Key Features
- 256 Mbit (16M x 16-bit) SDRAM with 166 MHz clock and 6 ns cycle time for high-bandwidth embedded processor memory applications
- 54-ball BGA package in tape-and-reel format enabling automated SMT assembly in compact embedded computing and networking hardware
- 16-bit wide data bus with 4-bank architecture and commercial temperature range for cost-effective system memory in industrial and consumer designs
Applications
The MT48LC16M16A2F4-6A:GTR is used as main system DRAM in embedded Linux platforms, single-board computers, and network switches where 256 Mbit of 16-bit wide SDRAM provides adequate bandwidth for OS operation and packet buffering. Industrial HMI panels and video processing boards use this device as frame buffer memory thanks to its 166 MHz data rate and compact 54-ball BGA form factor. Consumer electronics such as set-top boxes, DSL modems, and IP cameras also deploy this SDRAM for local data buffering and firmware execution at low system cost.

Frequently Asked Questions
What clock speed and data bus width does the MT48LC16M16A2F4-6A:GTR provide for an embedded Linux application processor?
The MT48LC16M16A2F4-6A:GTR operates at up to 166 MHz with a 6 ns cycle time and a 16-bit wide data bus, delivering a peak transfer bandwidth of approximately 332 MB/s. This is sufficient for running embedded Linux kernels on 32-bit application processors at clock speeds up to 200 MHz, where the 256 Mbit (32 MB) capacity accommodates the kernel, root filesystem, and application memory simultaneously. The 4-bank architecture allows bank interleaving to reduce effective memory latency during sequential access patterns common in OS page table walks.
Which networking and industrial board designs benefit most from the MT48LC16M16A2F4-6A's 54-ball BGA and tape-and-reel packaging?
Network switch line cards, industrial gateway controllers, and Ethernet router boards benefit from the 54-ball BGA footprint of the MT48LC16M16A2F4-6A, which consumes roughly 50% less PCB area than a comparable 54-pin TSOP-II package. The tape-and-reel (:GTR suffix) format enables fully automated pick-and-place assembly at throughput rates exceeding 5,000 units per hour on modern SMT lines, reducing per-unit assembly cost in high-volume networking equipment manufacturing. Industrial control boards in factory automation and building management systems also benefit from the compact BGA for fitting 256 Mbit of SDRAM into dense multi-chip module layouts.
How does the leaded (non-RoHS) composition of the MT48LC16M16A2F4-6A:GTR affect its use in modern commercial electronics compared to lead-free SDRAM alternatives?
The MT48LC16M16A2F4-6A:GTR is described as a leaded device, meaning it falls outside standard RoHS Directive 2011/65/EU requirements for consumer electronics sold in the EU and many other markets. This makes it unsuitable for most commercial consumer products such as smartphones, tablets, and laptops where RoHS compliance is mandatory. However, industrial, military, and aerospace applications often permit leaded solder under specific exemptions, and the leaded device may offer advantages in high-reliability solder joint integrity at operating temperatures above 85°C. Designers targeting RoHS-compliant commercial products should source a lead-free SDRAM alternative such as an equivalent Alliance Memory part with an 'IT' or 'PBF' suffix to ensure regulatory compliance.
