AT91SAM7 Flash Microcontrollers

Microchip Technology AT91SAM7 Flash Microcontrollers (MCUs) are based on the 32-bit ARM7TDMI® RISC processor. Microchip AT91SAM7L MCUs are ultra-low power devices embedding power switches controlling multiple power islands and programmable voltage regulators to reduce power consumption in active and standby modes. A91SAM7S MCUs feature up to 512K bytes of embedded high-speed Flash of high-speed Flash and up to 128K of SRAM, a large set of peripherals, including an 802.3 Ethernet MAC, and a CAN controller. A complete set of system functions minimizes the number of external components.
