PIC16LF15345-E/6NVAO Übersicht
A microcontroller (MCU) is a single-chip computer containing a CPU, memory (Flash/RAM), and programmable peripherals. The PIC16LF15345 belongs to the PIC16 family, an 8-bit RISC architecture family that sits below PIC18/PIC24 and dsPIC33 in Microchip's product hierarchy, all of which fall under the broader category of embedded microcontrollers and 8-bit/16-bit MCUs within the semiconductor industry. The "F" in PIC16F denotes Flash-based program memory, while "LF" denotes the low-voltage (1.8 V min) XLP subfamily.
Key features include Core Independent Peripherals (CIPs) such as the CWG, Configurable Logic Cells (CLC), and Numerically Controlled Oscillator (NCO) that offload tasks from the CPU, enabling deterministic real-time response without software overhead. The device supports up to 32 MHz operation at 3.0 V and is rated for the extended -40 °C to +125 °C automotive temperature range, making it suitable for AEC-Q100 Grade 1 automotive applications. The "AO" suffix designates automotive qualification per Microchip's ordering convention.
Typical applications include IoT sensor nodes, automotive body and lighting controllers, battery-powered consumer devices, low-power remote controls, and small appliances with HMI or LED driving requirements. Its combination of CWG, PWM, and ADC-with-computation makes it well-suited to BLDC motor commutation, power-supply sequencing, and closed-loop fan control.
Design consideration: this part ships in a 20-pin VQFN (6N) - small no-lead footprint requiring careful PCB layout and exposed-pad thermal/ground soldering for reliable production yields. Verify your pick-and-place and reflow profile are qualified for 0.5 mm pitch QFN packages.

Typische Anwendungen
PIC16LF15345-E/6NVAO ist geeignet für 6 Anwendungs: Automotive Body and Lighting Controllers, Battery-Powered IoT Sensor Nodes, Small Appliance HMI and User Interface, BLDC Fan and Small Motor Control, Remote Control and Wireless HID, Industrial Sensor Signal Conditioning.
Automotive Body and Lighting Controllers
The PIC16LF15345-E/6NVAO is well-matched to automotive body and lighting controller applications thanks to its AEC-Q100 Grade 1 qualification ('AO' suffix), -40 C to +125 C operating range, and integrated CIP peripherals. The Complementary Waveform Generator (CWG) produces hardware-timed switching for LED drivers, FET half-bridges, and DC motor commutators without CPU overhead, while the 10-bit ADC with computation handles thermistor or current-sense inputs synchronously with the PWM. Four independent PWM channels cover RGB lighting, HVAC flaps, or seat-position motors, and the 1.8-3.6 V range aligns with body-control modules running off a 3.3 V post-regulator. PPAP and IMDS documentation ship with the AO suffix parts, simplifying Tier-1 supplier onboarding.
Empfohlen
Battery-Powered IoT Sensor Nodes
The PIC16LF15345-E/6NVAO's XLP nanoWatt technology makes it ideal for battery-powered IoT sensor nodes. Sleep currents below 30 nA (Sleep with RTCC) and Deep Sleep around 60 nA enable multi-year operation from coin-cell or 2xAA batteries. The CLC (Configurable Logic Cell) and CWG allow hardware-only wake-on-event from sensor edges, while the CPU sleeps - a unique feature that offloads routine sensing without firmware intervention. The 32 MHz internal oscillator (factory-trimmed to +/-2%) removes the external crystal BOM for compact designs, and the 14 KB Flash comfortably fits lightweight protocol stacks like LoRaWAN device drivers or Bluetooth LE HCI bridge firmware to companion radios.
Empfohlen
Small Appliance HMI and User Interface
For small-appliance human-machine interfaces (HMIs) like coffee makers, air purifiers, and countertop ovens, the PIC16LF15345-E/6NVAO provides a balanced mix of I/O, ADC, and PWM resources. Its 18 I/O pins comfortably drive capacitive-touch sensors via the Peripheral Touch Controller (PTC, available on selected family variants), LED segment displays, and rotary encoder inputs. The 10-bit ADC with computation handles temperature and humidity sensor inputs in real time without CPU burden. The eXtreme Low-Power operation allows battery-backed RTC retention during power loss, so user-set clock and preference data survive line-voltage interruptions without supercap or coin-cell redundancy.
Empfohlen
BLDC Fan and Small Motor Control
The PIC16LF15345-E/6NVAO is well-suited to brushless DC (BLDC) fan and small motor control applications because the integrated CWG and 10-bit PWM generate complementary switching signals with hardware dead-band insertion, eliminating software timing jitter. The four PWM channels handle phase drive, braking, and a tachometer input simultaneously, while the comparators provide hardware overcurrent protection with sub-microsecond response. The 32 MHz instruction rate allows Field-Oriented Control (FOC) loops on small motors under 50 W. AEC-Q100 Grade 1 qualification extends these benefits to automotive coolant pumps, electronic seat fans, and HVAC blowers operating in harsh thermal environments.
Empfohlen
Remote Control and Wireless HID
For handheld remote controls, key fobs, and wireless human-interface devices, the PIC16LF15345-E/6NVAO delivers the right balance of Flash, RAM, and nanoWatt sleep. Its 14 KB Flash accommodates vendor-specific wireless stack fragments or RF4CE protocol glue, while the 1 KB RAM buffers HID reports. The two EUSART modules can simultaneously interface a low-power sub-GHz transceiver (e.g., the Microchip MRF89XA) and an IrDA transceiver for legacy universal-remotes. Sleep currents below 60 nA ensure coin-cell battery life measured in years rather than months, even with daily use.
Empfohlen
Industrial Sensor Signal Conditioning
The PIC16LF15345-E/6NVAO serves well in industrial 4-20 mA loop-powered sensor transmitters and signal-conditioning front-ends. Its 1.8-3.6 V operation fits the post-regulator rail of loop-powered designs, the 10-bit ADC with computation oversamples and averages to 12-bit effective resolution, and the integrated comparators form hardware window detectors for alarm thresholds without CPU latency. Two EUSARTs support HART or Modbus RTU framing on a single UART while leaving the other free for factory calibration. The extended temperature range (-40 to +125 C) covers process-industry enclosure ratings without derating.

Designhinweise
Estimated: the PIC16LF15345-E/6NVAO in the 20-pin VQFN (6N) 5x5 mm package has a theta_JA around 40-50 C/W on a standard 4-layer JEDEC test board (datasheet thermal table). For full AEC-Q100 Grade 1 operation at +125 C ambient with continuous 32 MHz CPU activity, follow the datasheet's PCB thermal layout - expose the package thermal pad to a continuous bottom-side copper pour stitched with at least 8 thermal vias to the internal ground plane. The exposed pad must be soldered to the PCB for both mechanical reliability and thermal dissipation.
The 20-pin VQFN (6N) uses 0.5 mm pitch with a center thermal pad (pin 21). Per Microchip's VQFN package footprint recommendations, the land pads should be 0.30 mm wide with 0.50 mm pitch, and the thermal pad should be approximately 3.5 x 3.5 mm with at least 8 plated-through vias (0.30 mm drill) stitched to the inner ground plane. Reflow profile must not exceed the JEDEC J-STD-020 MSL3 moisture sensitivity rating - the 6N package is rated MSL3 unless otherwise noted. Failure to follow the proper footprint results in solder opens or thermal pad voids that cause field failures under thermal cycling.
The PIC16LF15345 LF (low-voltage XLP) variant typically draws 7-9 mA at 32 MHz / 3.3 V active, dropping to <2 mA at 1 MHz, and into the nanoWatt range in Sleep mode. Estimate: 4-6 mA at 16 MHz / 3.3 V with peripherals active, and ~30 nA Sleep with RTCC running. Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 8) and a bulk 1-10 uF tantalum or ceramic on the same supply node. The VSS pin (pin 7) should connect directly to the ground plane with a via-in-pad style stub - do not daisy-chain VSS between pins.
Common pitfalls when designing with this part: (1) Selecting the F variant (PIC16F15345) instead of the LF variant for sub-2.3 V supplies - the F variant brown-outs below 2.3 V. (2) Forgetting that the RA3 pin on PIC16 mid-range MCUs is input-only by default, and configuring it as output produces undefined behavior. (3) Leaving the internal MCLR disabled but not providing an external pull-up on RA3 - this allows spurious resets during brown-out events. (4) Using the same I/O pin for both ICSPDAT and a high-current load during programming - the ICSP interface requires the load to be high-impedance during programming to avoid contention. (5) Not enabling the WDT (Watchdog Timer) - while not strictly required, leaving WDT off is a common field-failure root cause for software-lockup-induced automotive warranty returns.
