Technical Manual
Notes
1. D0 to D7, A0, CS, RD, WR, VD0 to VD7, VA0 to VA15, VRD, VWR and VCE are TTL-level inputs.
2. SEL1 is CMOS-level inputs. YD, XD0 to XD3, XSCL, LP, WF, YDIS are CMOS-level outputs.
3. RES is a Schmitt-trigger input. The pulsewidth on RES must be at least 200
s. Note that pulses of more than a few seconds will
cause DC voltages to be applied to the LCD panel.
4.
fOSC = 10 MHz, no load (no display memory), internal character generator, 256
× 200 pixel display. The operating supply current can
be reduced by approximately 1 mA by setting both CLO and the display OFF.
5. VD0 to VD7 and D0 to D7 have internal feedback circuits so that if the inputs become high-impedance, the input state immediately
prior to that is held. Because of the feedback circuit, input current flow occurs when the inputs are in an intermediate state.
6. Because the oscillator circuit input bias current is in the order of
A, design the printed circuit board so as to reduce leakage currents.
VDD = 2.7 to 4.5 V, VSS = 0 V, Ta = –20 to 75C unless otherwise noted
