li-ion or 2x AA battery operation. The integrated ADC with Computation can wake the CPU only when a threshold is crossed, enabling duty-cycled sensing that minimizes total system energy. At a 32 MHz active CPU, the device still completes sensor reads and transmits in milliseconds before returning to deep sleep. The 4 Configurable Logic Cells (CLC) let designers implement sensor conditioning (PWM generation, edge detection, signal gating) in hardware, offloading tasks that would otherwise require CPU wake-ups. For a typical temperature/humidity sensor node transmitting every 5 minutes, average current budgets of <5 uA are achievable.
Recommended
Consumer Electronics Control
The PIC16F15385-I/PT serves as a cost-effective main controller in consumer electronics such as remote controls, small appliances, and personal care devices. Its 4 PWM channels drive LED brightness, motor speed, or piezo buzzers directly, while the 2 EUSART and SPI/I2C peripherals connect to displays, sensors, and wireless modules. The 14 KB Flash comfortably fits user-interface state machines plus BLE/Zigbee command handlers. The 48-TQFP package exposes sufficient I/O for keypad scanning, rotary-encoder input, and multiple status LEDs. Designers leverage the CWG (Complementary Waveform Generator) for half-bridge driver timing without CPU intervention.
Recommended
LED Lighting Drivers
The PIC16F15385-I/PT excels in LED lighting drivers thanks to its 4 independent PWM channels, 10-bit DAC for color-mixing references, and the on-chip comparator for over-temperature or current-limit feedback. Designers implement dimming curves, color-temperature blending, and DMX-style addressable lighting protocols in firmware while the CLCs handle glue logic between sensor inputs and PWM outputs. The wide VDD range (2.3-5.5V) supports both 3.3V logic LEDs and 5V analog drive chains. Industrial temperature grade (-40C to +85C) accommodates outdoor or in-fixture thermal environments.
Recommended
Small Motor Control
The PIC16F15385-I/PT handles small DC and stepper motor control loops in appliances, toys, and industrial valve actuators. The Complementary Waveform Generator (CWG) produces hardware-timed complementary PWM outputs for half-bridge / full-bridge FET drivers, while the 4 PWMs drive independent channels or a 4-wire stepper. The ADC samples current-sense amplifiers for closed-loop torque/speed regulation. Combined with the on-chip comparator for back-EMF zero-cross detection in BLDC commutation, the '15385 reduces external component count. The 32 MHz CPU enables field-oriented control (FOC) loops for low-speed BLDC applications under careful scheduling.
Recommended
Battery-Operated Remote Controls
The PIC16F15385-I/PT is a strong fit for handheld remote controls thanks to XLP sleep currents below 50 nA (with proper configuration) and fast wake-up to 32 MHz. A coin-cell or 2x AAA powered remote can sit idle for years between button presses. The integrated ADC scans resistive keypads, while the CLCs debounce and encode button events without CPU wake. SPI/I2C ports connect to wireless transceivers (sub-GHz, BLE, or IR) with deterministic timing for protocol bit-banging if a hardware peripheral is not used. The industrial temperature grade supports automotive keyfob and outdoor applications.
Recommended
General-Purpose Embedded Systems
The PIC16F15385-I/PT is a versatile general-purpose embedded controller for HVAC accessories, security peripherals, industrial sensors, and instrumentation front-ends. The 14 KB Flash and 1 KB RAM accommodate protocol stacks (Modbus RTU over EUSART, I2C sensor aggregation) plus application logic. The 48-TQFP provides ample I/O for parallel displays, keypads, and multiple sensor channels. The 4 CLCs implement custom glue logic (e.g., frequency multiplication, PWM gating, signal interlocks) without external CPLD components. Industrial temperature grade (-40C to +85C) and wide VDD tolerance suit both indoor and outdoor installations.

Design Notes
Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the VDD pin and a bulk capacitor (1-10 uF) on the same rail. Microchip's PIC16F153xx family datasheet recommends the 100 nF cap regardless of operating frequency to suppress high-frequency noise on internal logic. For battery applications, place the bulk capacitor as close as practical to the IC to handle inrush during sleep-to-active transitions. The XLP modes require clean VDD; a noisy rail may prevent reaching the deepest sleep states and elevate quiescent current by orders of magnitude.
Route ICSPDAT and ICSPCLK traces with no series components longer than a few millimeters; place 4.7 kohm pull-ups on both lines to VDD if in-circuit programming is required in production. The 48-TQFP exposed pad (if present on this variant) should be soldered to a thermal pad tied to the ground plane to reduce thermal resistance. Keep switching nodes (PWM-driven FET gates, motor phases) physically separated from analog ADC traces to minimize coupled noise into sensor readings.
Do not omit the MCLR pull-up resistor (typically 10 kohm to VDD); without it the device may intermittently reset or fail to start. Configuration bits must be set before code execution; a freshly erased PIC has default configuration that may not match your application's clock and watchdog expectations. When migrating from another PIC16F1xxx family, verify peripheral register names - this family uses CLCxSEL, CWGxCON, etc., and differs from older PIC16F families in PPS mapping. Finally, respect VDD ramp time; very slow VDD rise may cause POR-related issues on the BOR configuration.
Assign analog-capable pins for ADC and DAC channels to avoid signal integrity loss from digital functions; the PIC16F153xx datasheet designates specific pins as ANx and DACxOUT. Place the voltage reference (if used) decoupling cap near the reference pin to stabilize conversions. For high-speed SPI or EUSART, keep trace lengths matched and use a ground reference plane directly underneath. Designers should review the package-specific land pattern dimensions (e.g., 48-TQFP pitch 0.5 mm) and follow IPC-7351 nominal or density-level pads.
