Atmel's Broad EPLD Product Line
Atmel major EPLD lines: PALtype SPLDs high-density V-Series CPLDs. Each particular feature that just right specific design requirements. matter diverse application, Atmel products socket.
Introduction Application Note
Atmel CPLD Products
V-Series CPLDs based 22V10type architecture provide market-leading capacity flexibility pins. ATV750/B 22V10 footprint with twice registers additional features better logic utilization. ATV2500/B offers pins, registers, product terms macro, 100% connectivity. ATV5000/V5100 offer advanced logic density 68-pin package with pins registers, product terms macro, high connectivity.
Atmel's PAL-Type Products
Atmel PAL-type family products modified version popular industry standard 16V8, 20V8, 22V10s. Already wide use, supported many development tools, these versions also offer features such quarter-power standby power. Atmel's family Flash-based devices combines proven high-performance low-power technologies. result,

Limits EPLD Designs with Atmel
Designers continuously challenged more features their products while using same board space, same time maintain decrease overall power consumption their system. meet these challenges, Atmel offers broad range high-density, low-power, cost-effective solutions enabling designers create products that "just what market ordered." Power Curve(1) Based standard architecture, which uses industry standard development tools, Atmel's EPLDs offer unique low-power feature while providing 100% connectivity. These devices processed with Atmel's proprietary 0.65-micron, electrically erasable UV-erasable memory processes.
Note: "Atmel's products benefit from quarter-power savings standby power feature device."
Power Savings
Atmel's low-power EPLDs high-performance products with significantly reduced power consumption compared standard-power devices. Save power required competing solutions. Lower power consumption allows smaller, lower cost power supplies provides lower junction temperatures that, turn, result higher system reliability.
feature provides dramatic power savings designs with standby mode ("Green PC") those that operate below MHz. Applications that combinatorial nature clock) also benefit using Atmel's low-power devices.
Quarter-Power Feature
Atmel's quarter-power devices offer lower active power than standard-power device. This feature saves power frequency, parts compatible with industry standard quarter-power devices available market today.
Low-Power Feature
Ideally suited power sensitive applications, Atmel's lowpower devices save power frequencies applying patented feature. This feature enables device power down automatically standby mode. Power Curve graph above shows Frequency curves standard-and lowpower devices. frequencies, Atmel's low-power devices automatically cycle through wake standby modes save power while standard-power device remains powered times.
"QL" Products
Atmel's quarter-power devices available with feature. These "QL" devices benefit from quarter-power savings standby power feature Atmel device-the ultimate power savings!

Limits Connectivity
Connectivity measures easily effectively signals routed between logic blocks within PLD. simple EPLDs, such industry standard 16V8/20V8/22V10, every input feedback connected every product term every macrocell-providing 100% connectivity. CPLDs, become common practice trade connectivity speed size. Atmel's CPLDs, however, global interconnect, ATV2500 Connectivity(1) architecture that combines speed highest connectivity- even 100% connectivity through pins. Atmel 24-pin V750 44-pin V2500 devices provide benefits true 100% connectivity. Every input feedback connected every product term every macrocell. This means higher utilization product density easier routing. result, design modifications easily made without changing assignments.
Note: Atmel's global architecture provides "real" 100% connectivity. Other segemented CPLD architectures provide limited connectivity, often 10-30% range, increasing chances routing difficulties design delays when changes must made.
Atmel's focus connectivity extends even further V5000/V5100 architecture. this density, practical maintain 100% connectivity. unique regional/universal structure Atmel's V5000s offers highest advantage connectivity, compared other 68-pin CPLDs. With conATV5000/5100 Architecture(1)
nectivity, V5000/V5100 provide advantage over other 68-pin CPLDs-the highest connectivity far. And, when combined with high density V5000/V5100, logic capability increases.
Note: Atmel ATV5000 universal which connects signals between four quadrants. Regional buses route signals within each quardrant.
