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. SST26VF032B/032BA also support full com-
mand-set compatibility to traditional Serial Peripheral Inter-
face (SPI) protocol. System designs using SQI flash devices
occupy less board space and ultimately lower system costs.
• Superior Reliability
- Endurance: 100,000 Cycles (min)
- Greater than 100 years Data Retention
• Low Power Consumption:
- Active Read current: 15 mA (typical @ 104 MHz)
- Standby Current: 15 µA (typical)
• Fast Erase Time
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 tun-
neling injector attain better reliability and manufacturability
compared with alternate approaches.
- Sector/Block Erase: 18 ms (typ), 25 ms (max)
- Chip Erase: 35 ms (typ), 50 ms (max)
• Page-Program
- 256 Bytes per page in x1 or x4 mode
• End-of-Write Detection
SST26VF032B/032BA significantly improve performance
and reliability, while lowering power consumption. These
devices write (Program or Erase) with a single power supply
of 2.3-3.6V. 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 opera-
tion is less than alternative flash memory technologies.
