MT48LC32M8A2P-6A:D

MT48LC32M8A2P-6A:D is Micron’s 256-Mbit SDRAM. It is organized as 32M x 8 (256 Mbits total) and operates synchronously with a multiplexed address space and burst data transfers. The speed grade -6A indicates a roughly 6 ns cycle time (typical timings specified in the datasheet). The suffix -D usually denotes industrial temperature range (e.g., -40°C to 85°C) and Pb-free packaging; P often signals Pb-free as well. It uses standard SDRAM control signals (CS, /RAS, /CAS, /WE, CK/CKE) and data I/O in an 8-bit wide data path. Banks are typically multiple (e.g., 4 banks) to support burst and random access patterns. Voltage is the supply specified for the MT48 SDRAM family (commonly around 3.3 V for older parts; some variants are lower voltage—check the exact datasheet). Applications include system main memory, graphics buffers, and embedded memory. For exact pinout, voltages, timing parameters, and mode registers, refer to the official MT48LC32M8A2P-6A:D datasheet.
