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. SST26VF032BEUI 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 manufactured
with proprietary, high-performance CMOS SuperFlash®
technology. The split-gate cell design and thick-oxide tunneling
injector attain better reliability and manufacturability
compared with alternate approaches.
SST26VF032BEUI significantly improve performance and
reliability, while lowering power consumption. These devices
write (Program or Erase) with a single power supply of 2.3-
3.6V. The total energy consumed 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 program and has a shorter erase time, the total energy
consumed during any Erase or Program operation is less
than alternative flash memory technologies.
SST26VF032BEUI is offered in 8-lead SOIJ (5.28 mm).
See Figure 2-1 for pin assignments.
SST26VF032BEUI default at power-up has the WP#
and HOLD# pins enabled, and the SIO2 and SIO3
pins disabled, to initiate SPI-protocol operations.See
“I/O Configuration (IOC)” on page 11 for more
information about configuring WP#/HOLD# and SIO2/SIO3 pins.
