- 32 MHz 8-bit PIC16 core with 14 KB flash and hardware DAC enables cost-effective analog signal generation without external components
- Operates from 2.3 V at 16 MHz and up to 5 V at 32 MHz, covering battery-powered and mains-derived power supply designs from a single device
- 28-pin SSOP package includes CWG (Complementary Waveform Generator) and multiple PWM channels for motor control and power-conversion applications
What is PIC16F18855-I/SS used for?
The PIC16F18855-I/SS is widely deployed in home appliances, industrial sensor nodes, and consumer products requiring cost-effective 8-bit control with integrated analog functions. Its on-chip ADC with computation, DAC, and CWG peripherals allow designers to implement closed-loop control for BLDC fans, heating elements, and lighting dimmer circuits without external analog ICs. The 28-pin SSOP footprint fits standard PC board layouts, and the broad 2.3 V to 5 V operating range simplifies power supply design across alkaline battery and regulated 3.3 V system rails.

Frequently Asked Questions
How does the PIC16F18855-I/SS Complementary Waveform Generator simplify half-bridge gate-drive circuit design?
The PIC16F18855-I/SS includes a hardware Complementary Waveform Generator that produces two out-of-phase PWM outputs with programmable dead-time insertion in 4 ns steps, eliminating the need for external gate-drive logic or dedicated dead-time controller ICs. This is directly usable in half-bridge or full-bridge motor-drive and DC-DC converter designs operating at switching frequencies up to 32 MHz clock divided by the PWM period, reducing BOM cost and PCB complexity in compact motor-control modules.
At what minimum supply voltage can the PIC16F18855-I/SS operate, and how does this affect battery-powered sensor designs?
The PIC16F18855-I/SS operates down to 2.3 V at 16 MHz, allowing direct operation from two series alkaline cells approximately 2.4 V to 3.2 V fresh without a boost regulator. This extends usable battery capacity compared to devices requiring a minimum 2.7 V or 3 V, and the device scales up to full 32 MHz performance at 5 V for mains-powered applications, giving designers a single-SKU solution across battery and line-powered product variants.
For a production run requiring both ADC signal acquisition and DAC reference generation, how many ADC channels and DAC outputs does the PIC16F18855-I/SS provide?
The PIC16F18855-I/SS integrates a 10-bit ADC with computation module supporting up to 24 input channels plus a hardware 5-bit DAC output, providing on-chip analog measurement and reference generation in a single 28-pin SSOP device. The ADC with computation module can perform hardware averaging, filtering, and threshold comparison, offloading significant signal-processing work from the 8-bit CPU and allowing the 14 KB flash to hold more application code rather than DSP routines.
