Z8FMC16100 Series Flash MCU

Product Specification

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

Figure 19 illustrates the architecture of the infrared endec.

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 TXD pin. Likewise, data received from the infrared transceiver is

passed to the infrared endec using the RXD pin, decoded by the infrared endec, and passed
