Data Sheet
Description
The ASDL-3212 is a new generation ultra small low cost
infrared transceiver module which is compliance to IrDA
Physical Layers speci cations version 1.4 low power
from 9.6Kbits/s to 1.152Mbit/s (MIR) with extended link
distance. It is IEC825-Class 1 eye safe and designed for
very low power consumption which is ideal for battery
operated handheld devices. ASDL-3212 features lower
pin count through integrated input-output function for
interfacing with low voltage 1.5V
