Alliance Memory adds fast SRAMs in 90-Ball TFBGA
To meet the demand for high-density fast complementary metal-oxide semiconductor (CMOS) static random access memories (SRAMs), Alliance Memory has introduced eight and 16Mbit x 32 devices in the 90-ball 8.0 x 13mm thin-profile, fine-pitch ball grid array (FBGA) package.
Providing space-saving alternatives to larger 119-ball packages, the 8Mbit AS7C325632-10BIN and 16Mbit AS7C351232-10BIN SRAMs are optimised for networking routers and switchers, test and medical equipment, and automotive applications, says Alliance Memory. They have access times of 10ns and data retention voltages of 1.5V minimum. The 8Mbit AS7C325632-10BIN and 16Mbit AS7C351232-10BIN are configured as 256k x 32 and 512k x 32, respectively.
The SRAMs provide low power consumption with operating current of 125mA, typical and standby current of 4.0mA typical. The devices operate from a single power supply of 3.3V and offer tri-state output. The RoHS-compliant and halogen-free components operate over a -40 to +85 degree C temperature range.
The AS7C325632-10BIN and AS7C351232-10BIN have been added to Alliance Memory’s range of fast SRAMs, which include devices with densities from 64k to 16M. Fabricated using high-performance, high-reliability CMOS technology, the integrated circuits (ICs) provide reliable drop-in, pin-for-pin-compatible replacements for a number of similar solutions, says the company.
Samples and production quantities of the new, fast SRAMs are available now, with lead times of eight weeks for production quantities.
Alliance Memory is a worldwide provider of critical and hard-to-find dynamic random access memory (DRAM) and SRAM ICs for the communications, computing, consumer electronics, medical, automotive, and industrial markets. The company’s product range includes DRAMs and SRAMs with commercial, industrial, and automotive operating temperature ranges and densities from 64kbit to 8Gb. Privately-held, Alliance Memory maintains headquarters in San Carlos, California, and regional offices in Europe, Asia, and South America.
