Description

The AT91M43300 is a member of the Atmel 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 features 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.

The AT91M43300 has a direct connection to off-chip memory, including Flash,

through the fully-programmable External Bus Interface.

The AT91M43300 is manufactured using Atmel’s high-density CMOS technology. By

combining the ARM7TDMI microcontroller core with an on-chip SRAM, and a wide

range of peripheral functions on a monolithic chip, the AT91M43300 provides a highly-

flexible and cost-effective solution to many compute-intensive multi-processor appli-

cations.

The compact BGA package reduces required board space to an absolute minimum.
