Microchip SST26WF064C ‘SuperFlash’ memory offers 64Mbit with reduced power consumption by combining Dual Transfer Rate (DTR, output data on both clock edges) with what the firm claims is the industry’s fastest erase times: it “completes a typical chip erase in just 35ms”.
Operating at frequencies reaching 104MHz, it also features execute-in-place (XIP), to eliminate code-shadowing on SRAM, plus a hardware-controlled reset and 4bit multiplexed I/O serial interface. All of these features are packaged in the same form factor as a standard Serial Flash device.
It supports full command-set compatibility to traditional Serial Peripheral Interface (SPI) protocol.
Program and erase are both at a single supply of 1.65-1.95V. Temperature range is -40 to +85°C.
Applications are expected in wireless and other battery-powered devices.
Designs using the SST26WF064C Flash memory can be developed using IBIS models as well as device drivers
