The Micron MT48LC16M16A2TG-6A:IT is a 256-megabit synchronous DRAM (SDR) component organized as 16M x 16 bits, designed by Micron Technology for embedded systems requiring proven memory reliability. Housed in a 54-pin TSOP II surface-mount package, it operates from a single 3.3V power supply and supports clock frequencies up to 166 MHz with a CAS latency of 3 cycles, delivering fast burst-mode data transfers across a 16-bit interface. The four-bank architecture with programmable burst lengths and auto-refresh with self-refresh capability allows power-efficient, deterministic access in both active and stand-by modes. Its fully synchronous interface locks control and address inputs to a common clock edge, simplifying board-level timing design for legacy processor and FPGA interconnects.
Typical deployments span industrial automation controllers, military and aerospace mission computers, ruggedized single-board computers, medical imaging subsystems, and networking line cards where extended temperature tolerance and long lifecycle are paramount. The “IT” suffix indicates an industrial temperature rating of -40°C to +85°C, enabling reliable operation in harsh thermal environments. As a mature SDR SDRAM device, this part remains widely specified in long-lifecycle programs that cannot migrate to newer DDR architectures; procurement teams should anticipate potential obsolescence windows and secure factory-direct or authorized distribution sourcing to guarantee full traceability and lot-level testing documentation. The standard TSOP II package supports cost-effective automated assembly and field-proven solder joint reliability in moderate- to high-volume production.
