Description
The XCR3064A CPLD (Complex Programmable Logic Device) is the second in a family of CoolRunner™ CPLDs from Xilinx. These devices combine high speed and zero power in a 64 macrocell CPLD. With the FZP design technique, the XCR3064A offers true pin-to-pin speeds of 7.5 ns, while simultaneously delivering power that is less than 100 μA at standby without the need for "turbo bits" or other power down schemes. By replacing conventional sense amplifier methods for implementing product terms (a technique that has been used in PLDs since the bipolar era) with a cascaded chain of pure CMOS gates, the dynamic power is also substantially lower than any competing CPLD. These devices are the first TotalCMOS PLDs, as
they use both a CMOS process technology and the patented full CMOS FZP design technique.
The Xilinx FZP CPLDs utilize the patented XPLA (eXtended Programmable Logic Array) architecture. The XPLA architecture combines the best features of both PLA and PAL type structures to deliver high speed and flexible logic allocation that results in superior ability to make design changes with fixed pinouts. The XPLA structure in each logic block provides a fast 7.5 ns PAL path with five dedicated product terms per output. This PAL path is joined by an additional PLA structure that deploys a pool of 32 product terms to a fully programmable OR array that can allocate the PLA product terms to any output in the logic block. This combination allows logic to be allocated efficiently throughout the logic block and supports as many as
37 product terms on an output. The speed with which logic is allocated from the PLA array to an output is only 1.5 ns, regardless of the number of PLA product terms used, which results in worst case tPD's of only 9.0 ns from any pin to any other pin. In addition, logic that is common to multiple outputs can be placed on a single PLA product term and shared across multiple outputs via the OR array, effectively increasing design density.
The XCR3064A CPLDs are supported by industry standard CAE tools (Cadence/OrCAD, Exemplar Logic, Mentor, Synopsys, Synario, Viewlogic, and Synplicity), using text (ABEL, VHDL, Verilog) and/or schematic entry. Design verification uses industry standard simulators for functional and timing simulation. Development is supported on personal computer, Sparc, and HP platforms. Device fitting uses a Xilinx developed tool, XPLA Professional (available on the Xilinx web site).
The XCR3064A CPLD is reprogrammable using industry standard device programmers from vendors such as Data I/O, BPMicrosystems, SMS, and others. The XCR3064A also includes an industry-standard, IEEE 1149.1, JTAG interface through which In-System Programming (ISP) and reprogramming of the device are supported.

Description
TinySwitch-II integrates a 700 V power MOSFET, oscillator, high voltage switched current source, current limit and thermal shutdown circuitry onto a monolithic device. The start-up and operating power are derived directly from the voltage on the DRAIN pin, eliminating the need for a bias winding and associated circuitry. In addition, the TinySwitch-II devices incorporate auto-restart, line under-voltage sense, and frequency jittering.
An innovative design minimizes audio frequency components in the simple ON/OFF control scheme to practically eliminate audible noise with standard taped/varnished transformer construction. The fully integrated auto-restart circuit safely limits output power during fault conditions such as output short circuit or open loop, reducing component count and secondary feedback circuitry cost. An optional line sense resistor externally programs a line under-voltage threshold, which eliminates power down glitches caused by the slow discharge of input storage capacitors present in applications such as standby supplies. The operating frequency of 132 kHz is jittered to significantly reduce both the quasi-peak and average EMI, minimizing filtering cost.

TinySwitch-II Features Reduce System Cost
*Fully integrated auto-restart for short circuit and open loop fault protection–saves external component costs
*Built-in circuitry practically eliminates audible noise with ordinary dip-varnished transformer
*Programmable line under-voltage detect feature prevents power on/off glitches–saves external components
*Frequency jittering dramatically reduces EMI (~10 dB)–minimizes EMI filter component costs
*132 kHz operation reduces transformer size–allows use EF12.6 or EE13 cores for low cost and small size
*Very tight tolerances and negligible temperature variation on key parameters eases design and lowers cost
*Lowest component count switcher solution
*Expanded scalable device family for low system cost
