Description

The ST7066 dot-matrix liquid crystal display controller and driver LSI displays alphanumeric, Japanese kana characters, and symbols. It can be configured to drive a dot-matrix liquid crystal display under the control of a 4- or 8-bit microprocessor.

Since all the functions such as display RAM, character generator, and liquid crystal driver, required for driving a dot-matrix liquid crystal display are internally provided on one chip, a minimal system can be interfaced with this controller/driver.

Features

● 5 x 8 and 5 x 11 dot matrix possible

● Low power operation support:

-- 2.7 to 5.5V

● Wide range of LCD driver power

-- 3.0 to 11V

● Correspond to high speed MPU bus interface

-- 2 MHz (when VCC = 5V)

● 4-bit or 8-bit MPU interface enabled

● 80 x 8-bit display RAM (80 characters max.)

● 9,920-bit character generator ROM for a total of

240 character fonts

-- 208 character fonts (5 x 8 dot)

-- 32 character fonts (5 x 11 dot)

● 64 x 8-bit character generator RAM

-- 8 character fonts (5 x 8 dot)

-- 4 character fonts (5 x 11 dot)

● 16-common x 40-segment liquid crystal display

driver

● Programmable duty cycles

-- 1/8 for one line of 5 x 8 dots with cursor

-- 1/11 for one line of 5 x 11 dots & cursor

-- 1/16 for two lines of 5 x 8 dots & cursor

● Wide range of instruction functions:

Display clear, cursor home, display on/off,

cursor on/off, display character blink, cursor

shift, display shift

● Pin function compatibility with HD44780,

KS0066 and SED1278
