The AS4C8M16SA-7BCNTR is a 128Mbit synchronous DRAM (SDRAM) from Quarktwin Technology Ltd., featuring a 5.4 ns access time and a clock rate of 143 MHz. It is organized as 4 banks of 2M words x 16 bits, supporting fully synchronous operation with an internal pipelined architecture. The device allows for programmable mode registers, enabling configurations for CAS latency (2 or 3), burst lengths (1, 2, 4, 8, or full page), and burst types (sequential or interleaved). The memory operates with a single +3.3V ¬± 0.3V power supply and is available in both 54-pin TSOP II and 54-ball TFBGA packages. It supports an operating temperature range of 0 to 70¬8C for commercial applications and -40 to 85¬8C for industrial applications. The AS4C8M16SA-7BCNTR is ROHS compliant and features auto refresh and self-refresh capabilities, making it suitable for high-performance PC applications requiring high memory bandwidth.
