MT48LC8M32B2F5-7 TR

The MT48LC8M32B2F5-7 TR is a 256 Mbit synchronous DRAM arranged as 8M × 32 with four internal banks, supplied in a 90-ball VFBGA (8 mm × 13 mm) package. It implements fully synchronous, pipelined SDRAM functionality with a parallel memory interface suitable for commercial-temperature systems.

Designed for applications requiring a 256 Mbit parallel SDRAM solution, this device delivers PC100 functionality, programmable burst lengths, and standard SDRAM command features (auto/precharge, auto-refresh, self-refresh) while operating from a single +3.3 V ±0.3 V supply.

Key Features

• Memory Core  256 Mbit SDRAM organized as 8M × 32 with 4 internal banks (2 Meg × 32 × 4 banks) for concurrent bank operation and improved access handling.
• Synchronous, Pipelined Operation  Fully synchronous design with registered inputs on the positive clock edge and internal pipelined operation that allows column addresses to change every clock cycle.
• Performance and Timing  Speed grade -7 supports a clock frequency up to 143 MHz with an access time of 6.0 ns (CL = 3); supports CAS latencies of 1, 2 and 3.
• Burst and Command Flexibility  Programmable burst lengths (1, 2, 4, 8, or full page) plus Auto Precharge, Concurrent Auto Precharge, Auto Refresh and Self Refresh modes.
• Interface and I/O  Parallel memory interface with LVTTL-compatible inputs and outputs for standard system integration.
• Power  Single +3.3 V ±0.3 V supply range (3.0 V to 3.6 V) to match common system rails.
• Package and Temperature  90-ball VFBGA package (8 mm × 13 mm footprint) with a commercial operating temperature range of 0°C to +70°C.
• Refresh and Reliability  Supports a 64 ms, 4,096-cycle refresh (15.6 μs/row) and standard SDRAM refresh commands for data retention and reliability.
• Write Cycle  Write cycle time (word page) specified at 14 ns for write timing planning.

Typical Applications

• Commercial embedded systems  Board-level memory expansion where a 256 Mbit parallel SDRAM is required for volatile data storage in commercial-temperature designs.
• PC100-compatible systems  Systems requiring PC100 functionality and standard SDRAM timing characteristics.
• Consumer electronics  Devices needing parallel SDRAM buffering and burst-read/write capability with programmable burst lengths and standard SDRAM command support.

Unique Advantages

• Flexible burst operation: Programmable burst lengths (1, 2, 4, 8, full page) allow tuning of sequential transfer behavior to match system access patterns.
• Banked architecture for hidden latency: Four internal banks enable row access/precharge hiding to improve effective throughput for interleaved accesses.
• Standard 3.3 V power rail: Single +3.3 V ±0.3 V supply simplifies integration into systems with common 3.3 V rails.
• Commercial temperature rating: Specified for 0°C to +70°C operation to match typical commercial electronic applications.
• Compact FBGA footprint: 90-ball VFBGA (8 mm × 13 mm) package provides a compact board-level memory option for dense layouts.
• Synchronous LVTTL I/O: LVTTL-compatible inputs and outputs and fully synchronous operation simplify timing design and clocked interfacing.

Why Choose IC DRAM 256MBIT PAR 90VFBGA?

The MT48LC8M32B2F5-7 TR (IC DRAM 256MBIT PAR 90VFBGA) positions itself as a practical, standards-based 256 Mbit SDRAM option for commercial systems that require a parallel synchronous memory with programmable burst modes, internal bank architecture and PC100 functionality. Its combination of 8M × 32 organization, 4 banks, and standard SDRAM command set supports common memory subsystem designs.

This device is suited to engineers and procurement teams specifying board-level SDRAM for commercial embedded and legacy systems where predictable timing (6 ns access, 143 MHz clock grade), single 3.3 V supply operation, and a compact 90-ball VFBGA package are required. The product’s standard SDRAM features and documented timing make it straightforward to validate and integrate into existing memory controllers that support parallel SDRAM interfaces.
