PIC16F15345-I/SS Visão geral
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path that integrates a CPU, non-volatile program memory (Flash/ROM), volatile data memory (RAM), and peripherals such as timers, ADCs, and communication interfaces. PIC16F MCUs from Microchip use a RISC (Reduced Instruction Set Computer) Harvard architecture with separate program and data buses. This category sits at the intersection of microcontrollers, embedded controllers, and CMOS logic ICs within the broader semiconductor taxonomy, and the PIC16F15345 belongs to Microchip's PIC16F153xx XLP family optimised for ultra-low-power, mixed-signal applications.
The PIC16F15345-I/SS offers eXtreme Low Power (XLP) operation with multiple power-managed modes including doze, idle, and sleep. The device supports up to 32 MHz internal oscillator, 14 KB self-programmable Flash, 1 KB SRAM, 256 B EEPROM, and 18 dedicated I/O pins with interrupt-on-change capability on select pins. Peripheral pin select (PPS) is not present on this 20-pin variant, but the device exposes all standard peripherals via fixed pin assignments.
The core employs an 8-bit RISC CPU with single-cycle execution for most instructions, an 8-level hardware stack, and a fast interrupt response. The instruction set is compatible with the broader PIC16 mid-range family, easing firmware portability. The CLC module allows combinatorial and sequential logic to be implemented in hardware without external glue logic, while the CWG produces complementary PWM outputs for half-bridge and full-bridge driver stages.
Typical applications include low-power IoT sensor nodes, home appliance control, LED lighting controllers, battery-powered instrumentation, automotive body electronics sub-modules, and industrial sensor interfaces. The rich analog and digital peripheral mix also makes it suitable for fan control, small BLDC driver boards, and general-purpose embedded control where PIC16 code reuse is desired.
When designing with the PIC16F15345-I/SS, verify the brown-out reset and watchdog timer configuration at startup, and ensure the ICSP programming pins (RA0/RA1) are not permanently pulled low in the application. The 20-pin SSOP package delivers compact board area for space-constrained designs.

Battery-Powered IoT Sensor Node
The PIC16F15345-I/SS is well suited for battery-powered IoT sensor nodes that demand sub-microamp sleep current. According to the Microchip PIC16F153xx datasheet, the XLP family offers nanoWatt sleep modes with hundreds of nanoamps of quiescent current, allowing coin-cell nodes to last years on a single CR2032. The 14 KB Flash accommodates small MQTT/SNMP-style stacks or custom sensor protocols, while the 10-bit ADC and integrated comparator enable direct connection to analog sensors without external signal conditioning. The 32 MHz internal oscillator removes the need for an external crystal, reducing BOM and board area. Use the CLC module to implement event-driven wake logic in hardware without CPU intervention, preserving battery life. Pair the PIC16F15345-I/SS with an external sub-GHz or BLE module for connectivity.
Recomendado
Home Appliance User Interface
The PIC16F15345-I/SS fits well in home appliance user-interface boards (washing machines, microwaves, induction cooktops) that need capacitive touch sensing, LED feedback, and a UART link to a main controller. The four CLC cells allow hardware-implemented switch debounce and pulse stretching without software overhead, while the CWG produces complementary PWM for triac-style phase control. The 10-bit ADC reads multiple thermistor inputs simultaneously via the integrated ADC, and the 5-bit DAC generates reference voltages for sensor calibration. The 20-pin SSOP package keeps board cost low, and the industrial -40C to +85C rating survives kitchen thermal stress. Firmware reuse is straightforward across the PIC16F153xx family when scaling across product variants.
Recomendado
LED Lighting and Dimming Controller
The PIC16F15345-I/SS is ideal for constant-current LED drivers and dimming controllers in commercial and residential lighting. The four PWM channels deliver high-resolution dimming with phase-shift control, and the CWG module generates complementary outputs for half-bridge LED driver topologies with hardware dead-band control, eliminating shoot-through. The integrated comparator provides over-current protection by hardware-tripping the PWM without software latency. The PIC16F15345-I/SS supports DALI, 0-10 V analog, and DMX-style digital dimming via its EUSART and SPI peripherals, allowing a single MCU to manage complex lighting protocols while keeping the BOM lean. The 32 MHz CPU handles color-mixing algorithms in real time.
Recomendado
Small BLDC Fan and Motor Control
The PIC16F15345-I/SS integrates the peripherals required for sensorless or Hall-sensor BLDC fan and pump control. The CWG produces the three-phase complementary PWM signals with programmable dead-time insertion, while the comparator with on-chip DAC enables back-EMF zero-cross detection for sensorless commutation. The 10-bit ADC samples motor current for closed-loop torque control, and the four CLC cells implement hardware fault propagation (over-current, over-temperature) directly to the PWM shutdown path. This offloads critical safety logic from software, satisfying UL/IEC motor-control safety requirements. The industrial -40C to +85C temperature rating and 2.3-5.5 V operating range make it suitable for fans and pumps in HVAC and white-goods applications.
Recomendado
Automotive Body Electronics Sub-Module
The PIC16F15345-I/SS can serve in automotive body-electronics sub-modules such as seat controllers, mirror adjusters, ambient lighting drivers, and HVAC blend-door actuators when paired with external CAN/LIN transceivers. The extended-temperature PIC16F15345-E/SS variant (same SSOP-20 footprint) operates over -40C to +125C, sufficing for cabin-mounted modules. The EUSART module supports LIN 2.x slave communication natively, while the CWG and PWM channels drive small brushed and stepper motors with hardware dead-band. The internal oscillator with 32 MHz accuracy over automotive temperature simplifies design and avoids external crystal cost. For under-hood modules requiring AEC-Q100 qualification, refer to Microchip's automotive-grade PIC16F1xxx family.
Recomendado
Industrial Sensor Interface Board
The PIC16F15345-I/SS excels in industrial sensor-interface boards that aggregate analog and digital signals, perform local processing, and forward data over RS-485, SPI, or I2C. The dual EUSART modules allow simultaneous RS-485 sensor polling and debug-log output, while the CLC cells implement hardware protocol framing for proprietary sensor buses without CPU intervention. The 10-bit ADC reads 4-20 mA loop sensors via external shunt resistors, and the integrated DAC produces excitation voltages for bridge sensors. The 14 KB Flash supports MODBUS, IO-Link, or proprietary protocol stacks, and the wide 2.3-5.5 V supply range supports 24 V industrial rails with simple linear regulation. The 20-pin SSOP allows compact PCB designs inside DIN-rail enclosures.

Notas de projeto
Pin RA3 doubles as the MCLR (master clear / reset) input on most PIC16F153xx devices. According to the Microchip PIC16F153xx datasheet, if RA3/MCLR is used as a digital I/O in the application, the internal MCLR must be disabled in the configuration words, otherwise the pin cannot be used as a general-purpose input. The /I (industrial) temperature grade part uses RA3 as a regular I/O after MCLR is disabled.
The PIC16F15345-I/SS XLP family offers nanoWatt sleep current in the sub-microamp range, but only when unused peripherals are disabled in firmware and all I/O pins are configured as analog inputs (high-impedance). According to Microchip PIC16F153xx datasheet section on power-managed modes, failing to disable unused peripherals can increase sleep current by 10-100x. Place the device into Sleep via the SLEEP instruction, and wake via external interrupt, watchdog timer, or peripheral interrupt.
Place the 0.1 uF VDD decoupling capacitor within 5 mm of the VDD pin, and add a 10 uF bulk capacitor near the MCU for switching transients. The 32 MHz internal oscillator is sensitive to VDD noise - noisy rails can cause frequency drift or dropped clock pulses. For SSOP-20 hand soldering, use a fine-tip iron and flux; for production, follow MSL handling procedures. RA0 and RA1 (ICSP programming pins) should be accessible for in-circuit programming.
When using the CWG (Complementary Waveform Generator) for half-bridge or full-bridge motor drive, set the dead-band control registers to prevent shoot-through. According to Microchip PIC16F153xx datasheet, the CWG dead-band delay is configurable in increments of the instruction clock; values of 1-2 uS are typical for MOSFET gate drivers. The CLC module can also be used to implement hardware over-current protection by combining the comparator output with the CWG shutdown input.
