1.8V Serial Quad I/O (SQI) Flash Memory
SST26WF032
Advance Information
Product Description
The Serial Quad I/O™ (SQI™) family of flash-memory devices features a 4-bit, multiplexed I/O inter-
face that allows for low-power, high-performance operation in a low pin-count package. 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 SST proprietary, high-performance
CMOS SuperFlash® technology. The split-gate cell design and thick-oxide tunneling injector attain bet-
ter reliability and manufacturability compared with alternate approaches.
The SST26WF032 significantly improves performance and reliability, while lowering power consump-
tion. This device writes (Program or Erase) with a single power supply of 1.65-1.95V. The total energy
consumed is a function of the applied voltage, current, and time of application. Since for any given volt-
age 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.
SST26WF032 is offered in both 8-contact WSON (6 mm x 5 mm), and 8-lead SOIC (200 mil) pack-
ages. See Figure 2 for pin assignments.
