PIC16LF18345-E/GZVAO - 8-bit MCU, 14KB Flash, 32MHz | Microchip
MPN: PIC16LF18345-E/GZVAO ✓ פעילPIC16LF18345-E/GZVAO סקירה
An 8-bit microcontroller is a single-chip computer built around an 8-bit data-path CPU, on-chip Flash and RAM, and a curated set of analog and digital peripherals. The PIC16 family sits in Microchip's mid-range PIC portfolio, sitting hierarchically between PIC10/12/16 baseline parts and the PIC18/dsPIC33 high-performance parts. PIC16F devices use a RISC architecture with a fixed instruction set tuned for deterministic interrupt response and very low active current. Combined with integrated Core Independent Peripherals (CIPs), the PIC16LF18345 can handle signal generation, waveform timing, and inter-module glue logic without CPU intervention, leaving the core free for application code.
Key features of this MCU include 12 or 18 selectable I/O pins, a 10-bit ADC with computation, 5-bit and 8-bit DACs, two 10-bit PWMs, Capture/Compare/PWM (CCP), Complementary Waveform Generator (CWG), Configurable Logic Cell (CLC), Numerically Controlled Oscillator (NCO), and Peripheral Pin Select (PPS) for flexible digital routing. The ICSP/ICD debug interface is supported through the standard 6-pin header. Operating temperature spans -40C to +125C (automotive 'E' grade).
Architecturally, the device uses a Harvard-style 14-bit instruction word with a 2-stage pipeline, allowing most instructions to complete in one instruction cycle (4 system clock cycles). PPS remapping lets designers assign digital peripherals to almost any I/O pin after PCB layout, greatly simplifying routing in dense mixed-signal designs.
Typical applications include automotive body electronics and sensor conditioning, ultra-low-power IoT sensor nodes, battery-powered wearables, LED lighting control with CWG-driven high-resolution dimming, and general-purpose motor control using CCP/PWM. The AEC-Q100 qualification also suits it for under-hood and cabin electronics.
When designing with this device, select the LF variant (as here) for battery-powered or 3.3V systems. For 5V-only boards, choose the PIC16F18345 version. Keep the analog and digital supply traces short and decoupled with 100 nF + 1uF bulk caps placed within 5 mm of the VDD pins.

יישומים טיפוסיים
PIC16LF18345-E/GZVAO מתאים עבור 7 יישוםs: Automotive Sensor Conditioning, Ultra-Low-Power IoT Sensor Nodes, LED Lighting Control with High-Resolution Dimming, Battery-Powered Wearables, Small Motor Control (DC, Stepper, Fan), Industrial Control and HMI, General Purpose Mixed-Signal Glue Logic.
Automotive Sensor Conditioning
The PIC16LF18345-E/GZVAO suits automotive body and sensor modules where AEC-Q100 qualification is mandatory. Its 10-bit ADC with computation handles thermistor, Hall-effect, and pressure-sensor signal conditioning directly, while the CLC and CWG blocks generate custom timing and waveform signals without CPU load. Operating from 1.8-3.6 V supports direct battery-monitor circuits with nanoWatt sleep, dropping quiescent current below 100 nA between CAN-LIN wake-up polls to preserve quiescent drain.
מומלץ
Ultra-Low-Power IoT Sensor Nodes
The XLP nanoWatt technology on this MCU enables battery-powered wireless sensor nodes that wake only on timer or interrupt, transmit, and return to sleep. With 14 KB Flash it fits BLE/Zigbee stack fragments plus sensor processing. The NCO and CLC peripherals perform signal generation entirely in hardware, freeing the CPU to remain asleep. PPS allows the same PCB to route SPI/I2C to multiple sensor options without redesign, accelerating IoT product family variants.
מומלץ
LED Lighting Control with High-Resolution Dimming
The CWG (Complementary Waveform Generator) plus two 10-bit PWMs produce high-resolution dimming for LED drivers, ideal for architectural and automotive interior lighting. The 32 MHz core clocks PWM at up to 32 kHz with sub-microsecond resolution, eliminating visible flicker. Hardware fault shutdown via CLC outputs protects against LED open/short conditions within microseconds, critical for safety-rated lighting designs.
מומלץ
Battery-Powered Wearables
For wearable designs on a single CR2032 or Li-ion coin cell, this MCU's 1.8-3.6 V operation, sub-microamp sleep current, and 14 KB Flash are well matched. PPS and CLC let one hardware platform implement multiple wearable SKUs (heart-rate, step-counter, temperature patch) by routing peripherals differently in firmware. The 4x4 mm UQFN footprint fits wristbands and patch modules where board area is severely constrained.
מומלץ
Small Motor Control (DC, Stepper, Fan)
The CCP and 10-bit PWM channels, paired with the CWG for complementary drive signals, deliver flexible motor control for brushed DC and unipolar stepper motors. The NCO provides precise frequency synthesis for stall-detection algorithms, while the ADC samples back-EMF for closed-loop speed control. The 1.8-3.6 V LF supply matches battery and small fan motor rails directly, with no level shifters needed.
מומלץ
Industrial Control and HMI
Industrial control panels, simple HMI keypads, and process-signal conditioners benefit from this MCU's mix of analog (10-bit ADC, 5/8-bit DAC) and digital (CLC, CWG, NCO) peripherals. The -40C to +125C automotive temperature grade exceeds typical industrial -40C to +85C requirements, providing extra margin in factory-floor enclosures. UART, I2C, and SPI peripherals enable straightforward integration with industrial sensors and HMI displays.
מומלץ
General Purpose Mixed-Signal Glue Logic
Beyond traditional applications, the CLC blocks let this MCU replace discrete logic gates, timers, and analog filters in mixed-signal systems. Engineers can implement custom boolean equations, frequency multiplication, and edge-detection directly in hardware that runs independently of the CPU clock. This shrinks BOM, reduces board area, and provides firmware-upgradable logic - a substantial advantage over hard-wired discrete solutions.

הערות תכנון
Decouple VDD with both a 100 nF ceramic capacitor placed within 5 mm of the VDD pin and a 1 uF bulk capacitor. Place the 100 nF cap on the same side as the MCU to minimize loop area. For battery-powered designs, route VDD through a ferrite bead if the supply comes from a switching regulator to filter residual ripple. The nanoWatt sleep current specification assumes clean VDD with no >50 mV noise spikes.
Route analog and digital traces on separate layers or grouped zones, with the AGND pin star-grounded back to a single point near the MCU. Keep ADC traces short and away from PWM signals. The exposed pad (EP) on the UQFN package must be soldered to a copper pour connected to VSS for thermal dissipation and mechanical reliability. Stitching vias around the EPAD reduce thermal impedance.
Do not exceed 3.6 V on VDD for the LF variant - the part will be damaged immediately. When migrating from PIC16F18345 to PIC16LF18345, verify that the clock-source configuration bits match the new voltage range; some LF configurations disable HFINTOSC at 32 MHz below 2.0 V. Always configure unused I/O as OUTPUT LOW rather than INPUT to avoid floating-pin current draws of several hundred microamperes in sleep.
When using PPS to remap high-speed peripherals like SPI or PWM, keep traces matched in length to within 5 mm to preserve signal integrity at 32 MHz core clock. Place series resistors (22-33 ohm) on PWM outputs if driving long cables to dampen ringing. For ADC sampling, add a 1 nF cap at the ADC input pin to filter RF noise - the 10-bit ADC has a 4 us acquisition time that benefits from external filtering.
