General Description

The GPM6P1816A is a special chip for remote control with 256 bytes built-in SRAM and 16K bytes built-in OTP ROM. It includes three timers and up to 25 software selectable general I/Os. Additionally, it provides one frequency programmable and duty selectable Pulse Width Modulation (PWM) output for remote control. It operates over a wide voltage range of 2.0V - 3.6V@4/8MHz. It has a sleep mode for power saving mode which retains the contents of RAM, but stops the oscillator and causes all other chip functions to be inoperative. Sleep mode can be released by using external wakeup sources. This device is capable for many application fields such as low power watch and other LCD related products. Meanwhile, the built-in IR transfer module can make IR control and usage easily.
