Microchip ATMEGA168V-10AUR: An 8-Bit AVR Microcontroller Datasheet and Application Overview
The Microchip ATMEGA168V-10AUR stands as a testament to the enduring power and versatility of high-performance 8-bit AVR RISC architecture. This microcontroller, housed in a compact 32-pin TQFP package, is engineered for a wide array of embedded control applications, balancing processing capability with exceptional power efficiency.
Core Architectural Features
At its heart, the device features a powerful AVR 8-bit RISC CPU core capable of executing most instructions in a single clock cycle. This allows it to achieve a throughput approaching 1 MIPS per MHz, optimizing its performance for speed-critical tasks even when operating at its maximum clock frequency of 10MHz. The core is supported by 16KB of in-system self-programmable Flash memory for code storage, 1KB of SRAM for data handling, and 512Bytes of EEPROM for non-volatile data storage, providing ample resources for complex programs.
Advanced Peripherals and Integration
A key strength of the ATMEGA168V-10AUR is its rich set of integrated peripherals, which minimizes external component count and simplifies design. It includes two 8-bit and one 16-bit Timer/Counters with dedicated compare modes, a versatile 10-bit ADC with up to 8 channels, and a programmable Serial USART for robust serial communication. Furthermore, it supports Serial Peripheral Interface (SPI) and Two-wire Serial Interface (I²C), enabling easy connection to a vast ecosystem of sensors, memories, and other ICs. The inclusion of a programmable Watchdog Timer with an internal oscillator enhances system reliability.
Power Efficiency and Management
Designed for low-power applications, the microcontroller excels in power-sensitive scenarios. It features multiple sleep modes, including Idle, ADC Noise Reduction, Power-save, Power-down, and Standby. These modes allow the system to dramatically reduce power consumption during periods of inactivity, making it ideal for battery-operated devices. The ability to operate down to 1.8V further extends its usability in portable electronics.
Application Overview
The combination of its processing power, integrated features, and low-energy operation makes the ATMEGA168V-10AUR suitable for a diverse range of applications. It is perfectly suited for:
Automotive Control Systems: Sensor interfacing and body control modules.
