MT48LC16M16A2B4-7E:G TR

The MT48LC16M16A2B4-7E:G TR is a 256 Mbit synchronous dynamic RAM (SDRAM) organized as 16M × 16 with internal 4-bank architecture in a 54-ball VFBGA package. It implements parallel SDRAM operation with a 133 MHz clock frequency and is designed for systems requiring volatile, high-speed synchronous memory.

Key attributes include PC100/PC133-compliant timing options, programmable burst lengths, internal pipelined operation and a single 3.3 V ±0.3 V power supply, making it suitable for designs that need standard SDRAM interface and timing behavior in a compact VFBGA footprint.

Key Features

• Core / Architecture  Fully synchronous SDR SDRAM with internal, pipelined operation; all signals registered on the positive edge of the system clock.
• Memory Organization  256 Mbit organized as 16M × 16 with four internal banks (4 Meg × 16 × 4 banks as listed for the x16 device).
• Performance / Timing  133 MHz clock frequency (speed grade -7E); access time 5.4 ns and CAS latency timing option -7E (2-2-2) as documented for the 133 MHz grade.
• Burst and Refresh  Programmable burst lengths (1, 2, 4, 8, or full page), auto precharge and auto refresh; supports 8192-cycle refresh intervals described in the datasheet.
• Interface / I/O  Parallel SDRAM interface with LVTTL-compatible inputs and outputs (as noted in the device feature set).
• Power  Single supply operation at 3.0 V to 3.6 V (documented as 3.3 V ±0.3 V in the datasheet).
• Package  54-ball VFBGA package (8 mm × 8 mm ball array) for compact board-level integration.
• Operating Range  Commercial temperature rating of 0°C to +70°C (TA) as specified.

Typical Applications

• System Memory  Use as parallel SDRAM main memory in designs requiring a 256 Mbit x16 SDRAM device with PC100/PC133 timing compatibility.
• Embedded Memory Subsystems  Suitable for embedded designs that need synchronous, pipelined memory with programmable burst lengths and auto refresh features.
• Compact Board Designs  The 54-ball VFBGA (8×8) package allows space-constrained PCBs to integrate 256 Mbit SDRAM in a small footprint.

Unique Advantages

• Synchronous, pipelined operation: Internal pipelining and positive-edge clock registration enable predictable, clock-aligned behavior and per-cycle column address changes.
• PC100/PC133 timing support: Documented compliance with PC100 and PC133 timing grades and a 133 MHz speed grade (-7E) option for compatible system timing.
• Flexible burst and refresh control: Programmable burst lengths and auto refresh/auto precharge modes simplify memory access patterns and refresh management.
• Standard 3.3 V supply: Operates from a single 3.0 V to 3.6 V supply (3.3 V ±0.3 V), matching common legacy SDRAM power domains.
• Compact VFBGA package: 54-ball VFBGA (8×8) provides a dense package option for designs constrained by PCB area.
