This whitepaper is a brief introduction to CY8C22x45, an enhanced product of CY8C21xxx PSoC® family.

RAID was first described by Garth Gibson, Randy Katz, and Dave Patterson of UC Berkeley in the late 1980s as a 'Redundant Array of Inexpensive Disks'. It has now become a blanket term for data storage schemes that implement redundancy and parallelism for better fault tolerance and input/output (I/O) performance than a single disk drive or 'Just a Bunch Of Disks' (JBOD). RAID commonly represents a system consisting of many storage disks that are accessed by servers through high speed Ethernet or Fiber Channel media. Disk drive I/O speed is the primary performance bottleneck in most storage systems. Generally, RAID Systems use parallel disk access and cache memories to increase the read and write performance, while using redundant disks for failure recovery to enhance fault tolerance.

CY22388/89/91 device family is part of the Cypress programmable clock generators. It is a quad PLL clock generator with complete voltage-control crystal oscillator (VCXO) solution with +/- 120 ppm. It is best suited for consumer applications and meets most of the application requirement for digital setup box, DVD recorder, and DTV. Industries leading consumer companies, such as Sony, Funai, and Hitachi have designed using this device.

CSD enables the implementation of an array of capacitive sensors through switched capacitor circuitry, an analog multiplexer, digital counting, and PWM functions.

The hardware configuration works in conjunction with high level software routines from the CSD User Module found in PSoC Designer(TM) to compensate for environmental and physical sensor variations

FleXO offers several key benefits over other common types of timing solutions. FleXO's primarily targets telecommunications and networking applications. It provides superior flexibility, cost, and lead time compared to alternative solutions while still offering excellent frequency stability and low phase noise, giving the customer an ideal balance of performance, cost, and flexibility.

Cypress’s anti-tamper memory, based on nonvolatile static RAM (nvSRAM) technology, has unique features that protect SRAM and nonvolatile data from accidental or malicious intrusion. It also provides the fastest nvSRAM function.

This white paper describes the tamper protect features implemented in the Cypress anti-tamper memory such as password protection, data destruction, functional destruction, and physical destruction. It is also possible to customize a combination of these data destruct features to suit application requirements.

The advantages of Lexmark's modulation waveform for EMI attenuation derive from its unique, patented shape, one embodiment of which is shown in Figure 1. In addition to the shape shown in Figure 1, other waveforms are covered by Lexmark patents (such as the triangular, or linear, waveform). A less efficient ‘sharkfin', or exponential, waveform as seen in Figure 2 is sometimes used.
