MT48LC16M16A2P-7E:D TR

The MT48LC16M16A2P-7E:D TR is a 256 Mbit SDRAM organized as 16M × 16 with a parallel memory interface in a 54‑pin TSOP II package. It implements fully synchronous SDR SDRAM architecture with internal pipelining and banked memory to support burst accesses and efficient row/column operation.

This device targets systems requiring PC100/PC133‑compliant SDRAM operation at a 133 MHz clock, a single 3.3 V supply range, and a commercial operating temperature range of 0 °C to 70 °C.

Key Features

• Core / Architecture  256 Mbit SDRAM organized as 16M × 16 with four internal banks and fully synchronous operation; all signals are registered on the positive edge of the system clock.
• Performance / Timing  PC100‑ and PC133‑compliant operation with a 133 MHz clock frequency, target timing grade -7E (RCD‑RP‑CL = 2‑2‑2), and an access time of 5.4 ns.
• Burst and Refresh  Programmable burst lengths (1, 2, 4, 8, or full page), auto precharge/auto refresh modes and support for standard auto refresh and self refresh functions per the datasheet feature set.
• Power  Single 3.3 V power supply (3.0 V to 3.6 V specified) for compatibility with common 3.3 V system rails.
• Interface  Parallel memory interface with LVTTL‑compatible inputs and outputs for direct system integration.
• Package  54‑pin TSOP II (0.400", 10.16 mm width) plastic package (54‑TSOP II OCPL option) optimized for standard board mounting.
• Operating Range  Commercial temperature grade specified from 0 °C to +70 °C (TA).

Typical Applications

• PC100/PC133 memory systems  Use as synchronous DRAM memory compatible with PC100 and PC133 timing targets in systems that require standard SDRAM timing.
• Embedded systems with 3.3 V rails  Parallel SDRAM memory for designs that require a single 3.3 V supply and a compact TSOP II footprint.
• Board‑level memory expansion  Component for adding 256 Mbit of parallel DRAM in boards where a 54‑pin TSOP II package is required.

Unique Advantages

• PC100/PC133 compliance: Conforms to PC100 and PC133 timing targets, enabling straightforward integration into systems specifying those standards.
• Flexible burst operation: Programmable burst lengths and internal pipelined operation allow column address changes every clock cycle for efficient sequential accesses.
• Compact TSOP II package: 54‑pin TSOP II (0.400") package provides a space‑efficient footprint for board designs requiring SMT mounting.
• Single 3.3 V supply: Operates from 3.0 V to 3.6 V, matching common system power rails to simplify power management.
• Commercial temperature grade: Rated for 0 °C to +70 °C, suitable for standard commercial environments and applications.
