PRODUCT INFORMATION
®
LZ8519X IrDA
Control Peripheral
Engine (PE)
FEATURES
• All-in-One Embedded Communication Controller (Encoder/
Decoder, IrDA, IrDA Control MAC Layer, HID LLC Layer)
• Simple Command given by an ordinary µP enables PE to
operate every protocol required for IrDA Control Infrared
Wireless Communication
• Optimized interface to SHARP IrDA Control Infrared Trans-
ceiver (SHARP P/N: GP2W2001YK)
• Serial interface (Synchronous Serial Wire) is prepared for the
interface between µP and PE.
• Low current consumption: ICC = 3 mA (at operation)
• Supply Voltage: VDD = 2.7 V - 3.3 V
APPLICATIONS:

DESCRIPTION
SHARP IrDA Control Peripheral Engine will exchange the infor-
mation with µP through this serial interface (SS-Wire). Only two
attributes, ‘Command’ and ‘Message’, a simple software will be
used for information transaction. Other protocol stacks are sup-
ported by PE and users can simply minimize design effort and time.
The SHARP IrDA Control Peripheral Engine (PE) is an
embedded Communication controller, designed to fully support
IrDA Control MAC Layer and HID LLC Layer services. It has an
optimized interface to SHARP IrDA Control transceiver, and the
Serial Interface (Synchronous Serial Wire) for µP.
Since IrDA Control MAC layer and HID LLC layer protocol stacks
are already built-into PE, one can easily implement IrDA Control
Peripherals with SHARP IrDA Control transceiver and PE.
