Cypress Extends Market-Leading USB Microcontroller Line; Announces Flexible, High-Speed Products for Standalone, Integrated Hub Applications.SAN JOSE, Calif.--(BUSINESS WIRE)--June 23, 1998--Cypress Semiconductor Corporation (NYSE NYSE See: New York Stock Exchange :CY) today extended its market-leading line of Universal Serial Bus See USB. (hardware, standard) Universal Serial Bus - (USB) An external peripheral interface standard for communication between a computer and external peripherals over an inexpensive cable using biserial transmission. (USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. ) microcontrollers with the announcement of three new product families for high-speed USB peripherals and hubs. The devices are aimed at standalone USB hub applications, hubs integrated into keyboards and monitors, and individual peripherals such as modems. Cypress developed its microcontroller line specifically for USB applications, while many other suppliers use general-purpose architectures that waste resources on functions not needed by USB applications. Cypress is therefore able to offer full USB functionality at the lowest possible cost. Cypress also integrates many different technology strengths into the devices, including SRAM See static RAM. SRAM - static random-access memory , EPROM EPROM in full erasable programmable read-only memory Form of computer memory that does not lose its content when the power supply is cut off and that can be erased and reused. , and a high-performance RISC processor. By offering hub chips with a microcontroller architecture, Cypress offers designers flexibility to customize and differentiate their end-market products. Other hub chips are not microcontroller based so designers can't implement unique functions in their products. Cypress was also the first to offer EPROM-programmability for fast, easy customization that speeds time-to-market. "Cypress has gained an advantage in the USB market by offering a technically outstanding solution and delivering products early in the USB roll-out phase," said Dan McCranie, Cypress's executive vice president of sales and marketing. "We have shipped well over a million microcontrollers to numerous peripheral manufacturers, and our devices are included in Microsoft's new USB mouse and keyboard offerings. We are going to press this advantage by continuing to introduce new product families, widening the number of applications and customers we address." New Products Meet High Speed Application Requirements Cypress's new CY7C66xxx family is designed for USB keyboards with integrated hubs. Hubs increase the number of peripherals that can attach to a PC by "splitting" one line into many. So a USB keyboard/hub connects directly into one of the PC's USB ports, and then provides four other ports through which additional peripherals can connect to the PC. The CY7C66xxx devices also offer up to 8KB of EPROM and up to 39 general-purpose I/Os. The new CY7C65xxx family is targeted at standalone hub applications, and hubs that are integrated into monitors. They provide 7- and 4-port hubs, an I2C I2C Inter-Integrated Circuit I2C Intelligent Interface Controller I2C Intelligent Controller interface for external communications, and up to 22 general-purpose I/Os. The CY7C64xxx family addresses high-speed peripheral applications such as USB modems, providing up to 36 general-purpose I/Os, I2C compatibility, and up to 8KB of EPROM. Cypress's USB microcontrollers contains a built-in watchdog timer that requires no external timer circuitry. They offer internal clock doubling from a 6 MHz crystal to insure low EMI (ElectroMagnetic Interference) An electrical disturbance in a system due to natural phenomena, low-frequency waves from electromechanical devices or high-frequency waves (RFI) from chips and other electronic devices. Allowable limits are governed by the FCC. . They also feature a zero-power "Instant On" capability to lower power consumption by 70% while providing full asynchronous Refers to events that are not synchronized, or coordinated, in time. The following are considered asynchronous operations. The interval between transmitting A and B is not the same as between B and C. The ability to initiate a transmission at either end. response. Price and Availability The new microcontrollers can be designed in now with Cypress's high-speed USB Developer's Kit, priced at $495. The kit offers real-time hardware emulation with built-in debug features, USB source code, reference designs, and documentation. The CY7C64xxx devices are available in 28-pin SOIC (Small Outline IC) A small-dimension, plastic, rectangular, surface mount chip package that uses gull-wing pins extending outward. See gull-wing lead, SOJ and chip package. and 48-pin SSOP SSOP Shrink Small Outline Package SSOP Sanitation Standard Operating Procedures (USDA) SSOP Sanitary Standard Operating Procedures SSOP Sharescan-Open Platform (Ecopy) SSOP Site Security Operational Procedures packages. The CY7C65xxx devices come in 28-pin PDIP (Plastic DIP) See DIP. and SOIC packages as well as 48-pin PDIPs and SSOPs. The CY7C66xxx products are packaged in 48-pin PDIPs and 48- and 56-pin SSOPs. The devices will sample in July, with production scheduled for August. Pricing ranges from $3.00 to $4.50 in low volumes.
