Cypress Introduces Next-Generation Low-Speed USB Microcontrollers to Reduce Component Count, Design Time and System Cost

Low-Cost enCoRe(TM) II Family Delivers Lower Power, In-System Reprogrammability and Enhanced CPU Capabilities to Simplify Keyboard, Mouse and Wireless Dongle Designs

SAN JOSE, Calif.—(BUSINESS WIRE)—Feb. 22, 2005— Cypress Semiconductor Corp. (NYSE: CY), the market share leader in USB, today introduced a new family of low-speed USB microcontrollers targeting PC human input devices, including keyboards, mice and wireless dongles. Based on Cypress's popular "M8" microcontroller architecture, the enCoRe(TM) II (enhanced Component Reduction) family offers a flash-based design that enables storage of wireless binding parameters as well as in-system reprogrammability. The new family also adds reduced power consumption and enhanced CPU capabilities.

Cypress's enCoRe USB technology features a breakthrough crystalless oscillator. By integrating the oscillator on-chip, an external crystal or resonator is no longer needed. Cypress has also integrated other external components commonly found in low-speed USB applications, including pull-up resistors, wake-up circuitry, and a 3.3V regulator. This integration results in shorter development cycles and lower system costs.

"As the worldwide leader in USB technology, customers expect Cypress to continually deliver value-added solutions," said Trevor Davis, director of marketing for Cypress's Consumer and Computation Division. "The enCoRe II products offer important new features while meeting the low-cost requirements of this competitive market."

The enCoRe-II family includes three lines of products:

-- The CY7C639xx line is the first to bring Cypress's enhanced component reduction technologies to keyboard designs. The chips are offered in 40-pin PDIP and 28-/48-pin SSOP packages, and priced starting at $1.30 in 100,000-unit quantities.

-- The CY7C638xx line of enCoRe II controllers is targeted for high-end optical mice and wireless dongles. The devices are offered in PDIP, SOIC and QSOP packages, with pricing starting at $0.90 each in 100,000-unit quantities.

-- The CY7C633xx products target low-end optical and optomechanical mice. Available in 16-pin PDIP and SOIC packages, the devices are priced starting at just $0.85 in volume.

All of the devices are sampling now with production availability in April of this year. Cypress is also providing low-cost manufacturing chip-on-board support for high-volume enCoRe II products. A low voltage, low power non-USB version of the enCoRe-II microcontroller targeting wireless applications will be available later this year.

Cypress is the world's leading supplier of USB controllers with more than one quarter of a billion units shipped worldwide.
