What are the key features of PIC16F1847-I/SO?
- 8-bit PIC16 core at up to 32 MHz with 14 KB Flash supports sophisticated firmware in a compact 18-pin SOIC-18 form factor for space-constrained designs
- Integrated ADC enables direct analogue sensor input reading without an external converter, reducing BOM cost and PCB complexity
- Low-voltage operation down to 1.8 V at 16 MHz makes PIC16F1847 suitable for single-cell lithium or alkaline battery-powered applications
What is PIC16F1847-I/SO used for?
PIC16F1847-I/SO is a versatile 8-bit microcontroller suited for battery-powered consumer electronics, home automation sensors, and small appliance controllers where 14 KB Flash and 18 I/O pins are sufficient. Its 1.8 V minimum supply at 16 MHz qualifies it for single-cell lithium-ion or 2-cell alkaline-powered designs with tight power budgets. The 18-pin SOIC package and integrated ADC reduce BOM complexity in compact sensor nodes for temperature monitoring, motor control, and display driving.

Frequently Asked Questions
What is the minimum supply voltage for PIC16F1847-I/SO, and which battery configurations does it support directly?
PIC16F1847-I/SO operates from a minimum of 1.8 V at 16 MHz. This allows direct operation from a single-cell lithium-ion battery (3.7 V nominal, discharged to 3.0 V) without a boost regulator, and from a 2-cell alkaline pack (3 V nominal, discharged to 1.8 V) for the full discharge curve. Removing the boost regulator saves board space and eliminates a switching converter's EMI.
How much Flash does PIC16F1847-I/SO provide, and is that enough for a bootloader plus application firmware?
PIC16F1847-I/SO contains 14 KB of Flash program memory. A typical PIC bootloader occupies 2 KB to 4 KB, leaving 10 KB to 12 KB for application code—sufficient for sensor read-process-transmit loops, simple state machines, and protocol handlers. If more than 12 KB of application code is needed, the PIC16F1847's larger sibling with 28 KB would be the next step up.
What ADC resolution and channel count does PIC16F1847-I/SO provide for analogue sensor interfacing?
PIC16F1847-I/SO integrates a 10-bit ADC with multiple multiplexed input channels, resolving voltages to approximately 4.9 mV per LSB at a 5 V reference or 1.8 mV per LSB at a 1.8 V reference. This precision handles temperature sensors outputting 10 mV/°C, resistive voltage dividers for battery monitoring, and light-dependent resistors in ambient light control circuits without external signal conditioning.
How does PIC16F1847-I/SO in SOIC-18 compare to a DIP-18 variant for PCB production and prototyping?
The SOIC-18 package has a body roughly 11 mm × 7 mm with 1.27 mm pin pitch, consuming significantly less PCB area than an 18-pin DIP (25 mm × 6 mm with 2.54 mm pitch). SOIC is compatible with standard SMT pick-and-place assembly, reducing labor cost in volume production. A DIP-18 variant is easier for breadboard prototyping, but once firmware is validated, SOIC-18 is the preferred form factor for board-level manufacturing.
Which serial communication peripherals does PIC16F1847-I/SO include for connecting to external sensors or host processors?
PIC16F1847-I/SO integrates at least one MSSP (Master Synchronous Serial Port) supporting both SPI and I2C modes, plus a UART/EUSART for asynchronous communication at baud rates up to 1 Mbps at 32 MHz. This allows the MCU to simultaneously manage a 400 kHz I2C temperature sensor, an SPI display driver, and a 115,200 baud debug console without requiring external level shifters at 3.3 V operation.
