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
碌A(chǔ)
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
PEEL18CV8 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.
