Key Features
- PIC16 8-bit core at up to 20 MHz with 1.75 KB Flash and 128 bytes RAM delivers simple control tasks in a 20-pin SSOP footprint with minimal PCB area
- 7-channel, 10-bit ADC enables direct connection to multiple analog sensors without external signal conditioning in battery-operated designs
- Integrated comparators and ECCP PWM module support closed-loop control applications such as fan speed and LED dimming at zero additional BOM cost
- Wide supply voltage range of 2.0 V to 5.5 V and nanoWatt XLP technology minimizes current consumption in coin-cell and energy-harvesting products
Applications
The PIC16F818-I/SS is used in low-cost consumer electronics, appliance controls, and sensor nodes where a compact 8-bit MCU with analog capability is needed under a tight BOM budget. Its 20-pin SSOP footprint suits space-constrained PCBs in smoke detectors, thermostat panels, and battery management modules. The device also serves as a co-processor in larger systems handling ADC sampling, PWM generation, or simple serial communication, offloading a main processor from routine analog tasks.

Frequently Asked Questions
How many analog input channels does the PIC16F818-I/SS support and at what resolution?
The PIC16F818-I/SS features a 7-channel, 10-bit ADC with a maximum sampling rate of approximately 50 ksps at 20 MHz clock. This resolution provides 1024 discrete levels across the supply rail, sufficient for reading temperature sensors, potentiometers, and light-dependent resistors in consumer and industrial sensing applications.
Can the PIC16F818-I/SS run from a 3.3 V supply in low-power IoT sensor designs?
Yes, the device operates from 2.0 V to 5.5 V, making it directly compatible with 3.3 V LDO regulators common in IoT sensor nodes. In Sleep mode with the watchdog timer enabled, current consumption drops below 1 µA, extending coin-cell battery life in intermittently-sampled data loggers and wireless sensor endpoints.
What PWM capability does the PIC16F818-I/SS provide for motor and lighting control?
The MCU includes an Enhanced CCP (ECCP) module capable of generating a 10-bit resolution PWM signal at frequencies determined by the 20 MHz clock and Timer2 prescaler. Typical PWM frequencies range from about 1.2 kHz to 20 kHz, covering LED dimming, small DC motor speed control, and power-supply duty-cycle adjustment.
How does the PIC16F818-I/SS compare to the PIC16F819 when evaluating memory requirements?
The PIC16F818-I/SS provides 1.75 KB of Flash program memory and 128 bytes of RAM, while the PIC16F819 doubles Flash to 3.5 KB. Designs with firmware exceeding 1 KB or requiring large lookup tables should migrate to the PIC16F819, which fits the same 20-pin SSOP footprint and is pin-compatible, enabling an easy upgrade path without PCB changes.
