AT91M40400 Datasheet 16/32-bit Microcontroller

Manufacturer: Atmel (now Microchip Technology)

General Description

The AT91M40400 is a member of the Atmel AT91 16/32-bit Microcontroller family which is based on the ARM7TDMI embedded processor.

This processor has a highperformance 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.

Key Features

  • Incorporates the ARM7TDMI ™ ARM Thumb processor.
  • High-performance 32-bit RISC architecture.
  • High-density 16-bit instruction set.
  • Leader in MIPS/Watt.
  • Embedded ICE In Circuit Emulation 4K bytes internal RAM Fully programmable External Bus Interface (EBI).
  • Maximum external address space of 64M bytes.
  • Up to eight chip selects.
  • Software programmable 8/16-bit external databus Eight-level priority, individually maskable, vectored.
