PIC16F18323-I/SL Visão geral
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path and Harvard or modified Harvard architecture, integrating a CPU, non-volatile program memory (Flash), volatile data memory (SRAM), EEPROM for parameter storage, plus a rich set of on-chip peripherals such as ADC, timers, PWM, comparators and serial interfaces. The PIC16F18323 belongs to the eXtreme Low Power (XLP) family, positioned within the broader PIC16 8-bit hierarchy: PIC16F18323 -> PIC16F183xx sub-family -> PIC16F1xxx enhanced mid-range family -> 8-bit PIC microcontrollers -> Microchip MCU portfolio -> embedded microcontrollers.
Key specifications include 12 I/O pins, 5-channel 10-bit ADC with computation (ADC^2), two comparators, a configurable logic cell (CLC), complementary waveform generator (CWG), numerically controlled oscillator (NCO), 4 8-bit timers plus 1 16-bit timer, and an enhanced Universal Synchronous/Asynchronous Receiver/Transmitter (EUSART) plus SPI and I2C. Core Independent Peripherals (CIPs) execute ADC triggering, waveform generation and signal conditioning without CPU intervention, freeing the core for application code.
Typical applications include battery-powered IoT sensor nodes that exploit the XLP idle/doze currents, low-cost consumer remote controls using the CWG for IR modulation, LED driver modules using the NCO or PWM channels, general-purpose timer/counter replacement and signal-conditioning boards using the CLC. The Peripheral Pin Select (PPS) feature allows remapping of digital peripherals to any I/O, easing PCB layout constraints.
When designing with this MCU, reserve one I/O line for ICSPDAT/ICSPCLK unless using the dedicated pins, and place the 0.1uF VDD decoupling capacitor within 5mm of the power pin. The -I suffix indicates the industrial temperature grade (-40C to +85C), suitable for outdoor or industrial enclosures.

Aplicações típicas
PIC16F18323-I/SL é adequado para 6 aplicaçãos: Battery-Powered IoT Sensor Nodes, Consumer Remote Controls (IR / RF), LED Lighting Drivers and Effects, Low-Cost Sensor Signal Conditioning, Industrial Control and Monitoring, Smart Home / Wearable Hubs.
Battery-Powered IoT Sensor Nodes
The PIC16F18323-I/SL is well-suited to battery-powered IoT sensor nodes thanks to its XLP family sleep current in the low-nanampere range and 1.8 V to 5.5 V VDD range, which lets it run directly from a single CR2032 or 2xAA cell without a boost regulator. The 10-bit ADC with computation (ADC^2) samples and filters sensor data autonomously while the core sleeps, and the EUSART wakes the MCU on UART activity. Designers typically place a 0.1 uF VDD decoupling cap within 5 mm of pin 12 and use a sleep current under 50 nA to hit a 5-year coin-cell life on periodic sensor wake-ups.
Recomendado
Consumer Remote Controls (IR / RF)
The Complementary Waveform Generator (CWG) and Numerically Controlled Oscillator (NCO) on the PIC16F18323-I/SL produce precisely modulated IR carrier waveforms for line-of-sight remote controls without CPU load. Combined with a 32 MHz HFINTOSC, the CWG can output a 38 kHz carrier with sub-microsecond duty-cycle resolution, and PPS remaps the CWG output to any I/O pin, freeing board layout. In a typical TV remote the MCU draws under 1 uA standby current between button presses while waiting on a wakeup interrupt, and the 3.5 KB Flash comfortably fits NEC, RC5 or Sony SIRC encoders.
Recomendado
LED Lighting Drivers and Effects
The PIC16F18323-I/SL drives LED strings using its 16-bit PWM/CCP channels and CWG, providing smooth brightness ramp curves and effects such as fade and chase without CPU overhead. The 5-bit DAC generates reference voltages for analog-controlled LED drivers, while the Configurable Logic Cell (CLC) implements glue logic like AND/OR gates on the board. With 12 I/O pins and 3.5 KB Flash, the MCU fits multi-channel RGBW lighting controllers and runs a user-configurable pattern table from Flash, with PWM frequencies above 1 kHz for flicker-free operation.
Recomendado
Low-Cost Sensor Signal Conditioning
Using the PIC16F18323-I/SL's CLC, comparators and ADC with ADC^2 hardware averaging, designers can build on-board signal conditioning for low-frequency analog sensors such as thermistors, photodiodes, or strain gauges without external op-amps. The two comparators provide windowed or threshold detection and generate interrupts that wake the MCU from sleep, while the 10-bit ADC digitises the conditioned signal with hardware-averaged oversampling for better than 10-bit effective resolution. The 14-SOIC footprint makes it an inexpensive drop-in for analog-front-end subassemblies.
Recomendado
Industrial Control and Monitoring
Industrial control applications benefit from the PIC16F18323-I/SL's -40C to +85C industrial temperature range, EUSART for RS-485 half-duplex links via an external transceiver, and Core Independent Peripherals that handle deterministic timing without firmware jitter. The 32 MHz CPU and PPS make the MCU responsive to fast digital inputs while leaving the core free for application logic such as PID loops. Designers should still derate the operating life for harsh environments and use the extended-temperature PIC16F18323-E/SL for -40C to +125C applications.
Recomendado
Smart Home / Wearable Hubs
The PIC16F18323-I/SL operates as a small low-cost hub for smart-home button panels, occupancy sensors, or wearable patches, where its XLP sleep mode and fast wakeup from peripheral interrupts keep average system current under 5 uA. With built-in I2C/SPI and an EUSART, the MCU interfaces with sensors and radios (BLE, sub-GHz transceivers) while the CLC handles protocol glue. The 14-SOIC package and 1.8 V minimum VDD make it easy to integrate into coin-cell-powered wearable designs.

Notas de projeto
Estimated: At VDD = 3.3 V and 32 MHz active, typical PIC16F18323 current draw is on the order of a few mA (per Microchip datasheet DC characteristics graph); in XLP sleep with WDT off the device draws tens of nA. For battery applications, use the Doze and Idle modes and wake the core only via peripheral interrupts to achieve coin-cell lifetimes of 3-5 years. Place a 0.1 uF ceramic decoupling capacitor within 5 mm of the VDD pin (pin 12) and an optional 10 uF bulk capacitor if VDD traces are long.
Reserve RA0 (pin 6) and RA1 (pin 5) for ICSP programming unless they are required for production operation - the ICSP lines share pins with these general-purpose I/Os and should be accessible to the programming header. RA3 (pin 3) is shared with /MCLR and must be pulled up to VDD via a 10 kohm resistor for normal operation; the /MCLR function is required only if the internal MCLR feature is disabled. Keep the ICSP connector footprint present even on production boards for field firmware updates.
Do not exceed 5.5 V on VDD - the PIC16F18323 has no internal overvoltage clamp and the absolute maximum rating of 6.5 V will damage the device. The configuration words must be programmed to enable the internal HFINTOSC and set the PLL off when 32 MHz is not required, otherwise the device can exceed the 32 MHz Fosc maximum at high VDD. For low-power designs, always disable the BOR feature only after confirming the supply is clean, because Bor-Brown assist can prevent undefined code execution during power-up.
