PIC16F1823-I/JQ Overview
An 8-bit microcontroller (MCU) is a single-chip computer integrating a CPU, RAM, Flash program memory, peripherals and I/O on one silicon die. PIC16F devices occupy the mid-range tier of Microchip's 8-bit portfolio, sitting above baseline PIC10/12/14 parts and offering richer analog and communication peripherals. The PIC16F1823 specifically targets low-power applications through the eXtreme Low Power (XLP) technology family, which combines nanoWatt features, idle/doze modes and a low-power wake-up timer to extend battery life in portable products.
Key features include 12-channel 10-bit ADC, two 8-bit timers plus one 16-bit timer, enhanced PWM with up to 4 channels, hardware USART/MSSP (SPI/I2C), an internal 32 MHz oscillator and an operating voltage range of 1.8V to 5.5V. The 16-pin UQFN (JQ) package saves board area versus SOIC and PDIP equivalents, making the part attractive for space-constrained sensor and consumer designs.
The PIC16F1823 is built on Microchip's enhanced mid-range 8-bit core, providing C-compiler friendly architecture with linear memory map, hardware stack and interrupt priorities. On-chip peripherals are interconnected via the Peripheral Pin Select (PPS) module and supported by Core Independent Peripherals (CIPs) such as CWG, NCO and DSM, enabling complex functions without CPU intervention and reducing active current draw in battery-powered products.
Typical applications include IoT sensor nodes, battery-powered remote controls, consumer white goods front-panel controllers, low-cost motor control (small DC fans and BLDC drivers), LED lighting controllers and industrial sensor interfaces. The wide 1.8V-5.5V supply range allows direct connection to 2x AA alkaline, single-cell Li-Ion or USB-derived rails.
For reliable operation, place a 100 nF decoupling capacitor within 3 mm of the VDD pin, keep the MCLR pull-up below 47 kohm and route the ICSP programming signals away from switching nodes. Use MPLAB X IDE with the XC8 compiler for firmware development and the MPLAB Snap / PICkit 4 for in-circuit programming and debugging.

Typical Applications
PIC16F1823-I/JQ is suitable for 6 applications: Battery-Powered IoT Sensor Nodes, Consumer Remote Controls, Small DC Fan and BLDC Motor Control, LED Lighting Controllers, Industrial Sensor Interface Modules, Smart Appliance Front-Panel Controllers.
Battery-Powered IoT Sensor Nodes
The PIC16F1823-I/JQ is a strong fit for battery-powered IoT sensor nodes thanks to its nanoWatt XLP sleep current below 20 nA and fast wake-up from HFINTOSC. The 3.5 KB Flash, 128 B SRAM and 256 B EEPROM handle typical duty-cycled sensor read, transmit and sleep cycles without external memory. Placed on the same board with a sub-GHz or BLE radio and a 2x AA battery pack, the PIC16F1823-I/JQ can sustain 5+ year battery life in 1% duty-cycle sensor reporting applications. Designers should reserve pin RA0/RA1 for ADC sensor inputs and leverage the MSSP SPI port for the radio.
Recommended
Consumer Remote Controls
The PIC16F1823-I/JQ fits handheld consumer remote controls thanks to its 1.8V-5.5V supply range, internal 32 MHz oscillator (no crystal) and small UQFN-16 footprint. IR or RF transmission is generated with the enhanced PWM and EUSART, and key-press debounce uses the on-chip timers instead of external components. Powered by a single CR2032 coin cell with sleep current near 20 nA, a typical TV remote can run 5+ years on the same battery. Place decoupling within 3 mm of VDD and route the IR LED driver pin close to the package edge for shortest trace.
Recommended
Small DC Fan and BLDC Motor Control
The PIC16F1823-I/JQ is suitable for small DC fan or BLDC motor control where the 4-channel enhanced PWM, 10-bit ADC and fast interrupt response are required. The CIP-based CWG, NCO and DSM peripherals generate precise complementary PWM signals for sensorless BLDC commutation without CPU overhead, reducing active current and allowing longer sleep periods between torque updates. With A and B or A B Z Hall-sensor inputs, the PIC16F1823-I/JQ can implement closed-loop speed control in fans, pumps and small appliances. Designers should add back-EMF filtering on analog sense pins and 100 nF ceramic caps near each supply pin.
Recommended
LED Lighting Controllers
The PIC16F1823-I/JQ is well suited to digital LED lighting controllers because the enhanced PWM can drive WS2812B-style addressable strips via SPI/MSSP with minimal CPU load, while the 12-channel 10-bit ADC reads ambient light and color sensors for closed-loop brightness control. Sleep current below 20 nA makes the design usable in battery-powered decorative LED installations. The PIC16F1823-I/JQ's 3.5 KB Flash easily accommodates NeoPixel, APA102 and DMX protocols simultaneously, and its 1.8V-5.5V range supports direct Li-Po or USB-derived rails.
Recommended
Industrial Sensor Interface Modules
The PIC16F1823-I/JQ is appropriate for industrial sensor interface modules that convert analog signals into digital protocols over RS-485 or I2C. The 12-channel 10-bit ADC combined with the internal 1.024V fixed voltage reference (FVR) yields calibrated readings of bridge-type pressure sensors, RTDs and thermistors. The MSSP supports I2C slave for PLC field instrumentation, and the industrial -40 C to +85 C rating matches common factory environments. Use the EUSART with an external transceiver for RS-485 multi-drop networks up to 1 Mbps.
Recommended
Smart Appliance Front-Panel Controllers
The PIC16F1823-I/JQ is suitable for white-goods front-panel controllers where capacitive touch, LED indicators, and a UART link to the main MCU are required. The 12 I/O pins and 12-channel ADC support multiple capacitive sense pads via the on-chip Charge Time Measurement Unit (CTMU) and capacitive voltage divider (CVD), reducing BOM versus dedicated touch ICs. The EUSART links to the main appliance MCU, and the wide 1.8V-5.5V supply aligns with 3.3V or 5V appliance rails. Designers should reserve one timer interrupt for keypad scanning and use DMA-free polling during standby.

Key Differentiators
- Lowest-cost PIC16F1823 in the smallest package option (vs PIC16F1823-I/SL)
- Newer Core Independent Peripherals when migrating up (vs PIC16F18323-I/JQ)
- Extended temperature option available in the same footprint (vs PIC16F1823-E/JQ)
Design Notes
Place a 100 nF ceramic decoupling capacitor within 3 mm of the VDD pin (pin 8) and a bulk 10 uF aluminum-polymer or ceramic cap on the same rail. The PIC16F1823-I/JQ is rated for 1.8 V to 5.5 V operation; ensure that VDD rise time during power-up is monotonic and stays below the brown-out reset (BOR) trip threshold for the configured BOR setting. For battery applications, the XLP sleep mode reduces MCU consumption to under 20 nA typical, but peripheral leakage on I/O pins must be kept below 50 nA combined to preserve battery life.
The UQFN-16 (JQ) 4x4 mm package has an exposed thermal pad on the underside that should be soldered to a moderate copper pour on the top layer for mechanical reliability and thermal dissipation. Keep the ICSP programming signals (RB6 = ICSPCLK, RB7 = ICSPDAT) routed away from switching nodes and away from the MCLR pull-up resistor to avoid capacitive loading that prevents low-voltage ICSP. Maintain at least 0.2 mm clearance between the IC body and adjacent components to ease rework.
Configuration Word 1 must be programmed correctly for the chosen oscillator; selecting an external crystal without one present will lock out ICSP communication. The MCLR pin (RA3) requires a 47 kohm or smaller pull-up to VDD for proper reset operation, and leaving it floating may cause intermittent resets. Do not drive any I/O pin above VDD or below VSS - even small overvoltage stresses can trigger ESD latch-up on these small-geometry parts.
