AS4C16M16SA-6TIN Description

Short technical summary and product information.

The Alliance AS4C16M16SA-6TIN is a high-speed CMOS synchronous DRAM (SDRAM) with a density of 256 Mbits. It is internally configured as 4 Banks of 4M 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 and an access time from clock of 5 ns. The device operates from a single +3.3V ±0.3V power supply and utilizes an LVTTL interface. Programmable mode registers allow for flexible configuration of CAS Latency (2 or 3), Burst Length (1, 2, 4, 8, or full page), and Burst Type (Sequential or Interleaved).

This SDRAM is designed for applications requiring high memory bandwidth. It supports Auto Refresh and Self Refresh functions, with 8192 refresh cycles required every 64ms. The AS4C16M16SA-6TIN is available in a 54-pin 400 mil plastic TSOP II package and is rated for an industrial operating temperature range of -40°C to 85°C.
