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.
