MT48LC32M8A2P-6A IT:G

The MT48LC32M8A2P-6A IT:G is a 256 Mbit synchronous DRAM device organized as 32M × 8 with a parallel memory interface in a 54-pin TSOP II package. It implements fully synchronous SDRAM architecture with internal pipelined operation and multiple internal banks.

Targeted at systems requiring PC100/PC133-class SDRAM timing and industrial temperature operation, the device delivers high-speed operation up to 167 MHz while operating from a single 3.3 V ±0.3 V supply (3.0–3.6 V) and an industrial ambient temperature range of −40 °C to +85 °C.

Key Features

• Core / Architecture  Fully synchronous SDRAM with internal pipelined operation and multiple internal banks for hidden row access and precharge.
• Memory Organization  256 Mbit density organized as 32M × 8 with four internal banks.
• Performance / Timing  Speed grade -6A supports 167 MHz system clock with typical CL = 3 timing; access time listed as 5.4 ns and write cycle time (word/page) of 12 ns.
• Burst and Refresh  Programmable burst lengths (1, 2, 4, 8, or full page), auto precharge, auto refresh and self-refresh modes; 8192-cycle refresh supported.
• Voltage and I/O  Single 3.3 V ±0.3 V power supply with LVTTL-compatible inputs and outputs; operating supply range 3.0–3.6 V.
• Package & Mounting  54-pin TSOP II (0.400", 10.16 mm width) plastic package intended for board-level mounting.
• Industrial Temperature Range  Rated for −40 °C to +85 °C ambient (TA) for industrial applications.

Typical Applications

• PC and Legacy System Memory  Designed for systems requiring PC100/PC133-compliant SDRAM timing and synchronous operation.
• Industrial Embedded Systems  Industrial temperature rating (−40 °C to +85 °C) and standard 3.3 V supply make it suitable for industrial controllers and embedded platforms.
• Board-Level Data Buffering  Parallel interface and programmable burst lengths support buffering and burst transfer use cases in board-level memory subsystems.
• High-Speed Memory Arrays  32M × 8 organization and internal banks enable use in designs requiring moderate density synchronous DRAM.

Unique Advantages

• High clock-rate capability: Supports a 167 MHz clock (speed grade -6A), enabling low-latency synchronous memory operation when used with matching system timing.
• Flexible burst control: Programmable burst lengths (1, 2, 4, 8, full page) allow designers to optimize transfer granularity for throughput or latency.
• Industrial temperature support: Specified for −40 °C to +85 °C ambient operation to meet industrial application thermal requirements.
• Standard 3.3 V supply: Operates from a single 3.3 V ±0.3 V supply (3.0–3.6 V), simplifying power design in existing 3.3 V systems.
• Compact TSOP II footprint: 54-pin TSOP II package (0.400", 10.16 mm width) provides a compact, board-level mount option for space-constrained designs.
• Synchronous, pipelined operation: All signals registered on the positive clock edge with internal pipelining and multiple banks to improve effective throughput in burst transfers.

Why Choose MT48LC32M8A2P-6A IT:G?

The MT48LC32M8A2P-6A IT:G is a straightforward, industry-temperature SDRAM offering 256 Mbit density with synchronous, pipelined operation and PC100/PC133-class timing. Its combination of 32M × 8 organization, programmable burst lengths, and a 54-pin TSOP II package makes it appropriate for embedded and industrial designs that require standard 3.3 V operation and a compact board-level memory solution.

This device is suited to engineers specifying reliable, synchronous DRAM for systems where established SDRAM feature sets (auto refresh, self-refresh, internal banks) and industrial temperature range are required. Its clear electrical and timing characteristics simplify integration into designs that match PC100/PC133 timing or that need a 167 MHz capable memory element.
