PIC16F18325T-I/ST Visão geral
An 8-bit microcontroller (MCU) is a small, self-contained computer on a single integrated circuit that integrates a CPU, non-volatile program memory, RAM, peripherals and I/O. In the system hierarchy it sits under microcontroller -> embedded controller -> computing element. The PIC16F18325T-I/ST belongs to the 8-bit MCU class, within the broader semiconductor and embedded processing taxonomy, and is optimized for low-power general-purpose designs.
Key features include a 10-bit ADC with computation, 5-bit DAC, two comparators, 10-bit PWM with complementary outputs and a 16-bit Numerically Controlled Oscillator (NCO) for high-resolution waveform generation. Peripheral Pin Select (PPS) allows flexible remapping of digital peripherals to any I/O pin, which simplifies PCB layout when port assignments must change late in the design. Core Independent Peripherals such as CLC, CWG, NCO and CCP operate without CPU intervention, lowering active-mode power and code size.
The device operates from 1.8 V to 5.5 V and consumes roughly 25 µA/MHz active at 3 V and below 30 nA in sleep with peripherals running from LFINTOSC. The functional-safety (FuSa) capable silicon supports Class B safety-library use and the TSSOP-14 footprint is friendly to hand-soldered prototypes and high-density boards alike.
Typical applications include low-power IoT sensor nodes, battery-powered home-automation switches, general-purpose consumer control panels, automotive interior lighting and aftermarket body controllers, small industrial sensor interfaces and LED lighting control. The wide voltage range and XLP sleep modes make it especially attractive where coin-cell or 2xAA lifetimes of multiple years are required.
For power sequencing, drive MCLR through the standard Microchip RC network and place a 100 nF decoupling capacitor within 2 mm of VDD. Ensure unused I/O pins are configured as outputs low or inputs with weak pull-ups, otherwise floating CMOS inputs can draw tens of microamps each and silently defeat the XLP sleep budget.

Aplicações típicas
PIC16F18325T-I/ST é adequado para 7 aplicaçãos: Battery-Powered IoT Sensor Node, General-Purpose Consumer Control Panel, Automotive Interior Lighting and Body Controller, Industrial Sensor Interface Module, LED Lighting and Signage Controller, Smart Home Switch and Sensor Hub, Handheld Test and Measurement Probe.
Battery-Powered IoT Sensor Node
The PIC16F18325T-I/ST is well matched to coin-cell or 2xAA IoT sensor nodes because its XLP technology delivers under 30 nA in sleep mode with peripherals running from LFINTOSC, and active current is roughly 25 uA/MHz at 3 V. The 14-bit CIPs such as CLC and NCO offload waveform generation so the CPU can stay asleep between samples, while PPS allows late-stage PCB reassignment of UART/SPI/I2C pins. With 14 KB Flash and 1 KB SRAM the device can host a small state-machine or lightweight sensor stack; data EEPROM preserves calibration across battery swaps. A typical implementation drives a 2xAA supply and sleeps >99% of the time, achieving multi-year node lifetime on a CR2032.
Recomendado
General-Purpose Consumer Control Panel
For consumer keypads, IR remotes and small appliance controllers the PIC16F18325T-I/ST offers 1.8-5.5 V operation, 10-bit ADC for potentiometer and battery-voltage sensing, plus CWG for half-bridge IR modulation. The 5-bit DAC supports simple audio-tone feedback without an external amplifier, and EUSART plus SPI/I2C give plenty of headroom for display or radio daughter boards. PPS helps layout when switch-matrix pinouts are revised late. The TSSOP-14 footprint fits sub-50 mm² panels while remaining friendly to hand rework during prototype bring-up.
Recomendado
Automotive Interior Lighting and Body Controller
Automotive RGB ambient lighting and small body controllers benefit from the PIC16F18325T-I/ST 10-bit PWM with complementary outputs for high-side/low-side LED drive, the NCO for smooth dimming ramps and Functional-Safety (FuSa) Class B library for diagnostics. While this -I grade is industrial temperature, the family offers -E automotive equivalents on the same die. The 5-bit DAC can drive thermistor biasing, and the EUSART handles LIN-style single-wire UART traffic. Wide 1.8-5.5 V supply tolerates automotive load-dump events with adequate bulk capacitance.
Recomendado
Industrial Sensor Interface Module
Industrial 4-20 mA loop-powered sensor interfaces use the PIC16F18325T-I/ST 10-bit ADC with computation for hardware-averaged readings, the two comparators for window-detect alarms, and CLC for glitch-free shutdown logic. The 256-byte EEPROM stores calibration coefficients per probe, and the 32 MHz CPU runs PID loops at sub-millisecond rates. PPS allows the UART, I2C or SPI to be rerouted between field wiring and the bus connector without board rework. The industrial -40 to +85 C operating range and 1.8-5.5 V supply cover typical 24 V loop-derived rails with linear regulation.
Recomendado
LED Lighting and Signage Controller
For WS2812-style addressable LED chains and small signage controllers the PIC16F18325T-I/ST provides a 10-bit PWM, CWG for timed reset frames, and NCO for precise refresh timing. The 32 MHz instruction cycle supports 800 kbps WS2812 bit-bang with no CPU stall, while PPS reassigns the PWM output to whichever pin faces the LED header. The 1.8-5.5 V range directly powers 5 V LED strings; a small LDO handles 3.3 V logic when the bus is 5 V. With 14 KB Flash the MCU can hold rainbow patterns, configuration UI, and OTA bootloader hooks.
Recomendado
Smart Home Switch and Sensor Hub
Zigbee/BLE/Z-Wave wall switches and door sensors pair well with the PIC16F18325T-I/ST because its XLP sleep current under 30 nA enables multi-year operation on CR2032 coin cells. The 10-bit ADC monitors push-button voltage dividers and battery level, the 5-bit DAC can drive a piezo buzzer for chime feedback, and CLC implements debouncing and pulse counting without CPU wakeups. PPS remaps UART to whichever header faces the radio module. The TSSOP-14 footprint fits inside standard 50 mm x 50 mm wall-switch enclosures with all passives on one side of the PCB.
Recomendado
Handheld Test and Measurement Probe
Handheld DMM probes and simple signal-injector tools use the PIC16F18325T-I/ST 10-bit ADC for voltage/current measurement, the EUSART for USB-UART passthrough, and CWG for fixed-duty tone generation. The 1 KB SRAM buffers waveform captures, and the 256-byte EEPROM stores probe calibration across factory rework. The 1.8-5.5 V supply accepts 5 V USB and 3 V coin-cell backups; PPS allows probe designers to swap header pins between revisions. Low TSSOP-14 height leaves room for a side LCD, and the industrial -40 to +85 C range survives bench environments.

Notas de projeto
Estimated: at VDD=3.3 V and CPU=32 MHz the PIC16F18325T-I/ST active current is roughly 25 uA/MHz, so worst-case active draw is about 0.8 mA plus any peripheral bias. Place a 100 nF decoupling capacitor within 2 mm of VDD (pin 14) and a 10 uF bulk capacitor on the same supply node. For deep-sleep IoT duty cycles use LFINTOSC and disable FVR; sleep current drops below 30 nA with RTC/WDT running, which is critical for multi-year coin-cell operation.
Keep the ICSP programming header trace from MCLR/RA3/VPP (pin 4) under 50 mm and avoid sharing it with high-current switching signals to prevent false programming entries. Route VSS (pin 7) to a wide ground pour and keep the decoupling cap return path short. The TSSOP-14 thermal pad is a single ground pin; consider stitching additional ground vias near the package to reduce return-path inductance for EUSART/SPI/I2C signal integrity.
Unused PIC16F18325T-I/ST pins must be configured explicitly as outputs low or as inputs with the internal weak pull-up enabled - floating CMOS inputs can draw tens of microamps each and silently defeat the XLP sleep budget. When migrating from PIC16F1823 firmware, verify code does not assume only 3.5 KB Flash; routines linked above 0x0E00 will fail. Finally, never pull MCLR below VSS; Microchip recommends a 10 kohm pull-up to VDD plus the standard 100 nF cap to VSS.
Use the PPS registers to route EUSART/SPI/I2C away from pins adjacent to MCLR (pin 4) and crystal I/O (pins 5-6) to minimize noise coupling during sleep-wake transitions. For 32 MHz operation the device expects HFINTOSC stability around +/-2%; if your design uses SPI above 4 MHz add a 100 ohm series resistor near the source pin. The 10-bit ADC is adequate for general sensing but for high-impedance sources use the dedicated FVR and averaging modes to avoid sample-and-hold droop.
