ATMEGA3290PA-AU Description

Short technical summary and product information.

The ATMEGA3290PA-AU is an 8-bit AVR microcontroller from Microchip Technology based on the high-performance, low-power AVR RISC architecture. It features 32KB of in-system self-programmable flash memory, 2KB internal SRAM, and 1KB EEPROM, providing ample storage for code and data. The device operates at a maximum frequency of 20MHz, delivering up to 20 MIPS throughput. It includes 69 general-purpose I/O lines and a rich set of peripherals: two 8-bit timers, one 16-bit timer, 4 PWM channels, an 8-channel 10-bit ADC, and a 4x40 segment LCD driver. Connectivity options include SPI, UART/USART, and USI interfaces. The MCU supports JTAG for boundary-scan and on-chip debug, and offers five sleep modes for power-sensitive applications. Housed in a 100-TQFP (14x14mm) surface-mount package, it operates over an industrial temperature range of -40°C to 85°C and requires a supply voltage of 2.7V to 5.5V.
