Cypress Semiconductor is sampling its third generation, in-system reprogrammable clock generators. 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 provides a complete timing solution with its innovative CyberClocks timing development tool suite, which supports the company's full line of programmable clocks. CyberClocks supports the CY27EE16 by allowing the system designer to customise his requirements in realtime, under a programming simulation environment on his personal computer.
CyberClocks is development software that simplifies timing design by introducing a 'black-box' approach to configuring programmable clocks. It 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.
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, the 16 Kb of memory can be used 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.
