General Description

The GPM6P1129B is a special chip for remote control with 512 bytes built-in SRAM and 128K bytes built-in OTP ROM. It includes three Timers and up to 17 software selectable general I/Os. Additionally, it provides one frequency programmable and duty selectable (TMASET=0) or programmable (TMASET=1) Pulse Width Modulation (PWM) output for remote control. Furthermore, it provides built-in capture mode timer for input signal frequency detecting by infrared learning function. It operates over a wide voltage range of LVR ~ 3.6V. It features two SLEEP modes: normal sleep and key scan sleep. Both sleep modes keep SRAM contents but stop the oscillator and resulting all other chip functions to be inoperative for power saving. In normal sleep mode, it can be released by using external key change. In the key-scan sleep mode, IO will be scanned continually and be released at key press. Especially, it has a very accuracy internal OSC, which matches the specification of 4MHz ± 1.5% (typical) under LVR ~3.6V and can be used for most applications. Meanwhile, the built-in IR transfer module makes IR control and use easily.
