Product Description
• High Speed Clock Frequency
- 104 MHz max
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. SST26VF064B/064BA 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.
• Burst Modes
- Continuous linear burst
- 8/16/32/64 Byte linear burst with wrap-around
• Superior Reliability
- Endurance: 100,000 Cycles (min)
- Greater than 100 years Data Retention
• Low Power Consumption:
All members of the 26 Series, SQI family are manufac-
tured with proprietary, high-performance CMOS Super-
Flash® technology. The split-gate cell design and thick-
oxide tunneling injector attain better reliability and man-
ufacturability compared with alternate approaches.
- Active Read current: 15 mA (typical @ 104 MHz)
- Standby Current: 15 µA (typical)
• Page-Program
- 256 Bytes per page in x1 or x4 mode
• End-of-Write Detection
The SST26VF064B/064BA significantly improve per-
formance and reliability, while lowering power con-
sumption. These devices write (Program or Erase) with
a single power supply of 2.7-3.6V. 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.
