Arrow Electronics has introduced a system-on-module (SoM) package that will provide engineers with quick-and-easy access to the full functionality of the ARM Cortex-A5 microcontroller core. The AT-501 SoM was developed by Arrow in conjunction with Shiratech, Israel.

It utilises an Atmel SAMA5D3 ARM Cortex-A5 based MCU and combines high performance and low-power consumption with an extensive range of peripheral support. This makes it particularly suitable as a platform for developing mobile and battery-powered embedded systems that demand minimal energy usage in order to achieve extended periods of operation.

The new module helps shorten development cycles and reduce cost and risk by allowing users to focus on their own Intellectual Property (IP). In addition to the processing unit, it comes complete with 256 MB DDR2 and flash memory, a built-in 1G Ethernet, an internal system clock and a 200-pin SO-DIMM connector via which all the supported interfaces are available. The SoM measures 68 x 47mm and uses a single 3.3V power input.

Boot and operating system software is supplied, including the Debian Linux distribution and in versions for internal flash and SD card, together with software support for available interfaces. Sample applications for web server, CLI and SNMP agent and a software package for secured software upgrade and version control are also available. Integration is further simplified by a configuration tool that defines pin-outs. A Linux OS and tools is also available from Timesys.

A companion evaluation board (CB-20) is also available. This incorporates a seven-inch TFT LCD with four-wire resistive touch screen; MicroSD card slot; dedicated debug port with RS232-to-USB converter; JTAG interface; and audio interface.
