Preliminary
EM83040A
LCD CONTROLLER
GENERAL DESCRIPTION
The EM83040A is a dot matrix LCD driver which is fabricated by low power CMOS technology. This chip
includes 80- bits shift register , 80 bits data latch and 80 bits level driver. A LCD RAM inside can be mapping
to LCD signal. It converts RAM data to parallel data and output lcd waveform to LCD.
FEATURES
(1) Supply power 2.6~6V
(2) Internal RAM : 2.5k x 4 bits
(3) RAM can be controlled by eight signals including four bit data bus.
(4) LCD drive voltage :<13V
(5) Duty: 1/32, 1/48, 1/80
(6) Build in DC converter double and triple
(7) Modularized function: connect to another 83040 to extent LCD matrix
(8) One DC converter enabled and other 83040 can shared with this.
(9) Internal regulator output for DC converter controlled by control register. (2.5V to 4.6V, 8 level)
(10) Chip form (EM83040AH), 128 pin package (14mmx20mm EM83040AAQ), 160 pin package (EM83040ABQ)
(11) Bias : 1/5 for 32 common, 1/7 for 48 common, 1/9 for 80 common. Fixed by internal circuit.
(12) Internal RC clock about 250 KHz.
APPLICATION
(1) Data Bank
(2) LCD toy
(3) Education computer

As same as write mode , user has to sent address three times. And read data from RAM one by one which
address can be increased by internal counter. NOTE!! Be sure to make RAMR low pulse 2 µS (Tdv+data)
width and 2 µS (Tdd) high width at least.
(5) RAM mapping
RAM address is from 0 to address 2559
User fill “1” to LCD RAM , LCD driver will generate “light” waveform. Otherwise , it will generate a
“dark” waveform. The LCD RAM area is mapped to segment 1 to segment 80 from address 0 to address
19. And user can refer to fig.5 to get the idea of LCD ram mapping. The other RAM can use as general
RAM for data storage. And the RAM of address 2560 is a control register.
