PIC16F18325-I/P Descripción general
An 8-bit microcontroller (MCU) is a single-chip computer that integrates an 8-bit CPU core, program memory (Flash), data memory (RAM), non-volatile EEPROM, and a set of peripherals such as timers, ADC, and communication interfaces. PIC16F MCUs sit at the entry-level of Microchip's PIC16 enhanced mid-range family and are widely used as glue logic and control processors in industrial, IoT, and consumer applications. They sit at the bottom of the hierarchy: PIC16F18325 -> PIC16F family -> PIC microcontroller -> microcontroller -> embedded IC -> semiconductor.
Key features include Extreme Low Power (XLP) technology for battery-driven designs, Peripheral Pin Select (PPS) for flexible I/O mapping, Core Independent Peripherals (CIPs) such as Configurable Logic Cells (CLC), Numerically Controlled Oscillator (NCO), Complementary Waveform Generator (CWG), and Zero-Cross Detect. The device supports both 3V and 5V operation and is functional-safety ready.
The architecture uses an enhanced mid-range 8-bit CPU core with 49 instructions, a 16-level hardware stack, and interrupt capability with automatic context saving. Internal oscillator options and flexible clocking simplify BOM by eliminating external crystals in many designs.
Typical applications include low-power IoT sensor nodes, battery-powered home automation, automotive interior body modules, industrial control boards, and consumer white goods. The XLP features suit remote controls, energy harvesting, and wearables.
When designing with this MCU, ensure the configuration words are correctly programmed for the chosen oscillator and watchdog. PPS remapping must be configured before enabling peripherals. Decoupling capacitors of 100nF should be placed close to VDD.

Aplicaciones típicas
PIC16F18325-I/P es adecuado para 6 aplicacións: Low-Power IoT Sensor Node, Battery-Powered Home Automation, Industrial Control Board, Automotive Interior Body Module, Consumer White Goods, Remote Control and IR Toy.
Low-Power IoT Sensor Node
The PIC16F18325-I/P suits battery-powered IoT sensor nodes because of its Extreme Low Power (XLP) technology with sleep currents in the microamp range. Its 32MHz CPU and 14KB Flash handle sensor reading, basic edge processing, and BLE/UART comms with the host gateway. The integrated 10-bit ADC captures analog sensor data directly, while the 5-bit DAC drives reference outputs. At 3V operation with most time spent in sleep, a coin cell can power the node for years. The 14-pin PDIP package simplifies breadboard prototyping before SMD migration.

Notas de diseño
The PIC16F18325-I/P supports operating voltages from 2.3V to 5.5V per the Microchip datasheet (40001795E). Decouple VDD with a 100nF ceramic capacitor placed within 2-3mm of the VDD pin, and add a bulk 10uF capacitor near the supply rail. Enable the Brown-Out Reset (BOR) via configuration words to protect against low-voltage corruption during Flash programming.
Route the ICSP clock or ICSP data signals (RA1 and RA0 by default) away from high-current switching traces to avoid programming glitches. Place the MCLR pull-up (typically 10k ohm) close to pin 4. For PPS designs, document the pin mapping in code comments to ease rework when changing packages.
Do not forget to configure unused I/O pins as outputs and tied low, or set them as inputs with the WPU disabled, to minimize sleep current. When migrating from PIC16F1825-I/P, the PPS module requires explicit unlocking sequence (PPSLOCK bit) before remapping. Configuration words must be set correctly before code can execute; verify them in MPLAB X.
Estimated: At maximum CPU activity (32 MHz, 5V, all peripherals active), the PIC16F18325-I/P draws approximately 6-8 mA, dissipating 30-40 mW. The PDIP-14 package has adequate thermal dissipation for normal operation; no heatsink is needed. In sleep mode with XLP, total current drops to under 1 uA per datasheet.
