AT91SAM9260B-CU 描述

The AT91SAM9260 is the first member of a pin-compatible ARM9-based microcontroller family that shares the same programming model as ARM7-based controllers, allowing direct migration between controllers based on different ARM cores. It supports deterministic, real-time operation, offers supervisory functions, and has third-party support comparable to that for 8-bit microcontrollers.

The AT91SAM9260 is based on the ARM926EJ-S processor, with 8K byte instruction and 8K byte data cache memories. It operates at 210 MIPS with a 190 MHz clock. It features 8K bytes of SRAM and 32K bytes of ROM with single cycle access at maximum processor or bus speed, together with an external bus interface with controllers for SDRAM and static memories including NAND Flash and CompactFlash. Its extensive peripheral set includes USB Full Speed Host and Device interfaces, a 10/100 Base T Ethernet MAC, Image Sensor Interface, Multimedia Card Interface (MCI), Synchronous Serial Controllers (SSC), USARTs, Master/Slave Serial Peripheral Interfaces (SPI), a three-channel 16-bit Timer Counter (TC), a Two Wire Interface (TWI) and four-channel 10-bit ADC. Three 32-bit Parallel I/O Controllers multiplex the pins to/from these peripherals in order to reduce the device pin count, and peripheral DMA channels maximize the data throughput between these interfaces and the on- and off-chip memories. The AT91SAM9260 has a fully featured system controller for efficient system management, including a reset controller, shutdown controller, clock management, advanced interrupt controller (AIC), debug unit (DBGU), periodic interval timer, watchdog timer and real-time timer. It is available in a 217-ball LFBGA RoHS-compliant package and in a 208-pin Green QFP package. The AT91SAM9260 is supported by the AT91SAM9260 Evaluation Board and extensive third-party application development tools. It supports both Linux and Windows CE. It has been developed for highly connected image processing applications, such as point-of-sale terminals, Ethernet-based IP cameras, and bar code readers.
