PIC16LF18325T-I/ST Übersicht
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), working memory (RAM), data EEPROM, and a rich set of peripherals onto one silicon die. PIC microcontrollers in the PIC16 family use a RISC-based Harvard architecture with a 14-bit instruction word optimized for deterministic, low-power embedded control, sitting one tier above traditional 8051 devices in code density and peripheral integration for cost-sensitive designs. PIC16 LF variants specifically target battery-friendly operation from sub-2V rails.
Key features of the PIC16LF18325T-I/ST include extreme low-power XLP technology with typical sub-1 uA sleep current, 4 x 10-bit PWM outputs, 2 CCP modules, EUSART, SPI, and I2C peripherals with Peripheral Pin Select (PPS) that allows remapping of digital peripherals to any I/O pin. The device supports up to 12 ADC channels and provides 12 MIPS performance from a 48MHz internal oscillator block. PPS removes the constraint of fixed peripheral-to-pin assignments common in older PIC16 parts.
Architecturally, the PIC16LF18325 uses Microchip's enhanced mid-range 14-bit core with a hardware multiplier, 16-level hardware stack, and nanoWatt XLP technology that enables battery lifetimes of years in sensor and IoT applications. The ADC2 block performs automated averaging, burst averaging, and threshold comparison in hardware, freeing the CPU for other tasks. The 5-bit DAC, comparators, and CLC together provide configurable analog-front-end functionality without external components.
Typical applications include battery-powered IoT sensor nodes, consumer remote controls, automotive body electronics sub-modules, low-cost motor control using the CWG/NCO pair, general-purpose digital power supply housekeeping, and small appliances. Its 1.8V minimum supply also enables direct operation from single-cell lithium or two AA alkaline cells.
When designing with this part, ensure your programmer/debugger is an MPLAB PICkit, ICD, or Snap compatible toolchain. Decouple VDD with a 100nF ceramic capacitor placed within 5mm of the pin, and configure unused I/O as outputs driven low rather than floating inputs to minimize current draw. The 'I' temperature grade supports -40C to +85C industrial environments.

Wichtigste Unterscheidungsmerkmale
- Lowest VDD range in PIC16F18325 family (1.8 V to 3.6 V) (vs. PIC16F18325T-I/ST)
- Core Independent Peripherals (CLC, NCO, CWG, PPS) reduce CPU load (vs. PIC16F1823T-I/SL)
- 14 KB Flash with PIC16 instruction set provides largest code density (vs. ATTINY816-SNR)
Designhinweise
The PIC16LF18325T-I/ST operates from 1.8 V to 3.6 V. For designs using a 5V rail, select the PIC16F18325 (non-LF) variant instead. Place a 100 nF ceramic decoupling capacitor within 5 mm of the VDD pin and a 10 uF bulk capacitor on the power supply trace. The 'LF' variant supports sub-2V operation critical for single-cell Li-ion designs; do not substitute the standard F variant for LF applications without verifying minimum VDD requirements.
The 14-pin TSSOP package has 0.65 mm lead pitch - use 0.4 mm or finer PCB fabrication tolerance and keep traces from the TSSOP pads short to avoid signal integrity issues. Place decoupling capacitors within 5 mm of VDD pin 5 with the ground return via directly under the VSS pin 6 to minimize inductance. PPS allows digital peripherals to be remapped to most I/O pins, so leave GPIOs accessible on the PCB for routing flexibility.
Do not leave unused I/O pins floating - configure them as outputs driven low to minimize sleep current consumption. The MCLR pin (pin 1, shared with RA3) is enabled by default; if unused, configure it as a digital input with internal pull-up or as an output to avoid reset leakage. The ADC2 reference voltage must be configured (default VDD) before channel selection; otherwise readings are undefined. When migrating code between PIC16LF18325 and PIC16F18325, verify CONFIG registers for VDD-sensitive options.
PPS allows peripheral-to-pin remapping but cannot change pin drive strength. For SPI or EUSART signals running above 1 MHz, place series resistors near the MCU pin and keep traces matched in length. The 32 MHz internal oscillator accuracy is typically +/-2% across temperature, sufficient for UART at standard baud rates up to 115200 but marginal for CAN bus without external crystal. Use the PLL for the 48 MHz system clock when higher instruction throughput is needed.
