General Description
The PEEL18LV8Z is a Programmable Electrically Erasable Logic (PEEL) SPLD (Simple Programmable Logic Device) that operates over the supply voltage range of 2.7V-3.6V and features ultra-low, automatic "zero" power-down operation. The PEEL18LV8Z is logically and functionally similar to Anachip's 5V PEEL18CV8 and PEEL18CV8Z. The "zero power" (25 μA max. Icc) power-down mode makes the PEEL18LV8Z ideal for a broad range of battery-powered portable equipment applications, from hand-held meters to PCMCIA modems. EE-reprogrammability provides both the convenience of fast reprogramming for product development and quick product personalization in manufacturing, including Engineering Change Orders.
The differences between the PEEL18LV8Z and PEEL18CV8Z include the addition of programmable clock polarity, p-term clock, and Schmitt trigger input buffers on all inputs, including the clock. Schmitt trigger inputs allow direct input of slow or noisy signals. Like the PEEL18CV8, the PEEL18LV8Z is a logical superset of the industry standard PAL16V8 SPLD. The PEEL18LV8Z provides additional architectural features that allow more logic to be incorporated into the design. Anachip's JEDEC file translator allows easy conversion of existing 20 pin PLD designs to the PEEL18LV8Z architecture without the need for redesign. The PEEL18LV8Z architecture allows it to replace over twenty standard 20-pin DIP, SOIC, TSSOP and PLCC packages.
