• Performance  Clock frequency rated to 143 MHz with an access time of 5.4 ns, enabling deterministic read/write timing for parallel DRAM applications.
• Interface  Parallel memory interface suitable for systems designed to use external DRAM in a parallel topology.
• Power  Operating supply voltage range of 3.0 V to 3.6 V to match common 3 V DRAM power rails.
• Package  90‑TFBGA package (8 × 13 ball array) for surface-mount assembly and compact board-level integration.
• Temperature Range  Rated for operation from -40°C to 85°C (TA), supporting a range of ambient operating conditions.
• Memory Format  Volatile DRAM device designed for external system memory expansion and buffering.

Typical Applications

• Embedded Systems  Provides 128 Mbit of parallel SDRAM capacity where external DRAM is required for program data or system buffers.
• Consumer and Commercial Electronics  Used as external memory in devices that implement parallel SDRAM interfaces and require moderate-density storage.
• Industrial Equipment  Suitable for equipment operating within -40°C to 85°C that requires a 3.0–3.6 V parallel DRAM solution.

Unique Advantages

• 32‑bit Memory Organization: The 4M × 32 arrangement provides a 32‑bit wide data path for parallel transfers and straightforward bus integration.
• Defined Timing Performance: 143 MHz clock rating and 5.4 ns access time give concrete timing targets for system memory design and timing closure.
• Wide Supply Range: 3.0 V to 3.6 V operation aligns with common 3 V DRAM power rails for compatibility with standard system power domains.
• Compact Ball‑Grid Package: The 90‑TFBGA (8 × 13) package provides a surface-mount form factor for space-constrained PCBs.
• Extended Ambient Range: Rated for -40°C to 85°C operation to cover a broad set of non‑automotive environmental requirements.
