PIC16F15325-E/ST 개요
A microcontroller (MCU) is a single-chip computer containing a CPU, memory (Flash/RAM/EEPROM), and integrated peripherals on one substrate. The PIC16F15325 belongs to the 8-bit PIC16 family, which sits in the broader hierarchy: microcontroller -> embedded processor -> semiconductor device. Within Microchip's portfolio, it targets the 'low-power general-purpose with intelligent analog' segment, leveraging XLP technology for sub-uA sleep currents that compete head-to-head with MSP430 and low-end STM32 devices.
Key features include up to 32MHz CPU speed, four 10-bit PWM outputs, two EUSART/SPI/I2C peripherals, a CWG for complementary driver signals, four CLC blocks that implement state machines in hardware without CPU intervention, and a peripheral pin select (PPS) that remaps digital functions to any I/O pin. The device operates from 2.3V to 5.5V across the -40C to +125C industrial temperature range, with the '-E/' extended-temperature suffix guaranteeing -40C to +125C operation.
Architecturally, the PIC16F15325 uses Microchip's enhanced mid-range 8-bit core with a 14-bit instruction word and a hardware multiplier. The CIPs (CLC, CWG, NCO, PWM) execute deterministically without CPU wake-up, freeing the core for higher-level tasks. A unified interrupt controller with vectored priorities accelerates real-time response. Internal voltage reference and Fixed Voltage Reference (FVR) modules enable ratiometric ADC measurements.
Typical applications include low-power IoT sensor nodes, battery-powered HVAC transmitters, LED lighting controllers, consumer appliances with touch/proximity sensing, and small motor control loops using the CWG. Designers select this part for cost-sensitive nodes that need analog integration and CIP-based offloading without migrating to a 16-bit DSC.
When designing with this MCU, allocate the PPS mapping table before laying out the PCB so digital functions map to physically convenient pins. Place a 0.1uF decoupling capacitor within 5 mm of every VDD pin and reserve a 4.7uF bulk capacitor on the main rail for sleep-current spikes.

일반적인 애플리케이션
PIC16F15325-E/ST 적합 용도: 6 애플리케이션s: Battery-Powered IoT Sensor Node, LED Lighting and Color Controller, Industrial HVAC Transmitter, Small Brushless DC Motor Controller, Consumer Appliance User Interface, Automotive Body Electronics (Sub-Node).
Battery-Powered IoT Sensor Node
The PIC16F15325-E/ST fits battery-powered IoT sensor nodes through its XLP technology that drops quiescent current below 1 uA in deep sleep, paired with four CLC blocks that let wake-on-sensor logic run without waking the CPU. Per the Microchip PIC16F153xx datasheet, the 32 MHz core executes ADC reads and EUSART transmissions in microseconds, so the part wakes briefly, services the sensor, and returns to sleep - maximizing coin-cell life. Designers typically pair this MCU with a sub-GHz or BLE module that the PIC gates via a CLC-controlled power switch.
추천
LED Lighting and Color Controller
For LED lighting, the PIC16F15325-E/ST provides four 10-bit PWM channels and a Complementary Waveform Generator (CWG) that produces dead-band-corrected complementary outputs for half-bridge LED drivers. Per the Microchip datasheet 40001985C, the 5-bit/8-bit DAC drives an analog current reference for tunable-white or RGB nodes, while the four CLC blocks handle zoning logic in hardware. Compared with a discrete 555-timer design, the PIC approach yields fewer components, finer dimming resolution, and field-upgradeable firmware via ICSP.
추천
Industrial HVAC Transmitter
Industrial HVAC transmitters benefit from the PIC16F15325-E/ST's extended -40C to +125C temperature range, integrated 10-bit ADC for temperature/humidity sensing, and EUSART for 4-20 mA or RS-485 loop output. Per Microchip datasheet 40001985C, the on-chip comparator enables zero-crossing detection for solid-state relay drive, while the CWG can generate the PWM carrier for a switched-mode loop supply. This integration replaces multiple op-amps and timers in traditional HVAC designs.
추천
Small Brushless DC Motor Controller
Small BLDC motor controllers leverage the PIC16F15325-E/ST's CWG to generate six-step complementary drive waveforms with programmable dead time, eliminating an external gate-driver state machine. Per the Microchip PIC16F153xx datasheet, the four PWM channels provide speed and torque control, while back-EMF zero-crossing is detected by the on-chip comparator feeding a CLC interrupt. Designers size the CLC to debounce the comparator and avoid false commutation at low RPM.
추천
Consumer Appliance User Interface
Consumer appliance UIs such as washing-machine displays, coffee-machine keypads, and induction-cooktop touch panels use the PIC16F15325-E/ST's four CLC blocks for capacitive-touch decoding in hardware, plus four PWMs for indicator-LED dimming. According to the Microchip datasheet 40001985C, the EUSART links the panel to the main appliance MCU while the DAC drives an analog bar-graph or seven-segment reference. Compared with a dedicated touch IC, the integrated approach shrinks BOM and improves EMC by avoiding a separate I2C touch bus.
추천
Automotive Body Electronics (Sub-Node)
Automotive body sub-nodes (mirror controllers, ambient lighting, seat-position switches) benefit from the PIC16F15325-E/ST's extended -40C to +125C range and AEC-Q100-capable silicon in the same family, with PWM channels for motor drive and EUSART for LIN-bus stacking. Per Microchip's PIC16F153xx product page, AEC-Q100 qualification is part-specific, so verify the part number with the automotive-grade ordering suffix before using this MCU in production vehicles. The CIPs offload LIN collision timing and PWM dead-band from the CPU.

설계 노트
Decouple VDD (pin 1) with a 0.1 uF ceramic within 5 mm and a 4.7 uF bulk on the rail. The PIC16F15325-E/ST draws sub-uA in deep sleep but can spike to several mA during ADC conversions and EUSART transmissions. Estimated: at 32 MHz, VDD = 3.3 V, and full peripheral activity, average current is ~3 mA; placing bulk capacitance on the rail prevents 50 mV dips that could reset the brown-out detector. Use PMD bits to gate any unused ADC, PWM, or EUSART peripherals during sleep to keep quiescent current below 1 uA per Microchip XLP datasheet 40001985C.
Route the ICSP clock and data lines (PGx and PDx) away from PWM or switching signals to avoid injected noise during in-circuit programming. Place a 4.7 kohm pull-up on MCLR if MCLR is enabled in configuration words; otherwise tie MCLR directly to VDD through a 0 ohm resistor that can be populated for development boards. Per Microchip PIC16F153xx layout guidelines, keep analog inputs RC0/RC1/RC2 short and guarded by a ground trace to minimize ADC cross-talk at the 10-bit conversion level.
When using the CWG to drive a half-bridge, add at least 200 ns of programmable dead-band time to prevent shoot-through across the high-side and low-side FETs. The PIC16F15325-E/ST CWG allows up to 1024 TCY of dead-band per datasheet. Estimate: at 32 MHz oscillator (TCY = 125 ns), the maximum dead-band is ~128 us, sufficient for most sub-MHz switching applications. Verify with a scope on the gate-drive node at full load before locking the BOM.
Do not leave the MCLR pin floating. Either disable MCLR in configuration words and use it as RA3, or pull MCLR to VDD with a 4.7 kohm resistor. Floating MCLR can cause spurious resets under EMI. Also remember the ADC reference can be VDD or the internal FVR (Fixed Voltage Reference) - selecting FVR when VDD is noisy will yield more stable conversions but introduces 25 uA bias current. Per Microchip datasheet 40001985C, the FVR is stable only after a 30 us startup delay.
