Introduction

Vx901M is a highly integrated, low-power learning-type RF decoder IC. The Vx901M integrates decoding, squelch, data error correction, learning, and code pairing functions, and features 4-channel interlocked, momentary, latched, and multiple combination output modes. It is compatible with various fixed-code encoder ICs such as EV1527, PT2262, PT2260, PT2240, SC2260, etc., and supports a code width range of 100us~2000us. The built-in high-capacity EEPROM supports learning of up to 80 remote controllers. The Vx901M comes in a SOP8 package with an operating voltage range of 2.2~5.0V and a normal operating current of 0.5mA. Only one button on a remote controller needs to be learned to automatically assign 4 output channels in one-to-one correspondence with 4 buttons.
