LC7465 Datasheet PDF - SANYO -> Panasonic

Overview
The LC7465M is a 64-key infrared remote controller transmitter IC that incorporates key-scanning, oscillator and timing circuits on-chip, resulting in a very low external component count.
The LC7465M generates 256 function codes using the 64 function keys. The output data format comprises the maskprogrammed custom code, the parity field, the mask-programmed system code, the product code, the function code and the data check code.
The LC7465M operates from a 2.0 to 3.6 V supply and is available in 30-pin MFPs.
