Description
Equivalent
MT48LC64M8A2P-75:C is a 64-Mbit × 8-bit SDRAM, 3.3 V, -75 ns. There is no single universal “equivalent.” Any drop-in should be another vendor’s 64M × 8 SDRAM with the same voltage, speed (-75 ns), and matching package/pinout. Common alternate suppliers include Samsung, Hynix, and Nanya devices. For exact part numbers, use each manufacturer’s cross-reference tool or the JEDEC database to verify compatibility.
Features
Here are the typical features of MT48LC64M8A2P-75:C (Micron):
- 64M x 8-bit SDRAM organization (512 Mb total)
- Synchronous DRAM with clocked interface (CS, RAS, CAS, WE)
- 75 ns speed grade
- 3.3 V nominal operation
- Multi-bank architecture (typical 4 banks)
- Burst mode with programmable burst length (BL4/BL8) and sequential burst
- Page-mode reads/writes
