AS4C4M16SA-6TIN

The Alliance AS4C4M16SA-6TIN is a high-speed CMOS synchronous DRAM with a capacity of 64 Mbits. It is internally configured as 4 Banks of 1M word x 16 DRAM, featuring a synchronous interface where all signals are registered on the positive edge of the clock signal.

Key electrical specifications include a fast clock rate of up to 166 MHz for the -6 speed grade and 143 MHz for the -7 speed grade, with a minimum clock cycle time of 6 ns and 7 ns respectively. The access time from CLK is a maximum of 5.4 ns. It operates from a single +3.3V ± 0.3V power supply and uses LVTTL interface logic.

This SDRAM supports programmable burst lengths of 1, 2, 4, 8, or full page, with options for sequential or interleaved burst types. It also features Auto Refresh and Self Refresh capabilities, with 4096 refresh cycles required every 64ms. The device is available in a 54-pin 400 mil plastic TSOP II package and a 54-ball 8.0 x 8.0 x 1.2mm FBGA package.

Available operating temperature ranges include Commercial (0 ~ 70° C) and Industrial (-40 ~ 85° C). These devices are well-suited for applications requiring high memory bandwidth, particularly in high-performance PC applications.
