概述

Description

MT41K256M8DA-125:M is a Micron DRAM device from the MT41K256M8DA family. Key points:
- Organization and capacity: 256M x 8 bits (2 Gbit total; about 256 MB).
- Type: Dynamic RAM (DRAM) with a synchronous, high-speed interface.
- Speed/grade: The “-125” suffix denotes its speed grade (roughly around 125 MHz data-rate for the device’s timing class).
- Interface and use: Primarily a memory component for system RAM in laptops, embedded boards, and other electronics, typically used with a memory controller that handles DRAM timing, refresh, and burst operations.
- Important notes: Exact voltage, timings (tRCD, tRP, tCAS, tRC), burst length, and pinout depend on the specific revision and package; refer to the MT41K256M8DA-125:M datasheet on Micron’s website for precise specs and application notes.
If you need concrete electrical specs or a pinout, please consult the official Micron datasheet for this exact part.

Features

MT41K256M8DA-125:M is Micron’s 2 Gb DDR3 SDRAM device (256 Mb × 8). Key features:
- DDR3 SDRAM, 8-bank design with 8n prefetch (BL8)
- Density/Org: 2 Gb total (256M × 8)
- Interface: standard DDR3 synchronous I/O
- Voltage: typically 1.5 V (DDR3); DDR3L variants exist at ~1.35 V
- Temperature: industrial variants available (typical: -40°C to 85°C)
- Includes standard DDR3 timing/refresh features (ZQ calibration, MR)
- Pb-free/RoHS-compliant
Note: exact speed grade (-125) denotes the device’s rated speed and may specify a particular MT/s range; consult the datasheet for precise timings and operating conditions.

Package

96-ball FBGA package.

Pinout

- Pin count: 60 pins (FBGA60)
- Function: Micron DRAM memory chip (256M × 8, i.e., 2 Gbit total) used as system RAM.
