PIC16F1823-E/SL Visão geral
A microcontroller (MCU) is a compact integrated computer-on-a-chip that combines a CPU core, non-volatile program memory, working RAM, and programmable I/O peripherals. Within the broader taxonomy, a microcontroller sits between microprocessors and ASICs: more capable than a fixed-function ASIC, more integrated than a microprocessor that requires external memory. The PIC16F1823 belongs to the 8-bit PIC16 enhanced mid-range family, which itself is a sub-family of Microchip's PIC (Peripheral Interface Controller) RISC architecture. MCUs are the building blocks of embedded systems, converting sensor inputs and user actions into deterministic outputs that drive displays, motors, communication links, and actuators.
Key features of the PIC16F1823 include nanoWatt XLP extreme low-power technology with sleep currents in the nano-audible/nanow-att range, a 10-bit ADC with up to 12 channels, multiple PWM modules, enhanced USART, MSSP (I2C/SPI), and 12 I/O pins. The device also integrates an internal 32 MHz oscillator and a 31 kHz low-power oscillator for flexible clock management. The on-chip 256-byte EEPROM is byte-writeable and supports >100k erase/write cycles, while the flash program memory supports >10k erase/write cycles for in-application re-programmability.
Architecturally, the PIC16F1823 uses a Harvard RISC design with a 14-bit instruction word and a deep interrupt stack, achieving predictable deterministic execution. The enhanced mid-range core adds hardware CWG, NCO, DSM and other peripherals that are not present on baseline PIC16 devices, making the part well suited for switched-mode and precision-timing applications.
Typical applications include ultra-low-power IoT sensor nodes, battery-powered consumer products, LED lighting controls, automotive body and interior subsystems, industrial sensor interfaces, and small appliance control panels. The 12 available I/O pins support direct LED drive, keypad scanning and segment LCD signaling without external glue logic.
When designing with the PIC16F1823-E/SL, verify decoupling (100 nF close to VDD, plus bulk cap) and ensure the ICSP programming pins (PGD/PGC) are accessible for production programming and field updates. The 'E' temperature grade (-40C to +125C) makes this specific variant the right choice for industrial and automotive-grade designs, while the 'I' grade (-40C to +85C) is suitable for commercial environments.

Aplicações típicas
PIC16F1823-E/SL é adequado para 7 aplicaçãos: Ultra-Low-Power IoT Sensor Nodes, Automotive Body and Interior Electronics, LED Lighting and Signage Drivers, Industrial Sensor Interface and Signal Conditioning, Small Appliance and Consumer Control Panels, Battery Charger and Power Management Front-ends, Hobbyist and Maker Embedded Projects.
Ultra-Low-Power IoT Sensor Nodes
The PIC16F1823-E/SL is purpose-built for battery-powered IoT sensor nodes thanks to its nanoWatt XLP architecture, which delivers sleep currents in the nano-ampere range while retaining 3.5 KB of flash and 128 B SRAM for sensor firmware. Its 12 I/O pins and 10-bit ADC handle temperature, humidity and motion sensor interfaces without external glue logic, and the integrated 32 MHz internal oscillator removes the need for an external crystal on space-constrained boards. Compared with a discrete MCU plus LDO solution, the integrated peripherals shrink BOM cost and PCB area by ~30%, which is decisive for coin-cell-powered deployments.
Recomendado
Automotive Body and Interior Electronics
The PIC16F1823-E/SL's -40C to +125C extended temperature range, 12 I/O, and EUSART/MSSP peripherals make it a strong fit for automotive body controllers, interior lighting, mirror adjust and seat-position modules. Its 10-bit ADC supports direct potentiometer and thermistor readout for analog feedback channels, while the multiple PWM outputs drive LED dimming and small DC motor control. AEC-Q100 is not formally listed on the part, so for safety-critical applications Microchip recommends a Q-graded PIC16 alternative or external supervision.
Recomendado
LED Lighting and Signage Drivers
LED lighting and signage products benefit from the PIC16F1823-E/S' multiple enhanced PWM outputs, 10-bit ADC for ambient-light sensing, and nanoWatt XLP sleep current for standby-mode energy compliance. The 14-SOIC footprint integrates cleanly into space-constrained linear and small-form-factor LED drivers, and the 256-byte EEPROM stores dim curves and color presets without an external memory device. Compared with a discrete 8-bit MCU plus external PWM IC, the integrated solution typically reduces BOM count by 4 to 5 components.
Recomendado
Industrial Sensor Interface and Signal Conditioning
Industrial sensor interfaces leverage the PIC16F1823-E/SL's extended -40C to +125C temperature grade, 10-bit ADC with up to 12 channels, and 2.5V-5.5V supply range to digitize analog signals directly from 4-20 mA loops, bridges, and thermocouples. Its EUSART and MSSP peripherals expose RS-232/485 and I2C/SPI buses for plant-floor gateways and PLCs, while the 12 I/O pins handle digital sensor enables and isolated outputs. The 14-SOIC footprint fits compact DIN-rail modules and field-mount transmitters.
Recomendado
Small Appliance and Consumer Control Panels
Small appliance control panels, including coffee machines, microwave keypads and washing-machine user interfaces, use the PIC16F1823-E/SL's 12 I/O pins to scan key matrices and drive segment displays directly. The 3.5 KB flash and 128 B SRAM handle UI state machines comfortably, and the internal 32 MHz oscillator eliminates the external crystal, reducing BOM cost and assembly yield risk. With a 1.8V minimum operating voltage, the part can also run from a single alkaline cell with step-up regulation.
Recomendado
Battery Charger and Power Management Front-ends
Battery charger front-ends for single-cell Li-ion, NiMH packs and coin cells use the PIC16F1823-E/SL's 10-bit ADC to monitor voltage and current, and its PWM outputs to drive synchronous rectifiers in switch-mode charger topologies. The 256-byte EEPROM stores charge profile parameters, while nanoWatt XLP standby current keeps quiescent drain below 50 nA in shelf mode, preserving battery shelf life. Compared with a hardware-only charger IC, the firmware-programmable PIC solution supports multiple battery chemistries on one PCB.
Recomendado
Hobbyist and Maker Embedded Projects
Hobbyists, students, and makers favor the PIC16F1823-E/SL because it pairs with Microchip's free MPLAB X IDE, XC8 compiler, and the low-cost PICkit programmer for under $30 total tool-chain cost. The 14-SOIC footprint fits standard 0.1-inch perfboard and breadboard adapters, while the 12 I/O and 10-bit ADC cover most beginner projects from blinking LEDs to line-following robots. With 3.5 KB flash and rich peripherals, the part scales from Blink-LED demos to full custom sensor platforms.

Notas de projeto
Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 1) of the PIC16F1823-E/SL, plus a 10 uF bulk capacitor on the same rail. For nanoWatt XLP sleep-mode designs, verify the chosen LDO or DC-DC regulator has a quiescent current below 1 uA, otherwise the regulator dominates sleep current and erases the benefit of the MCU's nano-amp sleep spec.
Route the ICSP pins (RA0/PGED and RA1/PGC) to test points or an in-circuit programming header so firmware updates are possible in production. The 14-SOIC package is 3.90 mm body width, so plan keep-out zones and clearance for the ICSP header to avoid layout rework if programming access is forgotten.
Do not configure the MCLR pin (RA3) as a general-purpose output without disabling the master-clear function in configuration bits, otherwise an external reset event can disable the MCU. Also, the PIC16F1823-E/SL is the -40C to +125C extended grade - if your design only needs -40C to +85C, the cheaper PIC16F1823-I/SL is a drop-in lower-cost alternative.
For designs that drive long cables or motor windings, add series resistors (typically 100 ohm) on PWM outputs and bulk capacitance on supply pins to limit switching transients. Estimated: at 32 MHz with 5V supply, switching edges reach sub-10 ns, which can couple into adjacent analog ADC traces - keep analog and digital traces physically separated and add a ground pour.
