Zilog launches the Z382 high-performance datacom controller for ISDN, xDSL, and high-speed analog modems.CAMPBELL, Calif.--(BUSINESS WIRE)--March 24, 1997--Zilog, Inc. (NYSE NYSE See: New York Stock Exchange :ZLG) today unveiled its newest high-performance, cost-effective data communication processor, the Z382, targeted for high-speed ISDN ISDN in full Integrated Services Digital Network Digital telecommunications network that operates over standard copper telephone wires or other media. , HDSL See DSL. HDSL - High bit-rate Digital Subscriber Line , ADSL See DSL. ADSL - Asymmetric Digital Subscriber Line , and analog modems that support Internet access, video conferencing, remote LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. access, and computer telephony. "The Z382 utilizes the powerful 16/32-bit Z380(TM) CPU CPU in full central processing unit Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. and integrates peripherals such as ISA plug-and-play and PCMCIA (Personal Computer Memory Card International Association, San Jose, CA, www.pcmcia.org) An international standards body and trade association that was founded in 1989 to establish a standard for connecting peripherals to portable computers. PCMCIA created the PC Card. See PC Card. host interfaces; asynchronous Refers to events that are not synchronized, or coordinated, in time. The following are considered asynchronous operations. The interval between transmitting A and B is not the same as between B and C. The ability to initiate a transmission at either end. and HDLC (High-level Data Link Control) A data link protocol from ISO for point-to-point communications over serial links. Derived from IBM's SDLC protocol, HDLC has been the basis for numerous protocols including X.25, ISDN, T1, SS7, GSM, CDPD, PPP and others. serial controllers; counter/timers; DMA channels; and I/O ports," said Alex Goldberger, product manager for Zilog's high-performance serial communication processors. "This high level of integration translates into lower system costs by eliminating external interface devices, and reducing board space and power requirements." "The Z382 device complements our popular Z182 modem chip and strengthens Zilog's leadership position in embedded datacom processor applications," said Jim Magill, vice president of Zilog's data communication division. "Planned future members of the Z382 family include devices with on-chip 10/100 Mb Ethernet and USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. interfaces, and devices optimized for passive adapter applications, as well as higher speed versions of the products." Z380 CPU Architecture The 20 MHz Z380 architecture, featuring fast context switching via four register banks, allows the Z382 processor to rapidly respond to interrupts when switching among tasks. Additional improvements, which yield twice the performance of the Z180(TM) and as much as eight times that of the Z80(R), include two cycles per instruction, 16MB of linear address space, 16/32-bit instruction set, and dynamic bus sizing. Z80/180 customers can easily port their existing designs to the code-compatible Z380 code without discarding their investment in code development. DMA Channels and Serial Communications The Z382 processor's eight advanced DMA channels are dynamically assignable to client peripherals on the device. Each DMA channel has a pointer into a memory-resident list structure that contain the locations and lengths of data buffers. To support ADSL applications, the Z382 features three HDLC channels that can operate in HDLC, NRZI (Non-Return-to-Zero Inverted) A magnetic recording and data transmission method in which the polarity of the bit is reversed when a 1 bit is encountered. All subsequent 0s following the 1 are recorded at the same polarity. HDLC, and transparent modes, and intelligent DMA controllers to support up to 10 Mbps full duplex bandwidth. The HDLC inputs and outputs can be routed to and from the GCI/SCIT or external TDM (Time Division Multiplexing) A technology that transmits multiple signals simultaneously over a single transmission path. Each lower-speed signal is time sliced into one high-speed transmission. highway to interface with external transceivers, CODECS and other devices for ISDN applications. Development Support A full complement of Zilog and third-party support tools allow rapid hardware and software development and verification, speeding up time-to-market. Zilog's $599 Z382 evaluation kit contains an evaluation board, and a debug monitor program to download and debug executable code, and provides access to the device's registers and on-board memory. Application-specific circuits can be added through three expansion daughter-card sites to fully emulate the customer's end product. Orion Instrument's (800/721-7700) in-circuit-emulator provides real-time tracing capability, display, and editing of Z382 code. Software support in the form of an assembler, linker and C-Compiler is available from Production Languages Corporation (817/599-8365). Price and Availability The 5-volt Z382 is available in a 144-pin QFP and a 144-pin VQFP package and is priced in the $13 range in OEM high volumes. Zilog is an innovator in the development, design and manufacture of application specific standard products (ASSPs) for the consumer, intelligent peripherals, and data communications product controller markets. The company uses its Superintegration(TM) library of proprietary core and cell designs, which are optimized for particular market applications to meet the design, cost, and time-to-market requirements of its customers. Zilog has its headquarters in Campbell, California and had 1996 revenues of $298.4 million. It employs approximately 1,675 people worldwide and has 27 direct sales offices and more than 120 distributor and representative locations worldwide.
