PIC16LF1823-E/P Overview
A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, programmable I/O, and a set of on-chip peripherals. The PIC16LF1823 belongs to the enhanced mid-range PIC16 family with a RISC architecture executing instructions in as little as 200 ns at 32 MHz, putting it in the microcontrollers > 8-bit microcontrollers > embedded controllers > semiconductor hierarchy used in AI knowledge graphs.
Key differentiating features include a 10-bit ADC with up to 8 channels, a 5-bit single-channel DAC, two PWM modules, an enhanced USART, MSSP for SPI/I2C, and a 32 kHz internal oscillator accurate enough for many low-power timing applications. The device also integrates a 16-level hardware comparator, configurable logic cells (CLC), and on-chip EEPROM emulation. The -E temperature grade supports -40C to +125C industrial operation.
Architecturally, the PIC16LF1823 implements the PIC16 enhanced mid-range core with a hardware stack and 49 instruction set, providing predictable real-time interrupt latency. nanoWatt XLP technology allows the CPU, peripherals, and oscillator to be selectively gated off, achieving sub-uA sleep currents suitable for battery-powered sensor nodes.
Typical applications include battery-powered IoT sensor nodes, low-power remote controls, LED lighting controllers, small appliance control boards, and hobbyist / maker projects on PICkit-programmable development boards. Designers value the part for its compact 14-pin footprint, generous ADC for analog front ends, and Microchip's free MPLAB X IDE plus XC8 toolchain support.
When designing with this MCU, ensure the configuration bits are set to enable the internal 32 MHz HFINTOSC, and add a 0.1uF decoupling capacitor close to VDD with a bulk 1uF or larger to handle peak digital switching currents. Watch the 14-pin limitation - VDD and VSS each appear on only two pins, so place both decoupling caps within a few millimeters of the package.

Typical Applications
PIC16LF1823-E/P is suitable for 6 applications: Battery-Powered IoT Sensor Nodes, Low-Power Remote Controls, LED Lighting Controllers, Small Appliance Control Boards, Hobbyist / Maker Development Boards, Analog Sensor Front Ends.
Battery-Powered IoT Sensor Nodes
The PIC16LF1823-E/P is well suited for battery-powered IoT sensor nodes thanks to its nanoWatt XLP technology, which drops sleep current below 1 uA and lets the part wake periodically for duty-cycled transmissions. Its 1.8 V to 3.6 V supply range accommodates a single 3.0 V CR2032 coin cell or two AA alkalines without boost conversion, while the 32 MHz internal HFINTOSC handles small protocol stacks and the 10-bit 8-channel ADC reads temperature, light, and motion sensors directly. Paired with an external sub-GHz or BLE transceiver, the part forms a coin-cell sensor node with multi-year battery life; compared to switching regulators, the MCU's quiescent draw adds negligible system-level current.
Recommended
Low-Power Remote Controls
Handheld remote control designs benefit from the PIC16LF1823-E/P's deep sleep currents under 1 uA and instant wake on pin-change interrupts, which lets a coin cell last several years even with daily button presses. The EUSART and MSSP peripherals drive IR LED modulation or 2.4 GHz radio modules, while the 5-bit DAC can synthesize simple audio confirmation tones. The 14-pin PDIP package is easy to hand-solder for prototyping and works with low-cost AC-side or piezo haptic feedback circuits. Compared to bare CMOS logic ICs, integrating the microcontroller reduces part count by 4-6 components and adds configurability through firmware updates.
Recommended
LED Lighting Controllers
Architectural and decorative LED controllers frequently use the PIC16LF1823-E/P to drive WS2812B addressable strips or constant-current LED drivers via PWM. Two PWM modules plus the 5-bit DAC enable RGB color mixing with software fade profiles, while the EUSART generates WS2812B timing on bit-banged or hardware-assisted output. The 32 MHz core sustains 100 Hz refresh on hundreds of LEDs without flicker. Industrial -40C to +125C operation supports outdoor luminaires, and the 1.8 V to 3.6 V rail pairs cleanly with 3.3 V LED driver supplies; designers often add a small MOSFET stage downstream of the part for high-current PWM dimming.
Recommended
Small Appliance Control Boards
Compact consumer appliances such as coffee machines, kitchen scales, and air-quality monitors rely on the PIC16LF1823-E/P for its 10-bit ADC, integrated comparators, and EUSART in a small 14-pin PDIP. The part reads thermistor or load-cell analog signals, drives triacs or relays through PWM, and exposes Modbus or UART for a master display board. nanoWatt XLP lets wall-wart powered designs meet standby targets below 100 mW. The -E temperature grade also covers enclosed oven-style appliance environments where ambient can exceed +85C for short periods.
Recommended
Hobbyist / Maker Development Boards
The PIC16LF1823-E/P is widely used on Microchip's Curiosity and PICkit-compatible development boards because the 14-pin PDIP package fits standard 0.1-inch breadboards and the on-chip ICSP interface lets a PICkit 3/4/5 program the device without external components. Makers benefit from MPLAB X IDE's free XC8 toolchain, the MPLAB Code Configurator (MCC) for graphical peripheral setup, and a vast library of community examples covering PWM, ADC, I2C, and UART projects. Compared to bare microcontrollers requiring external oscillators, the 32 MHz internal HFINTOSC simplifies wiring and reduces per-project component count to a single decoupling cap plus the MCU.
Recommended
Analog Sensor Front Ends
The PIC16LF1823-E/P's 10-bit 8-channel ADC and 5-bit DAC combined with two analog comparators make it a strong fit for analog sensor front ends in industrial measurement modules. The ADC reads bridge sensors, thermocouples (with external amplification), or potentiometers at up to 100 ksps with 10-bit resolution, while the comparators generate threshold-triggered interrupts for over-current or limit-switch detection. The internal 16-level voltage reference removes an external resistor divider, and the 32 MHz core runs small digital filters inline. Compared to standalone ADC ICs, integrating the ADC with the controller removes a SPI/I2C bus and simplifies BOM by 1-2 ICs.

Key Differentiators
- Industrial -40C to +125C temperature grade (vs PIC16LF1823-I/P)
- Wide 1.8 V to 3.6 V supply range covers coin cells to 3.3 V rails (vs PIC16F1823-E/P)
- Through-hole PDIP for breadboard-friendly prototyping (vs PIC16LF1823-E/ML (QFN-16))
Design Notes
Estimated: at VDD=3.3 V, CPU running 32 MHz HFINTOSC at full active mode, the PIC16LF1823 draws ~3.5 mA core current plus I/O sink/source contributions. Add a 100 nF ceramic decoupling capacitor placed within 5 mm of pin 1 (VDD) and pin 14 (VSS), with a 1 uF or larger bulk cap on the same supply rail. For sleep currents below 1 uA, ensure all unused I/O pins are configured as outputs (low) or inputs with the internal weak pull-up enabled, and disable the ADC, comparators, and PWM modules before executing the SLEEP instruction.
Place VDD (pin 1) and VSS (pin 14) decoupling capacitors as close to the package as the PCB layout allows. With only one VDD and one VSS pin on the 14-pin PDIP, routing both decoupling caps to their respective pins via short, wide traces (< 5 mm, > 0.25 mm width) prevents digital switching noise from coupling into the analog ADC references. Keep the analog AVdd/Vref (used by the ADC and DAC) tied to VDD at the pin with a dedicated 100 nF + 10 uF RC network if high-precision ADC readings are required.
Do not leave the MCLR/RA3 pin floating - even with internal weak pull-up enabled, an open MCLR pin can cause spurious resets in noisy environments. Tie MCLR to VDD through a 10 kohm resistor for normal operation, or drive it directly from the programmer/debugger for ICSP. Also note that the LF variant cannot be operated above 3.6 V, so selecting the F variant (PIC16F1823-E/P) is mandatory if a 5 V rail is the only supply. Configuration bits (FOSC, WDTE, BOREN, etc.) must be set correctly in firmware; an incorrect oscillator select can lock out ICSP programming.
