MT48LC16M16A2P-7E L:D TR

The MT48LC16M16A2P-7E L:D TR is a 256 Mbit SDRAM device organized as 16M × 16 with a parallel memory interface in a 54-pin TSOP II package. It is a fully synchronous DRAM designed for systems requiring PC100/PC133-compliant synchronous memory behavior and supports pipelined, banked internal operation for efficient column and row access.

Key electrical and timing characteristics include a 133 MHz clock frequency, 3.0 V to 3.6 V supply range, an access time of 5.4 ns, and commercial operating temperature range of 0 °C to 70 °C. The device supports programmable burst lengths, auto-refresh and self-refresh modes and is provided in a 54‑TSOP II (0.400", 10.16 mm width) package.

Key Features

• Core / Architecture 16M × 16 organization with internal bank structure (4 banks), documented as 4 Meg × 16 × 4 banks for the 16M × 16 configuration.
• SDR SDRAM Operation Fully synchronous operation with all signals registered on the positive edge of the system clock and internal pipelined operation allowing column address changes every clock cycle.
• PC100 / PC133 Compliance Compliant with PC100 and PC133 timing classes; the -7E speed grade targets a 133 MHz clock frequency.
• Programmable Burst & Refresh Programmable burst lengths (1, 2, 4, 8 or full page), auto precharge, auto refresh and self-refresh modes along with an 8K refresh count.
• Timing Performance Clock frequency: 133 MHz; access time listed as 5.4 ns; write cycle time (word/page) 14 ns. Speed-grade timing options are defined in the datasheet.
• Supply & I/O Single-supply operation specified at 3.0 V to 3.6 V and LVTTL-compatible inputs/outputs as documented in the datasheet.
• Package 54-pin TSOP II plastic package (0.400" / 10.16 mm width) for standard surface-mount mounting and board-level integration.
• Operating Range Commercial operating temperature range: 0 °C to +70 °C (TA).

Typical Applications

• PC memory subsystems — Designed to meet PC100 and PC133 timing requirements for synchronous DRAM memory arrays in personal computer and similar system applications.
• Embedded systems requiring synchronous DRAM — Used where a parallel SDRAM interface with programmable burst lengths and banked internal memory improves throughput for data buffering and access patterns.
• Consumer and industrial electronics — Provides a 256 Mbit SDRAM option in a compact 54‑TSOP II package for board-level designs operating within the commercial temperature range.

Unique Advantages

• Proven PC100/PC133 compatibility: Directly supports PC100 and PC133 timing classes for legacy and standard synchronous memory designs.
• Banked, pipelined architecture: Internal banks and pipelined column access enable consecutive column changes every clock cycle to improve effective throughput.
• Flexible burst control: Programmable burst lengths (1, 2, 4, 8, full page) let designers tune transfer granularity to match system access patterns.
• Compact surface-mount package: 54‑pin TSOP II (0.400", 10.16 mm width) supports dense PCB layouts where board area and height are constrained.
• Wide supply tolerance: Operates from 3.0 V to 3.6 V, accommodating typical 3.3 V system rails and tolerance variations.
• Standard commercial temperature range: Rated for 0 °C to +70 °C for common consumer and commercial applications.
