PIC16LF1825-I/ST - 14KB Flash 8-bit MCU 32MHz | Microchip
The Microchip Technology PIC16LF1825-I/ST is an 8-bit PIC microcontroller based on the enhanced mid-range PIC16 core, delivering 32 MHz CPU performance with 14 KB Flash program memory, 1 KB RAM, and 256 bytes of EEPROM in a 14-pin TSSOP package. It features nanoWatt XLP extreme-low-power technology, an integrated mTouch capacitive sensing peripheral, and 12 I/O pins.
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash/ROM), data memory (RAM), and peripherals onto one die. Within the broader taxonomy, an MCU belongs to the family of microcontrollers, then to embedded controllers, then to integrated circuits. The PIC16 family is Microchip's mid-range 8-bit architecture, sitting between the baseline PIC10/12/16 and the high-performance PIC18 families, and is widely used in cost-sensitive, low-power embedded designs.
Key features of the PIC16LF1825 include: 32 MHz internal oscillator with PLL (8 MIPS), 1.8-3.6 V wide operating voltage range, 12-channel 10-bit ADC with hardware Capacitive Voltage Divider (CVD), two analog comparators, four 8-bit timers plus one 16-bit timer, an Enhanced Universal Synchronous/Asynchronous Receiver/Transmitter (EUSART), and two SPI/I2C peripherals. The device also supports mTouch capacitive touch sensing, peripheral pin select (PPS), and on-board CTMU charge-time measurement hardware.
Architecturally, the PIC16LF1825 uses a 14-bit instruction word with a single-cycle ALU, dual-bank Flash memory, an instruction cache, and a flexible oscillator block supporting internal 32 kHz-32 MHz operation without external components. The mTouch and CVD blocks enable robust proximity and touch buttons with no external passive components, making the part well suited for sealed-user-interface products.
Typical applications include consumer touch-interface products (small kitchen appliances, white goods control panels), battery-powered IoT sensor nodes, low-cost remote controls, LED lighting controllers, and home-automation switch modules. The wide 1.8-3.6 V supply range also makes it suitable for direct 3.3 V or 2xAA battery systems.
When designing with the PIC16LF1825, place the decoupling capacitor (100 nF plus 1-10 µF bulk) within 5 mm of the VDD pin and use the on-chip PLL only when VDD ≥ 2.5 V to maintain full 32 MHz operation. The peripheral pin select (PPS) feature lets remap digital peripherals to any I/O, simplifying PCB layout when routing multiple UART, SPI, or PWM signals.
