概述

Description

MT51J256M32HF-70:A is a Micron DDR2 SDRAM device from the MT51J family. It provides 256 megabits of storage organized as 32M × 8, i.e., an 8-bit data path per device in multi-bank architecture. It is a synchronous, high‑frequency DRAM with burst-enabled reads/writes and standard DDR2 timing, designed for use in memory subsystems in embedded, mobile, and consumer electronics. The “HF” suffix indicates a high‑frequency variant, and “-70” denotes a specific speed grade within the MT51J line. Typical power and timing details (voltage, timing parameters, CAS latency options, bank count, package type) are defined in the official datasheet. For exact electrical specs, pinout, timing diagrams, and recommended operating conditions, refer to Micron’s MT51J256M32HF-70:A datasheet. If you need, I can summarize the key timing parameters once you share the datasheet or a link.

Equivalent

MT51J256M32HF-70:A is a Micron DDR2 SDRAM, 256M×32 (≈8Gbit) at 1.8V. There is no fixed one-to-one cross-reference; exact equivalents depend on package, timing, and voltage. To find matches, use Micron’s cross-reference tool or distributor catalogs (e.g., DigiKey/Mouser) and look for DDR2 256M×32 devices from Samsung, Hynix, Winbond with the same speed grade (-70) and timing.

Pinout

Pin count: 84-pin VFBGA (84-ball package).
Function: 256M × 32-bit high-frequency mobile SDRAM (DDR2/DDR3 family) with a 32-bit data bus, including address/command inputs, bank select, control signals (CS, RAS, CAS, WE), clock inputs, data I/O (DQ), data mask, and power/ground pins.
