Alliance Memory Introduces Three New CMOS Synchronous DRAMs (SDRAM) Rated for the Industrial Temperature Range of -40°C to +85°C
The SDRs released today offer densities of 64 Mb (AS4C4M16S-6TIN), 128 Mb (AS4C8M16S-6TIN), and 256 Mb (AS4C16M16S-6TIN). The devices are optimized 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 new AS4C4M16S-6TIN, AS4C8M16S-6TIN, and AS4C16M16S-6TIN 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 1M, 2M, or 4M word x 16 bits with a synchronous interface, the SDRs operate from a single +3.3-V (± 0.3V) power supply and are lead (Pb)- and halogen-free.
Alliance Memory's SDRs provide programmable read or write burst lengths of 1, 2, 4, 8, or full-page, with a burst termination option. An auto pre-charge function provides a self-timed row pre-charge initiated at the end of the burst sequence. Easy-to-use refresh functions include auto- or self-refresh while a programmable mode register allows the system to choose the most suitable modes to maximize performance.
