High-speed SDRAM chips
23 October 2013, DSP, Micros & Memory

Alliance Memory has introduced a new line of high-speed CMOS double data rate synchronous DRAMs (DDR1 SDRAM) with densities of 64 Mb (AS4C4M16D1), 128 Mb (AS4C8M16D1), 256 Mb (AS4C16M16D1) and 512 Mb (AS4C32M16D1).

The devices provide reliable drop-in, pin-for-pin-compatible replacements for a number of similar solutions in medical, communications, industrial and consumer products requiring high memory bandwidth, and they are particularly well suited to high-performance PC applications.

Internally configured as four banks of 1M, 2M, 4M or 8M word x 16 bits with a synchronous interface, the chips operate from a single +2,5 V (±0,2 V) power supply and are lead- and halogen-free. They feature a fast clock rate of 200 MHz, a commercial temperature range of 0°C to 70°C, and are offered in the 66-pin TSOP II package with a 0,65 mm pin pitch.

The DDR1 SDRAMs provide programmable read or write burst lengths of 2, 4 or 8. 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 maximise performance.
