Microchip PIC16F1824-I/ST 8-Bit Microcontroller Overview and Application Guide
The Microchip PIC16F1824-I/ST is a versatile 8-bit microcontroller unit (MCU) from Microchip Technology’s enhanced mid-range PIC16F family. Housed in a compact TSSOP-14 package, this MCU is engineered to deliver a balanced combination of performance, power efficiency, and peripheral integration, making it an ideal solution for a wide array of embedded control applications.
At its core, the PIC16F1824 leverages an enhanced 8-bit RISC architecture with a maximum operating frequency of 32 MHz, offering a substantial performance boost over its baseline predecessors. This is complemented by its nanowatt XLP technology, which is critical for battery-powered and energy-sensitive applications, enabling extremely low current consumption in various sleep modes.
A key strength of this MCU lies in its rich set of integrated peripherals. It features:
- Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART): Facilitates robust serial communication (UART, LIN).
- Master Synchronous Serial Port (MSSP): Supports both I²C and SPI communication protocols.
- Complementary Waveform Generator (CWG): Useful for motor control and power conversion applications.
- 5-channel 10-bit Analog-to-Digital Converter (ADC): Allows for precise analog signal measurement.
- Two configurable logic cells (CLC) and a numerically controlled oscillator (NCO): These advanced peripherals allow for on-the-fly logic customization and highly precise frequency generation, respectively, reducing the need for external components.
The device also includes mTouch capacitive sensing hardware, enabling the straightforward implementation of touch interfaces without complex external circuitry.
Application Guide
The integration of these features opens the door to numerous applications. Its small form factor and communication capabilities make it perfect for smart sensors and IoT nodes that require data logging and transmission. The combination of the CWG, ADC, and robust timing peripherals positions it as an excellent choice for motor control in small appliances, such as fans and pumps. Furthermore, its low power consumption and touch sensing support are ideal for consumer electronics like remote controls, touch-activated switches, and portable devices.
Development is streamlined by Microchip’s comprehensive ecosystem, including the MPLAB X IDE and the PICkit™ 4 programmer. Engineers can quickly prototype and deploy designs using this powerful hardware and software support.
The PIC16F1824-I/ST stands out as a highly integrated and power-efficient 8-bit microcontroller. Its blend of core performance, advanced peripherals like CLC and NCO, and ultra-low-power operation makes it a superior choice for designers tackling complex control tasks in space-constrained and battery-dependent products.
