ZirDA™ Protocol Stack
IrDA Software for eZ80Acclaim!™ MCUs
OVERVIEW
•
Provides a total infrared data transfer solution
• S
upports the eZ80Acclaim!™ family of
microprocessor and microcontroller devices and
ZiLOG's ZHX-series IrDA transceivers
•
Configurable, Scalable, and Modular in Design
ZiLOG's ZirDA™ is a highly optimized IrDA-compliant
protocol stack. It is a layered set of embedded
protocols that provides a total data transfer solution
over the infrared medium. Designed for use with
ZiLOG's award-winning eZ80Acclaim!™
microcontrollers and ZHX-series IrDA transceivers,
ZirDA™ supports all mandatory IrDA protocols and
provides easy-to-use APIs. ZirDA™ targets portable
office equipment applications, wireless serial adapters,
cell phones, PDAs, pagers, digital cameras, and
emerging markets such as fixed IrDA online access
beacons.
Scalable and modular in design, the ZirDA™ protocol
stack provides an extensive feature set and easy-to-use
APIs. It helps you get your product to market faster and
increases reliability because it provides modules that
handle low-level IrDA functions. Based on ZiLOG's
Real-Time Kernel RZK, ZirDA™ is meant to be
integrated with the main user application software
required to complete the wireless IrDA communication
system.
ZirDA™ is compatible with ZDS II, ZiLOG's Integrated
Development Environment that provides compiling,
debugging, and project-building tools for quick and
efficient embedded application development. A sample
IrDA monitor application is included to demonstrate
ZirDA™ features.

ZirDA™ Features
Complete IrDA Stack Functionality
ZirDA™ includes the SIR framer, IrLAP, IrLMP, IAS, and
TinyTP protocol implementations. Optional add-in
services include IrCOMM (3-wire RAW, IrLPT) and
IrOBEX.
Rapid Application Development
Uses built-in functions to handle low-level IrDA
functions such as IAS connection establishment.
Emulate Serial Ports Through IrCOMM
Supports legacy applications that require serial ports
over IrDA without modification using ZirDA™'s
extensive APIs.
Information Access Service
Supports all mandatory IAS services. Application
developers can set IAS class and attribute name sizes
in a configuration file to reduce RAM usage.
High-Level Flow Control Using TinyTP
Supports all the mandatory services of TTP. Per-
channel flow control keeps data moving smoothly.
Supports SAR (Segmentation and Reassembly).
Multiple Logical Channels on a Single Physical Link
Using IrLMP
ZirDA™'s IrLMP allows services of one device to
communicate with identical services in a peer device
without interference from other services using the
same IrLAP connection. Supports Exclusive Access
Mode. The number of supported LSAP connections is
configurable to meet RAM requirements.
Reliable Connection Through IrLAP
ZirDA™'s IrLAP provides a point-to-point reliable
connection that supports services such as Discovery,
Address Conflict Resolution, connection
establishment, data transfer, and flow control.
Application developers set QOS parameters by calling
a simple API.
Compile-Time Configurable
All options are compile-time configurable.
Supports Security and Power Savings
Provides APIs that allow all of the managed
peripherals to operate in power-save mode when not
in use.
Built on ZiLOG's ZDS II Integrated Development
Environment
ZDS II provides industry-leading tools that speed
development and reduce time to market. ZDS II
includes a full-featured ANSI C-compiler and
debugger, and is a part of all eZ80Acclaim!™
development kits.
With ZirDA™ protocol software, ZiLOG's
eZ80Acclaim!™ Flash MCUs, and ZHX-series IrDA
transceivers, ZiLOG provides the embedded industry's
first complete Flash-based solution for wireless IrDA
connectivity, thus maintaining upgradeability and
reducing development cycle time and cost of
ownership.
