Silicon Storage Technology Inc. (SST) has added a 4Mbit device to its 1.8V 25WF Series SPI serial flash memory family.

The 4Mbit, small form factor SST25WF040 is intended for battery-powered, space- and height-constrained mobile applications. The SST25WF040 has a full voltage range from 1.65V to 1.95V for read and write operations and a fast read speed of 40 MHz.

According to SST, the maximum active power consumption for both read and write operations is significantly less than that of the lowest power 3V products currently on the market. Active read currents are 4mA (typical at 40MHz), standby currents are only 2?A (typical) and maximum write currents are 10mA for both program and erase operations.

The SST25WF040 is rated for industrial temperatures (-40 to 85C) and offers 100,000 read/write cycles minimum per memory block for high-endurance applications. The device is available in an industry-standard SOIC package with other smaller package options available later this year. In addition, the device is offered as Known Good Die (KGD).

Pricing starts at $1.15 each in 10,000-unit quantities.

Devices are now in volume production.
