AS4C4M16SA-6TIN

The AS4C4M16SA-6TIN is a 64 Mbit synchronous DRAM (SDRAM) organized as 4M × 16 with a parallel memory interface in a 54‑pin TSOP II package. It provides a 166 MHz clock frequency and a 5.4 ns access time for time-sensitive memory operations.

This device is suited to designs that require a compact parallel SDRAM solution with a 3.0 V to 3.6 V supply range and an extended operating temperature range of −40°C to 85°C.

Key Features

• Core / Memory Architecture 64 Mbit SDRAM organized as 4M × 16, providing parallel DRAM memory format for systems that use conventional SDRAM organization.
• Performance 166 MHz clock frequency with a 5.4 ns access time to support fast synchronous memory access.
• Voltage / Power Operates from a 3.0 V to 3.6 V supply range, matching standard 3 V SDRAM power domains.
• Interface Parallel memory interface suitable for designs that require parallel DRAM connectivity.
• Package & Mounting Available in a 54‑TSOP II package (0.400", 10.16 mm width) for surface-mount PCB assembly.
• Operating Temperature Rated for −40°C to 85°C (TA) to support a broad range of ambient conditions.

Typical Applications

• Embedded memory subsystems — Use as a 64 Mbit parallel SDRAM component where 4M × 16 organization is required for system memory buffering.
• Legacy and industrial electronics — Fits designs that accept a 54‑TSOP II package and require operation across −40°C to 85°C.
• Board-level SDRAM expansion — Suitable for PCB implementations needing a 3.0 V–3.6 V parallel SDRAM device with 166 MHz clock capability.

Unique Advantages

• Well-defined SDRAM organization: The 4M × 16 configuration provides a clear memory mapping for designers integrating a 64 Mbit DRAM.
