AT91M42800A
The Power Management Controller allows the user to adjust device activity according to system
requirements, and, with the 32.768 kHz low-power oscillator, enables the AT91M42800A to
reduce power requirements to an absolute minimum. The AT91M42800A is manufactured using
Atmel’s high-density CMOS technology. By combining the ARM7TDMI processor core with on-
chip SRAM and a wide range of peripheral functions including timers, serial communication con-
trollers and a versatile clock generator on a monolithic chip, the AT91M42800A provides a
highly-flexible and cost-effective solution to many compute-intensive applications.
