SC1621 Datasheet | SilvanChip

Description LCD 驱动电路 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 mand to reduce power consumption. SC1621Features z z z z z z Operating voltage: 2.4V~5.2V Built-in 256k Hz 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 mand mode instructions R/W address auto increment Three data accessing modes Power down mand reduces power Consumption SC1621Pad Assignment IC SIZE:2.20mm X 2.15mm The ic cubstrate should be connecte to VDD in PCB layout artwork 森川电子科技有限公司 TEL: 0755-88291843 88304213 E-mail: jja@sc-tech.cn ADD: 深圳市福田滨河路海滨广场福长阁 16 楼 Http:// .sc-tech.cn Free Datasheet http://../ SC1621 Pad Coordinates LCD 驱动电路 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 mand 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 mand transmission between the host controller and the SC1621 are all enabled. READ clock input with pull-high resistor.

The clocked out data will appear on the DATA line. The host controller can use the next rising edge to latch the clocked out data. WRITE clock input with pull-high resistor. Data on the DATA line are latched into the SC1621 on the rising edge of the WR-signal....
