The SerialRAM Board features an 8192-byte Serial SRAM 23K640 designed to communicate with a microcontroller via Serial Peripheral Interface (SPI). It also may communicate with a microcontroller that doesn't have a built-in SPI port by using discrete I/O lines. The board features voltage translators that enable connection with systems operating at different voltage levels.
The board has a female IDC10 connector to plug it into a development system. It communicates with the host system via SPI. The DIP switch allows you to set which pins are used for MISO/MOSI/SCK, and the silkscreen explains the settings required for specific MikroElektronika development systems that have a matching IDC10 header. A jumper setting allows you to set this board to work with 3.3V or 5V systems.
Use in your own design While this board was created originally for mikroElektronika's development systems, it's certainly possible to use in your own project. To do so, you may want to pick up IDC10 box headers that you can solder onto your PCB, or an EasyTEST board to wire it up easily.
