AT91 Products Overview

2 The Atmel AT91 Series of microcontrollers are based upon the powerful ARM7TDMI processor. Atmel has taken these cores, added a wide range of peripherals and advanced power management systems, to give the design engineer the best of both worlds – a high performance peripheral set with very low power consumption. It gives the buyer a 32-bit processor at 16-bit cost! AT91 ARM-Based microcontroller
