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.
