Ordering number : ENN5066B CMOS IC LC75854E, 75854W 1/4 Duty LCD Display Drivers with Key Input Function Overview The LC75854E and LC75854W are 1/4 duty LCD display drivers that can directly drive up to 164 segments and can control up to four general-purpose output ports. These products also incorporate a key scan circuit that accepts input from up to 30 keys to reduce printed circuit board wiring. Features • Key input function for up to 30 keys (A key scan is performed only when a key is pressed.) • 1/4 duty - 1/2 bias and 1/4 duty - 1/3 bias drive schemes can be controlled from serial data (up to 164 segments). • Sleep mode and all segments off functions that are controlled from serial data • Segment output port/general-purpose output port function switching that is controlled from serial data • Serial data I/O supports CCB format communication with the system controller. • Direct display of display data without the use of a decoder provides high generality. • Provision of an on-chip voltage-detection type reset circuit prevents incorrect displays. • RC oscillator circuit Package Dimensions unit: mm 3159-QFP64E 1.0 48 49 [LC75854E] 17.2 14.0 1.6 0.8 0.35 1.0 33 32 0.15 17.2 14.0 1.6 1.0 0.8 1.0 3.0max 64 1 17 16 0.1 2.7 unit: mm 3190-SQFP64 15.6 0.8 SANYO: QFP64E 1.25 48 49 [LC75854W] 12.0 10.0 0.5 0.18 1.25 33 32 0.15 12.0 10.0 0.5 1.25 64 1 17 16 0.1 1.7max 1.25 • 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. 0.5 0.5 SANYO: SQFP64 Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft’s control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage.
