PIC16LF1847T-I/SS Overview
A microcontroller (MCU) is a single-chip computer that integrates CPU, memory, and peripherals. The PIC16 family is part of the 8-bit microcontroller category, sitting within the broader hierarchy of embedded microcontrollers -> microcontrollers -> integrated circuits -> semiconductors. The "LF" prefix designates low-voltage operation optimized for ultra-low power consumption, with nanoWatt XLP technology enabling sleep currents below 100 nA in deep sleep modes.
Key features include 1024 bytes RAM, 256 bytes EEPROM, up to 18 I/O pins, integrated mTouch capacitive touch sensing peripherals, 10-bit ADC with computation, multiple communication interfaces (I2C, SPI, EUSART), and configurable logic cells. The 20-pin SSOP (Small Shrink Small Outline Package) provides compact 5.30mm body width suitable for space-constrained PCB layouts. The industrial temperature grade (-40C to +85C) supports robust commercial and industrial deployment.
The PIC16LF1847T-I/SS utilizes a Harvard architecture RISC CPU with a 14-bit instruction word, achieving DC to 32 MHz operation with 125 ns instruction cycle. The enhanced mid-range core provides C compiler optimization with linear memory addressing up to 14KB for program and 1024 bytes for data, simplifying pointer-based firmware development.
Typical applications include capacitive touch user interfaces, low-power wireless sensor nodes, battery-powered IoT endpoints, consumer electronics with touch controls, industrial control modules, and portable medical devices. The XLP technology and mTouch integration reduce BOM cost by eliminating external touch ICs and power management components.
When designing with this MCU, ensure decoupling capacitors are placed close to VDD pins, and consider the SSOP-20 land pattern requirements. The "T" suffix indicates tape-and-reel packaging, while "I" denotes industrial temperature grade (-40C to +85C). For debugging, MPLAB tools support ICSP programming via PGD/PGC pins.

Key Differentiators
- Lowest voltage silicon for 3.3V-only battery systems (vs PIC16F1847T-I/SS)
- Tape-and-reel format for SMT assembly (vs PIC16LF1847-I/SS)
- 20-pin SSOP package for compact designs (vs PIC16LF1847T-I/SO)
Design Notes
Place a 100nF ceramic decoupling capacitor as close as possible to each VDD pin (pin 16) with the ground return to the nearest VSS pin (pin 15). For battery applications, add a 10uF bulk capacitor near the MCU to handle peak load transients from radio transmission or LED PWM. The nanoWatt XLP technology requires careful firmware design to enter Sleep mode during idle periods - avoid active peripherals that prevent deep sleep entry.
The 20-pin SSOP package has a 0.65mm pin pitch and 5.30mm body width. Maintain minimum trace width of 0.15mm and trace spacing of 0.15mm per IPC-2222 for the SSOP land pattern. Expose copper under the SSOP body to within 50% of the package footprint area to improve thermal dissipation. Keep high-speed digital traces away from analog ADC inputs to minimize crosstalk.
MCLR pin (pin 3) must be tied to VDD through a 10k ohm pull-up resistor for normal operation; do not leave it floating. The ICSP programming pins RB6/PGC (pin 13) and RB7/PGD (pin 14) are shared with general I/O - do not load these pins with strong pull-ups or pull-downs that exceed 4.7k ohm during programming. Verify device ID and revision in software to handle errata items documented in Microchip PIC16F/LF1847 errata sheets.
