PIC16LF in PIC Microcontrollers Family
The PIC16LF family by Microchip Technology represents a specialized low-voltage branch of the 8-bit PIC16 architecture, optimized for extreme power efficiency. These microcontrollers are distinguished by their eXtreme Low-Power (XLP) technology, enabling operation at reduced voltage rails typically ranging from 1.8V to 3.6V. They are engineered for battery-dependent systems where minimizing sleep current and active power consumption is critical for extending operational longevity without sacrificing the flexibility of the mid-range PIC core and integrated peripherals.

| Part Number | RAM | Connectivity | I/O Pins | Package | ADC/DAC | Flash | Stock |
|---|---|---|---|---|---|---|---|
| PIC16LF1554-I/SL (Microchip Technology) | 256 x 8 | I2C, SPI, UART/USART | 11 | SOIC-14 | A/D 11x10b | 7KB | 548 |
| PIC16LF1823-I/ST (Microchip Technology) | 128 x 8 | I2C, LINbus, SPI, .. | 12 | TSSOP-14 | A/D 8x10b | 3.5K | 1,305 |
| PIC16LF18325-I/P (Microchip Technology) | 1K | I2C, LINbus, SPI, .. | 12 | DIP-14 | A/D 11x10b; D/A 1x5b | 14KB | 487 |
Variants within the PIC16LF family are primarily differentiated by their memory density, ranging from 3.5KB to 14KB of Flash, and their specific peripheral sets. Higher-end models like the PIC16LF18325 offer expanded I/O counts and more robust Core Independent Peripherals. Packaging options also vary significantly, from space-saving 14-pin TSSOP and SOIC footprints to traditional PDIP, allowing engineers to balance board real estate against manufacturing constraints.
