ADVANCE INFORMATION
INTRODUCTION
This document contains the specifications for the
Intel
1.8 Volt Advanced+ Boot Block flash memory
family, which is optimized for low power, portable
systems. This family of products features a low
V
CC
/V
PP
operating range 1.65 V
–1.95 V for read,
program, and erase operations. In addition this
family is capable of fast programming at 12 V.
Throughout this document, the term “1.65 V” refers
to the full voltage range 1.65 V–1.95 V (except
where noted otherwise) and “V
PP
= 12 V” refers to
12 V ±5%. Section 1 and 2 provides an overview of
the flash memory family including applications,
pinouts, pin descriptions and memory organization.
Section 3 describes the operation of these products
and Section 4 contains electrical specifications.
Finally, Section 5 contains ordering information.
