Motorola
Shifting Chip Production to Foundry Partners
As part
of its most recent reorganization, Motorola's Semiconductor
Products Sector (SPS) has collapsed its product organization
and profoundly altered its chip-making plans. Semiconductor
operations deflated from 23 product groups into just four.
Some were reorganized, some were sold, some were eliminated.
Among the fallen were optoelectronics, DRAMs, chemical sensors,
gate arrays, FPGAs, and power electronics.
The four
surviving groups are now organized around transportation,
wireless, networking, and imaging/entertainment. (Discrete
components are handled through a fifth independent group.)
The transportation group oversees MCore; StarCore DSPs are
part of the wireless group; imaging owns 68K/ColdFire; and
PowerPC is the responsibility of the networking group.
Under
the new plan, called Standardize & Simplify, Motorola will
consolidate its fabrication processes and rationalize its
design rules. It will sell off, rather than refit, older fabs
that do not match its current 8-inch production processes.
Motorola has already closed plants in California, Texas, Arizona,
North Carolina, the Philippines, and elsewhere. The plan parallels
Intel's famous Copy Exact policy, where semiconductor plants
are interchangeable.
Standardize
& Simplify extends beyond Motorola's own fab equipment. By
next year, 30% of production is slated to go to external foundries.
Over the next three years, Motorola will shift half of its
production to foundries. This is a huge strategic redirection
for a company that currently farms out only 6% of its production.
Regarding
the much-ballyhooed copper process, Motorola vowed to ship
more chips using copper interconnect in 1999 than any other
vendor, including IBM.
Motorola
will not build any new fabs "for some time," according to
company executives, and the next one it does build will run
huge 300- millimeter wafers. It's likely such a plant will
be a joint venture with AMD or Siemens (both of which have
process-level agreements with Motorola), possibly located
in Dresden, Germany.
To reconcile
the seemingly conflicting goals of standardizing its semiconductor
process and pushing work out to foundries, Motorola will "engage
in partnerships" with foundries around the world, outfitting
them for Motorola-compatible processes. Such Motorola-assisted
foundries are hoped to be interchangeable with Motorola's
own plants. Chips made at one location will be manufacturable
at any other.
This
scheme represents a Faustian bargain for the foundries. They
must accept and adapt to Motorola's processes. On the other
hand, they will (collectively, at least) take 50% of Motorola's
mammoth production.
IDT
Debuts Two System-Logic Chips
After
creating a new line of embedded MIPS processors, IDT is now
rolling out core-logic chips to support them. The RC64145
and RC32134 are for 64-bit and 32-bit chips, respectively,
and both include an SDRAM controller, PCI interface, multichannel
DMA controller, timer, UARTs, parallel port, and interrupt
logic. The major difference between the two chips is the width
of their CPU bus: 64 bits for the 64145 and 32 bits for the
32134. The '145 also supports the faster, 66-MHz PCI transactions.
More subtly,
the 32-bit chip gates memory directly onto the host processor's
data bus, while on the '145, data passes through the part.
This is because the 64-bit SysAD bus common to workstation-class
MIPS CPUs does not support data sizing, high-impedance signals,
or variable slave timing. IDT's new 32364 processor bus, in
contrast, was designed specifically to support these features,
making it easier to integrate into typical embedded systems.
Samples
of both are available now; production is in 2Q99. Prices are
a reasonable $20 ('134) and $41 ('145) in 10,000-unit quantities.
IDT's 64145 is a dead ringer for Galileo's GT-64120 but without
the I2O support nor the ability to split the 64-bit PCI into
two buses. At about $20 less expensive, that's probably a
fair tradeoff in IDT's favor.
Galileo
Announces System Logic for PowerPC
Galileo
Technology (http://www.galileot.com)
has extended its line of a half-dozen system-logic chips for
MIPS processors with a new pair for PowerPC chips. The GT-64130
and '131 are similar to Galileo's existing core-logic chips
but work with the PowerPC 603e, 740, 750, and 860- series
processors from IBM and Motorola.
Both
the '130 and the '131 add a 64-bit SDRAM interface, a DMA
controller, I2O-compatible interrupts, and one ('131) or two
('130) 32- bit, 66-MHz, PCI buses. On the '130, the two PCI
interfaces may be ganged to create a single 64-bit interface.
The so-called Universal PCI interfaces accept both 3.3-V and
5-V logic levels and comply with CompactPCI hot-swap requirements.
Galileo's
two new products move it into competition with other PowerPC
core-logic suppliers V3 (see Embedded Processor Watch #5)
and Tundra. Tundra's QSpan and PowerSpan products (see Embedded
Processor Watch #25) have a lead in the market among PowerPC
users while Galileo has a track record with MIPS customers.
Galileo's prices of $54 ('131) and $65 ('130) are certainly
higher than commodity PC chip-set prices, but competitive
for embedded systems, where there are few alternatives.
Industry
Resources: Can You Finish 700 Pages in Real Time?
Addison-Wesley
publishing and Phar Lap Software (it's the name of a racehorse)
have teamed to produce a book-and-CD combination titled "Real-Time
Programming: a Guide to 32-Bit Embedded Development." Authors
Rick Grehan (formerly of Byte and Computer Design), Robert
Moote, and Ingo Cyliax have developed a resource and tutorial
for dseveloping real- time operating systems and applications
for 32-bit system. The book is bound with a "light" version
of Phar Lap's x86 tools.
The $50
book (ISBN 0-201-48540-0) is available from bookstores or
trhough the publisher by calling 800.822.6339 or visiting
