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 Anachips 5V PEEL18CV8 and PEEL18CV8Z. The zero power (25 μA max. Icc) power-down mode makes the PEEL18LV8Z ideal for a broad range of batterypowered 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.
