High-speed DDR SDRAM

16 August 2017 DSP, Micros & Memory

Alliance Memory introduced a new 1 Gb high-speed CMOS double data rate synchronous DRAM (DDR SDRAM) in the 66-pin TSOP II package. Offered in an industrial temperature range from -40°C to +85°C, the AS4C128M8D1-6TIN features a hard-to-find internal configuration of four banks of 32M word x 8 bits.

With a clock frequency up to 166 MHz for fast data transfer rates, the device provides a reliable drop-in, pin-to-pin compatible replacement for a number of similar solutions in industrial, medical, communications and military products requiring high memory bandwidth. The chip operates from a single +2,5 V (±0,2 V) power supply, features a power down mode to lower power consumption, and offers a data mask for write control.
