Product Overview: PIC16F628-04/P Microcontroller

The PIC16F628-04/P is a versatile 8-bit microcontroller from the renowned manufacturer, Microchip Technology. Designed to deliver performance with economy, this microcontroller finds its place in a variety of embedded applications. The PIC16F628-04/P is housed in a PDIP (Plastic Dual In-line Package) and is characterized by its ease of use and powerful features.

At the heart of the PIC16F628-04/P is a RISC architecture that allows for fast execution of instructions, typically within a single clock cycle. The device operates at a frequency of 4MHz, providing a balanced trade-off between speed and power consumption. It is equipped with 3.5KB of flash memory which provides ample space for application code and is reprogrammable, allowing for iterative development and firmware updates.

The microcontroller comes with 224 bytes of EEPROM data memory, which is useful for storing non-volatile data that must be preserved between resets or power cycles. Additionally, it has 128 bytes of RAM, ensuring smooth operation and data handling in complex tasks.

An array of built-in peripherals makes the PIC16F628-04/P a highly integrated solution. This includes two timers, a watchdog timer, an 8-channel 10-bit Analog-to-Digital Converter (ADC), and two Capture/Compare/PWM (CCP) modules. These features enable the microcontroller to handle a wide range of functions such as sensor interfacing, motor control, and other timing-critical tasks without the need for additional components.

For communication, the device supports USART (Universal Synchronous Asynchronous Receiver Transmitter) for serial communication, which can be configured for various serial protocols like RS-232, RS-485, and more. The in-circuit serial programming (ICSP) capability simplifies programming and debugging, as it allows the microcontroller to be programmed after being placed in a circuit board.

To ensure reliability, the PIC16F628-04/P features Power-on Reset (POR), Device Reset Timer (DRT), and Brown-out Reset (BOR). These protective mechanisms safeguard the microcontroller from unexpected power fluctuations and ensure stable operation in unpredictable environments.

Whether you're designing a simple DIY project or a sophisticated industrial control system, the PIC16F628-04/P offers a compact, cost-effective solution with its rich set of features and Microchip's reputation for quality.
