GPL081A5中文资料Low power 8 bit LCD controller w/ VLCD Regulator, Max 3072dots, up to 160KB ROM Calculator, Time-Piece数据手册Generalplus规格书

描述 Description

GPL081A5, a special designed CMOS 8-bit microprocessor by Generalplus, combines RAM, ROM, I/Os, an interrupt controller, and an automatic display controller/driver in a small package.  One of its extraordinary features is the capability of operating in low voltage range, from 1.2V through 1.7V.  The Power Down Mode, consuming less than 3.5uA, keeps LCD displaying while CPU is in standby mode.  Not only GPL081A5 is capable of displaying LCD, but it also can process complex instructions and functions as well.  The development team has designed GPL081A5 to cover many application fields such as calculator, watch, and other LCD relevant products powered by one battery.
