DM1623_ SANYO 16 Characters x 2 Lines Liquid Crystal Dot Matrix Display Module Preliminary Overview General Specifications The DM1623 is an LCD dot matrix display module that 1. Drive method: 1/16 duty, 1/5 bias (1/4 bias for the consists of an LCD panel and controller/driver circuits. STN version) It is capable of displaying two lines of 16 characters. 2. Display size: 16 characters x 2 lines The DM1623 module incorporates the control circuits, 3, Character structure: 5 x 8 dots data RAM, and character generator ROM required for 4. Display data RAM: 80 characters (80 x 8 bits) display. The DM1623 provides both 8-bit and 4-bit 5, Character generator ROM: 192 characters parallel interfaces, and allows the controlling (See table 1.) microprocessor to read and write data directly. 6. Character generator RAM: 8 characters (64 x 8 bits) 7. Instruction function: See table 2, 8. Circuit structure: See the block diagram.
