PIC16LF1823-E/SL - 8-Bit 32MHz XLP MCU 3.5KB Flash | Microchip
MPN: PIC16LF1823-E/SL ✓ Hoạt độngPIC16LF1823-E/SL Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and programmable peripherals. The PIC16F family belongs to the 8-bit microcontrollers category, which sits under microcontrollers > integrated circuits > semiconductors in the standard taxonomy. Within Microchip's portfolio, the PIC16F family is the workhorse enhanced mid-range line optimized for cost-effective embedded control in consumer, industrial, and automotive-edge applications.
Key differentiating features include 32 MHz internal oscillator operation, nanoWatt XLP sleep currents as low as 20 nA (typical), an integrated 8-channel 10-bit ADC, two 8-bit timers plus one 16-bit timer, enhanced PWM/SCCP/CCP capture modules, an EUSART, I2C/SPI, and an on-chip mTouch capacitive-sensing peripheral. The 'LF' prefix indicates the wide low-voltage operating range of 1.8 V to 3.6 V.
The device uses a 14-bit instruction word RISC architecture with a hardware stack and interrupt controller, providing deterministic real-time response. The E (extended) temperature grade supports -40C to +125C operation, suitable for industrial and automotive under-hood environments when used behind appropriate transient protection.
Typical applications include battery-powered IoT sensor nodes, low-power remote controls, consumer white-goods user interfaces, HVAC thermistor signal conditioning, small motor PWM control (fans, pumps), and LED lighting controllers where sleep current dominates battery life.
Design consideration: the SOIC-14 (SL) package is pin-compatible with several PIC12F/PIC16F 8-pin/14-pin variants, but pinout differences between PIC16LF1823 and PIC16LF1824/1825 families mean direct cross-substitution requires revalidating the PCB artwork. Always confirm the datasheet pinout before dropping in a PIC16F18xx variant.

Ứng dụng tiêu biểu
PIC16LF1823-E/SL phù hợp cho 6 Áp dụngs: Battery-Powered IoT Sensor Nodes, Low-Power Remote Controls, Consumer White-Goods User Interface, HVAC Thermistor Signal Conditioning, Small Motor PWM Control (Fans, Pumps), LED Lighting Controllers.
Battery-Powered IoT Sensor Nodes
The PIC16LF1823-E/SL fits battery-powered IoT sensor nodes because its nanoWatt XLP technology delivers ~20 nA typical sleep current, allowing the part to spend most of its duty cycle in deep sleep and wake only on interrupt or timer. The 1.8 V minimum supply connects directly to a single CR2032 coin cell or two-cell alkaline stack without boost converter overhead. The 10-bit ADC with up to 8 channels digitizes temperature, humidity, or analog sensor outputs at sample rates below 1 ksps; the EUSART/SPI/I2C peripherals allow a sub-GHz or BLE companion module to be polled only when a meaningful event is detected.

Low-Power Remote Controls
Remote controls for TV, set-top box, or smart-home bridges benefit from the PIC16LF1823-E/SL's nanoWatt XLP sleep current, which dominates battery life when the device is idle most of the day. The 32 MHz CPU handles IR or sub-GHz OOK/FSK modulation directly from PWM hardware, eliminating the need for an external modulator. The on-chip mTouch peripheral can implement capacitive touch buttons or sliders without adding a touch IC, while the wide 1.8 V to 3.6 V supply accommodates a single CR2032 or 2x AA cells with no LDO.

Consumer White-Goods User Interface
Consumer appliances like washing machines, dishwashers, and microwave ovens use the PIC16LF1823-E/SL as the user-interface MCU, driving 7-segment or LCD displays, capacitive touch keys, and LED indicators while the main appliance controller handles power. The mTouch peripheral reduces BOM by eliminating mechanical buttons. The 12 I/O pins in the SOIC-14 footprint drive up to 12 LEDs or sense 12 capacitive pads. The Extended -40C to +125C temperature grade supports under-cabinet and behind-panel mounting near heat sources.

HVAC Thermistor Signal Conditioning
In HVAC and thermostat applications, the PIC16LF1823-E/SL digitizes NTC thermistor networks through its 10-bit ADC and runs the PID loop that drives a relay, TRIAC, or 0-10 V actuator. The wide 1.8 V to 3.6 V supply tolerates sensor bridge voltage variations without regulation, while nanoWatt XLP keeps standby power below the 1 W EU Ecodesign limit for thermostats. The CCP/ECCP/PWM modules generate a hardware-accurate PID output without CPU intervention, freeing the core for HMI and connectivity tasks.
Được đề xuất
Small Motor PWM Control (Fans, Pumps)
The PIC16LF1823-E/SL controls small DC fans, water pumps, and solenoid valves via hardware PWM, with the enhanced CCP module providing complementary outputs and configurable dead-band for half-bridge drivers. The 32 MHz clock gives 8-bit PWM at 125 kHz with 7-bit effective resolution at the typical 31 kHz carrier - sufficient for low-inductance fan motors. The fault-input and PWM shutdown features protect downstream MOSFETs in over-current conditions without CPU latency.
Được đề xuất
LED Lighting Controllers
LED drivers and dimmer controllers use the PIC16LF1823-E/SL to manage dimming curves, color mixing in RGBW fixtures, and DALI or 0-10 V dimming interfaces. The PWM modules provide 16-bit resolution at low dimming ratios without software bit-banging, while the 10-bit ADC reads photocells and temperature sensors for closed-loop lumen maintenance. The 32 MHz CPU supports DALI-2 frame encoding/decoding within protocol timing budgets without an external transceiver.

Ghi chú thiết kế
Estimated sleep current budget: at 3.3 V VDD with WDT disabled and no peripheral clocks running, the PIC16LF1823 draws approximately 20 nA typical per the nanoWatt XLP specification. A CR2032 coin cell (220 mAh nominal) can therefore sustain 9+ years of duty-cycled sleep if the active-mode current is bounded. Always disable unused peripherals (ADC, BOR, EUSART) via the corresponding PMDx/PMD registers to avoid parasitic current draw; leaving them clocked can add 50 to 500 uA. The SLP and SLPWAK registers control retention state on wake - misconfiguring SLP bits is the most common cause of unexplained 'stuck' current draw.
At 32 MHz active and full peripheral load, the PIC16LF1823-E/SL draws approximately 4 mA at 3.3 V (~13 mW), far below any thermal-stress concern in the SOIC-14 package (theta_JA around 70 C/W). Junction temperature rise above ambient is therefore <1 C under any realistic load - thermal management is not required. The Extended -40C to +125C temperature grade ensures the silicon itself is reliable across automotive under-hood environments when used behind appropriate supply transient protection (TVS diode at VDD).
Place a 100 nF decoupling capacitor within 5 mm of the VDD pin (pin 14), and a bulk 4.7 uF capacitor on the same net if the supply source is more than 25 mm away. For ADC accuracy, route AVSS to a clean ground island or star-ground back to the main GND at a single point - do not share analog ground return paths with high-current digital loads. The mTouch capacitive-sensing peripheral is sensitive to adjacent ground pours; route a ground-free keep-out of at least 2 mm around CPS pins used as touch electrodes to prevent false triggering.
Common pitfalls: (1) Selecting the wrong oscillator mode and finding that the LFINTOSC drifts more than 1% over temperature - use the HFINTOSC with PLL for timing-sensitive UART baud rates. (2) Forgetting to configure the PPS (peripheral pin select) registers when remapping EUSART/SPI pins - the PPS defaults may not match your schematic. (3) Programming the flash with the wrong configuration-word settings, especially WDTEN and BOREN, which can disable UART debug or cause spurious resets. (4) Confusing the LF (1.8-3.6 V) part number with the F (1.8-5.5 V) variant and seeing undervoltage lockout above 3.6 V on the LF device.
