Microchip Technology PIC18LF47K40-I/MV Microcontroller

The PIC18LF47K40-I/MV is a high-performance microcontroller unit (MCU) from Microchip Technology, designed to cater to a wide range of applications requiring efficient power management and sophisticated functionality. This MCU is part of the PIC18 family, known for its robust architecture and enhanced features that make it ideal for embedded systems in industrial, automotive, and consumer electronics.

At the core of the PIC18LF47K40-I/MV is an 8-bit processor with an extended operating voltage range of 1.8V to 3.6V, which allows for low-power operation and helps in extending battery life in portable applications. This microcontroller comes with 128 KB of flash memory and 8 KB of SRAM, providing ample space for application code and data storage. Additionally, it boasts 1024 bytes of EEPROM, which is useful for non-volatile storage of configuration parameters or small amounts of data that must be retained during power cycles.

The microcontroller features a rich set of peripherals, including:

• Up to 35 I/O pins with interrupt-on-change capability
• Five 16-bit timers and one 8-bit timer to manage timing tasks
• Three Enhanced Capture/Compare/PWM (ECCP) modules for advanced pulse-width modulation
• Two Comparators and a Complementary Waveform Generator (CWG) for complex waveform generation
• Two serial communication modules supporting SPI, I2C, and UART protocols for versatile connectivity options
• 12-bit Analog-to-Digital Converter (ADC) with Computation (ADCC) for precise analog signal measurement and processing
• 25 mA source/sink current I/O for driving LEDs or other loads directly

Furthermore, the PIC18LF47K40-I/MV supports advanced features like Direct Memory Access (DMA), which enables faster data transfers without CPU intervention, and Peripheral Pin Select (PPS), which provides flexibility in pin mapping for various peripherals. The device also incorporates various safety features, including a Brown-Out Reset (BOR), a Watchdog Timer (WDT), and a Configurable Voltage Reference (CVR) to ensure reliable operation under varying conditions.

This MCU is available in a 40-pin UQFN package, which is suitable for space-constrained applications. Its extended temperature range and robust design make the PIC18LF47K40-I/MV a versatile choice for developers looking to create sophisticated and power-efficient applications.
