PIC16LF18856-E/SP - 32MHz 8-bit XLP MCU, 28KB Flash | Microchip
The Microchip Technology PIC16LF18856-E/SP is an 8-bit PIC16F-family microcontroller built on the eXtreme Low Power (XLP) architecture, delivering 32 MHz CPU performance, 28 KB (16K × 14) of Flash program memory, 2 KB of RAM, and 256 bytes of EEPROM in a 28-pin SPDIP (Skinny Plastic DIP, 0.300"/7.62 mm) through-hole package.
What is a PIC16 microcontroller? The PIC16F family is Microchip's mid-range 8-bit MCU line built around a modified Harvard architecture and a 14-bit instruction word. Members of the PIC16LF1885x/7x family combine analog peripherals, core-independent peripherals (CIPs) such as CRC/SCAN, and XLP technology for battery-powered and general-purpose applications. PIC16LF variants run from a 1.8V to 3.6V supply, while PIC16F variants run from a wider range, making the LF parts the lowest-power members of the family.
Key features include 28 KB self-programmable Flash, 2 KB SRAM, 256 B EEPROM, a 10-bit ADC with computation, a 5-bit and 10-bit DAC, comparators, PWM, Complementary Waveform Generator (CWG), Signal Measurement Timer (SMT), Hardware Limit Timer (HLT), Windowed Watchdog Timer (WWDT), SCAN/CRC, Zero-Cross Detection (ZCD), Peripheral Pin Select (PPS), one EUSART, two SPI/I²C, and eXtreme Low-Power (XLP) sleep modes. The wide operating voltage (1.8V to 3.6V) and nanoWatt XLP sleep current make this part suitable for battery-powered sensor nodes.
Technically, the part implements CIP blocks that allow timing-critical events to run without waking the CPU, including the CWG for half-bridge motor drive waveforms, SMT for precise capture/measurement, and PPS for flexible signal routing. The integrated 10-bit ADC with ADC2 computation offloads averaging and threshold detection from the core, freeing MIPS for the main application loop.
Typical applications include low-power IoT sensor nodes, battery-powered metering, consumer electronics, LED lighting control, motor control signal generation (BLDC/PMSM commutation assist), and general-purpose embedded control replacing larger 16-bit parts. The 28-pin SPDIP package is particularly convenient for breadboard prototyping, hobbyist designs, and through-hole production lines where SMD reflow is unavailable.
When designing with this part, plan oscillator and configuration bits early: PPS must be unlocked before any peripheral remap, the ADC requires T_AD setup time, and the WDT must be configured before enabling code protection. Use Microchip's MPLAB X IDE with XC8 compiler and MPLAB Code Configurator (MCC) for rapid peripheral setup.
