Ledato SAMDIP-7X



SAMDIP-7X is a small microprocessor ARM7 board designed to be as simple as possible to use. It contains a low-power, high-performance ARM7TDMI processor core with a large variety of peripherals and needs as less as possible of external components.

As data encryptions has become more and more important, SAMDIP-7X as a good choice for secure applications. It contains a hardware data encryption unit that is able to en- and decript data parallel to code execution. For development purpose SAMDIP-7X is also available as debug version.

SAMDIP-7X: ARM7 board with AT91SAM7XC256 CPU

The Starter kit SAMDIP-7X evaluation board is the perfect interface for development and hardware designs including the SAMDIP-7X.

To access all the IO pins the processor offers in a simple way SAMDIP-7X is designed as standard 64 pin DIP package to be easily integrated in every circuit. It's great range of peripheral interfaces makes it suitable for any application by providing USB 2.0 at 12 Mbit per second, 10/100 Mbit Ethernet, TWI, SPI, CAN and very flexible USART that support RS485, IrDA, ISO7816 as well as Manchester Encoding.

For security issues in a networking environment or save data transfers over the internet SAMDIP-7X provides hardware encryption and decryption with 128-bit AES and TDES.

A fast on-board DMA controller cares about data transfers from or to these devices conserving processor capacities. Eight ADC channels and a PWM unit allow interaction with additional hardware. The ARM7 board is available with 64/32 KB SRAM and 256/128 KB Flash.

Programs can, according to the applications's memory requirements, be either executed in Flash or, for better performance, in SRAM. Atmels integrated SAM-BootAssistant (SAM-BA) alleviates programming of SAMDIPs Flash memory (find more information in our manual). Programs can be written in C using WINARM for example.

For testing and development but also for products the Starter kit SAMDIP-7X evaluation board is perfectly suited. It contains the needed circuits for USB, Ethernet, RS232C and power supply and offers room for own circuits and a self defined 26 pin DSUB port. The USART are available at two male DSUB connectors whose pin assignments are configurable by jumpers. The 64 pin socket allows the easy replacement of SAMDIPs so this board can also be used as programming board. Two switches and three coloured LEDs are disposable for testing.
