AVR micro from ATMEL combine Advance RISC performance, low-cost, and from small
to HUGH ROM size like the MegaAVR and a complete selection of the number of I/O's
to suite a variety of applications that requires the best price/performance ratio
in the industry.
ATMEL offers 3 family of AVR MCUs to best fit your needs, namely : -
the AVR Tiny in a 8-pin package, the standard AVR, and the MegaAVR.
All families offer reprogrammable FLASH ROM with low-voltage and low-power options,
with a variety of I/O options & peripheral options.
The AVR Tiny packs the powerful RISC-based AVR micro architecture into an
8-pin DIP or SOIC packages. These AVR Tiny products are available with
, a low operating voltage of 2.5V, small package
footprints, interrupt handling and a deeper hardware stack. All of these features
provide an intelligence level not previously available in applications because of cost
or size considerations.
