1. The HL6024(LQFP44,compatible with PCF8566) is a peripheral device which interfaces to almost any Liquid Crystal Display (LCD) having low multiplex rates. It generates the drive signals for any static or multiplexed LCD containing up to four backplanes and up to 24 segments and can easily be cascaded for larger LCD applications. The HL6024 is compatible with most microprocessors/microcontrollers and communicates via a two-line bidirectional I2C-bus. Communication overheads are minimized by a display RAM with auto-incremented addressing, by hardware subaddressing and by display memory switching (static and duplex drive modes).
2. HL6024：是一款通用的LCD驱动芯片，可驱动96段或12个8段数字字符，6个15段字母字符。有4条控制指令，对HL6024可进行多种状态控制。
电源范围：2.5V～6.0V，工作于低功耗状态时，5V动态电流为30uA，3V最小动态电流为16uA。可作多芯片级联，级联总数可达16片，故最大可驱动1536段。此型号兼容飞利浦PCF8566,DF3566。此产品主要用于单相电能表上，广泛应用于复费率电度表、各种影碟机，功放机，VCD，DVD，空调，消毒柜，价格和同类产品相比有绝对优势

3. The HL9576(LQFP64,compatible with PCF8576) is a peripheral device which interfaces to almost any Liquid Crystal Display (LCD) with low multiplex rates. It generates the drive signals for any static or multiplexed LCD containing up to four backplanes and up to 40 segments and can easily be cascaded for larger LCD applications. The HL9576 is compatible with most microprocessors/microcontrollers and communicates via a two-line bidirectional I2C-bus. Communication overheads are minimized by a display RAM with auto-incremented addressing, by hardware subaddressing and by display memory switching (static and duplex drive modes).
