NINE SHIPS W91284PIC PERIPHERAL CHIP FOR HIGH SPEED IEEE 1284 PARALLEL
PORT PRINTERS, SCANNERS, CAMERAS AND PERIPHERALS
New IEEE 1284 Chip Allows Hardware Manufacturers to Add EPP/ECP
Capabilities to Their Devices
DIEGO, California, April 12, 1999
-- Warp Nine Engineering is now shipping the W91284PIC, a new IEEE
1284 Peripheral Interface Controller chip that allows hardware manufacturers
to add IEEE 1284 features to their devices. The IEEE 1284 standard
defines high speed bi-directional communication between the PC and
the peripheral. Speeds in excess of 1.5 Mbytes per second are possible.
The W91284PIC provides an easy way for manufacturers to add a high
speed parallel interface to their cameras, scanners, printers, and
other peripheral devices.
companies are interested in adding high-performance parallel port
support to their hardware but do not know how to get started,"
said Larry Stein, president of Warp Nine. "Most customers do
not want to worry about learning how the parallel port interface
works. All they want is a chip they can plug in and get full IEEE
1284 support. Our new chip provides this capability."
The IEEE 1284 Chip Saves Time
By using the Warp Nine W91284PIC chip, manufacturers do not have
to be concerned with the parallel port interface. "The Warp
Nine Chip allowed us to put a custom device on a PC's parallel port
without disturbing the printing operations. We didn't have to install
any extra hardware on the PC to allow communications. We simply
hooked their chip up to our processor," said Craig Brown, Senior
Design Engineer of Stellcom, a San Diego-based engineering services
company. "Their easy to implement chip and test software shaved
several weeks off of our design cycle and provided an easy, inexpensive
solution to a difficult problem." The W91284PIC incorporates
all of the IEEE 1284 and 1284.3 protocols including Device_ID, for
plug and play. The chip provides hardware support for the various
communication modes defined by the IEEE standard, Nibble, Byte,
ECP and EPP. Dual FIFOs are implemented to support burst rate matching
between the peripheral and the host. In order to provide easy implementation
the client interface to the peripheral is based upon a simple microprocessor
interface. The manufacturer does not need to know anything about
the parallel port in order to get maximum, compliant parallel port
connectivity. The W91284PIC provides some client registers to control
the basic chip functioning such as timing scalar, DMA enable, interrupt
and Centronics mode operation. Otherwise, the interface is a simple
register mapped component. From the client side, all the parallel
port data transfer is simple I/O from the transmit and receive data
For embedded applications the W91284PIC provides a convenient interface
for PC connectivity. The parallel interface is a well known, easily
implemented interface that would ensure that embedded products can
communicate with virtually 100 percent of all PC's and laptops.
Set top boxes, data acquisition devices and high speed modems are
just some of the embedded products that the W91284PIC can enhance.
Port Sharing Provided
In addition to the complete IEEE 1284-1994 standard support, the
W91284PIC has support for sharing the parallel port as defined by
IEEE standard 1284.3. This means that the peripheral can share a
single parallel port with other devices such as zip drives, scanners
and printers, in a simple manner without the problems seen today.
