SAM7-EX256

开发板和工具包 - ARM DEV BRD FOR AT91SAM7X256

The is a development board for AT91SAM7X256 ARM7TDMI-S microcontroller. The AT91SAM7X256 is a member of a series of highly integrated flash microcontrollers based on the 32bit ARM RISC processor. It features 256Kbyte high speed flash and 64Kbyte 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. By combining the ARM7TDMI processor with on chip flash and SRAM, and a wide range of peripheral functions, including USART, SPI, CAN controller, Ethernet MAC, timer counter, RTT and analog to digital converters on a monolithic chip, the AT91SAM7X256 is a powerful device that provides a flexible, cost effective solution to many embedded control applications requiring communication over Ethernet, USB, CAN and RS 232.
