Atmel Corp. has released five additions to its Atmel SAM9 ARM926-based MCU family. The SAM9 devices can be used in several applications including industrial and building control, HVAC, Point of Sale (POS) terminals, printers and medical devices, smart grid with data concentrators, human machine interfaces (HMI) and M2M market segments.

The SAM9G15, SAM9G25, SAM9G35, SAM9X25, SAM9X35 devices expand Atmel's existing ARM-based portfolio by supporting a range of key technology features required for today's applications. These features include replacing SDRAM with DDR2 memory for more memory-intensive applications; NAND flash support with 24bit ECC for reduced system cost; and more communication channels including dual 10/100 Ethernet, dual CAN and up to 3x USB ports for a variety of application requirements. Atmel has also teamed with Conexant to enable soft modem implementation on the SAM9 devices to lower the overall bill of materials (BOM) by eliminating external components. The five ARM926-based microcontrollers operate at up to 400MHz and the core and peripherals consume only 100mW at maximum performance.

The Atmel SAM9 devices also include an advanced graphics LCD controller with hardware acceleration for more modern user interfaces in today's industrial applications. The enhanced LCD controller includes overlays, alpha blending, image scaling, rotating and color space conversion to enable a more intuitive interface, while offloading the CPU.

The SAM9G15, SAM9G25, SAM9G35, SAM9X25, SAM9X35 are available now in a 0.8mm ball pitch 217-ball BGA package. The SAM9G25 also ships in a 0.5mm ball pitch 247-pin BGA package. Pricing starts at $6.10 in 1,000-piece quantities.
