If you need more pins and a 240x64 GLCD with T6963C (Toshiba) for your prototype device than the Serial GLCD 240x64 Adapter Board is the best choice. It is connected to a 240x64 GLCD via an on-board serial port expander MCP23S17 that uses SPI.
The Serial GLCD 240x64 Adapter Board enables you to connect your T6963C (Toshiba) 240x64px GLCD easily and save MCU pins. A 16-bit I/O expander MCP23S17 is provided on the board thus decreasing the number of MCU pins needed for running this display. Expander features SPI(tm) clock speeds up to 10MHz for higher throughput applications.
