ST7689 Détails du produit

INTRODUCTION
The ST7689 is a driver & controller LSI for 65K color graphic dot-matrix liquid crystal display systems. It generates 384 segments and 160 commons driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral Interface or 8-bit/16-bit parallel display data and stores in an on-chip display data RAM. It performs display data RAM read/write operation with no external operating clock to minimize power consumption. In addition, because it contains power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.

FEATURES
Driver Output Circuits
    ♦ 384 segment outputs / 160 common outputs
Applicable Duty Ratios
    ♦ Various partial display
    ♦ Partial window moving & data scrolling
Gray-Scale Display
    ♦ 4FRC & 31 PWM function circuit to display 64 gray-scale display
    ♦ Support 8 color mode (Idle mode)
On-chip Display Data RAM
    ♦ Capacity: 128 x 160 x 16 = 327,680 bits
Color support by Interface
    ♦ 256 color mode(RGB)=(332) mode
    ♦ 4k colors (RGB)=(444) mode
    ♦ 65K colors (RGB)=(565) mode
    ♦ 262K colors (RGB)=(666) mode (truncate)
Microprocessor Interface
    ♦ 8/16-bit parallel bi-directional interface with 6800-series or 8080-series
    ♦ 3-line (9-bits) , 4-line(8-bits) serial interface
On-chip Low Power Analog Circuit
    ♦ On-chip oscillator circuit and voltage regulator
    ♦ Voltage converter (x5, x6, x7, x8) with internal booster capacitors.
    ♦ Extremely few outsider components. (Required outsider components: 4 Capacitors)
    ♦ On-chip electronic contrast control function
    ♦ Voltage follower
        (LCD bias: 1/9, 1/10, 1/11, 1/12, 1/13, 1/14)
Operating Voltage Range
    ♦ Supply Digital Voltage -> VDDI (VDD) = 1.65~3.3V
    ♦ Supply Analog Voltage -> VDDA (VDD1, VDD2, VDD3, VDD4, VDD5) = 2.4~3.3V
    ♦ LCD driving voltage (VOP = V0 - VSS): Max: 18V
LCD Driving Voltage (PROM)
    ♦ Contrast Adjustment Value is stored in the built-in PROM (Programmable ROM) for better display quality
LCD Driving Setting Suggestion
    ♦ Vop=15~16V. Bias=1/9~1/11
Package Type
    ♦ Application for COG
