Triscend is a provider of configurable system-on-chip (CSoC) devices for the communications sector that include a dedicated microprocessor, embedded programmable logic, a dedicated system bus, and system memory. The CSoC device can be combined with intuitive software to create a customised processing platform for communications and embedded system applications.
To help develop designs based on its 8bit E5 CSoC devices the company has developed a modular development kit that can be expanded to meet the needs of individual projects.
Available together or as separate components the two part development kit consists of a CSoC evaluation board supported by a base board which can be extended with add-on prototyping and application specific boards.
The E5 evaluation kits provides an alternative to the full development kit and contains a evaluation board and TE520 chip supported by memory, I/O and communication facilities. The kit also includes power supply, download/debug cable and a full FastChip design software license.
To safeguard programme code and CSoC configuration, the evaluation board is equipped with a 128kbyte Flash memory to back up the TE520's internal SRAM, and a serial EEPROM socket as a further alternative.
Integral push button DIP switches and dual seven segment LED display provide external application stimuli.
A JTAG interface enables programme debug and download over a standard parallel cable while an RS232C channel is also included to provide a serial communications capability. The board is clocked by a 40MHz oscillator.
With the E5 base board upgrade kit users can move from the evaluation kit level to the complete development kit. Plugging the evaluation board straight into the base board provides instant access to an additional 256kbyte of external Flash and SRAM, a 16 x2 alphanumeric LCD additional switches and LEDs and two more RS232 ports.
A prototyping expansion board is included in the upgrade kit and is plugged in via one of the base boards three 96pin expansion slots to enable additional circuitry to be added around the standard E5 development platform.Application specific development boards, such as the graphic LCD interface board, are attached in the same way.
