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. SST26VF020A also supports
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.
SST26VF020A significantly improves performance and
reliability, while lowering power consumption. These
devices write (Program or Erase) with a single-power
supply of 2.3V-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.
