    The AT91FR4042 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 AT91FR4042 ARM microcontroller features 2 Mbits of on-chip SRAM and 4 Mbits 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 63 MIPs and significant power reduction over an external SRAM implementation.The Flash memory may be programmed via the JTAG/ICE interface or the factory-programmed Flash Uploader using a single device supply, making the AT91FR4042 suitable for in-system programmable applications.
