Microcontrollers datasheet and documents for ATMEGA6450A-AUR

ATMEGA6450A-AUR

Microcontrollers Overview

The ATMEGA6450A-AUR is an 8-bit AVR microcontroller featuring a 20MHz operating speed and 100-pin TQFP package. It includes 64KB of in-system programmable Flash, 2KB EEPROM, and 4KB internal SRAM. The device supports a supply voltage range of 1.8V to 5.5V and operates within an industrial temperature range of -40°C to +85°C.

Microcontrollers Feature Summary

Advanced RISC architecture with up to 20 MIPS throughput at 20MHz
In-system self-programmable Flash with true read-while-write capability
JTAG interface for boundary-scan and on-chip debugging support
Integrated capacitive touch sensing via QTouch library support

Microcontrollers Applications

Industrial control systems
Computer peripheral devices
Smart alarm applications

Microcontrollers Procurement Notes

Verify the 'R' suffix indicates tape-and-reel packaging rather than tray distribution. Confirm the specific speed grade matches project requirements, as variants exist with different maximum frequencies. Ensure the manufacturer designation aligns with current Microchip Technology standards following the Atmel acquisition.

Microcontrollers Selection Notes

Select this component when high memory capacity and extensive I/O lines are required. The 100-pin TQFP package provides access to additional ports compared to smaller footprints. Verify that the 20MHz speed grade meets processing demands and that the 1.8V minimum supply voltage suits low-power design constraints.

Microcontrollers Part Context

This part belongs to the ATmega6450 family, which shares core architecture with the ATmega6450P variant. The primary distinction lies in the package type; the 'AU' suffix denotes the TQFP form factor suitable for surface-mount assembly. It represents a high-density solution within the enhanced RISC AVR line.
