Description

SPL081A, a special designed CMOS 8-bit microprocessor by Sunplus, 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 3.5A. Not only SPL081A is capable of displaying LCD, but it also can process complex instructions and functions as well. The development team has designed SPL081A to cover many application fields such as calculator, watch and other LCD related products required only one battery supply.
