Microchip ATMEGA88V-10AUR: A Comprehensive Technical Overview of the 8-Bit AVR Microcontroller
The Microchip ATMEGA88V-10AUR stands as a quintessential representative of the highly successful and versatile 8-bit AVR microcontroller family. Engineered for a wide array of embedded control applications, this MCU combines a powerful RISC architecture with a rich peripheral set, all within a low-power envelope, making it a preferred choice for designers from hobbyists to industrial engineers.
Architectural Core and Performance
At the heart of the ATMEGA88V-10AUR lies a high-performance, low-power Atmel AVR 8-bit RISC core. It can execute most instructions in a single clock cycle, achieving a throughput approaching 1 MIPS per MHz, enabling efficient and speedy processing for complex tasks. The "-10" in its part number denotes its capability to run at clock speeds up to 10 MHz with a supply voltage (VCC) as low as 1.8V, a feature highlighted by the "V" for its wide voltage range operation from 1.8V to 5.5V. This makes it exceptionally suited for battery-powered and low-power applications.
Memory Configuration
The device is equipped with three core memory spaces:
8 KB of In-System Self-Programmable Flash memory for program storage. This non-volatile memory allows for thousands of write/erase cycles, facilitating easy firmware updates in the field.
1 KB of SRAM provides essential volatile data storage for efficient program execution and variable manipulation.
512 Bytes of EEPROM offers a separate non-volatile memory space for critical data that must be retained even after power loss, such as calibration constants or device settings.
Integrated Peripherals and Features
The ATMEGA88V-10AUR is renowned for its extensive suite of integrated peripherals, which reduces system component count and overall cost. Key features include:
Two 8-bit Timer/Counters and One 16-bit Timer/Counter with separate prescalers and compare modes.
Real Counter with Separate Oscillator allows timekeeping even in low-power modes.
6-channel 10-bit ADC (Analog-to-Digital Converter) for precision analog sensor data acquisition.
Programmable Serial USART, Master/Slave SPI Serial Interface, and Byte-oriented 2-wire Serial Interface (I2C) for comprehensive communication capabilities.
Programmable Watchdog Timer with separate on-chip oscillator for enhanced system reliability.
On-chip Analog Comparator for monitoring analog signals without using the ADC.
Packaging and Applications
The "AUR" suffix indicates the device is in a 32-pin TQFP (Thin Quad Flat Pack) package. This surface-mount package offers a compact footprint while providing access to a full set of I/O pins, making it ideal for space-constrained PCB designs. Its combination of performance, low power, and rich integration makes it perfect for a myriad of applications, including industrial control systems, sensor nodes, consumer electronics, automotive peripherals, and countless DIY projects.
ICGOOODFIND: The Microchip ATMEGA88V-10AUR is a highly integrated and power-efficient 8-bit microcontroller. Its robust RISC architecture, substantial memory for its class, wide operating voltage, and extensive peripheral set make it an exceptionally versatile and reliable solution for a vast range of embedded control and sensing applications, balancing performance with low power consumption effectively.
