IS45S16800F-6CTLA1-TR

The IS45S16800F-6CTLA1-TR is a 128 Mbit volatile SDRAM device organized as 8M × 16 with a parallel memory interface. It delivers synchronous DRAM operation with a 166 MHz clock frequency and a 5.4 ns access time for applications that require fast, byte-parallel memory access.

Packaged in a 54‑TSOP II (0.400", 10.16 mm width), the device supports a 3.0 V to 3.6 V supply range and an operating temperature of -40°C to 85°C, making it suitable for designs needing compact board-level memory with defined performance and temperature range.

Key Features

• Memory Core 128 Mbit SDRAM organized as 8M × 16, providing parallel data paths for system memory and buffering.
• Performance 166 MHz clock frequency with a 5.4 ns access time to support responsive memory transactions.
• Interface Parallel memory interface compatible with standard parallel SDRAM controllers and legacy memory architectures.
• Power Supply voltage range of 3.0 V to 3.6 V to match common 3.3 V system power rails.
• Package 54‑TSOP II package (0.400", 10.16 mm width) for compact, surface-mount board designs.
• Operating Range Specified operating temperature from -40°C to 85°C (TA), supporting a wide ambient temperature range.

Typical Applications

• Embedded system memory — Used as main or auxiliary SDRAM in embedded platforms that require 128 Mbit of parallel volatile memory.
• Buffer and frame memory — Suitable for buffering data in subsystems that rely on parallel SDRAM access and 16‑bit data width.
• Legacy parallel memory systems — Drop-in-compatible option for designs and equipment employing parallel SDRAM interfaces and standard 54‑TSOP II footprint.

Unique Advantages

• Deterministic performance: 166 MHz clock and 5.4 ns access time provide clearly defined timing for system memory design and timing closure.
• Compact TSOP II packaging: 54‑pin TSOP II (0.400", 10.16 mm) minimizes board area while preserving standard pinout for parallel SDRAM.
• Wide voltage compatibility: 3.0 V to 3.6 V supply range aligns with common 3.3 V system rails for simplified power design.
• Broad operating temperature: Specified -40°C to 85°C operating range supports deployment across varied ambient conditions.
• Parallel 16-bit organization: 8M × 16 organization enables 16‑bit wide data transfers for straightforward integration with 16‑bit memory buses.
