MT48LC16M8A2BB-6A:L

The MT48LC16M8A2BB-6A:L is a 128 Mbit synchronous DRAM (SDRAM) device organized as 16M × 8 with four internal banks and a parallel memory interface. It provides fully synchronous, pipelined operation with support for programmable burst lengths and hardware refresh modes.

Designed for systems that require parallel SDRAM at up to a 167 MHz clock, the device delivers predictable timing (access time listed at 5.4 ns) and is packaged in a 60-ball FBGA (8 mm × 16 mm) footprint, operating from a single 3.0 V to 3.6 V supply and specified for 0°C to +70°C ambient.

Key Features

• Memory Architecture: 128 Mbit SDRAM organized as 16M × 8 with four internal banks, providing a parallel memory interface for system-level DRAM needs.
• Performance: 167 MHz clock frequency (speed grade -6A) with timing options documented for 3-3-3 CAS/RCD/RP; access time specified as 5.4 ns and a write cycle time (word page) of 12 ns.
• Synchronous, Pipelined Operation: Fully synchronous SDRAM with all signals registered on the positive clock edge and internal pipelining that allows column address changes every clock cycle.
• Burst and Refresh Support: Programmable burst lengths (1, 2, 4, 8, or full page), auto precharge modes, auto refresh, and self-refresh modes as described in the device documentation.
• Electrical: Single 3.3 V ±0.3 V power supply range (3.0 V to 3.6 V) with LVTTL-compatible inputs and outputs.
• Package: 60-ball FBGA (8 mm × 16 mm) package (60-FBGA) for compact board-level integration.
• Operating Conditions: Commercial temperature range of 0°C to +70°C (TA) as specified in the product data.

Typical Applications

• Embedded memory subsystems — Use as parallel SDRAM for system memory expansion where a 128 Mbit density and 3.3 V supply are required.
• Legacy parallel-memory designs — Drop-in parallel SDRAM solution in designs that use a 60-ball FBGA footprint and synchronous DRAM timing.
• High-throughput buffering — Suitable for buffer memory roles that leverage programmable burst lengths and internally pipelined, banked operation at up to 167 MHz.

Unique Advantages

• Standard SDRAM timing options: Documented speed-grade timing (including -6A at 167 MHz with 3-3-3 timings) for predictable system integration and timing closure.
• Flexible burst control: Programmable burst lengths and auto precharge capabilities simplify controller design for sequential access patterns.
• Power and signal compatibility: Single 3.3 V supply and LVTTL-compatible I/O support common system voltage domains and interface requirements.
• Compact FBGA package: 60-ball FBGA (8×16 mm) enables space-efficient board layouts while preserving routing access for parallel memory buses.
• Built-in refresh management: Auto refresh and self-refresh modes reduce external refresh control complexity and support stable data retention.
