Product Description
The Serial Quad I/O™ (SQI™) family of flash-memory
devices features a six-wire, 4-bit I/O interface that
allows for low-power, high-performance operation in a
low pin-count package. SST26VF064B/064BA also
support full command-set compatibility to traditional
Serial Peripheral Interface (SPI) protocol. System
designs using SQI flash devices occupy less board
space and ultimately lower system costs.
All members of the 26 Series, SQI family are manufac-
tured with proprietary, high-performance CMOS Super-
Flash® technology. The split-gate cell design and thick-
oxide tunneling injector attain better reliability and man-
ufacturability compared with alternate approaches.
SST26VF064B/064BA significantly improve perfor-
mance and reliability, while lowering power consump-
tion. These devices write (Program or Erase) with a
single power supply of 2.3-3.6V. The total energy con-
sumed is a function of the applied voltage, current, and
time of application. Since for any given voltage range,
the SuperFlash technology uses less current to pro-
gram and has a shorter erase time, the total energy
consumed during any Erase or Program operation is
less than alternative flash memory technologies.
SST26VF064B/064BA are offered in 8-contact WDFN
(6 mm x 5 mm or 6mm x 8mm), 8-lead SOIJ (5.28 mm),
16-lead SOIC (7.50 mm), and 24-ball TBGA. See Fig-
ure 2-2 for pin assignments.
Two configurations are available upon order.
SST26VF064B default at power-up has the WP# and
HOLD# pins enabled, and the SIO2 and SIO3 pins dis-
abled, to initiate SPI-protocol operations.

SST26VF064BA default at power-up has the WP# and
HOLD# pins disabled, and the SIO2 and SIO3 pins
enabled, to initiate Quad I/O operations. See “I/O Con-
figuration (IOC)” on page 12 for more information about
configuring WP#/HOLD# and SIO3/SIO4 pins

You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page.
The last character of the literature number is the version number, (e.g., DS30000000A is version A of document DS30000000).
An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for current
devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the revision
of silicon and revision of document to which it applies.
To determine if an errata sheet exists for a particular device, please check with one of the following:
• Microchip’s Worldwide Web site; http://www.microchip.com
• Your local Microchip sales office (see last page)
