Description
MT49H16M36BM-18:B is a Micron DRAM device in the MT49H family. It is a 576‑Megabit memory organized as 16,384,000 words by 36 bits (32 data bits plus 4 ECC) per access, which makes it a 32‑bit data path with ECC, common in embedded/mobile systems. The “-18” suffix indicates the device’s voltage/timing grade (typically around 1.8 V I/O, with a defined speed grade), while “BM” denotes the package/ RoHS-compliant variant (e.g., a ball-grid array lead‑free package). This part is designed for low‑power, high‑density DRAM in compact systems and requires a memory controller capable of handling a 36‑bit wide bus with ECC.
Key takeaway: it’s a Micron 576 Mb, 36‑bit‑wide DRAM for embedded applications, with 32 data bits + 4 ECC, 1.8 V class operation, and a RoHS/BD package. For exact timings, operating conditions, and pinout, consult the MT49H16M36BM-18:B datasheet from Micron.
