ATMEGA6490V-8AU Description

Short technical summary and product information.

The ATMEGA6490V-8AU is a low-power 8-bit AVR microcontroller from Microchip Technology, based on the advanced RISC architecture. It offers 64KB of in-system self-programmable Flash memory, 4KB SRAM, and 2KB EEPROM with high endurance (10,000 write/erase cycles for Flash, 100,000 for EEPROM) and data retention of 100 years at 25°C or 20 years at 85°C.

 

The microcontroller operates over a supply voltage range of 1.8V to 5.5V, with a maximum clock speed of 8MHz at 2.7V-5.5V and 4MHz at 1.8V-5.5V. It integrates a rich set of peripherals including a 4x40 segment LCD driver, 8-channel 10-bit ADC, USART, SPI, and Universal Serial Interface (USI). Additional features include brown-out detection, power-on reset, programmable watchdog timer, and five sleep modes for power saving.

 

Packaged in a 100-TQFP (14x14mm) surface mount package with 68 I/O lines, the ATMEGA6490V-8AU is suitable for applications requiring display control, low-power operation, and moderate processing. The device is designed for industrial temperature ranges (-40°C to 85°C) and is ideal for embedded systems in instrumentation, automation, and consumer electronics.
