The AT91SAM9260 is the first member of Atmel’s pincompatible ARM9-based microcontroller family that shares the same programming model as ARM7-based devices, allowing direct migration between devices based on different ARM cores. This microcontroller also supports deterministic, real-time operation, offers supervisory functions, and has third-party RTOS support comparable to those of 8-bit MCUs. Subsequent members of the AT91SAM9 family will incorporate on-chip Flash memory.
Developed for highly-connected image processing applications, such as point-of-sale terminals, Ethernet-based IP cameras, and bar code readers, the AT91SAM9260 integrates a 200MIPS ARM926EJ-S processor with a camera interface, seven USARTs, 10/100 Ethernet MAC, 12Mbps USB device and host controller with on-chip transceivers, external bus interface supporting SDRAM, Flash, NAND Flash with built-in ECC, SD, SDIO, and multimedia card interface (MMC), three synchronous serial controllers (SSC), two master/slave serial peripheral interfaces (SPI), a three-channel 16-bit timer/counter, two-wire interface (TWI) and IEEE 1149.1 JTAG Boundary Scan on all digital pins.
