Z8FMC16100 Series Flash MCU
Product Specification
145
Infrared Encoder/Decoder
The Z8FMC16100 Series Flash MCU contains two fully-functional, high-performance
UART to Infrared Encoder/Decoders (endecs). Each infrared endec is integrated with an
on-chip UART to allow easy communication between the Z8FMC16100 Series Flash
MCU and IrDA Physical Layer Specification, 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.
Architecture

Operation
When the infrared endec is enabled, the transmit data from the associated on-chip UART
is encoded as digital signals in accordance with the IrDA standard and output to the infra-
red transceiver using the TXDpin. Likewise, data received from the infrared transceiver is
passed to the infrared endec using the RXDpin, decoded by the infrared endec, and passed
