Alliance Memory synchronous DRAM range

Alliance Memory has introduced three, high-speed CMOS synchronous DRAMs (SDRAM) rated for the industrial temperature range of -40 to 85°C.

They offer densities of 64 MB (AS4C4M16S-6TIN), 128 MB (AS4C8M16S-6TIN) and 256 MB (AS4C16M16S-6TIN). The devices are optimised for high-temperature industrial applications, in addition to high-performance PC, communications, medical and consumer products requiring high memory bandwidth.

Packaged in a 54-pin, 400-mil plastic TSOP II, the devices offer a fast access time from clock down to 4.5 ns at a 5-ns clock cycle and clock rates of 166 MHz.

Internally configured as four banks of 1, 2, or 4 word x 16 bits with a synchronous interface, the SDRs operate from a single +3.3 V (± 0.3 V) power supply and are lead- and halogen-free.
