# PIC32MX120F032B - I/ML Product Series Introduction

## 1. Overview
The PIC32MX120F032B - I/ML is a member of Microchip Technology's PIC32MX family of 32 - bit microcontrollers. This product series is designed to offer a cost - effective and high - performance solution for a wide range of embedded applications. With its rich set of features, it bridges the gap between the simplicity of 8 - bit microcontrollers and the advanced capabilities of 32 - bit processors, making it an ideal choice for developers looking to upgrade their designs without a significant increase in complexity or cost.

## 2. Key Features

### 2.1 Processor Core
- **MIPS32® M4K® Core**: The PIC32MX120F032B - I/ML is powered by the MIPS32® M4K® core, which operates at up to 80 MHz. This core provides a high - performance processing engine with a 32 - bit instruction set and a Harvard architecture, allowing for simultaneous access to program and data memory. It offers a high level of code density and efficient execution, enabling developers to write compact and fast - running applications.
- **Hardware Multiplier and Divider**: The inclusion of a hardware multiplier and divider in the core significantly speeds up mathematical operations such as multiplication, division, and modulo. This is particularly useful in applications that require real - time signal processing, control algorithms, and complex calculations.

### 2.2 Memory
- **Flash Memory**: It comes with 32 KB of in - system programmable flash memory. This non - volatile memory is used to store the application code, allowing for easy updates and reprogramming. The flash memory has a high endurance, ensuring reliable operation over a long period.
- **SRAM**: The microcontroller features 8 KB of static random - access memory (SRAM). SRAM is used for storing variables, data buffers, and the stack during program execution. The sufficient amount of SRAM enables the implementation of complex algorithms and data - intensive applications.

### 2.3 Peripherals

#### 2.3.1 Communication Peripherals
- **Universal Synchronous/Asynchronous Receiver/Transmitter (USART)**: The PIC32MX120F032B - I/ML is equipped with one USART module, which supports both synchronous and asynchronous serial communication. It can be used for communication with other microcontrollers, sensors, or external devices using protocols such as RS - 232, RS - 485, or SPI.
- **Inter - Integrated Circuit (I²C)**: An I²C module is available, allowing for easy connection to a wide range of I²C - compatible devices such as sensors, EEPROMs, and displays. The I²C interface supports both master and slave modes, providing flexibility in system design.
- **Serial Peripheral Interface (SPI)**: The SPI module enables high - speed serial communication with external devices. It supports multiple slave devices and can operate at high clock frequencies, making it suitable for applications that require fast data transfer, such as communication with external memory chips or display controllers.

#### 2.3.2 Timers and Counters
- **Multiple Timers**: The microcontroller includes several timers, including general - purpose timers and capture/compare/PWM (CCP) modules. These timers can be used for a variety of applications, such as generating accurate time delays, measuring input signal frequencies, and generating pulse - width modulated (PWM) signals for motor control or LED dimming.

#### 2.3.3 Analog - to - Digital Converter (ADC)
- **10 - bit ADC**: The PIC
