SST26VF040A also supports - Active Read current: 15 mA (typical full command-set compatibility to traditional Serial 104 MHz) Peripheral Interface (SPI) protocol. System designs - Standby Current: 15 A (typical) using SQI Flash devices occupy less board space and ultimately lower system costs. Fast Erase Time: - Sector/Block Erase: 20 ms (typical), 25 ms All members of the 26 Series, SQI family are manufac- (maximum) tured with proprietary, high-performance CMOS Super- technology. The split-gate cell design and Flash - Chip Erase: 40 ms (typical), 50 ms thick-oxide tunneling injector attain better reliability and (maximum) manufacturability compared with alternate approaches. Page-Program: SST26VF040A significantly improves performance and - 256 bytes per page in x1 or x4 mode reliability, while lowering power consumption. These End-of-Write Detection: devices write (Program or Erase) with a single-power - Software polling the BUSY bit in STATUS supply of 2.3V-3.6V. The total energy consumed is a register function of the applied voltage, current and time of Flexible Erase Capability: application. Since for any given voltage range, the - Uniform 4-Kbyte sectors SuperFlash technology uses less current to program and has a shorter erase time, the total energy - Uniform 32-Kbyte overlay blocks consumed during any erase or program operation is - Uniform 64-Kbyte overlay blocks less than alternative Flash memory technologies. Write-Suspend: See Figure 2-1 for pin assignments. - Suspend program or erase operation to access another block/sector Software Reset (RST) mode Software Write Protection: - Write protection through Block Protection bits in STATUS register 2020-2021 Microchip Technology Inc.
