8bit MCU takes 15 Internet protocols onboard
ZiLog has begun shipments of its eZ80 Webserver (eZ80190), enabling easy, cost-effective, direct connections to networks and the Internet.
Frugal IrDA transceivers can stay on all the time
ZiLog has released the first devices in its new UltraSlim IrDA transceiver family designed to bring always-on, always power-efficient infra-red connectivity to compact portable systems.
"Our eZ80 Webserver-i allows engineers to build a scaleable system for much less than the cost of our competitors.
We deliver 16Mbyte of memory address space, 50MHz performance, Z80 and Z180 compatibility, a full Internet protocol stack, and an Ethernet reference design, all at a $5.72 price point (1000 units).
That's massive performance at a great price", said Norman Sheridan, Senior Vice President of System Development for Zilog.

MCUs raise the bar for 8bit systems
Zilog's new high-performance eZ80Acclaim! 8bit microcontroller family features up to 256Kbyte of reprogrammable Flash memory, Ethernet MAC and TCP/IP protocols and a complete design kit.
MCUs put more Flash in smaller packages
The latest additions to the Z8 Encore! family of Flash microcontrollers feature 4 or 8Kbyte of high-speed Flash memory housed in 20- and 28-pin SOIC packages.
Zilog's comprehensive eZ80 Webserver-i development kit leverages the existing Internet infrastructure to create a powerful tool that allows engineers without Internet expertise to web-enable their applications in as little as 48 hours.
In addition, Zilog announced two new development tools with an easy-to-understand interface that reduces an engineer's learning curve.
The ability to learn faster allows engineers to reduce total system development time and enhance time-to-market.
The eZ80L92 is a power efficient, optimised pipeline architecture microprocessor operating up to 50MHz.
The eZ80L92 includes an IrDA-compatible infra-red encoder/decoder; power management features such as sleep/halt modes and peripheral power down controls; general purpose port pins; serial ports; SPI; and I2C port.
The eZ80 architecture enables the eZ80 family of processors to function 10 to 16 times faster than the widely used Z80 processor while occupying only one-quarter of the space and consuming less than half of the power.
Unlike most 8bit microprocessors that can only address 64Kbyte, the eZ80 microprocessor addresses 16Mbyte without a memory management unit.
It also performs 24bit arithmetic for higher throughput.
The eZ80 microprocessor features 8bit instructions for code efficiency and 16bit registers for high application performance.
The "enhanced" mode extends all registers to 24bit.
To help facilitate embedded Internet applications, special instructions help to bulk-move TCP/IP packet data as it is being processed.
A 16Mbyte linear addressing range is one of the largest addressing ranges available for an 8bit processor.
The eZ80 Webserver-i E-Net module is a compact, high-performance Ethernet module specially designed for rapid development and deployment of embedded systems requiring control and Internet/Intranet connectivity.
Combined with a 10Mbit/s 802.3 Ethernet controller, memories, and Zilog's industry-leading IrDA transceiver, this module is ideal for wireless IrDA connectivity, industrial control, communication, security, automation, and embedded networking applications.
For rapid development, this module can interface to the Zilog development platform, which provides a complete user debug environment with power, breadboard area, and serial connectors such as RS232 and JTAG.
For deployment, this compact module interfaces to a user system via its system interface connectors.
An RJ-45 Ethernet connector is provided on the module.
The Embedded Webserver software suite is a no-compromise suite with all the subprotocols and options required to function on a busy network.
On-chip features and functionality allow the eZ80 microprocessor to act as a full-featured embedded Webserver while maintaining complete, real-time control over an embedded system.
The software suite implements full-featured Internet protocol stacks, including TCP/IP, the standard of Internet communication, and HTTP to enable users' software to support HTML.
The suite delivers 16 Internet protocols: TCP, UDP, IP, ARP, RARP, ICMP, IGMP, PPP, SMTP, HTTP, TELNET, DNS, TFTP, SNMP, DHCP/BOOTP and TIMEP.
The suite enables users to remotely manage, control, diagnose and reconfigure products from any point of Internet access.
Unlike other 8bit devices, the software suite adheres to the standards defined by groups such as the Internet Engineering Task Force (IETF) and the World Wide Web Consortium.
The solution also includes Ethernet and serial device drivers and implements the most relevant and latest approved Request for Comments (RFCs) from the IETF.
The latest Zilog Developer Studio or ZDS II is a complete integrated development environment highly tuned for embedded applications, and focused on simplifying the complexities of the embedded work environment.
This introduction underscores Zilog's commitment to high-quality tools that lead to lower system design cost and shorter time-to-market.
A second tool, ZPAK II represents an evolutionary step forward in in-circuit emulation.
A key component in Zilog's tools offering, ZPAK II is a high-speed emulation system that allows engineers to debug code, on actual hardware, while sitting at their desk, in a remote lab, or from anywhere else in the world over the Internet.
This ability gives engineers the flexibility to choose their work environment, which is needed to meet today's demanding schedules without sacrificing quality or usability.
Its small size, low cost, high-speed, LAN and Internet connectivity make it unique in the marketplace.
Zilog's royalty-free TCP/IP Internet software suite is an integrated, pre-emptive multitasking OS and TCP/IP protocol stack that meets all of the relevant Request for Comment (RFCs).
It is optimised for embedded systems and is implemented as an extension to the Zilog C compiler's runtime library.
A set of well-documented OS and network service APIs allow system developers to quickly take advantage of the Zilog TCP/IP software suite, while remaining focused on the main application.
Final binary output from the compiler/linker is the complete user application with networking capabilities across the Internet or any Intranet.
The eZ80 Webserver-i Ethernet module is available as a stand-alone device and in volume quantities for customer production runs.
To help expedite customer evaluation and product development, a low-cost development kit is also available.
