PIC18F25Q43-I/SS PIC XLP™ 18F Microcontroller 32KB Flash 12-bit ADC MCU
The PIC18F25Q43-I/SS is an 8-bit microcontroller powered by Microchip's enhanced PIC18 XLP™ core, operating at up to 64 MHz for high-speed execution in cost-sensitive applications. It integrates a 32 KB Flash memory with self-programming capability, enabling firmware updates via I2C™, SPI, or UART interfaces without external tools. The 2 KB SRAM and 1 KB EEPROM provide ample storage for dynamic data and configuration parameters, while the 8-bit ALU with hardware multiplier accelerates mathematical operations in motor control or signal processing tasks. Its 25 I/O pins support flexible peripheral mapping, and the low-power sleep mode (<1 µA @ 3V) makes it ideal for battery-powered devices like sensors and wearables.
This MCU features a rich set of integrated peripherals, including four 12-bit ADC channels (24 total multiplexed inputs) for precise analog sensing, two 8-bit DACs for waveform generation, and two comparators with hysteresis for voltage monitoring. For communication, it offers UART (RS-232/RS-485 compatible), SPI, and I2C™ (SMBus 2.0/3.0) interfaces, enabling seamless connectivity to sensors, displays, and wireless modules. The MCU also includes three 16-bit PWMs with independent duty cycles, a watchdog timer (WDT) for system reliability, and a configurable brown-out reset (BOR) to protect against voltage fluctuations. Its 28-SSOP package supports surface-mount assembly, balancing compactness and ease of prototyping.
