Serial RAM
The Serial RAM additional board enables the microcontroller to use additional 64Kbit of RAM memory.
Key features:
How to connect the board?
The Serial RAM can be easily connected to a development system’s port via a 2x5 connector CN1. The additional
board may be connected to 3.3V and 5V development systems. If it is connected to a 3.3V development system, it is
necessary to place jumper J1 in the 3.3V position. Otherwise, this jumper should be left in the 5V position. The position
of switches on the DIP switch SW1 depends on the development system in use, Table 1.
How to use the board?
The Serial RAM additional board communicates with the microcontroller supplied on the development system via the
Serial Peripheral Interface (SPI). A LED marked POWER indicates that the additional board is turned on.
