The ESK-303 provides you with a fully functional development and prototyping platform for the Holtek 8-bit Flash MCU HT66F2390. The board contains an embedded e-Link Lite which assists users to quickly get started to evaluate the HT66F2390 functions and features, thus providing a means for high efficiency and low risk product prototype design.
This starter kit mainly has two functions: OCDS function and ICP function. The OCDS (On-Chip-Debug-Support) function is useful for program development and debugging, it works with the HT-IDE3000 software. The ICP (In-Circuit-Programming) function is used to program to the HT66V2390 MCU on the board. It works with the HOPE3000 for e-Link software.
The board has embedded two parts of electronic circuits: the e-Link Lite and the HT66V2390 system board. The e-Link Lite is a simplified version of
e-Link which is a debug adaptor. It can be used independently for other Holtek 8-bit Flash MCU device OCDS and ICP functions. The e-Link Lite should be separated to avoid signal interference. The HT66V2390 system board is a small HT66F2390 system. The headers on the board contain all I/O pins for user expansion.
A mini USB connector on the e-Link Lite can be used to power the entire development board, but the power is supplied to the HT66V2390 system board only when the HT-IDE3000 is running at full speed. The VDD and GND pins on the board can be used to power the HT66V2390 system board independently.
