LC7463M

The LC7463M is a 32-key infrared remote control transmitter IC that incorporates all key-scanning, oscillator and timing functions on-chip, resulting in a very low external component oount. The LC7463M generates 35 function codes using the 32 function keys; The output data format comprises the mask-programmed custom code, the parity field, the mask-programmed system code, the product code, the function code and the data check code. The LC7463M operates from a 2.0 to 3.6 supply and is available in 20-pin MFPs.

The features of LC7463M can be summarized as (1)low external component count ; (2)32 function keys ; (3)35 function codes; (4)Mask-programmable custom and system codes so ; (5)64 product codes ; (6)output conforms to japan's association for electric home appliances recommended standards for infrared remote controls. ; (7)on-chip input pull-down resistors ; (8)2.0 to 3.6 supply ; (9)20-pin MFP.

The absolute maximum ratings of LC7463M are (1)supply voltage range VCC: VSS-0.3 to 5.5V; (2)input voltage range Vt: VSS-0.3 to VDD+0.3V; (3)output voltage range VO: VSS-0.3 to VDD+0.3V; (4)output current ID: -35mA; (5)power dissipation PD: 150mW; (6)operating temperature range Topr: -40 to 85°C; (7)storage temperature range Tstg: -50 to 125°C.
