The Micron Technology MT48LC16M16A2P-75IT is a 256-megabit synchronous dynamic random-access memory (SDR SDRAM) component organized as 16M x 16 bits and delivered in a 54-pin TSOP II surface-mount package. Engineered for demanding embedded environments, the device operates from a single 3.3V supply and is rated over the industrial temperature range of -40°C to +85°C. As a member of the MT48LC16M16A2 family, the -75 speed grade supports a maximum clock frequency of 133 MHz (7.5 ns cycle time), with a programmable CAS latency of 2 or 3, a four-bank architecture, and synchronous burst-mode operation. Integrated auto-refresh and self-refresh functionality reduces standby power in low-activity periods, while a standard LVTTL interface ensures straightforward integration with a wide range of host processors, microcontrollers, and FPGAs.
Typical applications include industrial automation controllers, networking line cards and routers, medical imaging instruments, and ruggedized single-board computers where reliable extended-temperature DRAM is essential. In military and aerospace subsystems, this device often serves as main memory for command-and-control processing nodes, vibration-tolerant data loggers, and legacy avionics upgrades. Procurement teams should note that the MT48LC16M16A2 is a mature DRAM product line with increasing obsolescence risk; the industrial temperature suffix (-IT) confirms wide-temperature qualification but does not equate to full military screening or conformance to MIL-STD-883 requirements. Supply continuity planning is critical, and sourcing through authorized distributors with traceable chain-of-custody helps guard against counterfeit and remarked parts, which remain a concern for any discontinued memory component in long-lifecycle programs.
