概要

Description

MT48LC8M16A2B4-6A:L is a Micron synchronous DRAM (SDRAM) device.
Key points:
- Density/organization: 128 Mbit total, organized as 8,388,608 words × 16 bits.
- Architecture: 4 banks typical for SDRAM; data width x16 (per device).
- Speed/voltage: -6A speed grade (roughly 6 ns access, ~166 MHz); operates around 3.3V.
- Package/finish: L suffix indicates RoHS/lead-free variant.
- Use: installed on memory modules to form a wider bus (DIMMs use multiple x16 devices to yield 64-bit wide data paths).
- Interface: synchronous with system clock; uses standard SDRAM commands (RAS, CAS, WE) and burst access.
- Application: common in older PCs/embedded systems as a DRAM component.
Note: Exact timing and electrical specs vary by package, temperature, and revision. For precise figures, consult the MT48LC8M16A2B4-6A:L datasheet.

Features

MT48LC8M16A2B4-6A:L is a 128-Mbit SDRAM with 8M × 16 organization. Key features:
- 4 banks; synchronous, clocked by the system clock (RAS/CAS, bidirectional data bus)
- Internal 2n prefetch with a 16-bit data path
- Burst length: typically BL = 4 (sequential bursts)
- CAS latency: CL = 6 (speed grade -6A)
- Maximum operation around 166 MHz (tCK ≈ 6 ns)
- Auto refresh support and standard power-down modes
- Lead-free (the “:L” suffix) and RoHS compliant
- Nominal Vcc around 3.3V (typical SDRAM supply for this density)
Note: exact electrical ranges and timing values are in the datasheet; the above reflects typical features for this part family.

Package

TSOP II (54-pin) package, SOP-54 form factor. Pb-free (lead-free) variant.

Pinout

- Pin count: 54 pins (lead-free TSOP package, -L).
- Function: 8M x 16-bit synchronous DRAM (SDRAM) with two banks and multiplexed address/data I/O, used as system memory.

Manufacturer

Manufacturer: Micron Technology, Inc.
What kind of company: An American multinational semiconductor company specializing in memory and storage technologies, including DRAM, NAND Flash, and NOR Flash. It is one of the world’s largest memory manufacturers.

Application
