AT91M42800A-33AU 产品描述

The AT91M42800A is a member of theAtmel AT91 16/32-bit microcontroller family, which is based on the ARM7TDMI processor core. This processor has a high-performance 32-bit RISC architecture with a high-density 16-bit instruction set and very low power consumption. In addition, a large number of internally banked registers result in very fast exception handling, making the device ideal for real-time control applications. The AT91 ARM-based MCU family also features Atmel’s high-density, in-system programmable, nonvolatile memory technology.

TheAT91M42800A has a direct connection to off-chip memory, including Flash, through the External Bus Interface. 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 theAT91M42800A to reduce power requirements to an absolute minimum.

TheAT91M42800A 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 controllers and a versatile clock generator on a monolithic chip, the AT91M42800A provides a highly flexible and cost-effective solution to many compute-intensive applications.
