ATTINY461-15MAZ Series

series introduction

# Introduction to the ATTINY461 - 15MAZ Product Series

## 1. Overview
The ATTINY461 - 15MAZ is a member of the ATTINY microcontroller product family developed by Microchip Technology. This series of microcontrollers is designed to offer a high - performance, cost - effective solution for a wide range of embedded applications. With its compact size, low power consumption, and rich set of features, the ATTINY461 - 15MAZ is well - suited for projects where space and energy efficiency are crucial.

## 2. Key Features

### 2.1 Processing Power
- **Microcontroller Core**: It is based on the AVR enhanced RISC architecture. This architecture provides a high - speed instruction execution rate, allowing the microcontroller to handle complex tasks efficiently. The core can execute most instructions in a single clock cycle, which significantly improves the overall performance of the device.
- **Clock Speed**: The "15" in the part number indicates that the ATTINY461 - 15MAZ has a maximum clock speed of 15 MHz. This relatively high clock speed enables fast data processing and real - time response in applications.

### 2.2 Memory
- **Flash Memory**: The microcontroller is equipped with 4 KB of in - system self - programmable flash memory. This non - volatile memory is used to store the program code, allowing developers to easily update and modify the application software.
- **SRAM**: It has 256 bytes of static random - access memory (SRAM). SRAM is used for storing temporary data during program execution, such as variables and buffers. The sufficient SRAM capacity ensures smooth operation of the application.
- **EEPROM**: There is also 128 bytes of electrically erasable programmable read - only memory (EEPROM). EEPROM is useful for storing critical data that needs to be retained even when the power is turned off, such as calibration values or user settings.

### 2.3 I/O Capabilities
- **General - Purpose I/O Pins**: The ATTINY461 - 15MAZ has a total of 20 general - purpose input/output (GPIO) pins. These pins can be configured as either inputs or outputs, allowing the microcontroller to interface with a variety of external devices, such as sensors, actuators, and displays.
- **Peripheral Interfaces**: It supports multiple communication interfaces, including SPI (Serial Peripheral Interface) and USART (Universal Synchronous/Asynchronous Receiver/Transmitter). The SPI interface enables high - speed data transfer between the microcontroller and other SPI - compatible devices, while the USART interface can be used for serial communication with other microcontrollers or external modules.

### 2.4 Analog Features
- **Analog - to - Digital Converter (ADC)**: The microcontroller is integrated with a 10 - bit ADC. This ADC can convert analog input signals from external sensors into digital values, which can then be processed by the microcontroller. The 10 - bit resolution provides a relatively high level of accuracy for measuring analog signals.
- **Comparator**: It also includes an analog comparator. The comparator can be used to compare two analog voltages and generate a digital output based on the comparison result. This feature is useful in applications such as voltage monitoring and signal conditioning.

### 2.5 Power Management
- **Low - Power Modes**: The ATTINY461 - 15MAZ offers several low - power modes, including idle mode, power - down mode, and power - save mode. In these modes, the microcontroller can reduce its power consumption significantly by shutting down non - essential circuits. This makes it ideal for battery - powered applications where energy efficiency is a
