What are the key features of PIC16F18855-E/SS?
- Core Independent Peripherals (CLC, NCO, PWM) execute control tasks autonomously without CPU intervention, reducing active current in event-driven designs
- Integrated 10-bit ADC and 5-bit DAC enable closed-loop analog control without external converter components
- 32 MHz internal oscillator with operation down to 2.3V at 16 MHz covers both 3.3V and 5V system architectures in a single 28-pin SSOP footprint
What is PIC16F18855-E/SS used for?
The PIC16F18855-E/SS targets industrial sensor interfaces, home-automation controllers, and motor-drive applications that require autonomous peripheral operation between CPU wakeup events. Its 14KB Flash and 256B EEPROM accommodate application code and non-volatile configuration storage for thermostat, PID controller, or data-logger firmware. The SSOP-28 package with 2.3V minimum supply suits space-constrained 3.3V battery-powered designs needing CIP-driven background sensor polling.

Frequently Asked Questions
How do Core Independent Peripherals (CIPs) in PIC16F18855-E/SS reduce power consumption in a periodic sensor-sampling application?
CIPs such as the CLC, NCO, and PWM in PIC16F18855-E/SS continue operating in Sleep mode without the CPU running, drawing less than 1µA in deep sleep versus 1–2mA active. A sensor wake-sample-sleep cycle using the hardware ADC auto-conversion trigger can sample all 10-bit ADC channels, store results in SRAM, and wake the CPU only when a threshold is crossed, cutting average current to under 50µA at 3.3V in a 1-sample-per-second duty cycle.
What is the non-volatile memory configuration of PIC16F18855-E/SS, and how can the 256B EEPROM be used in a thermostat application?
PIC16F18855-E/SS provides 14KB of self-write Flash, 1KB of SRAM, and 256 bytes of data EEPROM. In a thermostat design, the 256B EEPROM stores up to 128 two-byte set-point entries or a 64-entry schedule table that survives power outages. Byte-level EEPROM writes take approximately 2ms each, and the 10,000-cycle write endurance supports daily schedule updates for over 27 years of continuous operation.
For a 3.3V motor-control PCB, how many PWM outputs does PIC16F18855-E/SS provide and at what resolution?
PIC16F18855-E/SS provides up to 4 independent PWM channels with 10-bit resolution at up to 31 kHz switching frequency when running at 32 MHz. For a 3.3V brushless DC motor controller, two complementary PWM pairs can drive a half-bridge gate driver directly, with 10-bit duty-cycle resolution giving 1024 speed steps between 0% and 100% without additional hardware. The CLC block can also generate hardware dead-time insertion between complementary outputs.
When should PIC16F18855-E/SS be chosen over PIC16F18854 for a new design?
Choose PIC16F18855-E/SS (28-pin SSOP) over PIC16F18854 (20-pin SOIC) when your design needs more than 16 GPIO pins, more ADC input channels, or additional communication peripherals. PIC16F18855 provides up to 25 GPIO pins versus 17 for PIC16F18854, and doubles the available I2C and SPI peripheral instances, supporting multi-sensor I2C buses with up to 8 addressable devices while maintaining the same 32 MHz maximum clock and 14KB Flash capacity.
