Microchip Technology's PIC16F628-20I/P Microcontroller

The PIC16F628-20I/P is a powerful 8-bit microcontroller from Microchip Technology that combines performance with versatility to meet the demands of a wide array of applications. This microcontroller operates at a maximum frequency of 20MHz and is housed in a 18-pin PDIP (Plastic Dual In-line Package), making it suitable for through-hole PCB assembly methods.

One of the key features of the PIC16F628-20I/P is its Flash-based program memory, which has a size of 3.5KB. This non-volatile memory allows for easy reprogramming and updating of the firmware, which is essential for iterative development processes and long-term product support. Additionally, the device boasts 128 bytes of EEPROM data memory, which can be used to store configuration settings or small amounts of data that must be preserved during power cycles.

The microcontroller includes 224 bytes of RAM, which is used for temporary data storage and operation during execution of the program. The PIC16F628-20I/P also supports an array of peripherals and interfaces that can be crucial for embedded systems. These include two timers, a synchronous serial port that can be configured as either 3-wire SPI or 2-wire I2C™, and an asynchronous (E)USART module, which supports RS-232 and RS-485 communication.

Another significant feature of the PIC16F628-20I/P is its 16 I/O pins, which provide the flexibility to connect with various external devices. The microcontroller also includes an 8-channel 10-bit Analog-to-Digital converter, allowing it to interface with analog sensors and transducers directly. Furthermore, the device features a programmable code protection system to prevent unauthorized reading or copying of the firmware, which is essential for protecting intellectual property.

Microchip's PIC16F628-20I/P operates within the industrial temperature range of -40°C to +85°C, ensuring reliability across diverse environmental conditions. It is ideal for applications in the fields of automation, consumer electronics, automotive systems, and more. With its rich set of features, this microcontroller is designed to provide a cost-effective solution for both complex and simple embedded tasks.

Whether you are developing a new project or upgrading an existing one, the PIC16F628-20I/P offers a perfect blend of power, flexibility, and ease of use, making it an excellent choice for your microcontroller needs.
