MT48LC16M16A2BG-7E IT:D

The MT48LC16M16A2BG-7E IT:D is a 256 Mbit synchronous DRAM (SDRAM) organized as 16M × 16 with a parallel memory interface. It implements fully synchronous, pipelined operation with internal banks and supports standard SDRAM control and refresh functions.

This device is intended for designs that require a 256 Mbit parallel SDRAM solution operating at a 133 MHz clock rate and a 3.0–3.6 V supply, offered in a 54-ball VFBGA package with an industrial temperature range of −40 °C to +85 °C.

Key Features

• Core / Architecture 4M × 16 × 4 banks organization providing 256 Mbit total capacity with internal bank architecture for row access/precharge hiding.
• SDR SDRAM Operation Fully synchronous SDRAM with all signals registered on the positive edge of the system clock and internal pipelined operation allowing column address changes each clock cycle.
• Performance / Timing 133 MHz clock frequency (PC133-compliant) with specified access time of 5.4 ns and write cycle time (word/page) of 14 ns; -7E timing grade targets 2-2-2 (RCD-RP-CL) at 133 MHz per datasheet tables.
• Memory Modes Programmable burst lengths (1, 2, 4, 8, or full page), auto precharge, auto refresh, and self refresh modes per device options.
• Power Single-supply operation with supply range 3.0 V to 3.6 V (device specified supply window).
• Package 54-ball VFBGA package (54-VFBGA, 8 mm × 14 mm footprint) for board-mounted applications.
• Operating Temperature Industrial operating temperature range: −40 °C to +85 °C (TA) as specified.
• Interface Parallel memory interface with LVTTL-compatible inputs and outputs as described in the device feature set.

Typical Applications

• System Memory Expansion Use as a 256 Mbit parallel SDRAM device for designs requiring synchronous DRAM storage and buffering in systems that accept parallel SDRAM interfaces.
• Embedded Memory Subsystem Integration into embedded platforms needing a standard SDRAM component with programmable burst lengths and internal bank management.
• Legacy Parallel SDRAM Designs Drop-in replacement for designs using 16M × 16 SDRAM organization with PC100/PC133 timing and a 54-ball VFBGA footprint.

Unique Advantages

• Synchronous, pipelined operation: Enables column addresses to change every clock cycle and supports registered timing on the positive clock edge for predictable synchronous behavior.
• PC100 / PC133-compliant timing: Documented compliance with PC100 and PC133 timing grades and a 133 MHz clock frequency for systems designed to those timing classes.
• Flexible memory modes: Programmable burst lengths and auto precharge/refresh/self-refresh options simplify control for varied access patterns and power management.
• Industrial temperature support: Specified operation from −40 °C to +85 °C to meet temperature requirements for industrial-class applications.
• Compact VFBGA package: 54-ball VFBGA (8 mm × 14 mm) provides a compact board footprint for space-constrained designs.
