Preliminary
Overview
The LC7464M is a 64-key infrared remote control transmitter IC that incorporates all key-scanning, oscillator and
timing function on-chip, resulting in a very low external
component count.
The LC7464M generates 71 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 LC7464M operates from a 2.0 to 3.6 V supply and is
available in 24-pin MFPs.
Features
• Low external component count.
• 64 function keys.
• 71 function codes.
• Mask-programmable custom and system codes.
• 64 product codes.
• Output conforms to Japan’s Association for Electric Home
Appliances recommended standards for infrared remote
controls.
• On-chip input pull-down resistors.
• 2.0 to 3.6 V supply.
• 24-pin MFP.
