PIC16LF1823-I/SL - 8-bit 32MHz XLP MCU 3.5KB Flash | Microchip
MPN: PIC16LF1823-I/SL ✓ فعالPIC16LF1823-I/SL جائزہ
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, Flash program memory, RAM, peripherals, and I/O onto one die, executing one instruction per cycle under a RISC architecture. The PIC16LF1823 sits within the PIC16 enhanced mid-range taxonomy: PIC16 -> mid-range 8-bit family -> PIC16F1xxx enhanced mid-range -> eXtreme Low Power (XLP) subset. The XLP designation indicates optimized sleep currents below 50 nA typical, making this part ideal for battery-powered IoT nodes, sensor peripherals, and remote controls where quiescent current dominates battery life.
Key features include the 32MHz internal oscillator (eliminating external crystals in many designs), 3.5KB Flash self-programmable memory, 128 bytes SRAM, 256 bytes EEPROM, an integrated 10-bit ADC, comparators, PWM modules, EUSART, and I2C/SPI. The XLP technology achieves sleep currents below 100 nA with retention, enabling multi-year coin-cell operation. The 14-pin SOIC package (SL suffix) provides hand-solder-friendly through-hole-compatible footprints and operates across the standard -40C to +85C industrial range, supporting consumer and industrial temperature applications.
The PIC16LF1823 uses a Harvard-architecture RISC core with a 14-bit instruction word and 200ns instruction execution at 20MHz, while the LF (low-voltage F) process variant extends operational efficiency at 1.8V-3.6V supply. Core-independent peripherals (CIPs) such as the Configurable Logic Cell (CLC), Numerically Controlled Oscillator (NCO), and Complementary Waveform Generator (CWG) offload tasks from the CPU, further reducing active-mode power consumption and enabling deterministic peripheral operation without waking the core.
Typical applications include battery-powered IoT sensor nodes, remote controls, low-power wireless peripherals, energy harvesting designs, wearable health monitors, smart metering, and consumer electronics with segmented LCD or LED interfaces. The compact 14-pin footprint suits space-constrained designs where PCB real estate is at a premium.
When designing with this part, ensure decoupling capacitors of at least 100nF are placed within 5mm of the VDD pin, and that unused I/O pins are configured as outputs to minimize shoot-through current. The LF process variant requires supply voltages strictly within 1.8V-3.6V (extended from 2.5V-3.6V typical); for designs targeting 5V operation, select the PIC16F1823 (standard F variant) instead.

The PIC16LF1823-I/SL serves smart metering endpoints like water, gas, and heat meters where XLP technology enables 10+ year battery operation on a single lithium cell. Its 10-bit ADC with internal voltage reference supports pulse counting and low-resolution sensor measurement, while EUSART enables AMR (Automatic Meter Reading) interfaces. Industrial -40C to +85C operation handles outdoor metering cabinet environments, and the 256-byte EEPROM retains calibration data and accumulated counts through battery replacement events.

ڈیزائن نوٹس
Estimated: For battery-life calculations on CR2032 (220mAh, 3V), at 50nA sleep current plus 1% active duty cycle at 1mA average active current, average current drain is approximately 10uA. Theoretical battery life: 220,000uAh / 10uA = 22,000 hours = 2.5 years. Real-world life is shorter due to coin-cell self-discharge and temperature effects. Disable WDT, brown-out detect in deep sleep, and use the CLC plus NCO to keep the CPU asleep while peripherals handle event detection.
Place a 100nF decoupling capacitor within 5mm of the VDD pin (Pin 1) and a 10uF bulk capacitor near the IC supply input. Connect VSS (Pin 14) directly to a ground plane with vias placed within 2mm. For ICSP programming header, route PGC/PGD (RA1/RA0) traces as short as possible and avoid running them parallel to switching signals. MCLR/RA5 should have a 10k pull-up to VDD for normal operation; if using external reset, route via a dedicated trace.
Configure all unused I/O pins as outputs with the output level set to the inverse of any nearby high-impedance trace to prevent floating-pin current draw (typically 1-5uA per floating pin). Disable unused peripherals via their control registers. For ADC accuracy, place analog signal traces away from switching signals, use a ground pour around analog pins, and use adequate settling time before sampling - the internal ADC requires at least 1.5 ADC clock cycles of acquisition time per the datasheet's ADC section.
The LF variant cannot operate above 3.6V - applying 5V to VDD will damage the part. Choose PIC16F1823 (standard F variant) for 5V designs. Do not assume that the 32MHz internal oscillator is accurate to +/- 1% over the full voltage and temperature range; for UART or USB timing, consider using a crystal or the 16MHz HFINTOSC mode. The LF1823's 1.8V minimum voltage operation requires the VREG configuration; if the datasheet indicates 'low-voltage programming' mode, ensure that the configuration word matches the intended supply voltage to avoid code-protection lockout.
