Sealevel R91001-SBC ARM9 Embedded RISC Computer

The Sealevel R91001-SBC delivers RISC computing power with a wealth of I/O features and uses the latest embedded software environment.

The Sealevel R91001-SBC is an application-ready platform for your next product design. The system is based on the 200MIPS Atmel AT91SAM9263 microcontroller boasting a 32-bit ARM instruction set for maximum performance. With up to 256MB RAM and 256MB Flash memory, the unmatched I/O features of the SBC-R9 extend the possible uses beyond traditional ARM applications. The SBC-R9 is the perfect platform for embedded applications requiring small size, wide operating temperature range, and flexible I/O connectivity.

Standard I/O includes Ethernet, serial, USB, CAN bus, digital and analog interface. System designers can directly drive TFT/STN LCDs from the onboard video controller, and the board also includes a resistive touchscreen controller, making it perfect for human-machine interface applications.

To provide the fastest time to market, the Windows CE 6.0 BSP binary and low-level drivers for system I/O are included. Additionally, the SBC-R9 software package is equipped with the Sealevel Talos I/O framework, which offers a high-level, object-oriented .NET Compact Framework (CF) device interface. This interface provides an I/O point abstraction layer with built-in support for the specific needs of analog and digital I/O such as gain control and debouncing.

For embedded Linux systems, Sealevel provides fully configurable components – cross-compilation toolchain, bootloader, kernel, and root filesystem – using a customized BuildRoot with Sealevel patches, additional features, and source code samples.

Measuring just under 7.5 x 5.0 in size, the SBC-R9 is small enough to fit in most embedded applications and is rated for a full -40°C to 85°C operating temperature range. The SBC-R9 is powered from your 7-30VDC source, or select from a variety of Sealevel power supply options.

A QuickStart development kit is available, which includes the most common accessories. For applications with specialized hardware requirements, developers can use the SBC-R9 as a platform for application development while Sealevel designs a customized target system specific to the user’s application requirements.
