Cypress Delivers Programmable System-on-Chip(TM) (PSoC(TM)) with Integrated Full-Speed USB; New Chip Provides Traditional PSoC Integration Benefits Plus USB and Cypress CapSense(TM) Technology for HID, UPS and other Applications
SAN JOSE, Calif.—(BUSINESS WIRE)—July 11, 2005—
Cypress Semiconductor Corporation (NYSE:CY) today
introduced the CY8C24794-24LFXI, the newest member of the Cypress
Programmable System-on-Chip(TM) (PSoC(TM)) mixed-signal array family.
The new product is the first PSoC device to integrate a USB 2.0 Serial
Interface Engine (SIE), offering a sophisticated USB implementation
with shorter design cycles, reduced component and bill-of-material
costs, and board space and power consumption savings. The newest PSoC
device also includes Cypress's CapSense(TM) technology, offering an
efficient solution to replace mechanical switches and controls with
simple, touch-sensitive controls. The CY8C24794-24LFXI is ideal for
human interface devices (HIDs), including mice, keyboards, gamepads
and joysticks, as well as uninterruptible power supply (UPS) and other
PC peripheral applications.
The CY8C24794-24LFXI includes a full-speed (12 Mbps) USB 2.0 SIE,
including a 0.25 percent accurate clock with an integrated oscillator
that meets USB 2.0 clocking specifications and requires no external
crystal, reducing component and pin counts. The device provides four
unidirectional endpoints and one bi-directional control endpoint to
support control, interrupt, isochronous, and bulk transfer types, as
well as flexible synchronization. It offers up to 48 analog inputs, so
no external analog multiplexer is required for applications such as
laptop touchpads using CapSense technology. In addition to six
standard PSoC configurable analog blocks and four digital blocks, it
provides 16 Kbytes of flash program storage, 1 Kbyte of SRAM data
memory and an easy-to-use, 8-channel DMA to a dedicated 256 Byte
buffer for the USB SIE.
The CY8C24794 is supported by development software that allows
basic implementation in less than an hour. This software includes a
user module that allows very rapid design implementation. The USBFS
protocol user module generates application programming interfaces
(APIs) for easy development and includes a setup wizard. The user
module and its corresponding APIs are clearly documented in a user
module datasheet. A HID module with wizard is also included.
"PSoC products provide customers with quick, embedded mixed signal
solutions. As the market leader in USB, Cypress is now offering PSoC
customers a USB interface, essentially for free," said Steve Gerber,
director of product marketing for Cypress's PSoC Business Unit. "Now
any PSoC-based solution can be seamlessly interfaced to USB with no
extra components, pins or cost."
"Cypress has combined my two favorite technologies, USB and the
PSoC architecture, to form a winning combination," said John Hyde,
author of USB Design by Example, a leading textbook on USB. "As a beta
user of the product, I appreciated the flexibility and wider range of
USB solutions that this allows me to create. The integrated tool suite
also sped development and simplified testing."
Pricing and Availability
The CY8C24794-24LFXI is available in a 56-Lead (8x8 mm) MLF
package. It operates between 3.0 V and 5.25V and from -40 to 85
degrees C. The product is in production and is priced below $2.00 each
in high-volume quantities. A high-resolution photo can be downloaded
at http://www.cypress.com/CY8C24794photo. The CY8C24794 is supported
with a CY3214-PSoCEvalUSB Evaluation Board. The CY3214-PSoCEvalUSB is
priced at $99 (suggested resale).
About the PSoC Family
PSoC devices are configurable mixed signal arrays that integrate a
fast 8-bit microcontroller with many peripheral functions typically
found in an embedded design. PSoC devices provide the advantages of an
ASIC without the ASIC NRE or turn-around time. A single PSoC device
can integrate as many as 100 peripheral functions with a
microcontroller, saving customers design time, board space and power
consumption. Customers can save from 5 cents to as much as $10 in
system costs. Easy to use development tools enable designers to select
configurable library elements to provide analog functions such as
amplifiers, ADCs, DACs, filters and comparators and digital functions
such as timers, counters, PWMs, SPI and UARTs. The PSoC family's
analog features include rail-to-rail inputs, programmable gain
amplifiers and up to 14-bit ADCs with exceptionally low noise, input
leakage and voltage offset. PSoC devices include up to 32KB of Flash
memory, 2KB of SRAM, an 8x8 multiplier with 32-bit accumulator, power
and sleep monitoring circuits, and hardware I2C communications.
All PSoC devices are dynamically reconfigurable, enabling
designers to create new system functions on-the-fly. Designers can
achieve more than 120 percent utilization of the die, in many cases,
by reconfiguring the same silicon for different functions at different
times. In the automotive PSoC LIN bus reference design, the same
digital blocks are reconfigured four times to support the different
LIN communication modes; in doing so, these blocks consume less than
10 percent of both PSoC hardware resources and MCU cycles.
Software and Support
PSoC Designer(TM), the traditional software development
environment for PSoC, is a full-featured, GUI-based design tool suite
that enables the user to configure design-in silicon with simple point
and click options. With PSoC Designer, users can code the MCU in
either C or assembly language; and debug the design using
sophisticated features such as event triggers and multiple break
points, while single-stepping through code in C or assembly or a mix
of the two.
In March of this year, Cypress introduced PSoC Express(TM), the
first embedded development tool that allows microcontroller-based
design development without Assembly language or C programming. By
operating at a higher level of abstraction and removing required
firmware development, PSoC Express enables designs to be created,
simulated and programmed to targeted PSoC devices in hours or days
instead of weeks or months. PSoC Express includes an application
generation engine as well as an input/output device catalog and
communication protocols like I2C and RS232, all of which are combined
visually by the designer to build custom solutions. Both PSoC Express
and PSoC Designer can be downloaded free of charge from the Cypress
web site at www.cypress.com/psocexpress.
The new CY3215-DK Professional Class Development Kit includes a
USB 2.0 based, full speed in-circuit emulator with a large trace
buffer, which seamlessly integrates with PSoC Designer and the user's
development board. The development kit includes everything necessary
to complete a design with the PSoC family of ICs. The easy-to-use
tools support all the advanced PSoC packages to keep the cost of
development to a minimum while providing all the features found in
tools that cost $2,500 or more. The CY3215-DK is priced at $599
(suggested resale). The CY8C24794 is supported with a
CY3214-PSoCEvalUSB Evaluation Board that connects directly to the
CY3215-DK. The CY3214-PSoCEvalUSB is priced at $99 (suggested resale).
