Texas Instruments Inc. has announced what it declares as the industry's first high-temperature, non-volatile flash memory for harsh environments. The SM28VLT32-HT has an operational capacity of 4MB and eliminates the need for costly up-screening and qualification testing of industrial-grade components for temperature ranges outside data sheet specifications, noted the firm.

The device allows data logging at extreme temperatures and is guaranteed for at least 1,000 hours of operating life in harsh environment applications such as oil and gas exploration, heavy industrial and avionics. TI added that the device is qualified to work in temperatures ranging from -55C to 210C.

According to the company, the device is tested across the entire temperature range to provide robust read/write operation over the device's operating life. In addition, it eliminates the need for external parts allowing manufacturers to develop applications for harsh environments quickly and safely, and cuts development, testing and qualification time by six months, boasted TI.

TI indicated that the device comes in either a ceramic flat pack or in Known Good Die (KGD). The SM28VLT32-HT allows small package integration into multi-chip modules for systems with limited board space. Likewise, its SPI interface simplifies design and packaging, and reduces pin count.

The SM28VLT32-HT is sampling in an 8 x 25mm ceramic flat pack, with volume quantities available in 1Q13.
