Digi International's ConnectCore embedded core modular products based on NetSilicon's ARM7 and ARM9 processor cores enable users to easily design in main processing functionality with fully integrated Ethernet networking capabilities.

Based on NetSilicon's NS7520 processor, the ConnectCore 7U is the product family's first ARM7-based NET+ARM core processor module. Both the ConnectCore 9P 9360 and ConnectCore 9P 9750 modules are built on NetSilicon's ARM9-based NET+ARM processors, while the ConnectCore 9P 9750 offering has an on-chip PCI v2.2 bus interface.

The ConnectCore 7U comes in a compact 48-pin dual-inline package form factor. It offers 16MB of RAM and up to 8MB of on-board flash memory, an integrated 10Mb/100Mb Ethernet MAC/PHY and configurable UART/SPI ports. It also features an I2C bus software interface, 16 shared GPIO ports for application-specific use, and an external 10-bit address/8-bit data bus interface for added component integration.

"Our expanded ConnectCore product family is ideal for product designs demanding virtually any level of performance, connectivity and development platform flexibility. These modules are targeted for products including, access control systems, point-of- sale systems, RFID readers, medical devices and instrumentation, networked displays and many more," said Steve Ericson, director, product management, Digi International.

In addition to leveraging Digi's NET+OS and uClinux development platforms, ready-to-run application-focused development kits for Java, serial LCD integration, CAN bus communication, Bluetooth connectivity, CompactFlash/WLAN support and biometric fingerprint reading are available for the ConnectCore 7U modules.

The ConnectCore 9P modules combine ARM9-based NET+ARM processor performance and integrated peripherals such as 10/100 Mbit Ethernet, UART and SPI ports, USB 1.1/2.0 host/device connectivity, and an integrated LCD controller for TFT/STN displays. The modules include up to 128MBytes of on-board SDRAM and flash memory in a module form factor. The ConnectCore 9P modules support the ThreadX-based NET+OS environment, Microsoft Windows CE or Linux.

"Our common embedded software platform and development tool offering reduces embedded product design by up to 50 percent," Ericson added. "It also allows customers to utilize the same design across multiple product lines and technologies. This minimizes development time and cost, and offers customers a seamless migration path to a fully integrated and cost-effective product design based on the NetSilicon NET+ARM family of processors." ConnectCore 7U and ConnectCore 9P modules and development kits are available now.

The Connectcore 7U are priced from $72 in 1,000 annual quantities, and the ConnectCore 9P are priced from $155 in 1,000 annual quantities.
