The AS4C4M32S-7BCN from Alliance Memory is a high-speed CMOS synchronous DRAM with a density of 128 Mbits. It is internally configured as a quad 1M x 32 DRAM with 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, a clock cycle time of 6 ns, and an access time from clock of 5.4 ns. The device supports programmable CAS Latency of 2 or 3, and burst lengths of 1, 2, 4, 8, or full page. It operates from a single 3.3V ±0.3V power supply and uses an LVTTL interface.
This SDRAM is organized as four internal banks (1M x 32-bit x 4 banks), with each bank structured as 4096 rows by 256 columns by 32 bits. It supports both Auto Refresh and Self Refresh functions. The AS4C4M32S-7BCN is available in a 90-ball TFBGA package measuring 8 x 13 x 1.2mm and is Pb and Halogen Free. It is suitable for applications requiring high memory bandwidth.
The device operates within a commercial temperature range of 0°C to 70°C. It is designed for surface mount applications.
