| ABRIDGED EV KIT DATA SHEET DS5250 Evaluation Kit The DS5250 evaluation kit EV is a proven platform to conveniently evaluate the capabilities of the DS5250 high-speed secure microcontroller. It contains the microprocessor, 1MB of battery-backed SRAM, 1MB flash memory, a power-supply regulator, two DB-9 serial connectors, and switches and LEDs to control and display board operation. With the addition of a power supply and an RS-232 cable connected to a personal computer, the kit provides a completely functional system ideal for evaluating the capabilities of the DS5250. The evaluation board allows the user to easily load and execute code on the DS5250 processor. The kit is delivered with a customized Keil Software debugger that can be used to debug application code prior to availability of the end target hardware. Schematic diagrams for the board are also included to provide a convenient reference design go to The DS5250 processor is ideal for applications requiring a trusted computing environment for private or secret information such as card terminals, PIN pads, access control units, and similar applications.
