1 General Description

The EM62100 is a 65 Common 132 Segment dot matrix liquid crystal display (LCD)

driver LSI. It can be connected directly to a microprocessor bus, and selected as an

8-bit parallel or serial data input interface. The EM62100 IC device contains 65x132

bits of display data RAM and there is a one-to-one correspondence between the LCD

panel pixels and the internal RAM bits.

The EM62100 chip can drive a 65x132 dot display, so that a single chip of EM62100

can drive a maximum of 65x132 or 55x132 or 49x132 or 33x132 dots display with the

pad option (DUTY1, DUTY0). Moreover, the capacity of the display can be extended

by master/slave structures between chips. The chips can minimize power consumption

since no external operating clock is necessary for the RAM read/write operation.

Furthermore, each chip has a built-in low-power LCD driver power supply, on-chip

resistors for LCD driver power voltage adjustment and a built-in display clock CR

oscillator circuit, hence, the EM62100 chip can be used to create the lowest power

display system with the fewest components for high-performance portable devices.

2 Features

Direct display of RAM data through the display data RAM. RAM bit data:

“0”: non-illuminated “1”: illuminated (at normal display)

RAM capacity of 65*132 = 8,580 bits

Display driver circuits: 65 common output and 132 segment outputs

High-speed 8-bit MPU interface (80-series and 68-series) / Serial interfaces are

supported.

Multiple command functions: display data Read/Write, display ON/OFF, status

read, Normal/Reverse display mode, page address set, display start line set,

column address set, entire display ON/OFF, LCD bias set, electronic volume,

read-modify-write, segment driver direction select, power saving, static indicator,

common output status select, V0 voltage regulation internal resistor ratio set.

Other command functions: Partial display, partial start line set, N-Line inversion.

Built-in Static drive circuit for indicators

Built-in low-power LCD power supply circuit: Booster circuit (with Boost ratios of

two/three/four/five times, where the step-up voltage reference power supply can

be input externally), High-accuracy voltage adjustment circuit (external input),

built-in V0 voltage regulator resistors, built-in V1 to V4 voltage divider resistors,

built-in electronic volume function, and voltage follower.
