AT91SAM9260集成电路（IC）的微处理器规格书PDF中文资料

Description

The AT91SAM9260 is based on the integration of an ARM926EJ-S processor with fast ROM and RAM memories and a wide range of peripherals. The AT91SAM9260 embeds an Ethernet MAC, one USB Device Port, and a USB Host control ler. It also integrates several standard peripherals, such as the USART, SPI, TWI, Timer Counters, Synchronous Serial Controller, ADC and MultiMedia Card Interface.
