The SST26VF016B/032B/064B family of devices from Microchip are Serial Quad I/O™ (SQI™) interface SuperFlash® memory ICs featuring a six-wire, 4-bit I/O interface that allow for low power, high performance operation in a compact low pin-count package. The use of Microchip’s SQI™ interface results in performance of up to 104 MHz and enables low-latency execute-in-place (XIP) capability with minimal processor buffer memory. These flash memory chips also support full command-set compatibility to traditional Serial Peripheral Interface (SPI) protocol.

Through the use of SuperFlash® technology these devices offer exceptional erase times that compare very favourably to other Flash memory alternatives. Sector and block erase commands are typically completed in 18 ms, full chip erase operation taking a typical 35 ms.
