MT48LC16M16A2P-7E IT:D

The MT48LC16M16A2P-7E IT:D is a 256 Mbit synchronous DRAM organized as 16M × 16 with four internal banks and a parallel SDRAM interface. It is supplied in a 54-pin TSOP II (400 mil, 10.16 mm width) package and is offered in the -7E speed grade targeted at 133 MHz operation.

Designed for systems that require standard PC100/PC133-compliant SDRAM behavior, this device provides synchronous, pipelined operation with programmable burst lengths, auto-refresh/autoprecharge functionality and support for self-refresh (where available per device option). Electrical and environmental specs include a 3.0 V–3.6 V supply range and an industrial operating temperature of -40°C to +85°C.

Key Features

• Memory Core & Organization 256 Mbit SDRAM organized as 16M × 16 with four internal banks for improved row/column interleaving and throughput.
• Synchronous SDRAM Architecture 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.
• Performance PC100- and PC133-compliant behavior with a clock frequency of 133 MHz for the -7E speed grade and an access time listed at 5.4 ns. CAS latency timing options are defined in the product data for the -7E grade.
• Burst & Access Modes Programmable burst lengths (1, 2, 4, 8, or full page), auto precharge and concurrent auto precharge/auto refresh modes to simplify memory sequencing.
• Refresh & Low-Power Modes Auto refresh and self-refresh capability (self-refresh not available on AT device variants) with 8K refresh cycles supported for the 256 Mb parts.
• Power Single-supply operation at 3.0 V–3.6 V (3.3 V ±0.3 V) suitable for standard 3.3 V SDRAM systems.
• Interface & I/O LVTTL-compatible inputs and outputs with a parallel SDRAM interface suitable for standard memory controller integration.
• Package & Temperature 54-pin TSOP II (400 mil) package (10.16 mm width) and industrial operating temperature range of -40°C to +85°C.
• Timing & Write Recovery Write cycle / page write recovery time of 14 ns as specified for this device.

Typical Applications

• PC100/PC133 Memory Subsystems — Use as synchronous DRAM in memory subsystems where PC100/PC133 timing compliance is required.
• Industrial Embedded Systems — Industrial temperature range (-40°C to +85°C) makes this device suitable for embedded platforms operating in extended-temperature environments.
• High‑throughput Parallel Memory Interfaces — Parallel SDRAM interface and internal bank architecture support designs needing pipelined, burst-access memory.

Unique Advantages

• Standardized PC100/PC133 support: Ensures compatibility with systems expecting PC-class SDRAM timing and behavior.
• Flexible burst and refresh modes: Programmable burst lengths plus auto-refresh and self-refresh options simplify controller design and memory management.
• Industrial temperature rating: -40°C to +85°C operation supports deployment in harsher environments than commercial-temperature parts.
• Compact, industry-standard package: 54-pin TSOP II (400 mil) package provides a space-efficient footprint for board-level integration.
• Synchronous, pipelined operation: Column address changes every clock cycle and internal banks improve effective throughput for burst and random access patterns.
• Common 3.3 V supply: Operates from 3.0 V–3.6 V, aligning with standard 3.3 V system power rails.
