Flash facilitates MCU self-programming
Atmel's new family of AVR microcontrollers features a revolutionary self-programming Flash memory
Now available from design-in distributor GD Technik, the new micros are designed to support applications requiring remote programming or field-upgrade capability such as vending machines, telephone routers and mobile communicators. With the megaAVR the service costs for these applications will be significantly reduced because the Flash memory can be changed remotely.

Ethernet reference design uses Atmel ARM7
The AT91-NET Ethernet card for Atmel EB40A and EB55 ARM development boards has been developed in response to customer demand for an Ethernet port on the ARM development environment
This new capability can be implemented with a single device, without the need of additional devices, which reduces both board space and cost.
The first available members of the megaAVR family are highly integrated devices and have: from 8 to 128Kbyte of Flash program memory, EEPROM, a programmable UART, hardware multiplier, programmable brownout detector and 10bit A/D convertor.
They are housed in the industry standard 32-, 44- or 64-pin TQFPs or 28- and 40-pin PDIPs.
The megaAVR microcontroller's CPU has read-while-write capability and is able to program or reprogram the Flash memory block via the SPI, UART or two wire interface, while application code is executing in the boot block sector.
The self-programming feature can be implemented over the full temperature and voltage range.
The Flash memory of the megaAVR is divided into a boot block and application code section, which is made up of sectors containing 128byte.
The small sector size significantly reduces the programming time needed for code patches, updates and changes that do not require a complete memory update.
Lock bits can be set to protect code in the boot block or application section from unauthorised read or accidental reprogramming.
Development tools and in-circuit emulation support for the megaAVR family are also available from GD Technik.
