series introduction

# Introduction to the PIC16LF628T - 04I/SO Product Series

## 1. Overview
The PIC16LF628T - 04I/SO is a member of Microchip Technology's PIC16F family of 8 - bit microcontrollers. These microcontrollers are known for their high - performance, low - power consumption, and versatility, making them suitable for a wide range of applications. The "LF" in the part number indicates that it is a low - power device, which is ideal for battery - powered or energy - sensitive applications. The "04" represents the clock speed and other performance - related parameters, and "I/SO" refers to the package type, which is a Small Outline (SO) package.

## 2. Key Features

### 2.1 Low - Power Operation
One of the most significant features of the PIC16LF628T - 04I/SO is its low - power consumption. It operates on a wide range of supply voltages, typically from 2.0V to 5.5V. This wide voltage range allows it to be used in various power - supply scenarios, from small coin - cell batteries to standard 5V power sources. The device has different power - saving modes, such as Sleep mode, where the microcontroller can consume as little as a few microamperes of current. This makes it an excellent choice for applications that require long battery life, such as wireless sensors, remote controls, and wearable devices.

### 2.2 High - Performance CPU
The PIC16LF628T - 04I/SO is equipped with a high - performance RISC (Reduced Instruction Set Computing) CPU. It has a Harvard architecture, which separates the program memory and data memory buses. This architecture allows for simultaneous access to program and data memory, resulting in faster execution of instructions. The microcontroller can execute instructions in a single cycle, providing a high level of processing power for its class. It has a maximum operating frequency of 4 MHz, which is sufficient for many real - time control and monitoring applications.

### 2.3 Memory Configuration
- **Program Memory**: It has 1024 words of Flash program memory. Flash memory is non - volatile, which means that the program code stored in it is retained even when the power is turned off. This allows for easy reprogramming of the microcontroller during development and in - field updates if required.
- **Data Memory**: The device has 68 bytes of RAM (Random Access Memory) for storing variables and intermediate results during program execution. This amount of RAM is adequate for most small - to - medium - sized applications.

### 2.4 Peripherals
- **I/O Ports**: The PIC16LF628T - 04I/SO has multiple general - purpose I/O (GPIO) pins. These pins can be configured as either input or output ports, allowing the microcontroller to interface with external devices such as sensors, actuators, and displays. The I/O pins are also programmable for weak - pull - up resistors, which can simplify the design of input circuits.
- **Timers/Counters**: It includes several timers and counters, such as the 8 - bit Timer0 and the 16 - bit Timer1. These timers can be used for a variety of purposes, including generating time delays, measuring time intervals, and generating PWM (Pulse Width Modulation) signals. PWM signals are commonly used for controlling the speed of motors, the brightness of LEDs, and other applications that require variable power control.
- **Comparator Module**: The microcontroller features a comparator module that can compare two analog input voltages. This can be used for applications such as voltage monitoring, level detection, and analog -
