Overview of IS45S16800F-7CTLA1 – IC DRAM 128MBIT PAR 54TSOP II

The IS45S16800F-7CTLA1 is a 128 Mbit SDRAM organized as 8M × 16 with a parallel memory interface. It is a volatile DRAM device designed for systems that require synchronous parallel memory with defined timing and supply characteristics.

Key technical attributes include a 143 MHz clock frequency, 5.4 ns access time, a 3.0–3.6 V supply range, and an industrial operating temperature range of −40°C to 85°C, supplied in a 54‑pin TSOP II package (0.400", 10.16 mm width).

Key Features

  • Memory Type and Organization  Volatile SDRAM organized as 8M × 16 for a total density of 128 Mbit, suitable for temporary data storage and buffering in synchronous systems.
  • Performance  Supports a clock frequency of 143 MHz with an access time of 5.4 ns, providing deterministic synchronous access timing.
  • Interface  Parallel memory interface compatible with parallel DRAM system architectures.
  • Power  Rated for operation from 3.0 V to 3.6 V, enabling integration into 3.3 V memory power domains.
  • Package  Available in a 54‑TSOP II package (0.400", 10.16 mm width) for compact board-level footprint and surface-mount assembly.
  • Operating Temperature  Specified for −40°C to 85°C ambient operation (TA), supporting deployments that require extended temperature capability.

Typical Applications

  • Embedded Systems  Temporary program or data storage in embedded controllers and processors that use parallel SDRAM interfaces and require a 128 Mbit density.
  • Consumer Electronics  Frame buffering and working memory in consumer devices that operate on a 3.0–3.6 V supply and use TSOP II packaged DRAM.
  • Industrial Equipment  Temporary data buffering in industrial controllers and instrumentation operating across −40°C to 85°C.
  • Telecommunications and Networking  Packet buffering or transient data storage in network modules that integrate parallel SDRAM components.

Unique Advantages

  • Defined SDRAM organization: 8M × 16 arrangement provides a clear, standard memory map for system designers integrating 128 Mbit DRAM.
  • Measurable performance: 143 MHz clock rate and 5.4 ns access time allow designers to target specific timing budgets with deterministic synchronous access.
  • Wide ambient range: −40°C to 85°C operating rating enables use in temperature-challenging environments without derating package choice.
  • Standard 3.0–3.6 V supply: Compatibility with common 3.3 V power domains simplifies power system design and rail management.
  • Compact surface‑mount package: 54‑TSOP II footprint supports high-density PCB layouts while maintaining a standard pinout for parallel DRAM connections.
