voltage supply; only one is necessary to read
and write
GENERAL DESCRIPTION
The Miniature Card is an expansion card that pro-
vides a low cost, low power, high-performance, small
form factor solution for data and file storage to the
portable, handheld market, which includes audio,
digital film, wireless, and PDA (Portable Digital
Assistant) applications.
Miniature cards can be easily “snapped” into the back
of an electronic system and can be readily removed
and replaced by end users. AMD’s 3 V Flash Miniature
Cards are manufactured using AMD’s industry leading
3.0 volt-only, single-power-supply Am29LV081 Flash
Memory device, ensuring high reliability and excellent
performance. The Miniature Card is less than 30% of
the size of a PCMCIA memory card. Applications
include digital voice recorders, pocket PCs and intelli-
gent organizers, smart cellular telephones, voice and
data messaging pagers, digital still cameras and por-
table instrumentation equipment.
The Miniature Card specification will be defined by
PCMCIA as of October 1997. The participating associ-
ation members include major Flash memory vendors
and leading consumer electronics OEMs. The goal of
the Miniature Card specification is to promote an open,
