Cypress Introduces Third Generation In-System Reprogrammable Clock Generators

1/8/2003 - Cypress Semiconductor Corporation (NYSE: CY), the world leader in timing technology solutions, announced sampling of its third generation, in-system reprogrammable clock generators, MulticlockTM CY27EE16. The new Multiclock CY27EE16 has a built-in charge pump, enabling the designer to program or reprogram the device in-system without requiring any special external programming voltage or having to resort to an external programmer. Cypress is providing a complete timing solution with its innovative CyberClocks timing development tool suite, which supports Cypress's full line of programmable clocks. CyberClocks supports the CY27EE16 by allowing the system designer to customize his requirements in real time, under a programming simulation environment on his personal computer.

The CY27EE16 is in-system programmable via an industry-standard I2C interface, and contains two Kbits of EEPROM memory for storing clock configuration data plus an additional 16 Kbits of independent EEPROM memory. System designers can use this "extra" memory to store system information -- including revision levels, service codes, software patch information or any other changeable information -- without the need for additional memory chips. In addition, designers can use the 16 Kbits of memory to create multiple clock configurations on a single device. For example, customers can store up to eight different spread-spectrum profiles for use at any given time.

"Cypress's timing solutions conserve cost and board space in a broad range of applications, from consumer electronics to communication systems," said John Wunner, marketing manager for Cypress's Timing Technology Division. "We're taking our leadership position one step further with this next generation of clocks that provide advanced functionality while radically simplifying timing design when used in conjunction with our easy-to-use CyberClocks software development tool suite."

About CyberClocks Development Software
CyberClocks development software simplifies timing design by introducing a "black-box" approach to configuring programmable clocks. While traditional software models cater to engineers who understand phase-locked loop (PLL) technology, the black-box approach of CyberClocks enables anyone, without any knowledge of the workings of a PLL, to simply specify input and output clock requirements and allow CyberClocks to compute the best configuration. CyberClocks software performs exhaustive computation on the requirements and optimizes the results to meet all the performance parameters set by the designer. The embedded design rule checking of the CyberClocks software ensures that the PLL system achieves stability under all valid programming conditions and data sheet parameters. CyberClocks integrates Cypress’s entire suite of timing software tools (CyClocksRTTM, CyClocksTM, and RoboConfigTM) into one easy-to-use package.

Pricing and Availability
Samples of the CY27EE16 are available now in a 20-pin EP-TSSOP. Pricing starts at $2.45 in quantities of 10,000. CyberClocks software is free and can be downloaded off the web today at . Select Software > Programmable Clocks.
