PRODUCTION DATA
Required LCD connections greatly vary by the type of display that is used (static or multiplexed), whether external or internal biasing is used, and also whether the on-chip charge pump is employed. For any display used, LCD_E has configurable segment (Sx) or common (COMx) signals connected to the MCU which allows optimal PCB layout and for the design of the application software.
Because LCD connections are application specific, it is difficult to provide a single one-fits-all schematic. However, for an example of connecting a 4-mux LCD with 27 segment lines that has a total of 4 × 27 = 108 individually addressable LCD segments to an MSP430FR4133, see the MSP-EXP430FR4133 LaunchPad™ development kit as a reference.
