PIC16F15345-I/SO Übersicht
An 8-bit microcontroller (MCU) is a single-cite embedded processor combining a RISC CPU, non-volatile program memory (Flash), volatile data memory (SRAM), and configurable peripherals. Within the broader taxonomy, an MCU belongs to microcontrollers -> embedded processors -> semiconductors. The PIC16F153xx family sits in the mid-range of Microchip's 8-bit portfolio, above baseline PIC10/12/14 and below PIC18/dsPIC families, balancing cost and peripheral richness.
Key differentiating features include sleep current below 50 nA typical for XLP battery applications, 18 I/O pins with interrupt-on-change capability, internal 32MHz HFINTOSC with ±1% accuracy, and CIPs that operate without CPU intervention. Core Independent Peripherals such as the CLC, CWG, and NCO enable deterministic real-time response, freeing the core for application logic and reducing firmware complexity.
Architecturally, the PIC16F15345 uses a modified Harvard RISC core with 49 instructions, a 16-level hardware stack, and peripheral pin select (PPS) for flexible signal routing. The 10-bit ADC delivers up to 17 channels for sensor interfacing, while the 5-bit DAC supports setpoint generation for closed-loop analog control. The CWG module produces complementary PWM outputs with dead-band control for power-conversion and motor-drive stages.
Typical applications include low-power IoT sensor nodes, home appliance control panels, LED lighting controllers, small motor control boards, industrial sensor transmitters, and battery-powered metering. The combination of low power, rich analog, and CIPs makes the PIC16F15345 well suited for systems that require deterministic real-time response without an external DSP, FPGA, or additional glue logic.
When designing, allocate one 100 nF X7R decoupling capacitor per VDD pin placed within 3 mm of the lead, use the internal 32 MHz HFINTOSC unless precise baud rates are required, and reserve one CLC block for glue logic between peripherals. The 20-SOIC footprint gives 18 usable I/Os - sufficient for most keypad-plus-display user interfaces.

PIC16F15345-I/SO ist geeignet für 6 Anwendungs: Battery-Powered IoT Sensor Nodes, Home Appliance Control Panels, LED Lighting Controllers, Small Motor Control Boards, Industrial Sensor Transmitters, Battery-Powered Metering.
Battery-Powered IoT Sensor Nodes
The PIC16F15345-I/SO's XLP sleep current below 50 nA typical and 32 MHz HFINTOSC with ±1% accuracy make it ideal for battery-powered IoT edge nodes that wake periodically to read sensors and transmit over EUSART or SPI. According to the PIC16(L)F153xx datasheet, the integrated 10-bit ADC with 17 channels handles multi-sensor interfaces (temperature, light, humidity) without external analog front-end, while the 14 KB Flash accommodates sensor-fusion or LoRaWAN-style MAC stacks. Four CLCs implement hardware wake-up logic between sensor and radio, freeing the CPU for data processing and reducing total firmware footprint.

Home Appliance Control Panels
The PIC16F15345-I/SO's 18 I/O pins and 10-bit ADC suit home appliance user-interface boards where the MCU scans keypads, drives LED or LCD indicators, and reads analog sensors (NTC thermistors, potentiometers). Per the Microchip product brief, the device's CWG module generates complementary PWM outputs for triac or IGBT dimming stages on washing machines and ovens. With 14 KB program memory, firmware can hold full state-machine logic plus diagnostics, while the 256-byte EEPROM stores user preferences and calibration constants across power cycles.
Empfohlen
LED Lighting Controllers
The PIC16F15345-I/SO's four 16-bit PWM channels and Complementary Waveform Generator make it well suited for driving RGB or tunable-white LED strings with hardware-timed dimming. According to the PIC16(L)F153xx datasheet, the CWG module produces complementary outputs with programmable dead-band - critical for half-bridge LED-driver stages where shoot-through would damage FETs. The 10-bit ADC closes a feedback loop with ambient-light sensors, and four CLCs handle sequencing logic between color-temperature modes without CPU intervention, leaving the core free for DMX-512 or DALI protocol parsing.
Empfohlen
Small Motor Control Boards
The PIC16F15345-I/SO is suitable for small brushed-DC, stepper, or low-voltage BLDC motor control, with its four 16-bit PWMs providing independent phase control and the CWG module generating complementary drive signals with hardware dead-band insertion. According to the Microchip product brief, the integrated 5-bit DAC supports reference-voltage generation for closed-loop current control, and the 10-bit ADC with 17 channels reads back shunt voltages, BEMF, and potentiometer inputs. With 14 KB Flash, the firmware can implement PI current loop plus speed/position state machine in a single-chip solution.
Empfohlen
Industrial Sensor Transmitters
The PIC16F15345-I/SO's industrial -40C to +85C operating range, 10-bit ADC, and dual EUSART interfaces make it well suited for industrial 4-20 mA sensor transmitters. According to Microchip's datasheet, the EUSART modules support RS-485 Modbus RTU and legacy RS-232 simultaneously, enabling multi-protocol sensor heads. The 14 KB Flash holds calibration curves for thermocouple or RTD linearization, while 256 bytes of EEPROM stores user-configurable ranges and tag IDs. XLP sleep modes extend battery life in field-mounted wireless transmitters, which currently need to operate for years without service.
Empfohlen
Battery-Powered Metering
The PIC16F15345-I/SO's combination of XLP low-power operation, 14 KB Flash, 1 KB SRAM, and dual EUSART interfaces suits battery-powered metering (gas, water, heat, electricity sub-metering) where the device must count pulses, run compensation algorithms, and periodically report to a wireless concentrator. Per the PIC16(L)F153xx datasheet, the device's CLCs can implement quadrature decoding for flow meters without CPU load, and the 10-bit ADC supports battery-voltage measurement for state-of-charge reporting. With sub-50 nA sleep current, a metering board can operate 10+ years on a single lithium primary cell.

Wichtigste Unterscheidungsmerkmale
- Four CLCs plus CWG plus NCO give the strongest CIP combination in the PIC16 mid-range family (vs. PIC16F18855-I/SO)
- Same-brand -E/SO drop-in with extended temperature grade at no design change (vs. PIC16F15345-E/SO)
- XLP sleep current below 50 nA typical enables multi-year battery life (vs. PIC16F18855-I/SO)
Designhinweise
Estimated: at 32 MHz with all peripherals active, VDD = 5V, and 75% CPU utilization, core current is approximately 5-7 mA. Add 1 mA per active PWM/CWG output. For battery-powered designs running on 3 V coin cells, use Sleep mode aggressively - per the PIC16(L)F153xx datasheet, XLP Sleep draws below 50 nA typical, enabling multi-year operation. Place a 100 nF X7R decoupling capacitor on each VDD pin within 3 mm of the lead, plus a bulk 10 uF tantalum or ceramic on the supply rail.
Route the ICSPPGD (RB5/DATA) and ICSPCLK (PGC) signals as short, parallel traces with ground guard to preserve programming reliability. Per Microchip's ICSP specification, both signals should have series resistors (typically 10 kohm) for in-circuit programming isolation if the application uses these pins for high-current loads. Keep analog ADC traces away from PWM outputs and the CWG driver - the 20-SOIC layout should dedicate one full ground plane under the MCU with vias stitching the perimeter for EMI suppression.
Three common pitfalls: (1) Do not exceed 5.5V on any pin - the PIC16F15345 is a 5V-tolerant device at VDD only, not at I/O; (2) When migrating from PIC16F1xxxx legacy parts, check PPS remapping - older PICs fixed peripherals to specific pins, while PIC16F15345 requires PPS configuration in firmware before peripherals work; (3) The MCLR pin (RA3) is input-only and must not be driven high as an output. Per Microchip documentation, leaving MCLR floating can cause spurious startup - tie it to VDD through a 10 kohm pull-up unless external reset is required.
Estimated: at full CPU load (32 MHz, all peripherals active), the PIC16F15345-I/SO in 20-SOIC dissipates approximately 30-40 mW. With theta_JA near 70 C/W for a small 2-layer board, junction temperature rise is roughly 2-3 C above ambient - thermal management is generally not a concern. However, in enclosed housings with no airflow, derate maximum ambient by 10-15 C. For extreme-temperature applications, choose the PIC16F15345-E/SO (extended -40C to +125C grade) to maintain reliability.
Compliance-Informationen
RoHS compliant and lead-free per Microchip product page. AEC-Q100 qualification not available for the I-grade variant; choose PIC16F15345-E/SO with -40C to +125C grade for harsh-environment or automotive under-hood applications.
