INTRODUCTION:
The MS3201 from Novalog is an IrDA 1.0 and 1.2 compli-
ant 115.2 kbps infrared transceiver module ideal for power
sensitive personal data transfer applications. Setting a new
industry benchmark the MS3201 will operate with the widest
available supply voltage range, 1.5V to 5.5V. The MS3201
is also compliant with Sharp ASK/DASK and Consumer IR
(TV Remote) specifications.
The MS3201 integrates an analog receiver, on-chip LED
driver, IR photodiode, IR LED transmitter, and voltage fil-
tering capacitor, Figure 1. Only one external current limiting
resistor is required. This external resistor should be selected
to optimize transmit distance and system power consump-
tion. An external metal shield is utilized on the MS3201 for
high EMI environments.
APPLICATIONS:
• Personal Digital Assistants (PDAs)
• Cellular Phones
• Pagers
• Financial Messaging (IrFM)
• Vending Machines
• Portable printers
• Digital Cameras
• Electronic Books
• Notebook computers
• MP3 players
• Storage peripherals
• Electronic identification
• Personal data transfer devices
The MS3201 is optically compatible with Novalogʼs Mini-
SIR family but utilizing an alternative pin out for existing or
new applications. The new 8 pin footprint adds a separate
pin for analog ground.
