7/6/2004 - Renesas Technology Corp. announced, a low-priced on-chip debugging emulator1 dubbed "E8 Emulator" as a development tool for the R8C/14, R8C/15, R8C/16, and R8C/17 20-pin version Groups in the R8C/Tiny Series of small, low-pin-count 16-bit microcomputers. Sample shipments will begin on July 30, 2004 in Japan.
This emulator inherits the emulation functions and ease of use of the current E7 Emulator low-priced development tool. Features of the E8 Emulator are summarized below.
In the area of debugging of systems using a microcomputer, there has lately been a growing demand for on-chip debugging that allows debugging to be carried out with the microcomputer embedded in the user system. In the case of 8-bit and 16-bit microcomputers, in particular, system prices are not so high, and there is a strong need for a low-priced emulator.
In response to this need, Renesas Technology earlier released the E7 Emulator, priced significantly lower than previous emulators, for 32-pin models in the R8C/Tiny Series of small, low-pin-count 16-bit microcomputers, and is now releasing the E8 Emulator for the even lower pin-count R8C/Tiny Series R8C/14, R8C/15, R8C/16, and R8C/17 20-pin version Groups.
The E8 Emulator is an on-chip debugging emulator offered at a price within reach of the individual user.
Bidirectional communication between an R8C/14, R8C/15, R8C/16, or R8C/17 Group microcomputer and the emulator is handled by a single wire, employing an unused pin in the user system, enabling system debugging to be carried out in a state close to actual operation, which in turn helps to shorten development times. The use of only one signal line for debugging purposes also alleviates additional debugging design restrictions in the user system design process.
A Windows compatible PC can be used as the host computer, connected via a USB V1.1/V2.0 (Full Speed) interface allowing high-speed serial communication. Operation is in bus-powered mode using the USB power supply, allowing simple connection with no need for a special E8 Emulator power cable.
HEW is used for the user interface, linking together a variety of software including a C++ compiler, debugger, and linker. This allows efficient program development by controlling various tasks from programming to building and debugging via an integrated man-machine interface.
A flash writer function is also included, enabling the user to write a program to the microcomputer's on-chip flash memory as soon as program debugging is completed.
The user interface is implemented via a 14-pin connector compatible with the current E7 Emulator, allowing direct use of third-party products and user systems equipped with an E7 Emulator interface.
E8 Emulator support for the R8C/Tiny Series R8C/10, R8C/11, R8C/12, and R8C/13 Groups and the M16C/Tiny Series is scheduled for the future, and support for the H8/Tiny Series is also in the planning stage.
