MT48LC4M16A2B4-6A IT:J

The MT48LC4M16A2B4-6A IT:J is a 64 Mbit SDRAM device organized as 4M × 16 with a parallel memory interface. This fully synchronous DRAM family provides pipelined internal operation and programmable burst lengths for system memory implementations.

Designed with industrial temperature operation and a compact 54-ball VFBGA package, the device is intended for applications that require high-speed parallel SDRAM in a small footprint with 3.3 V supply operation.

Key Features

• Core / Memory Architecture  64 Mbit DRAM organized as 4M × 16 with internal banks and fully synchronous operation.
• Performance  167 MHz clock frequency (speed grade -6A) with an access time of 5.4 ns and write cycle time (word/page) of 12 ns.
• Timing and Burst  Programmable burst lengths (1, 2, 4, 8, or full page) and support for pipelined column accesses; documented timing options include CL and RCD/RP settings for the family.
• Refresh and Self-Refresh  Auto refresh supported with 4K refresh cycles; self-refresh modes are specified in the device family datasheet.
• Interface  Parallel SDRAM interface with LVTTL-compatible inputs and outputs as described in the device family documentation.
• Power  Single-supply operation at 3.0 V to 3.6 V.
• Package & Mounting  54-ball VFBGA (8 mm × 8 mm) package (54-VFBGA) suitable for compact board-level mounting.
• Operating Temperature  Industrial temperature range: -40 °C to +85 °C (TA).
• Standards  Device family is documented as PC100- and PC133-compliant in the product datasheet.

Typical Applications

• Industrial Embedded Systems  Use as system memory where industrial temperature range (-40 °C to +85 °C) and a compact BGA package are required.
• Parallel SDRAM Memory Arrays  Suitable for designs that require parallel SDRAM storage with programmable burst operation and pipelined column accesses.
• Space-Constrained Board Designs  The 54-ball VFBGA (8×8 mm) package supports small-footprint layouts that need on-board SDRAM with 3.3 V supply.

Unique Advantages

• Industry-proven SDRAM architecture: Fully synchronous, pipelined operation with internal banks enables efficient memory access patterns.
• High-speed operation at 167 MHz: -6A speed grade delivers low-latency access suitable for systems requiring tighter memory timing.
• Industrial temperature rating: -40 °C to +85 °C operation supports deployment in temperature-challenging environments.
• Compact VFBGA package: 54-ball 8×8 mm VFBGA reduces board area while providing reliable solder-ball mounting for surface-mount assembly.
• Flexible burst and refresh modes: Programmable burst lengths and documented auto/self-refresh options allow tuning for system throughput and power profiles.
• Standard 3.3 V supply: Operates from 3.0 V to 3.6 V for compatibility with common system power rails.
