NRND13,202 in stock
Overview
The ATMEGA88-20AUR is a high-performance, low-power 8-bit microcontroller based on the AVR enhanced RISC architecture. It operates at up to 20MHz and features 8KB of self-programmable Flash memory, 1KB of RAM, and 512 bytes of EEPROM in a compact 32-pin TQFP package.
Why Choose This Part
The device features a hardware 2-cycle multiplier and 131 powerful instructions, most of which execute in a single clock cycle for efficient processing. Its low power consumption of 0.3mA at 1MHz and multiple sleep modes make it suitable for energy-sensitive applications.
Applications
Industrial Control Systems
Utilizing the on-chip PWM and 23 I/O lines for basic motor control and relay switching.
Handheld Battery-Powered Devices
Leveraging power-save and power-down modes to extend battery life in portable instrumentation.
Sensor Interface Nodes
Processing analog signals via the ADC and communicating results over I2C or SPI to a master controller.
User Interface Modules
Managing small keypads and character LCDs using dedicated GPIO and timer interrupts.
