Watch, calendar, calculator, etc.DescriptionSPL11A, a 8-bit LCD micro-controller, contains LCD-drivers, one-time programmable (OTP) ROM, SRAM, I/O, timer/counter, PLL, audio/remote control out, resistor to frequency converter (RFC) function in a single chip. The SPL11A is designed to drive LCD directly and perform efficient controller function as well as arithmetic function. With the on-chip crystal oscillator, real time clock can be easily achieved. For power savings, several power-down modes are controllable by software programming. The SPL11A is designed to be used in low-power electronic products such as remote controller, home appliance, calculator, and general LCD controller, etc.
