ST7066U-Q

The ST7066U-Q is designed as one kind of dot matrix LCD controller / driver that can be used in configured to drive a dot-matrix liquid crystal display under the control of a 4- or 8-bit microprocessor. Also the character generator ROM of this device is extended to generate 208 5 x 8 dot character fonts and 32 5 x 11 dot character fonts for a total of 240 different character fonts.

Features of the ST7066U-Q are:(1)Wide range of instruction functions: Display clear, cursor home, display on/off, cursor on/off, display character blink, cursor shift, display shift; (2)Pin function compatibility with HD44780, KS0066 and SED1278; (3)Automatic reset circuit that initializes the controller/driver after power on; (4)Internal oscillator with external resistors; (5)Low power consumption; (6)QFP80 and Bare Chip available; (7)5 x 8 and 5 x 11 dot matrix possible; (8)Low power operation support: 2.7 to 5.5V; (9)Wide range of LCD driver power: 3.0 to 11V; (10)4-bit or 8-bit MPU interface enabled; (11)80 x 8-bit display RAM (80 characters max.).

The absolute maximum ratings of the ST7066U-Q can be summarized as:(1)Power Supply Voltage: -0.3 V to +7.0 V;(2)LCD Driver Voltage: -0.3 V to +13.0 V;(3)Input Voltage: -0.3 V to VCC+0.3 V;(4)Operating Temperature: -20 to +70 ;(5)Storage Temperature: -55 to +125 .
