PIC16LF18424-E/P Übersicht
A PIC (Peripheral Interface Controller) microcontroller is a compact, low-power programmable device that integrates a CPU, non-volatile program memory (Flash), volatile data memory (RAM), EEPROM, and a set of on-chip peripherals into a single IC. PIC MCUs sit within the broader taxonomy of microcontrollers -> embedded microprocessors -> microcomputer ICs -> semiconductors. The 8-bit PIC16 family uses a Harvard RISC architecture with a 14-bit instruction word, and the "LF" prefix denotes the low-voltage, low-power "XLP" (eXtreme Low-Power) silicon process optimized for battery-driven and energy-harvesting designs.
Key features include active current consumption as low as ~32 uA/MHz at 3.3V, a nanoWatt XLP sleep current of roughly 30 nA typical, and an integrated 32MHz internal oscillator that eliminates the need for an external crystal in many designs. The 12-bit ADCC enables on-chip averaging, oversampling, and automated threshold comparisons, while the CWG and PWM peripherals simplify synchronous power-stage and lighting-control loops. Together these peripherals support digitally controlled analog loops without CPU intervention.
Architecturally, the PIC16LF18424 combines the mid-range 16-bit instruction set extension with a peripheral-rich analog front-end, making it well suited to mixed-signal sensor nodes. Its internal oscillator, programmable reference and on-chip temperature indicator reduce external BOM while the 14-pin PDIP package remains breadboard-friendly for prototypes.
Typical applications include battery-powered IoT sensor nodes, low-cost consumer remote controls, LED lighting control, simple motor/gate-drive timing, portable medical accessories, and industrial sensor interfaces. The wide 1.8V-3.6V supply window lets designers run directly from single-cell Li-coin or two alkaline cells.
When designing with this device, place a 0.1 uF decoupling capacitor adjacent to VDD and provide a bulk cap on the MCLR pull-up network. Verify unused I/O configuration in firmware (digital vs analog) to avoid unintended current draw in XLP sleep modes.

Typische Anwendungen
PIC16LF18424-E/P ist geeignet für 6 Anwendungs: Battery-Powered IoT Sensor Node, Consumer Remote Control, LED Lighting & PWM Control, Portable Medical Accessory, Industrial Sensor Interface, Home Appliance User Interface.
Battery-Powered IoT Sensor Node
The PIC16LF18424-E/P's 1.8V-3.6V LF supply range and nanoWatt XLP sleep current (tens of nA typical) make it ideal for coin-cell IoT sensor nodes. The 12-bit ADCC with on-chip averaging supports ratiometric temperature, humidity, and gas-sensor readings, while the integrated 32MHz oscillator removes the need for an external crystal. Real-world deployments report multi-year battery life on a single CR2032 when duty-cycled at <1% active time.
Empfohlen
Consumer Remote Control
The PIC16LF18424-E/P fits IR/RF remote-control applications because of its 7 KB Flash (ample for protocol stacks), EUSART for BLE bridge commands, and PWM for LED backlight dimming. Low XLP sleep current keeps the design idle for years on AAA cells, and the 32MHz internal oscillator avoids crystal BOM. Typical reference designs use the comparator for battery-voltage monitoring during TX bursts.
Empfohlen
LED Lighting & PWM Control
The PIC16LF18424-E/P's two PWM modules and CWG (Complementary Waveform Generator) simplify LED dimming and half-bridge LED-driver timing. The 32MHz CPU clock provides fine PWM resolution at high switching frequencies, and the 5-bit DAC plus 12-bit ADCC support closed-loop brightness and color-mixing loops. The PDIP-14 package is convenient for through-hole retrofit modules and dimmer designs.
Empfohlen
Portable Medical Accessory
For handheld medical peripherals such as pulse-oximeter probes, glucometer docks, and spirometer tubes, the PIC16LF18424-E/P offers a reliable extended-temperature grade (-40C to +125C), LF 3.6V max supply for two-alkaline-cell operation, and on-chip 12-bit ADCC for accurate analog front-end sampling. Low sleep current prolongs battery life on infrequent-use devices. Hardware ECC and parity-free Flash simplify medical firmware updates.
Empfohlen
Industrial Sensor Interface
The PIC16LF18424-E/P serves industrial 4-20mA loop-powered sensors and Modbus RTU slaves thanks to its EUSART, RS-485-friendly timing, and extended temperature grade. On-chip ADCC averages noisy transducer signals, while the integrated 5-bit DAC supports 0-10V analog outputs. The PDIP-14 package simplifies maintenance in field-replaceable modules and DIN-rail carriers.
Empfohlen
Home Appliance User Interface
The PIC16LF18424-E/P's 11 I/O pins drive segmented LED displays, capacitive touch pads (via the on-chip comparator), and PWM-driven buzzer tones for appliance HMI. The 7 KB Flash is enough for menu state machines, while XLP sleep modes let battery-backed appliance clocks idle for months. The PDIP-14 package is favored for service-friendly through-hole repairs.

Wichtigste Unterscheidungsmerkmale
- 12-bit ADCC with on-chip computation vs 10-bit ADC on older families (vs. PIC16LF1824-E/P)
- Extended -40C to +125C temperature grade available without redesign (vs. PIC16LF18424-I/P)
- XLP 1.8V-3.6V supply enables direct coin-cell operation (vs. PIC16F18424-I/P)
Designhinweise
Place a 0.1 uF decoupling capacitor as close as possible to the VDD pin (pin 14) and a bulk 1-10 uF capacitor near the IC. The LF silicon runs on 1.8V-3.6V; verify that any upstream LDO or battery can sustain peak CPU active currents near 32MHz. The /MCLR pin (pin 1) needs a 10k pull-up to VDD; do not leave it floating.
Configure unused I/O pins as digital outputs tied low (or high) and disable analog functions via ANSEL registers. Leaving analog-enabled pins floating can add tens of uA per pin in XLP sleep modes. Also confirm the WDT, BOR, and LVR configurations in CONFIG words match the application's noise and brown-out environment - unexpected resets are a frequent PIC16 first-prototype issue.
For PDIP-14 layouts, keep the decoupling capacitor within 2-3mm of VDD; the long lead inductance of through-hole capacitors can introduce ringing at 32MHz. For mixed-signal designs, dedicate a separate analog trace from VDD to AV-DD-cap and keep digital return currents away from the ADC reference node. ICSP programming pins (ICSPCLK/ICSPDAT) need series resistors only if they are also user-accessible.
Compliance-Informationen
RoHS compliant per Microchip product page. The PIC16LF18424-E/P is not AEC-Q100 qualified; for AEC-Q100, choose the PIC16LF18424-E/P (VAO) automotive variant.
