Low-Power Pseudo-SRAMs Offer 16- And 32-Mbit Capacities

July 21, 2003

An ultra-low-power pseudo-SRAM (PSRAM) family with a wide operating voltage range from 2.3 to 3.6 V is available in 1Mx16 and 2Mx16 configurations. The memories are a good match for next-generation cellular phones as well as wireless, handheld, and portable applications. The 16- and 32-Mbit devices (the IS32WV16100 and 16200, respectively) are offered in 70- and 100-ns speed grades and have very low standby and operating currents, typically 50 µA and 10 mA, respectively. The company offers known-good die support and an industrial temperature-range option. The PSRAM family is socket-compatible with devices from Fujitsu, Toshiba, and NEC. In lots of 10,000 units, the 16- and 32-Mbit memories cost $3.95 and $6.95, respectively, in 48-contact mini-BGA packages. Samples and production quantities are immediately available.
