Synchronous DRAMs take temperature extremes

New from Sunrise Electronics is a range of high-performance wide-temperature-range synchronous DRAM devices for use in automotive GPS, remote communications, and industrial applications.

New from Sunrise Electronics is a range of high-performance WTR (wide temperature range) synchronous DRAM devices for use in automotive GPS, remote communications, and industrial applications.

The WTR SDRAMs offer the same functionality and compatibility as standard SDRAM devices, but operate over a much wider range of ambient temperatures (-40 to +85C) than standard SDRAM (0 to 70C).

This makes Elpida WTR SDRAMs ideal for any type of high-performance system that is subject to harsh temperature extremes.

"There is a strong demand for SDRAM modules that perform flawlessly under a wide range of environmental conditions", said Nigel Ford, Memory product manager for Sunrise Electronics.

"Elpida is responding to these demands with WTR SDRAMs that are robust enough for almost any application.

Utilising the most advanced circuit design techniques, these WTR SDRAM products offer the same performance and compatibility as standard SDRAMs, but operating under greater extremes of temperature".

Elpida's WTR SDRAMs achieve high-speed data transfer using a pipelined 133MHz synchronous DRAM architecture.

They are available in 128 and 256Mbit densities, and even with their WTR SDRAM functionality, customers are not required to implement a specialised SDRAM controller.

This simplifies testing for motherboard and system vendors who design for both standard and rugged environments.

The products are packaged in 54-pin TSOP (II).
