Microchip AT91R40008-66AU, 32bit ARM Microcontroller, AT91, 75MHz, 256 kB Flash, 100-Pin LQFP / 1773420

The AT91R40008 microcontroller is a member of the Atmel AT91 16/32-bit microcon- roller 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. Furthermore, it features 256K bytes of on-chip SRAM and a large number of internally banked registers, resulting in very fast excep- ion handling, and making the device ideal for real-time control applications.Incorporates the ARM7TDMI ® ARM® Thumb® Processor Core High-performance 32-bit RISC Architecture High-density 16-bit Instruction Set Leader in MIPS/Watt Little-endian EmbeddedICE™ (In-circuit Emulation) 8-, 16- and 32-bit Read and Write Support 256K Bytes of On-chip SRAM 32-bit Data Bus Single-clock Cycle Access Fully Programmable External Bus Interface (EBI) Maximum External Address Space of 64M Bytes Up to Eight Chip Selects Software Programmable 8/16-bit
