Ordering number : ENN6144A CMOS IC LC75817NE, 75817NW 1/8 to 1/10 Duty Dot Matrix LCD Display Controllers/Drivers with Key Input Function Overview The LC75817NE and LC75817NW are 1/8 to 1/10 duty dot matrix LCD display controllers/drivers that support the display of characters, numbers, and symbols. In addition to generating dot matrix LCD drive signals based on data transferred serially from a microcontroller, the LC75817NE and LC75817NW also provide on-chip character display ROM and RAM to allow display systems to be implemented easily. These products also provide up to 4 general-purpose output ports and incorporate a key scan circuit that accepts input from up to 30 keys to reduce printed circuit board wiring. • • • • • • • • Sleep mode can be used to reduce current drain. Built-in display contrast adjustment circuit Up to 4 general-purpose output ports are included. Serial data I/O supports CCB format communication with the system controller. Independent LCD driver block power supply VLCD A voltage detection type reset circuit is provided to initialize the IC and prevent incorrect display. The INH pin is provided. This pin turns off the display, disables key scanning, and forces the general-purpose output ports to the low level. RC oscillator circuit Features • Key input function for up to 30 keys (A key scan is performed only when a key is pressed.) • Controls and drives a 5 × 7, 5 × 8, or 5 × 9 dot matrix LCD. • Supports accessory display segment drive (up to 60 segments) • Display technique: 1/8 duty 1/4 bias drive (5 × 7 dots) 1/9 duty 1/4 bias drive (5 × 8 dots) 1/10 duty 1/4 bias drive (5 × 9 dots) • Display digits: 12 digits × 1 line (5 × 7 dots, 5 × 8 dots) 11 digits × 1 line (5 × 9 dots) • Display control memory CGROM: 240 characters (5 × 7, 5 × 8, or 5 × 9 dots) CGRAM: 16 characters (5 × 7, 5 × 8, or 5 × 9 dots) ADRAM: 12 × 5 bits DCRAM: 48 × 8 bits • Instruction function Display on/off control Display shift function • CCB is a trademark of SANYO ELECTRIC CO., LTD. • CCB is SANYO’s original bus format and all the bus addresses are controlled by SANYO.
