MT48LC16M8A2P-75:G

The MT48LC16M8A2P-75:G is a 128 Mbit SDR SDRAM organized as 16M × 8 with a parallel memory interface in a 54-pin TSOP II package. It implements fully synchronous, pipelined SDRAM architecture with internal banks and programmable burst lengths for systems that require standard PC100/PC133-compatible SDRAM operation.

Typical use cases include systems requiring a compact, socketable parallel DRAM solution running at 133 MHz clock rates, where 3.3 V supply operation and commercial temperature range (0°C to 70°C) are appropriate.

Key Features

• Core & Architecture Fully synchronous SDR SDRAM with internal, pipelined operation and multiple internal banks to support efficient row access and precharge management.
• Memory Capacity & Organization 128 Mbit capacity organized as 16M × 8 with 4 internal banks.
• Performance & Timing PC100- and PC133-compliant speed grade (-75) with a clock frequency of 133 MHz and specified access characteristics; programmable burst lengths (1, 2, 4, 8, or full page).
• Refresh & Self-Refresh Supports auto refresh and standard self-refresh modes (low-power self-refresh option noted in datasheet where available); 4K refresh cycle support per device configuration.
• Interfaces & I/O Parallel memory interface with LVTTL-compatible inputs and outputs; all signals registered on the positive edge of the system clock.
• Power & Voltage Single-supply operation at 3.3 V (3.0 V to 3.6 V range).
• Package & Temperature Available in 54-pin TSOP II (0.400", 10.16 mm width) package; commercial operating temperature range 0°C to +70°C.

Typical Applications

• PC100/PC133 memory systems — Use as synchronous parallel DRAM for systems designed around PC100/PC133 timing and interfaces.
• Embedded systems — Provides a 128 Mbit SDRAM option for embedded designs that require a parallel memory interface and 3.3 V supply.
• Legacy hardware maintenance — Suitable for board-level replacement or repair where 54-pin TSOP II footprint and 16M × 8 organization are required.
• Board-level modules — Fits compact TSOP II designs needing standard SDRAM features such as programmable burst lengths and internal banks.

Unique Advantages

• PC100/PC133 compliance: Ensures compatibility with systems designed to those timing classes using the -75 speed grade at 133 MHz.
• Fully synchronous, pipelined operation: Column addresses can be changed each clock cycle, enabling predictable, clocked interface behavior.
• Internal bank architecture: Multiple internal banks help hide row access and precharge timing, improving effective throughput for burst transfers.
• Flexible burst operation: Programmable burst lengths (1, 2, 4, 8, full page) accommodate different access patterns and system requirements.
• Compact board integration: 54-pin TSOP II package (400 mil, 10.16 mm width) offers a standardized footprint for board-level assembly.
• Standardized voltage: Single 3.3 V supply (3.0 V to 3.6 V) simplifies power rail design for compatible systems.
