The modules are targeted at applications such as networked displays, medical devices, building access controls, energy management devices, time and attendance devices, and scales, says Minnetonka, Minn.-based Digi. The products are the latest in a line of ConnectCore modules, including the ConnectCore 9P 9215 series, which shipped last year with Digi's own NS9215 processor.

The 9M 2443 modules are based on the Samsung S3C2443 ARM9 system-on-chip (SoC) and run at 400MHz or 533 MHz. Launched in 2003, the widely used S3C2440 series integrates 16KB each of instruction and data cache, 4KB RAM, a NAND flash boot loader, power management functions, an interrupt controller, and an external memory controller. The 9M 2443 series modules are supplied with 64MB to 256MB of mobile DDR, and 128MB to 1GB of NAND flash.

The ConnectCore 9M 2443 series is touted as "33 percent faster than any other ARM9-based core module." This is apparently due to what Digi describes as a multilayered memory bus architecture, enabling simultaneous data transfer between processor, memory, and peripherals. The architecture reduces bandwidth bottlenecks, so tasks such as updating graphical information via the LCD controller and retrieving data from memory can be performed simultaneously without a performance hit, claims the company.

In addition to the aforementioned LCD controller, peripheral options include Ethernet, USB 2.0 host and device, SD memory cards, mass storage, camera, and audio codecs interfaces. In addition, the Wi-9M 2443 offers an 802.11a/b/g interface. The modules are also said to provide off-the-shelf hardware and software support for all power management modes, enabling mobile, battery-powered devices.

The ConnectCore 9M 2443 has been tested and granted the European CE mark for compliance with safety standards, and the Wi-9M 2443 model will be certified upon availability, says the company. Both modules are said to offer a five-year manufacturer's warranty.
