The AS4C128M16D2A-25BCN from Alliance Memory is a high-speed CMOS Double-Data-Rate-Two (DDR2) synchronous dynamic random-access memory (SDRAM) with a density of 2048 Mbits. It is organized as 128Mx16, providing a 16-bit wide data I/O. This device operates at a fast clock rate of 400MHz and requires a power supply of 1.8V (VDD & VDDQ = +1.8V ± 0.1V).
Designed to comply with DDR2 DRAM key features, it includes posted CAS# with additive latency, write latency equal to read latency minus 1 tCK, Off-Chip Driver (OCD) impedance adjustment, and On Die Termination (ODT). The memory is internally configured as an 8-bank DRAM, supporting concurrent operations for higher random access rates. It utilizes a 4-bit prefetch architecture and supports burst lengths of 4 or 8 with sequential or interleave burst types.
The AS4C128M16D2A-25BCN is packaged in an 84-ball FBGA. It is available in commercial (0 ~ 85 °C) and industrial (-40 ~ 95 °C) temperature ranges. Features like Auto Refresh, Self Refresh, and programmable mode registers are included for efficient memory management. The device is JEDEC standard compliant and SSTL_18 compatible.
