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 SPL09A 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.
