MT48LC32M4A2 is a Micron 8MB x4 SDRAM that supports PC100 and PC133 standards, supports programmable burst lengths of 1, 2, 4, 8 or full page, supports self-refresh mode and low power self-refresh mode, supports 64ms, 4096-cycle refresh, uses LVTTL-compatible inputs and outputs, and a single power supply of +3.3V ±0.3V.
The Micron 128 Mb SDRAM family provides high‑speed synchronous DRAM in three density configurations (x4, x8, x16). All devices operate with a single +3.3 V supply, support PC100/PC133 speeds, and include features such as programmable burst lengths, auto‑precharge, and self‑refresh modes.
The datasheet details pin assignments for 54‑pin TSOP and 60‑ball FBGA packages, timing parameters, electrical characteristics, and command definitions, enabling designers to integrate the memory into a variety of 3.3 V systems.
