Product details
Overview
PIC16LF18325-I/ST from Microchip Technology is an eXtreme Low Power (XLP) 8-bit microcontroller in 14-pin TSSOP package, featuring 14 KB Flash, 1 KB SRAM, 10-bit ADC with 11 channels, dual comparators, and four CCP modules. It operates from 1.8V to 3.6V at -40°C to +85°C and supports PWM, CWG, CLC, NCO, and EUSART for battery-powered sensor nodes and smart peripherals.
For engineers reviewing the PIC16LF18325-I/ST datasheet, PIC16LF18325-I/ST pinout, PIC16LF18325-I/ST application, or PIC16LF18325-I/ST equivalent, this page delivers verified electrical specs, validated peripheral mapping, confirmed low-power operating modes (40 nA sleep), and real-world use cases in energy-constrained embedded control systems.
Technical Context
The PIC16LF18325-I/ST implements a RISC CPU core with 48 instructions, 125 ns instruction cycle at 32 MHz, and 16-level hardware stack. Its Peripheral Pin Select (PPS) enables full remapping of digital peripherals-including four CCPs, two CWGs, and dual MSSP modules-to any I/O pin, decoupling logic design from physical layout constraints.
It integrates analog resources including a 10-bit ADC with 11 external inputs, 5-bit DAC with rail-to-rail output, fixed voltage reference (1.024V/2.048V/4.096V), and two comparators with internal references-enabling closed-loop analog signal conditioning without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PIC16F18325-I/ST | Higher 2.3–5.5V operating range; no LPBOR option; identical peripherals and pinout. | Preferred where higher supply voltage simplifies power architecture (e.g., 3.3V or 5V systems). | Select when system voltage exceeds 3.6V and XLP sleep current is not critical. |
| PIC16LF18324-I/ST | 7 KB Flash, 512B SRAM, 12 I/O, same XLP specs; lacks one CCP and one CWG module. | Suitable for simpler control tasks with reduced peripheral demand (e.g., basic timer + ADC only). | Choose when firmware size < 7 KB and dual CWG/4x CCP are unnecessary-lowers cost without sacrificing XLP performance. |
Compared with PIC16LF18325-I/ST, PIC16F18325-I/ST trades ultra-low sleep current for wider voltage tolerance, while PIC16LF18324-I/ST reduces memory and peripheral count to meet cost-sensitive, lower-complexity designs-both retain PPS, CLC, and NCO functionality.

FAQ
What is the maximum operating frequency of the PIC16LF18325-I/ST?
The PIC16LF18325-I/ST supports up to 32 MHz system clock input with a minimum instruction cycle time of 125 ns. Its internal oscillator is factory-calibrated to ±2% at 4 MHz, and it includes a 4× PLL for higher-frequency operation when driven by external sources. This allows real-time execution of time-critical firmware on the PIC16LF18325-I/ST without external clock components.
Does the PIC16LF18325-I/ST support in-circuit debugging?
Yes, the PIC16LF18325-I/ST supports full in-circuit debugging via two dedicated pins: RA0/ICSPDAT and RA1/ICSPCLK. These pins provide bidirectional communication with Microchip's MPLAB® ICD 4 or PICkit™ 4 debuggers, enabling breakpoints, register inspection, and live variable monitoring during development-all without requiring additional hardware interfaces on the PIC16LF18325-I/ST.
How many analog input channels does the PIC16LF18325-I/ST ADC support?
The PIC16LF18325-I/ST features a 10-bit ADC with 11 external analog input channels (ANA0–ANA5, ANC0–ANC5), plus internal temperature indicator and VDD monitoring. Channel selection is software-controlled, and conversions can be triggered automatically during Sleep mode-enabling accurate, low-power sensor polling on the PIC16LF18325-I/ST.
Can the PIC16LF18325-I/ST generate complementary PWM waveforms with dead time?
Yes, the PIC16LF18325-I/ST includes two Complementary Waveform Generators (CWG1 and CWG2), each supporting rising/falling edge dead-band control, full-bridge/half-bridge drive modes, and multiple input sources. This allows safe, synchronized gate driving for BLDC motors or power converters directly on the PIC16LF18325-I/ST-no external dead-time IC required.
Is the PIC16LF18325-I/ST pin-compatible with other devices in the PIC16(L)F183XX family?
The PIC16LF18325-I/ST in 14-pin TSSOP shares identical pinout and electrical characteristics with PIC16F18325-I/ST and PIC16LF18324-I/ST in the same package. However, peripheral availability differs: PIC16LF18325-I/ST offers four CCP modules and two CWGs, whereas PIC16LF18324-I/ST has three CCPs and one CWG-firmware must verify peripheral enablement before substitution.
