General Description
The PEEL™18CV8Z is a Programmable Electrically Erasable
Logic (PEEL™) SPLD (Simple Programmable Logic Device)
that features ultra-low, automatic “zero” power-down operation.
The “zero power” (100 µA max. Icc) power-down mode makes the
PEEL™18CV8Z ideal for a broad range of battery-powered
portable equipment applications, from hand-held meters to PCM-
CIA modems. EE-reprogrammability provides both the conve-
nience of fast reprogramming for product development and quick
product personalization in manufacturing, including Engineering
Change Orders.

The PEEL™18CV8Z is logically and functionally similar to
Anachip’s 5 Volt PEEL™18CV8 and 3 Volt PEEL™18LV8Z.
The differences between the PEEL™18CV8Z and
PEEL™18CV8 include the addition of programmable clock
polarity, a product term clock, and variable width product terms in
the AND/OR Logic Array.
Like the PEEL™18CV8, the PEEL™18CV8Z is logical superset
of the industry standard PAL16V8 SPLD. The PEEL™18CV8Z
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
PEEL™18CV8Z architecture without the need for redesign. The
PEEL™18CV8Z architecture allows it to replace over twenty
standard 20-pin DIP, SOIC, TSSOP and PLCC packages.
