SUNNYVALE, Calif. — November 20, 2002 — The Electronic Device Group of Mitsubishi Electric & Electronics USA, Inc., a leading Low-Power SRAM (LPSRAM) supplier, announced a new ultra-small, cost-effective 16-megabit (Mbit) LPSRAM that fits into a 48-ball FBGA^[1] chip-scale package with a 7.5-mm by 8.5-mm footprint. Ideal for cellular handsets and other space-constrained applications, the new device achieves the 16-Mbit density by stacking two 8-Mbit LPSRAM die into one package.

"As our customers migrate to the 16-Mbit density, they have two requirements: keep the package size small and keep the cost-per-bit down," said Tad Keeley, senior product marketing manager for SRAMs at Mitsubishi Electric & Electronics USA, Inc. "By leveraging our leading-edge packaging technology, we have produced a 16-Mbit LPSRAM in the smallest package available in the industry. We also reduced costs by leveraging our current LPSRAM process technology and have passed this benefit on to our customers."

The new 16-Mbit LPSRAM is both forward and backward compatible with Mitsubishi Electric’s 4- to 32-Mbit LPSRAM family, allowing easy migration to higher or lower density SRAMs that use the same FBGA package. The new 16-Mbit LPSRAM is also available in a 52-pin m TSOP^[2] package with a 10.49-mm by 10.79-mm footprint.

Manufactured in 0.18-m m CMOS process technology, Mitsubishi Electric’s 16-Mbit LPSRAM requires a single, 2.7-3.6 volt power supply and provides a standby current of 1 m A at 3.0 volts (typical). The LPSRAM provides access times as fast as 70 nanoseconds and operates throughout an industrial temperature range (-40 to +85 degrees Celsius) for increased durability.

Availability
Samples of the FBGA (M5M5J167WG) and m TSOP (M5M5J167KT) package versions of Mitsubishi Electric’s 16-Mbit LPSRAM are available now, with volume production scheduled for January 2003.
