2 / 43 page LC75818PT No.A0964-2/43 Continued from preceding page. • Instruction function Display on/off control Display shift function • Sleep mode can be used to reduce current drain. • Built-in display contrast adjustment circuit • The frame frequency of the common and segment output waveforms can be controlled by instructions. • 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 Specifications Absolute Maximum Ratings at Ta = 25 °C, VSS = 0V Parameter Symbol Conditions Ratings Unit VDD max VDD -0.3 to +4.2 Maximum supply voltage VLCD max VLCD -0.3 to +11.0 V CE, CL, DI, INH -0.3 to +4.2 VIN1 CE, CL, DI, INH VDD=2.7 to 3.6V -0.3 to +6.5 VIN2 OSC, KI1 to KI5, TEST -0.3 to VDD +0.3 Input voltage VIN3 VLCD1, VLCD2, VLCD3, VLCD4 -0.3 to VLCD +0.3 V VOUT1 DO -0.3 to +6.5 VOUT2 OSC, KS1 to KS6, P1 to P4 -0.3 to VDD +0.3 Output voltage VOUT3 VLCD0, S1 to S80, COM1 to COM10 -0.3 to VLCD +0.3 V IOUT1 S1 to S80 300 μA IOUT2 COM1 to COM10 3 IOUT3 KS1 to KS6 1 Output current IOUT4 P1 to P4 5 mA Allowable power dissipation Pd max Ta=85 °C 200 mW Operating temperature Topr -40 to +85 °C Storage temperature Tstg -55 to +125 °C Allowable Operating Range at Ta = -40 °C to +85°C, VSS = 0V Ratings Parameter Symbol Conditions min typ max unit VDD VDD 2.7 3.6 VLCD When the display contrast adjustment circuit is used. 7.0 10.0 Supply voltage VLCD VLCD When the display contrast adjustment circuit is not used. 4.5 10.0 V Output voltage VLCD0 VLCD0 VLCD4 +4.5 VLCD V VLCD1 VLCD1 3/4 (VLCD0- VLCD4) VLCD0 VLCD2 VLCD2 2/4 (VLCD0- VLCD4) VLCD0 VLCD3 VLCD3 1/4 (VLCD0- VLCD4) VLCD0 Input voltage VLCD4 VLCD4 0 1.5 V Continued on next page. |
