IDT Extends RISController Family With Introduction
of New High-Performance 64-Bit Microprocessors
New RISController Microprocessors are Pin- and Software-Compatible with Existing IDT
Embedded Processors; Widen Support for Windows CE
SANTA CLARA, Calif.--(BUSINESS WIRE)--Sept. 21, 1998-- IDT (Nasdaq:IDTI - news), a leading manufacturer of
RISC microprocessors, today introduced two new 64-bit RISController(tm) microprocessors, the IDT RC64474(tm) and
IDT RC64475(tm).
The RC64474/475 are superset pin-compatible with IDT's existing 64-bit RC4640(tm) and RC4650(tm) processors. This
enables customers to upgrade their current systems and take advantage of the increased performance and added features of
the new processors without having to redesign system hardware.
New features provided by the RC64474/475 include 3.3-volt operation with tolerance for 5-volt I/O, a JTAG interface, which
enables boundary scan for simplified board production and board-level testing, and an enhanced write mode to simplify
support of synchronous DRAMs.
High performance, large internal and external data bandwidth, and rapid interrupt response make the RC64474/475 ideal
solutions for communications applications such as Layer 3 switches and routers, xDSL DSLAMs, firewall systems and WAN
access multiplexers. Additionally, the new processors are fully compliant with the requirements of the Microsoft(R)
Windows(R) CE operating system as well as other key embedded RTOSs.
Support for this industry-standard operating system, combined with high performance, also make the RC64474/475 an
excellent fit for emerging consumer applications such as network computers, digital set-top Web browsers and digital
entertainment centers.
''We're building on the success we've had with our family of pin-compatible 32-bit RISC processors to now provide a wider
range of 64-bit solutions to meet the varied price/performance requirements of our customers,'' said Nick Kucharewski, vice
president of IDT's microprocessor division.
''The high level of compatibility for all our processors preserves our customers' investments in software, development tools
and design time, enabling faster time-to-market and providing migration paths to higher-performance products or more
cost-effective solutions.''
High Real-Time Performance and Large Bandwidth
Both the RC64474 and RC64475 are based on the RISCore4000(tm) architecture and implement the MIPS III
instruction-set architecture. At the core of the processors is a 64-bit RISC CPU with a streamlined, high-speed 5-stage scalar
pipeline that minimizes branch and load delays, delivering 330-Dhrystone MIPS at 250 MHz.
Both processors provide two-way, set-associative caches (16-Kbyte instruction, 16-Kbyte data) with cache locking, which
enables locking time critical routines and data structures in the caches, making them always available to the execution core.
Other devices in this RISCore4000 family include the RC4700(tm), RC4640 and the RC4650.
The RC64474 uses a 32-bit external system interface bus, providing designers with the ideal combination of 64-bit processing
power and low-cost, 32-bit memory, thereby reducing overall system cost. The RC64475 utilizes the full 64-bit external
system interface bus, providing more than 1-GBps bus bandwidth and 4-GBps overall system bandwidth.
''We look forward to taking advantage of the increased performance and added bandwidth of the new IDT RC64474
processor for our next-generation broadband access multiplexer,'' said Mitri Halabi, director of engineering for 3Com
Corporation's Broadband Access Division. ''The breadth of IDT's RISC offerings and its extensive suite of development tools
and software support allows us to bring multiple systems to market quickly at different price points, without having to reinvest
in our development efforts.''
For board- and system-level design support, the new RC64474/475 processors are part of the Advantage IDT(tm) program,
comprised of more than 120 leading tools vendors and greater than 150 development tools products. The majority of available
tools in the program for the RC4700 and RC4640/50 processors will support the RC64474/475 without modifications,
including compilers, emulators, logic analyzer interfaces, system logic chips, RTOS, application software and reference
designs.
A variety of peripheral support chips is also available to enable RC64474/475-based systems to achieve rapid time-to-market
and application-specific functionality.
World-Class RISController Series of Embedded Microprocessors
The RC64474 and RC64475 microprocessors are the latest addition to IDT's widely used 32/64-bit RISController series of
embedded microprocessors, based on the MIPS instruction set. The new microprocessors are positioned between the
company's RC4640/50 64-bit processors and its high-end RC5000(tm) microprocessor.
Offering a wide range of software-compatible, price/performance choices, IDT has optimized the designs of its
high-performance microprocessors for use in an assortment of embedded communications applications, including
internetworking, multimedia, datacom and telecom products.
Also, superior price/performance, innovative architecture, low-power consumption, small form factor and comprehensive tools
support have made the IDT RISController series the standard for a number of digital consumer products for leading
companies.
Pricing and Availability
The RC64474 is offered in a 128-pin QFP package. The 180-MHz version is priced at $27 each, the 200-MHz version at
$38 each, and the 250-MHz version will sell for $59 each, all in 10,000-piece quantities. The RC64475 is offered in a
208-pin QFP package. The 180-MHz version is priced at $38 each, the 200-MHz at $50 each, and the 250-MHz version
will sell for $68 each, all in 10,000-piece quantities.
The devices are currently sampling, with production in late Q4CY98. Industrial temperature versions of the devices will be
available in Q1CY99.
