Products - GPM6P1916A

General Description

GPM6P1916A is designed for LCD remote control application with 256 bytes built-in SRAM and 16K bytes built-in OTP ROM.  It includes three timers and up to 41 software selectable general I/Os.  Additionally, it provides two frequency-programmable and duty- selectable Pulse Width Modulation (PWM) output, one for remote control, the other for user’s function application. It operates over a wide voltage range of VLVR - 3.6V and has a sleep mode for power saving mode, which retains the contents of RAM, but stops the oscillator to make all other chip functions to be inoperative.  The sleep mode can be released by using internal time based and external wakeup sources. This chip is applicable in 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.
