Platform speeds SH-3 applications development

The EDOSK7705 is a low-cost high-integration OS reference platform for the SH7705 32bit microprocessor.

The EDOSK7705 is a low-cost high-integration OS reference platform for the SH7705 32bit microprocessor.

The platform offers a wide range of interfaces and connectors and is supplied with a free Linux board support package (BSP).

It can speed the development of SH-3 applications based on an embedded OS such as Linux, reducing time to market with the SH7705 device.

The EDOSK7705 includes 16Mbyte of SDRAM, 8Mbyte of Intel Strata Flash and a CPLD for user flexibility.

It offers a number of interfaces including: a USB 1.1 function interface, which supports full-speed (12Mbit/s) USB transfer modes; a full duplex serial interface with a 64byte buffer; an Ethernet 10Base-T interface to a LAN, which is provided by means of a RG45 connector; and an IrDA 1.0 interface with a 64byte buffer for transmit and receive operations.

The platform also includes a software bootloader to enable code download over serial or Ethernet.

It supports all seven clock operating modes of the SH7705.

The platform offers a range of connectors including: an auxiliary expansion connector to interface with all unused peripherals and I/O signals; a local bus expansion connector to interface with expansion boards that require connection to unbuffered signals (eg SDRAM expansion boards); a buffered expansion connector for expansion boards other than those that need connection to the local bus; an H-UDI connector for interfacing to an on-chip debugger; and an optional AUD connector for trace capture.

EDOSK7705 is compatible with all Renesas Solution Engine daughtercards offering rapid prototyping of complete systems, including graphics, Firewire and Bluetooth.
