SST26WF040B/040BA and SST26WF080B/ - Active Read current: 15 mA (typical 104 MHz) 080BA also support full command-set compatibility to tradi- - Standby current: 10 A (typical) tional Serial Peripheral Interface (SPI) protocol. System - Deep Power-Down current: 1.8 A (typical) designs using SQI flash devices occupy less board space Fast Erase Time and ultimately lower system costs. - Sector/Block Erase: 18 ms (typ), 25 ms (max) All members of the 26 Series, SQI family are manufactured - Chip Erase: 35 ms (typ), 50 ms (max) with proprietary, high-performance CMOS SuperFlash Page-Program technology. The split-gate cell design and thick-oxide tun- - 256 Bytes per page in x1 or x4 mode neling injector attain better reliability and manufacturability End-of-Write Detection compared with alternate approaches. - Software polling the BUSY bit in status register The SST26WF040B/040BA and SST26WF080B/ Flexible Erase Capability 080BA significantly improves performance and reliabil- ity, while lowering power consumption. This device - Uniform 4 KByte sectors writes (Program or Erase) with a single power supply of - Four 8 KByte top and bottom parameter overlay 1.65-1.95V. The total energy consumed is a function of blocks the applied voltage, current, and time of application. - One 32 KByte top and bottom overlay block Since for any given voltage range, the SuperFlash - Uniform 64 KByte overlay blocks technology uses less current to program and has a Write-Suspend shorter erase time, the total energy consumed during - Suspend Program or Erase operation to access any Erase or Program operation is less than alternative another block/sector flash memory technologies.
