HT1621G

The HT1621G is one member of the HT1621 family which is designed as one kind of 128 pattern (324), memory mapping, and multi-function LCD driver.It suitable for multiple LCD applications including LCD modules and display subsystems because of the S/W configuration feature.

Features of the HT1621G are:(1)LCD voltage:3.6V to 4.9V;(2)logic operating voltage: 2.4V to 3.3V;(3)low operating current <3 A at 3V;(4)external 32.768 kHz crystal oscillator;(5)selection of 1/2 or 1/3 bias, and selection of 1/2 or 1/3 or 1/4 duty LCD applications;(6)internal time base frequency sources;(7)two selectable buzzer frequencies (2kHz/4kHz);(8)built-in capacitor type bias charge pump;(9)time base or WDT overflow output;(10)8 kinds of time base/WDT clock source;(11)32x4 LCD driver;(12)built-in 32x4-bit display RAM;(13)3-wire serial interface;(14)internal LCD driving frequency source;(15)software configuration feature;(16)R/W address auto increment;(17)data mode and command mode instructions;(18)three data accessing modes.

The absolute maximum ratings of the HT1621G can be summarized as:(1)supply voltage:-0.3V to 3.6V;(2)input voltage:VSS-0.3V to VDD+0.3V;(3)storage temperature:-50 to 125;(4)operating temperature:-25 to 75.If you want to know more information such as the electrical characteristics about the HT1621G,please download the datasheet in www.seekic.com or www.chinaicmart.com .
