MT48LC32M8A2P-6A:D TR

The MT48LC32M8A2P-6A:D TR is a 256 Mbit synchronous DRAM organized as 32M × 8 with a parallel memory interface. It implements SDR SDRAM architecture with internal banks and pipelined operation for synchronous system clocked designs.

Designed for board-level memory applications that require a 3.0–3.6 V supply, 54-pin TSOP II packaging, and a commercial operating range of 0 °C to 70 °C, this device delivers defined timing behavior at a 167 MHz clock frequency and supports standard SDRAM control features.

Key Features

• SDR SDRAM core  Fully synchronous SDRAM architecture with all signals registered on the positive edge of the system clock.
• Memory organization  256 Mbit capacity arranged as 32M × 8 with 4 internal banks for concurrent row access and precharge management.
• Performance  Rated for 167 MHz operation (speed grade -6A) with an access time of 5.4 ns and timing suited to 3-3-3 (RCD-RP-CL) operation per the -6A grade.
• Timing and burst  Programmable burst lengths (1, 2, 4, 8, or full page) with internal pipelined operation allowing column address changes every clock cycle.
• Refresh and power modes  Auto refresh, self refresh (as noted in the datasheet options), and 64 ms / 8192-cycle refresh support for standard commercial operation.
• Interface and signaling  Parallel memory interface with LVTTL-compatible inputs and outputs.
• Supply and voltage  Single-supply operation at 3.0 V to 3.6 V (datasheet references single 3.3 V ±0.3 V operation).
• Package and mounting  54-pin TSOP II (0.400", 10.16 mm width) plastic package suitable for board-level mounting.
• Operating range  Commercial temperature grade: 0 °C to +70 °C (TA).

Typical Applications

• PC100 / PC133-compatible systems  Use where PC100 or PC133 SDRAM timing compatibility is required, leveraging the device’s -6A speed grade and SDRAM timing features.
• Board-level memory expansion  Provides 256 Mbit parallel SDRAM capacity in a compact 54-pin TSOP II package for add-on modules and memory subsystems.
• Synchronous clocked designs  Suitable for systems that use a registered, positive-edge system clock and require pipelined SDRAM operation with programmable burst lengths.

Unique Advantages

• Defined commercial temperature rating:  Operates across 0 °C to +70 °C, making it straightforward to specify for commercial-grade applications.
• Compact TSOP II package:  54-pin (0.400" / 10.16 mm width) TSOP II footprint enables high-density board integration while keeping a standard parallel interface.
• Flexible timing options:  Supports programmable burst lengths and pipelined column access to accommodate different data transfer patterns and system timing strategies.
• Standard SDRAM feature set:  Includes auto refresh, auto precharge, and self refresh modes (datasheet noted), simplifying memory management in synchronous systems.
• Industry manufacturer support:  Produced by Micron Technology, Inc., with accompanying datasheet documentation for integration and timing guidance.
