Preliminary

SPL09A

5KB LCD CONTROLLER/DRIVER

GENERAL DESCRIPTION

The SPL09A is a CMOS 8-bit single chip microprocessor, which contains RAM, ROM, I/Os, interrupt/wakeup

controller, timer and automatic display controller/driver for LCD. This chip is designed not only low power

consumption but also provides standby mode controlled by software for power saving. It is very suitable for LCD

hand-held products.
