Development and on-chip debut package for Hitachi's Tiny series

17 July 2002 DSP, Micros & Memory

Hitachi's LEM3664 emulation module is the first in a series of development tools supporting the company's H8/300H Tiny series E10T on-chip debug interface. The module provides a complete set of tools for this family of microcontrollers, including a fully functional version of the Tiny series C compiler.

LEM3664 incorporates a USB interface and cable, a target connector and an on-board 16 MHz H8/3664H microcontroller, providing EVB-like facilities. It has three modes of operation: standalone EVB mode; E10T mode, using the target connector; and emulator mode, using a built in mini-dip header or external QFP header.

The E10T debug interface supports a high-speed serial link between the microcontroller and LEM3664. Each Tiny series microcontroller also has an on-chip breakpoint controller and trace buffer which allow applications to be downloaded to the flash memory and debugged in the users target application.

The LEM3664 module supports the Hitachi Debug Interface (HDI), a Windows-based source level debugger, allowing applications to be debugged at both C and assembly level. HDI allows access to LEM3664 features, including C watch points, C and instruction level trace, breakpoints and flash programming, using Windows 98 or 2000. The emulation module also comes with a full C compiler for the Tiny Series and the Hitachi Embedded Workshop (HEW) development enviroment.

Software upgrades will extend the support of the emulation module to other members of the Tiny series family including H8/3672F, H8/3687F and H8/3694F microcontrollers.
