MT48LC2M32B2P-55:G TR

The MT48LC2M32B2P-55:G TR is a 64 Mbit SDR SDRAM organized as 2M × 32 with a parallel memory interface. It implements fully synchronous, pipelined SDRAM architecture with internal banks and programmable burst lengths to support system memory and board-level memory expansion.

Designed for commercial-temperature applications, this device operates from a 3.0 V to 3.6 V supply and targets systems requiring a 183 MHz clock frequency (‑55 speed grade) with fast access characteristics.

Key Features

• Core & memory organization — 64 Mbit capacity arranged as 2M × 32 (512K × 32 × 4 banks) for multi-bank operation and concurrent access management.
• Synchronous SDRAM architecture — Fully synchronous operation with all signals registered on the positive clock edge and internal pipelined operation to allow column address changes every clock cycle.
• Performance & timing — Specified for a 183 MHz clock frequency (‑55 speed grade) with an access time listed as 5 ns and CAS latency (CL) support of 1, 2 and 3.
• Programmable burst and refresh — Supports programmable burst lengths (1, 2, 4, 8 or full page), auto precharge, auto refresh and self refresh modes; 4096-cycle refresh available per datasheet.
• Voltage and I/O — Single 3.3 V ±0.3 V supply (3.0 V–3.6 V) with LVTTL-compatible inputs and outputs.
• Package & thermal — Available in an 86‑pin TSOP II (400 mil, 10.16 mm width) package; commercial operating temperature 0°C to +70°C.

Typical Applications

• Embedded systems — Provides parallel SDRAM storage for board-level memory in commercial-temperature embedded designs that require a 3.3 V supply and standard TSOP II footprint.
• System memory expansion — Used where a 2M × 32 SDRAM organized in four banks is required for buffering and working memory with programmable burst lengths and pipelined access.
• PC/legacy platforms — PC100‑compliant SDRAM timing options make this device suitable for legacy or existing systems expecting standard SDR SDRAM timing and interfaces.

Unique Advantages

• Synchronous pipelined operation: Internal pipelining and bank architecture enable efficient column access every clock cycle, reducing wait states in burst operations.
• Flexible burst control: Programmable burst lengths (1, 2, 4, 8, full page) allow designers to match data-transfer patterns and optimize throughput.
• Standard voltage domain: Single 3.3 V ±0.3 V supply simplifies power budgeting and compatibility with common 3.3 V logic domains.
• Multiple CAS latency support: CL = 1, 2, 3 options permit trade-offs between latency and system timing requirements.
• Industry-standard package: 86‑pin TSOP II footprint supports compact board-level implementation and established assembly processes.
• Refresh and power modes: Auto refresh and self-refresh options aid data retention and control of power/refresh management in system designs.
