GPM6P1015A数据手册Generalplus中文资料规格书

描述 Description

GPM6P1015A is chip especially designed for remote control featuring 256 bytes built-in SRAM and 16K bytes built-in OTP ROM.  It includes three Timers and up to 13 software selectable general I/Os.  Additionally, it provides one frequency programmable and duty selectable Pulse Width Modulation (PWM) output for remote control.  And it provides built-in capture mode timer for input signal frequency detecting by infrared learning function.  It operates over a wide voltage range of 2.0V - 3.6V@4MHz.  It has a SLEEP mode for power savings which retains RAM's contents, but stops the oscillator and causes all other functions to be inoperative.  The SLEEP mode can be released by using external wakeup sources.  In addition, it provides a FREEZE mode to save power and to lock keyboard when power-supply voltage is detected lower than VLVR.  In FREEZE mode, CPU and peripheral are stopped, and all I/Os maintain floating with input function disabled.  The FREEZE mode releases when power-supply voltage recover from VLVR.  Especially, it has a very accuracy internal OSC, which matches the specification ±1.5%(typ) @ 2.0V~3.6V  Meanwhile, the built-in IR transfer module can make IR control and utilization easily.
