MT48LC2M32B2P-6A IT:J

The MT48LC2M32B2P-6A IT:J is a 64 Mbit (2M × 32) synchronous DRAM (SDRAM) device in an 86-pin TSOP II package. It implements a fully synchronous, pipelined architecture with internal bank management and a parallel memory interface for system designs requiring deterministic SDRAM behavior.

Targeted at systems that require a PC100-class SDRAM solution, this part provides a 167 MHz clock rating (–6A speed grade), industrial operating range, and a single 3.0–3.6 V supply window to support reliable operation across a variety of embedded and board-level applications.

Key Features

• Core architecture — 2M × 32 organization with 4 internal banks (512K × 32 × 4 banks) for hidden row access and improved pipeline performance.
• SDR SDRAM functionality — Fully synchronous operation with all signals registered on the positive edge of the system clock; internal pipelined operation allows column address changes every clock cycle.
• Performance — Clock frequency rated at 167 MHz for the –6A grade and an access time of 5.4 ns; supports CAS latencies (CL) of 1, 2, and 3.
• Burst and refresh control — Programmable burst lengths (1, 2, 4, 8, or full page), auto precharge, auto refresh and self-refresh capabilities; 64 ms, 4096-cycle refresh supported per datasheet options.
• Interface and I/O — Parallel memory interface with LVTTL-compatible inputs and outputs for straightforward integration with legacy parallel memory controllers.
• Power — Single-supply operation: 3.0 V to 3.6 V (datasheet: 3.3 V ±0.3 V), supporting standard 3.3 V system rails.
• Timing — Write cycle time (word/page) of 12 ns and documented timing parameters for –6A speed grade (RCD, RP, CL = 18 ns).
• Package — 86-pin TSOP II (0.400", 10.16 mm width) standard footprint (86-TFSOP / 86-TSOP II), suited to compact board layouts.
• Temperature range — Specified operating temperature: –40 °C to +85 °C (TA), supporting industrial-temperature applications.

Typical Applications

• Embedded systems — Provides synchronous parallel DRAM storage for embedded controllers and board-level memory expansion where a 64 Mbit SDRAM is required.
• PC100-class memory designs — Compatible with PC100-class timing and operation for systems designed around PC100 SDRAM parameters.
• Industrial electronics — Industrial temperature rating supports use in systems operating across –40 °C to +85 °C.

Unique Advantages

• Deterministic synchronous operation — Fully synchronous design with pipelined internal operation enables consistent timing behavior for system memory architectures.
• Flexible burst control — Programmable burst lengths and auto precharge/refresh modes simplify system-level memory sequencing and improve effective throughput.
• Industrial temperature range — Specified operation from –40 °C to +85 °C supports deployment in temperature-challenging environments.
• Compact TSOP II package — 86-pin TSOP II (0.400" / 10.16 mm) footprint balances density and serviceability for board-level integration.
• Standard 3.3 V supply compatibility — Operates from 3.0 V to 3.6 V, matching common 3.3 V system rails for ease of power system design.
