SST adds 1.8V 4Mbit serial flash device

SST has added to its 1.8V 25WF series SPI serial flash memory family the 4Mbit, small form factor SST25WF040 device.

The SST25WF040 has a full voltage range from 1.65V to 1.95V for read and write operations and a fast read speed of 40MHz.

Active read currents are 4mA (typical at 40MHz), standby currents are only 2µA (typical) and maximum write currents are 10mA for both program and erase operations.

The device is rated for industrial temperatures (-40 to +85 deg C) and offers 100,000 read/write cycles minimum per memory block for high-endurance applications. It is available in an industry-standard SOIC package with other smaller package options available later this year.
