The mega329/649/3290/6490 flash memory microcontrollers are designed to address the requirements of portable and battery-operated applications that need to interface with an LCD. These devices combine a code-efficient and powerful microcontroller with a low-power flash memory technology. The mega329 and mega649 have an integrated 100-segment LCD controller. They are housed in a 64-pin package. The mega3290 and mega6490 have a 160-segment LCD controller. They are available in a 100-pin package.

Members of this family of microcontrollers consume only 300 µA at an operating frequency of 1 MHz. They have a throughput of 2 MIPS per milliwatt. In Power-Down mode, all peripherals, with the exception of external interrupts, are turned off and power consumption drops to 100 nA. These parts are extremely responsive to external events in both Active and Power-Down modes. Interrupts on up to 18 inputs can wake the MCUs from Power-Down mode in less than 1 µs.

The mega329 and 3290 cost $4.50 and $4.95, respectively, in 10,000-piece quantities. The mega649 and mega6490 will be available in early 2005 and cost $5.25 and $5.75, respectively. Evaluation and debug tools are available.
