SST26WF040B/040BA and SST26WF080B/ 080BA also support full command-set compatibility to tradi- tional 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 tun- neling injector attain better reliability and manufacturability compared with alternate approaches. The SST26WF040B/040BA and SST26WF080B/ 080BA significantly improves performance and reliabil- ity, while lowering power consumption. This device writes (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. 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. SST26WF040B/040BA and SST26WF080B/080BA is offered in 8-contact WDFN (6 mm x 5 mm), 8-lead SOIC (150 mil), 8-contact USON, and 8-ball XFBGA (Z-Scale™) packages. See Figure 2-1 for pin assignments. Two configurations are available upon order: SST26WF040B and SST26WF080B default at power- up has the WP# and Hold# pins enabled and SST26WF040BA and SST26WF080BA default at power-up has the WP# and Hold# pins disabled.
