Infrared Encoder/Decoder
Overview
The 64K Series products contain two fully-functional, high-performance UART to Infra-
red Encoder/Decoders (Endecs). Each Infrared Endec is integrated with an on-chip UART
to allow easy communication between the 64K Series and IrDA Physical Layer Specifica-
tion, Version 1.3-compliant infrared transceivers. Infrared communication provides
secure, reliable, low-cost, point-to-point communication between PCs, PDAs, cell phones,
printers and other infrared enabled devices.
