APPLICATIONS: * Network Computer
IrDA Components Group
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 P enables PE to operate every protocol required for IrDA Control Infrared Wireless Communication * Optimized interface to SHARP IrDA Control Infrared Transceiver (SHARP P/N: GP2W2001YK) * Serial interface (Synchronous Serial Wire) is prepared for the interface between P and PE. * Low current consumption: ICC = 3 mA (at operation) * Supply Voltage: VDD = 2.7 V - 3.3 V
DESCRIPTION
SHARP IrDA Control Peripheral Engine will exchange the information with P 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 supported 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 P. 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.
