GPL081A1中文资料Low Power 160 Dots LCD Controller with 7KB Rom数据手册Generalplus规格书

描述 Description

GPL081A1, a special designed CMOS 8-bit microprocessor by Generalplus, offers the best cost/performance ratio in the industry. It 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 ~ 1.7V. The Power Down Mode keeps LCD being displayed when CPU is in standby mode, but consumes only less than 3.5μA. Not only GPL081A1 is capable of displaying LCD, but it also can process complex instructions and functions as well. The development team has designed GPL081A1 to cover many application fields such as calculator, watch and other LCD related products required only one battery supply.
