PIC16F15325-I/ST Overview
An 8-bit microcontroller is a microprocessor core that processes data eight bits at a time, paired with on-chip FLASH, RAM, and peripherals. Within the broader semiconductor taxonomy it sits under MCU -> microcontroller -> embedded processor -> semiconductor device. PIC microcontrollers from Microchip use a Harvard RISC architecture with separate program and data buses, giving deterministic instruction throughput and a mature toolchain (MPLAB X IDE, XC8 compiler).
Key features of the PIC16F15325 include 14KB FLASH, 1KB RAM, 4 PWM channels, a comparator, a 5-bit and 10-bit DAC, ADC, 4 CLC (Configurable Logic Cell) blocks, a CWG (Complementary Waveform Generator), and 2x EUSART with SPI/I2C. The XLP technology delivers nanoWatt sleep currents, suiting battery-powered designs. The 14-TSSOP package has a 0.173-inch (4.40 mm) body width for compact boards.
Architecturally, the PIC16F15325 uses the enhanced mid-range core with a 14-bit instruction word and a hardware multiplier for faster math. The CIPs allow PWM, communications, and timing to operate without CPU intervention, freeing the CPU for application logic and improving deterministic response in real-time control.
Typical applications include low-power IoT sensor nodes, consumer appliances, LED lighting controls, battery-powered instruments, and general-purpose embedded control. The combination of small package size, low sleep current, and integrated peripherals also suits wearable health and remote-monitoring products.
When designing with the PIC16F15325-I/ST, route the ICSP/ICD pins (PGD/PGC) directly to an in-circuit programming header for field-updatable firmware, place the VDD/VSS decoupling capacitors within 5 mm of the supply pins, and respect the 14-TSSOP thermal envelope when the device drives high-current loads via the I/O pins.

Typical Applications
PIC16F15325-I/ST is suitable for 7 applications: Low-Power IoT Sensor Nodes, Consumer Appliance Control, LED Lighting Controllers, Battery-Powered Instruments, Wearable Health Devices, Automotive Body Electronics, Industrial Sensor Interfaces.
Low-Power IoT Sensor Nodes
The PIC16F15325-I/ST's XLP nanoWatt technology and Core Independent Peripherals make it well suited for battery-powered IoT sensor nodes that wake periodically, take a measurement, transmit over a low-power radio, and return to sleep. Its 4 PWM channels drive sensor excitation or LED indicators, the ADC samples analog sensors, and the 2x EUSART/SPI/I2C interfaces connect to radios like the MRF89XA or LoRa modules. With sleep currents under 1 uA, the device can run for years on a CR2032 cell. Place the MCU between the battery and the radio module with decoupling within 5 mm of VDD/VSS.

Consumer Appliance Control
For consumer appliance control panels, the PIC16F15325-I/ST offers 14KB FLASH for state machines and UI logic, plus 4 PWM channels to drive triac-controlled loads, LED indicators, or small motors. The CWG (Complementary Waveform Generator) simplifies half-bridge and full-bridge motor or solenoid drive with programmable dead-band. Its 14-TSSOP package fits compact control boards behind keypads or touch panels. The integrated comparator and 5/10-bit DAC handle closed-loop control without external components, reducing BOM cost.

LED Lighting Controllers
The PIC16F15325-I/ST drives RGB and white LED lighting products using its 4 PWM channels to generate high-resolution color mixing and dimming curves. The CLC blocks can implement custom logic for color sequencing without CPU intervention, freeing the core for communication and user interface tasks. The XLP sleep mode reduces standby power below 1 uA, meeting Energy Star and EU ecodesign standby limits for connected lighting. The 14-TSSOP package suits both bulb retrofit modules and low-profile fixture controllers.
Recommended
Battery-Powered Instruments
In portable battery-powered instruments such as digital thermometers, hand-held multimeters, and data loggers, the PIC16F15325-I/ST provides 14KB FLASH for calibration tables, user interface, and measurement routines. Its ADC with internal voltage reference, combined with the on-chip temperature sensor, supports measurement accuracy within 1-2 C without external components. The XLP sleep mode enables multi-year battery life in shipping-mode and idle states. Pair the MCU with the MCP1700 LDO and an I2C EEPROM like 24LC256 for data logging.
Recommended
Wearable Health Devices
For wearable health and fitness devices, the PIC16F15325-I/ST combines small 14-TSSOP package size, low active current under 1 mA at 1 MHz, and XLP sleep currents in the nanoAmp range to maximize runtime on coin-cell or LiPo batteries. Its 2x EUSART and I2C interfaces connect to biometric sensors such as heart-rate monitors and accelerometers, while the 4 PWM channels drive haptic feedback motors. The integrated ADC and DAC simplify analog front-end design for bio-impedance or optical sensors.
Recommended
Automotive Body Electronics
The PIC16F15325-I/ST is suitable for non-safety automotive body applications such as interior lighting, seat controllers, and HVAC actuators. Its LINbus connectivity integrates directly into automotive LIN networks, and the 4 PWM channels drive LED strings or small DC motors. The industrial -40C to +85C temperature range covers cabin environments. For under-hood or safety-critical applications, select the AEC-Q100 qualified PIC16F15325 variants. The 14-TSSOP withstands automotive vibration profiles when properly board-mounted.
Recommended
Industrial Sensor Interfaces
In industrial 4-20 mA loop-powered sensor transmitters, the PIC16F15325-I/ST's low active current and XLP sleep modes allow the entire transmitter to run from the loop's 3.5 mA minimum supply. Its ADC with PGA, on-chip DAC, and 2x EUSART/SPI/I2C interfaces support HART or wireless HART modems. The 14-TSSOP package fits the small cylindrical sensor housings common to pressure and flow transmitters. Industrial -40C to +85C rating and RoHS compliance meet factory automation certification requirements.

Design Notes
The PIC16F15325-I/ST operates from 2.3V to 5.5V (F variant) and supports multiple low-power modes. Use the SLEEP instruction with peripherals configured for interrupt wake to achieve nanoAmp standby currents. Estimated: with all peripherals off and VDD at 3.3V, sleep current is typically under 1 uA. Place a 100 nF decoupling capacitor within 5 mm of the VDD pin and a bulk capacitor (4.7 uF or larger) on the supply rail for transient suppression.
For 14-TSSOP layout, route the ICSPDAT (RA0) and ICSPCLK (RA1) signals directly to a programming header with no series components - MPLAB ICD tools require direct access to these pins. Keep analog signals (ADC inputs) away from PWM and switching traces to reduce noise coupling. The exposed thermal pad is not present on 14-TSSOP; ensure at least 0.5 oz copper pour on VDD and VSS traces for current handling.
Configuration bits must be set correctly: enable the internal oscillator for stand-alone operation, configure the MCLR/RA3 pin as input or reset per application, and disable unused peripherals via the PXCON registers to minimize leakage. Failure to configure the Configuration Word can cause the device to remain in reset or with peripherals driving the I/O pins incorrectly. Verify BOR and POR thresholds match the application's supply characteristics.
When using the PIC16F15325's EUSART at high baud rates (>1 Mbps), ensure the SPI or UART traces are length-matched and routed over a continuous reference plane. The ADC readings can be degraded by high-frequency switching on adjacent pins; use the ADC's dedicated channel selection and add a 100 ns acquisition time delay in software. According to Microchip's analog design notes, an RC filter on the ADC input (1 kohm + 100 nF) improves measurement stability in noisy environments.
