1. Description
The AT91M43300 is a member of the Atmel AT91 16/32-bit Microcontroller family which is based on the ARM7TDMI pro-
cessor 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 microcon-
troller 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 applications.
The compact BGA package reduces required board space to an absolute minimum.
