PIC16F18425-I/JQ 概要
An 8-bit microcontroller (MCU) is a single-chip processor that integrates a CPU, non-volatile program memory (Flash), volatile working memory (RAM), and peripheral interfaces on a single die. Within the broader semiconductor taxonomy, an 8-bit MCU sits below 32-bit Cortex-M MCUs in computational throughput but excels in deterministic interrupt response, low power consumption, and BOM cost. The PIC16F18425 belongs to the eXtreme Low Power (XLP) family, optimized for battery-powered and energy-harvesting applications.
Key features include a 12-bit Analog-to-Digital Converter with Computation (ADCC), a 5-bit DAC, two PWM modules, a Comparator, Complementary Waveform Generator (CWG), EUSART, SPI, and I2C interfaces. The on-chip Core Independent Peripherals (CIPs) handle tasks such as signal conditioning and waveform generation without CPU intervention, reducing firmware complexity and power consumption. Operating voltage spans 1.8 V to 3.6 V (L-suffix variant) or 2.3 V to 5.5 V (F-suffix variant), with sleep current below 50 nA typical.
Architecturally, the PIC16F18425 uses a 14-bit instruction word RISC core with hardware stack and Peripheral Pin Select (PPS) for flexible pin mapping. The CWG peripheral can synthesize complementary PWM outputs with programmable dead-band for half-bridge driver control, eliminating external timing components in motor-drive and Class-D audio front-ends.
Typical applications include IoT sensor nodes, battery-powered wearables, low-cost motor control (fans, pumps, small BLDCs), LED lighting controllers, and consumer appliances. Its 1 KB RAM and 14 KB Flash are well matched to protocols such as LIN, Modbus RTU, and SMBus slave stacks.
Design tip: route the exposed pad (EP) to a continuous ground copper pour with multiple thermal vias to achieve the rated thermal performance; floating EPs degrade ADC accuracy and long-term reliability in high-vibration environments.

設計ノート
The UQFN-16-EP exposed pad must be soldered to a continuous ground copper pour with at least 4 thermal vias (0.3 mm drill, 0.5 mm pitch) to the inner ground plane. Floating the EP degrades thermal performance, increases ADC noise, and risks long-term reliability failures. Per Microchip UQFN package guidelines, keep digital traces away from the EP perimeter to maintain creepage clearance.
Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 16) and a bulk 1 uF to 10 uF capacitor on the same net. The PIC16F18425 has multiple VDD/VSS pin pairs internally bussed - a single decoupling pair at the IC is sufficient for most designs. For ADC accuracy, add a small ferrite bead or 10 ohm resistor between the digital VDD and analog AVDD rail if used.
PPS (Peripheral Pin Select) allows digital peripherals to be remapped, but analog functions remain fixed to specific pins. Do not assign PPS outputs to pins that share analog channels you plan to use simultaneously - the analog mux wins. Always lock the PPS configuration after final firmware tuning using the IOL1WAY configuration bit to prevent runaway reconfiguration at runtime.
When using the CWG peripheral for high-frequency switching (above 100 kHz), keep the CWG output traces short and away from the ADC input traces to avoid switching-noise coupling. Route complementary CWG outputs as a matched pair (length-matched within 5 mm) to maintain dead-band symmetry. Place a small RC snubber (10 ohm + 1 nF) on each output if ringing exceeds 10% of the rail.
Estimated: at maximum CPU activity (32 MHz, all peripherals active) the PIC16F18425 draws roughly 6 mA from 3.3 V, dissipating about 20 mW. With the UQFN-16-EP on a 1 square inch 2-oz copper ground pour, theta_JA is approximately 50 C/W, yielding a 1 C junction rise - well within rated limits. No heatsink is required for typical applications.
