Description

The EC200 series is the second generation of controllers in the EJC product family. This module is a complete and versatile single board computer in SO-DIMM size with very high performance, ultra-low power consumption, industrial temperature range, and an impressive set of features and interfacing options.

The system is based on a 32-bit ARM720T processor running at 74 MHz. It features up to 64 MB SDRAM, up to 16 MB of NOR flash, and an optional onboard NAND flash which provides up to 256 MB of solid-state data storage. Onboard interfaces include Ethernet, serial ports, I2C, Dallas 1-wire, digital I/O, analog inputs, LCD, and an ISA-style expansion bus.

The integrated LCD controller can directly interface to most QVGA panels and supports up to 4096 colours onscreen. Connection of a touch screen controller is also possible. Along with the small size and low power consumption, this makes the EC200 ideal for portable and mobile applications.

The EC200 features a fully programmable slave microcontroller that can be used to extend the module's possibilities with new functionality, or to offload the main CPU by taking care of process-intensive I/O. This makes the system a perfect fit for hard real-time applications.

See the markets section for more potential applications.
