    The AT91FR40162S is a member of the Atmel AT91 16/32-bit Microcontroller family, which is based on the ARM7TDMI processor core. The processor has a high-performance 32-bit RISC architecture with a high-density 16-bit instruction set and very low power consumption.
    The AT91FR40162S ARM microcontroller features 2 Mbits of on-chip SRAM and 2 Mbytes of Flash memory in a single compact 121-ball BGA package. Its high level of integration and very small footprint make the device ideal for space-constrained applications. The high-speed on-chip SRAM enables a performance of up to 74 MIPs in typical conditions with significant power reduction and EMC improvement over an external SRAM implementation.
