PIC16F1825T-I/JQ 개요
An 8-bit microcontroller (MCU) is a self-contained computing device that integrates a CPU, program memory (Flash), data memory (RAM), and peripherals on a single silicon die. PIC microcontrollers use a RISC architecture with a fixed-width instruction set optimized for deterministic embedded control. The PIC16F1825 belongs to the enhanced mid-range PIC16F family, positioned between baseline PIC10/12 and 16-bit PIC24/dsPIC families.
Key features include nanoWatt XLP extreme-low-power technology for battery-friendly designs, an integrated temperature indicator, two 10-bit ADC modules, up to 12 I/O pins, and support for In-Circuit Serial Programming (ICSP) without requiring an external programmer header. The automotive-grade variant is AEC-Q100 qualified, and the device supports a wide 1.8V to 5.5V operating voltage range.
The PIC16F1825 architecture is built around a 14-bit instruction word, 8-bit data path, and hardware multiplier, providing efficient code density for embedded applications. The device supports Core Independent Peripherals (CIPs) such as Configurable Logic Cells (CLC), Complementary Waveform Generator (CWG), and Numerically Controlled Oscillator (NCO) that execute complex timing tasks without CPU intervention.
Typical applications include consumer electronics, IoT sensor nodes, automotive body electronics, LED lighting control, capacitive touch interfaces, and small motor control. The combination of low power consumption, ample Flash for application code, and rich analog peripherals makes it a versatile general-purpose MCU.
Designers should note that the UQFN-16 EP package has an exposed thermal pad that must be soldered to the PCB ground pour for mechanical reliability and optimal thermal dissipation. The ICSP pins (ICSPCLK and ICSDAT) must be accessible for programming and debugging, even in production layouts.

IoT Wireless Sensor Node
The PIC16F1825T-I/JQ fits IoT wireless sensor nodes through its nanoWatt XLP extreme-low-power technology that delivers sleep currents below 1 microampere, preserving coin-cell battery life over multi-year deployments. Its 14 KB Flash accommodates typical LoRaWAN or BLE protocol stacks with margin for OTA update images, while the 10-bit ADC and comparators directly interface with analog sensor front-ends. Operating from 1.8 V to 5.5 V allows direct connection to single-cell lithium or two-cell alkaline sources.

Capacitive Touch User Interface
The PIC16F1825T-I/JQ suits capacitive touch keypads and slider interfaces through its integrated mTouch capacitive-sensing module supported by the Core Independent Peripherals (CIPs) architecture, which executes touch scanning without CPU intervention to minimize current draw. The Configurable Logic Cells (CLC) and Complementary Waveform Generator (CWG) deliver flexible hardware-only timing for advanced UI features. The 16-pin UQFN-EP package is small enough for handheld remote-control form factors.

LED Lighting Control
The PIC16F1825T-I/JQ drives LED lighting systems through its four 10-bit PWM channels, two comparators, and 32 MHz CPU clock that together provide smooth dimming curves and high-frequency PWM to avoid visible flicker. Operating across 1.8 V to 5.5 V enables direct drive from rectified mains-derived rails. The 14 KB Flash supports DMX512, DALI, or proprietary lighting protocols while the EUSART and I2C peripherals interface with LED driver ICs.

설계 노트
The UQFN-16 EP package has an exposed thermal pad on the underside that MUST be soldered to a PCB ground pour for both mechanical reliability and optimal thermal dissipation. Provide at least 4 thermal vias connecting the central pad to inner ground planes. Without the exposed-pad solder connection, the package is prone to cracking under thermal stress and the IC's electrical ground reference becomes unreliable.
Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 15) and a 10 uF bulk capacitor nearby on the power trace. According to Microchip PIC16F/LF182X datasheet guidance, decoupling capacitors should be placed within 1-2 mm of the supply pins to suppress high-frequency switching noise from internal core logic and to stabilize ADC reference readings.
The ICSP programming pins (RA4/ICSDAT and RA5/ICSPCLK) must remain accessible in the production PCB layout to enable in-circuit programming and debugging. Pull-up resistors on these lines are NOT required because Microchip programmers provide them internally, but series resistors around 100 ohms are recommended to isolate the ICSP signals from application circuitry during programming sessions.
The MCLR reset pin (RA3) requires a 10 kohm pull-up to VDD for reliable operation. An optional 100 nF capacitor from MCLR to ground provides noise filtering for harsh environments. Never drive MCLR low during normal operation except for true reset events, since spurious resets can corrupt Flash program memory and trigger unexpected peripheral re-initialization.
규정 준수 정보
