MT48LC4M16A2P-7E:G TR

The MT48LC4M16A2P-7E:G TR is a 64 Mbit synchronous DRAM device organized as 4M × 16 with a parallel memory interface. It implements fully synchronous, pipelined SDRAM architecture and is specified for commercial operating temperatures.

Designed for systems requiring PC66/PC100/PC133-compatible SDRAM operation, the device offers programmable burst lengths, internal banked operation and LVTTL-compatible I/O to support board-level memory expansion and legacy PC-class memory applications.

Key Features

• Core and Timing  Fully synchronous SDRAM with all signals registered on the positive edge of the system clock; specified for PC66, PC100 and PC133 operation with a 133 MHz clock frequency and access time of 5.4 ns.
• Memory Organization  64 Mbit total capacity organized as 4M × 16 with 4 internal banks to improve row access and precharge efficiency.
• Burst and Access Modes  Programmable burst lengths of 1, 2, 4, 8 or full page; supports Auto Precharge (including Concurrent Auto Precharge) and Auto Refresh modes for flexible memory sequencing.
• Refresh and Self-Refresh  4,096-cycle refresh with a 64 ms refresh interval; supports both standard and low-power self-refresh modes.
• I/O and Signaling  LVTTL-compatible inputs and outputs for controller compatibility with common logic families.
• Power  Single-supply operation at +3.3 V nominal with an allowed supply range of 3.0 V to 3.6 V.
• Performance Parameters  Write cycle time (word/page) specified at 14 ns, supporting high-throughput parallel transfers in PC-class timing modes.
• Package and Temperature  Supplied in a 54-pin TSOP II (0.400", 10.16 mm width) package and rated for commercial ambient operation from 0 °C to 70 °C.

Typical Applications

• PC and legacy system memory  Use as on-board SDRAM for PC100/PC133-compatible designs and legacy memory subsystems requiring parallel SDRAM.
• Board-level memory expansion  Ideal for adding synchronous parallel DRAM capacity on printed circuit boards where a 54-pin TSOP II footprint is required.
• Commercial electronic equipment  Suitable for commercial-temperature systems needing a 64 Mbit SDRAM solution with standard self-refresh and auto-refresh support.

Unique Advantages

• Synchronous, pipelined architecture: Internal pipelined operation and positive-edge clock registration enable predictable timing and column-level throughput.
• Flexible burst and refresh control: Programmable burst lengths and multiple refresh/self-refresh modes allow tailoring of memory behavior to system timing and power needs.
• PC-class compatibility: Compliance with PC66/PC100/PC133 timing profiles and 133 MHz clocking simplifies integration into systems designed around these standards.
• Standard 3.3 V supply: Single +3.3 V supply range (3.0 V to 3.6 V) eases power-domain integration on conventional boards.
• Compact TSOP II package: 54-pin 0.400" TSOP II package provides a dense, board-level footprint for space-constrained designs.
• LVTTL-compatible I/O: Logic-level compatibility for straightforward interfacing to common memory controllers and system logic.
