ATmega16

ATMEGA16 microcontroller is one of the popular controllers in AVR series. With its features and purchase cost it became one of favorite controller for both hobbyists and engineers. ATMEGA16 programming is similar to any other AVR controller. It is particularly a clone to ATMEGA32 except for the memory. Although it has only half the memory of ATMEGA32, it is still more than enough to satisfy most EMBEDDED SYSTEMS.

ATMEGA16 has also sleep modes. The modes can be triggered at desired times to save power. With various sleep modes on board ATMEGA16 can work on MOBILE EMBEDDED SYSTEMS.

ATMEGA16 has 32 programmable Input/output pins, with them ATMEGA16 can interface many peripherals easily.

ATMEGA16 has also programmable Watchdog Timer with Separate On-chip Oscillator. With this Watchdog timer to reset under error the controller can be used on applications where human interference in minimal.
