Real-Time ARM9 MCU Supports Migration From ARM7
San Jose, California (ots/PRNewswire)
- Integrates Ethernet MAC, 7 USARTs, USB 2.0 Host and Device, Camera Interface
Atmel(R) Corporation (Nasdaq: ATML), announced today the AT91SAM9260, the first member of a pin-compatible ARM9(TM)-based microcontroller family that shares the same programming model as ARM7(TM) based controllers, allowing direct migration between controllers based on different ARM(R) cores. The AT91SAM9260 also supports deterministic, real-time operation, offers supervisory functions, and has third-party RTOS support comparable to those of 8-bit controllers.
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 200 MIPS ARM926EJ-S(R) core with a camera interface, seven USARTs, 10/100 Ethernet MAC, 12 Mbps 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(R) 1149.1 JTAG Boundary Scan on all digital pins.
The internal bus bandwidth of the AT91SAM9260 is maximized by 24 DMA channels and a five-layer high-speed bus matrix. It connects all masters and slaves in the system in a parallel fashion and enables data transfers between peripherals and on- and off-chip memories without any CPU intervention. A programmable arbiter manages the priorities between the bus masters. Highly critical interrupt routines can be locked in the 16 kByte instruction cache guaranteeing a deterministic response time to interrupts. A system controller provides a full complement of supervisory functions that includes an 8-level priority interrupt controller, RC-oscillator, PLLs, real-time periodic interval and watchdog timers, reset and shutdown controllers, and backup registers. The shutdown controller puts the processor in an ultra low power mode, typically less than 10 uA.
Third-party RTOS Support -- The AT91SAM9260 has third-party RTOS support from Green Hills(R) Software, Mentor Graphics(R) and Micrium. Compiler/debuggers are available from Green Hills Software, ARM, Keil(TM), IAR Systems and any compliant ARM926EJ-S compiler. Windows CE(R) and Linux(R) operating system support is also provided.
Packaging and Availability -- The AT91SAM9260 is available now in a 217-ball LFBGA RoHS-compliant package and in a 208-pin Green QFP package and is priced at or near US$6 in quantities of 100,000. Additional members of the SAM9 family will be available in late 2006 and 2007.
