PIC16F690-I/ML Typical application Circuitry

PIC16F690-I ML

The PIC16F690-I/ML is a versatile microcontroller (MCU) designed by Microchip Technology, which is part of their PIC16F family. This MCU is well-suited for a broad range of applications, thanks to its compact size, efficiency, and rich set of features.

Key Features:

- 8-bit Processor: Efficient for controlling a wide array of applications with sufficient computational power for a multitude of tasks.

- Flash Memory: Comes with 7 KB of flash memory, providing ample space for application code.

- RAM and EEPROM: Features 256 bytes of RAM and 256 bytes of EEPROM, useful for temporary data storage and non-volatile storage needs.

- I/O Pins: Offers up to 20 I/O pins, allowing for robust peripheral device control.

- ADCs and Communication Interfaces: Equipped with a 10-bit Analog-to-Digital Converter (ADC) with up to 12 channels and communication interfaces such as SPI, I2C, and USART for versatile peripheral and sensor integration.

Application Scenario - Simple Weather Station:

A simple weather station represents an ideal application for the PIC16F690-I/ML, capable of monitoring temperature, humidity, and atmospheric pressure.

Circuit Connection Details:

- Power Supply Connection: The VDD and VSS pins should be connected to a +5V power source and ground, respectively, ensuring the PIC16F690-I/ML receives the necessary power for operation.

- Temperature Sensor Interface: Connect a temperature sensor, like the LM35, to an ADC input pin (e.g., AN0). This setup enables the MCU to measure ambient temperature.

- Humidity Sensor: A humidity sensor, such as the HIH-4000, can be interfaced with another ADC input pin (e.g., AN1) to monitor the humidity level.

- Barometric Pressure Sensor: An I2C barometric pressure sensor, like the BMP280, can be connected to the SDA and SCL pins, allowing the MCU to track atmospheric pressure.

- Programming Pins: For uploading firmware to the PIC16F690-I/ML, the PGD (Program Data) and PGC (Program Clock) pins are utilized. These should be connected to a compatible programmer, like the MPLAB ICD or PICkit. The MCLR pin is also crucial for device resetting during programming.

- LCD Display Interface: An LCD display can be connected to several I/O pins (e.g., RB0-RB7 for an 8-bit interface) for data visualization, displaying temperature, humidity, and pressure readings in real-time.

Design Considerations:

- Power Decoupling: It's crucial to include decoupling capacitors near the power pins of the PIC16F690-I/ML to minimize power supply noise and ensure stable operation.

- Sensor Calibration: Calibration routines may be necessary for the sensors to ensure accurate readings, which involves both hardware setup and software algorithms.

- LCD Contrast Adjustment: For the LCD display, a potentiometer may be required to adjust the contrast, ensuring the display is readable under various lighting conditions.

- I2C Pull-up Resistors: Remember to add pull-up resistors on the SDA and SCL lines when interfacing with I2C devices like the BMP280 to ensure proper communication.

- Programming and Debugging Access: Ensure that the programming pins are easily accessible for updates and troubleshooting, possibly including a header on the PCB for connecting the programmer/debugger.

By addressing these design elements, developers can create a functional and reliable simple weather station using the PIC16F690-I/ML, showcasing the microcontroller's capabilities in sensor interfacing, data processing, and user interaction.
