Description
The TFDU4100, TFDS4500, and TFDT4500 are a family provides flexibility for a variety of applications and space
of low-power infrared transceiver modules compliant to constraints.
the IrDA 1.2 standard for serial infrared (SIR) data
communication, supporting IrDA speeds up to 115.2
kbit/s. Integrated within the transceiver modules are a The transceivers are capable of directly interfacing with
photo PIN diode, infrared emitter (IRED), and a a wide variety of I/O chips which perform the pulse-width
low-power analog control IC to provide a total front–end modulation/demodulation function, including TEMIC’s
solution in a single package. TEMIC’s SIR transceivers TOIM3000 and TOIM3232.
At a minimum, a
are available in three package options, including our current-limiting resistor in series with the infrared emitter
BabyFace package (TFDU4100), the smallest SIR and a Vcc bypass capacitor are the only external
transceiver available on the market. This wide selection components required to implement a complete solution.
