AT91FR40162S-CU

Product Summary

The AT91FR40162S-CU is a member of the Atmel AT91 16/32-bit Microcontroller family, which is based on the ARM7TDMI processor core. The processor of the AT91FR40162S-CU has a high-performance 32-bit RISC architecture with a high-density 16-bit instruction set and very low power consumption. The AT91FR40162S-CU 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 of the AT91FR40162S-CU enables a performance of up to 74 MIPs in typical conditions with significant power reduction and EMC improvement over an external SRAM implementation. The Flash memory may be programmed via the JTAG/ICE interface or the factoryprogrammed Flash Memory Uploader (FMU) using a single device supply, making the AT91FR40162S-CU suitable for in-system programmable applications.
