MT48LC8M16A2P-75 IT:G TR

The MT48LC8M16A2P-75 IT:G TR is a 128 Mbit SDRAM device organized as 8M × 16 with a parallel memory interface in a 54-pin TSOP II package. It is a fully synchronous, volatile DRAM designed for systems requiring standard SDRAM functionality and board-level memory expansion.

Targeted use cases include embedded and industrial memory applications that benefit from PC100/PC133-compliant timing, a 133 MHz clock capability, and an industrial operating temperature range for reliable operation in wider ambient conditions.

Key Features

• Core Architecture  SDR SDRAM, fully synchronous operation with registered inputs on the positive edge of the system clock and internal pipelined operation.
• Memory Organization  128 Mbit capacity organized as 8M × 16 with internal banks for hidden row access and precharge.
• Performance & Timing  PC100- and PC133-compliant timing, specified clock frequency of 133 MHz and an access time listed as 5.4 ns; programmable burst lengths (1, 2, 4, 8, or full page).
• Refresh & Power Management  Auto refresh (4K refresh cycles) and self-refresh modes including standard and low power options (low power not available on AT devices).
• Interface & Signals  Parallel memory interface with LVTTL-compatible inputs and outputs; supports auto precharge and concurrent auto precharge/auto refresh modes.
• Supply & Voltage  Single supply operation at 3.3 V nominal (specified 3.0 V to 3.6 V).
• Package & Mounting  54-pin TSOP II (0.400", 10.16 mm width) plastic package for surface-mount board-level integration.
• Operating Temperature  Industrial temperature range: –40°C to +85°C (TA).

Typical Applications

• Embedded Systems  Provides board-level DRAM memory for microcontroller- or processor-based embedded designs that require synchronous parallel memory.
• Industrial Electronics  Industrial-temperature rating supports use in factory automation, control systems, and instrumentation operating across extended ambient ranges.
• Legacy/PC-Compatible Designs  PC100/PC133-compliant timing and 133 MHz clock capability make it suitable for designs adhering to those SDRAM timing profiles.

Unique Advantages

• Industrial Temperature Range:  Rated –40°C to +85°C to support deployment in systems exposed to wider temperature variations.
• Standard SDRAM Compatibility:  PC100/PC133 compliance and fully synchronous operation simplify integration with systems designed for standard SDRAM timing.
• Flexible Burst and Refresh Options:  Programmable burst lengths and auto/self-refresh modes enable designers to optimize throughput and power behavior for different workloads.
• Single 3.3 V Supply:  Operation from a single 3.0 V–3.6 V supply streamlines power-rail design on the host PCB.
• Compact Surface-Mount Package:  54-pin TSOP II package provides a compact footprint for board-level memory expansion while maintaining standard pinout conventions.
