1. Overview
1.1 Features
The Reference Board is for learning how to use the ML620Q150A Series of microcontrollers, on which adding
external user components if necessary. Using the Reference Board with LAPIS Semiconductor's on-hip debug
emulator uEASE delivered with the software development environments, help user's software development and
debugging and programming the Flash.
1.1.1 Board features
The board delivered with ML620Q150A series microcontroller or one of 48pin TQFP/ 52pin TQFP/ 64pin TQFP
socket.
Available functions of programming the Flash ROM and on-chip debugging the software (P14/TEST0 and TEST1_N
are used for the communication).
Through-holes for connecting the pins of microcontroller to external pheripheral boards.
The power supply is selectable, supplied from the on-chip debug emulator uEASE or an user pheripheral board.
Pads for mounting components, useful for evaluating the microcontroller.
EVA Board is available to be connected to the Reference Board, which has a RS232C connector and external
components, useful when evaluating ISP function or A/D converter.
1.1.2 Hardware specifications
See the schematic on page 22 to 26 for more detail about connection of the mounted components.
