SC1621

SC1621 SC1621General Description LCD The SC1621 is a 128 dots (32x4), memory mapping, and multi-function LCD driver. The S/W con-figuration feature of the SC1621 makes it suitable for multiple LCD applications including LCD modules and display subsystems. Only three or four lines are required for the interface between the host controller and the SC1621. The SC1621 contains a power down command to reduce power consumption. SC1621Features z z z z z z Operating voltage: 2.4V~5.2V Built-in 256kHz RC oscillator 8 kinds of time base/WDT clock sources 32x4 LCD driver 3-wire serial interface Internal LCD driving frequency source z z z z z Software configuration feature Data mode and command mode instructions R/W address auto increment Three data accessing modes Power down command reduces power Consumption SC1621Pad Assignment IC SIZE:2.20mm X 2.15mm The ic cubstrate should be connecte to VDD in PCB layout artwork TEL: 0755-88291843 88304213 E-mail: jja@sc-tech.cn ADD: 16 Http:// www.sc-tech.cn Free Datasheet http://www.datasheet4u.com/ SC1621 SC1621 Pad Coordinates LCD SC1621 Pad Descriptions Pad No. Pad Name I/O Description Chip selection input with pull-high resistor. When the CS- is logic high, the data and command read from or written to the SC1621 are disabled. The serial interface circuit is also reset. But if CS- is at logic low level and is input to the CS- pad, the data and command transmission between the host controller and the SC1621 are all enabled. READ cl...
