AT91SAM9263B-CU-100

微处理器 - MPU 32-bit MCU

Description AT91SAM9263B-CU-100

The AT91SAM9263 32-bit microcontroller, based on the ARM926EJ-S processor, is architectured on a 9-layer matrix, allowing a maximum internal bandwidth of nine 32-bit buses. It also features two independent external memory buses, EBI0 and EBI1, capable of interfacing with a wide range of memory devices and an IDE hard disk. Two external buses prevent bottlenecks, thus guaranteeing maximum performance.
