To meet the demand for high-density fast CMOS SRAMs, Alliance Memory has introduced new 8Mb and 16Mb x32 devices in the 90-ball 8x13mm TFBGA package. Providing space-saving alternatives to solutions in larger 119-ball packages, the devices are optimised for networking routers and switchers, test and medical equipment, and automotive applications. Featuring access times of 10ns and data retention voltages of 1.5V minimum, the 8Mb AS7C325632-10BIN and 16Mb AS7C351232-10BIN are configured as 256Kx32 and 512Kx32, respectively.

The SRAMs provide low power consumption with operating current of 125mA typical and standby current of 4mA 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°C temperature range.

The AS7C325632-10BIN and AS7C351232-10BIN are the latest additions to Alliance Memory's full range of fast SRAMs, which include devices with densities from 64K to 16M. Fabricated using high-performance, high-reliability CMOS technology, the ICs provide reliable drop-in, pin-for-pin-compatible replacements for a number of similar solutions.

Samples and production quantities of the new fast SRAMs are available now, with lead times of eight weeks for production quantities.
