Atmel has released five new high performance, low power AVR Flash microcontrollers. These devices target applications requiring a large code space and extensive interfacing capability, such as single-board computers.
The ATmega640, ATmega1280 and ATmega2560 come in a 100-pin housing, while the ATmega1281 and ATmega2561 has 64 pins. The devices feature 64 to 256 Kbytes of Flash program memory, and 8 Kbytes of on-chip RAM. With linear address range up to 8 MB, the AVR devices can handle this amount of memory with no paging.
The new device family significantly reduces complete system chip count requirements. An integrated 8 MHz RC oscillator can be calibrated to an accuracy of ±2%, avoiding the need for an external crystal in many applications. A watchdog timer running from an independent RC oscillator, and a brown-out detector is also included, ensuring safe operation at minimum cost.
