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. The SST26WF064C 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 Super-

Flash? technology. The split-gate cell design and thickoxide

tunneling injector attain better reliability and manufacturability

compared with alternate approaches.

The SST26WF064C significantly improves performance

and reliability, while lowering power consumption. These

devices write (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. For

any given voltage range, the SuperFlash technology uses

less current to program and has a shorter erase time.

Therefore, the total energy consumed during any Erase or

Program operation is less than alternative flash memory

technologies.
