Development for voice and data DSL equipment
The latest reference platform kit from Arrow Electronics simplifies the design, evaluation, prototyping and debugging of DSL-based equipment for use in SOHO environments.
Single-chip control of PC Card interfaces
Arrow Electronics has a family of compact, highly integrated and power-efficient PC Card controllers that will help designers to lower component count, save space and reduce power consumption.
During operation, the micro not only manages the USB interface but also uses its main Flash memory as the Flash disk storage.
The device's secondary Flash memory stores the micro firmware.
In addition to providing the "out of box" USB mass storage demonstration, the DK3420 also features a JTAG connector for debugging, allowing the board to be used as a flexible development platform.
With the appropriate tools, developers can compile a sample project, program the DK3420, and then debug the software by setting breakpoints, single-stepping C and assembly code, and using execution trace.
STMicroelectronics' uPSD3400 Turbo Plus devices are powerful 8051-based microcontrollers offering full-speed USB functionality and performance up to 10MIPS peak.
Main Flash memory options are 64, 128 or 256Kbyte, with secondary onboard Flash capacities of either 8 or 32Kbyte.
Additional memory comprises either 4 or 8Kbyte SRAM with battery backup, and onboard functionality includes I2C, UART, SPI and IrDA interfaces, an eight-channel 10bit ADC, and supervisory functions.
