Microchip Technology ATSAMD20E14A-AU
The ATSAMD20E14A-AU is a high-performance, low-power microcontroller from Microchip Technology, designed to offer advanced features and connectivity for a variety of applications. This microcontroller is part of the SAM D20 family, which is based on the powerful ARM Cortex-M0+ processor, operating at a maximum frequency of 48MHz. With its rich set of peripherals, the ATSAMD20E14A-AU is a versatile choice for projects requiring a balance between power consumption and processing capability.
This particular model comes in a 32-pin TQFP (Thin Quad Flat Package) and offers 16KB of flash memory, allowing ample space for program storage. The device also contains 4KB of SRAM, which provides the space needed for running complex algorithms and managing data buffers. Additionally, it includes 2KB of EEPROM for non-volatile data storage, which is beneficial for storing configuration settings or small amounts of data that must be preserved during power cycles.
The ATSAMD20E14A-AU is equipped with a variety of peripherals, such as multiple serial communication modules (SERCOM) that can be configured as USART, UART, SPI, or I2C, making it highly adaptable for different communication requirements. It also features a 10-bit ADC (Analog-to-Digital Converter) with up to 12 channels, allowing for precise analog signal measurement. The device supports touch sensing with its built-in Peripheral Touch Controller, making it ideal for implementing user interfaces with capacitive buttons or sliders.
For timing and control, the microcontroller includes multiple 16-bit timers, a 32-bit Real-Time Counter (RTC), and a Watchdog Timer for system reliability. It also supports external interrupts and has a range of I/O pins for interfacing with sensors, actuators, and other electronic components.
With its low power consumption modes, including Idle and Standby, the ATSAMD20E14A-AU is particularly suited for battery-powered applications, portable devices, and energy-sensitive projects. It is fully supported by Microchip's development tools, software libraries, and the Atmel START code configuration platform, simplifying the development process and accelerating time to market.
