Overview of IC DRAM 128MBIT PAR 86TSOP II – 128 Mbit SDRAM, 86-TSOP II
The IC DRAM 128MBIT PAR 86TSOP II is a 128 Mbit volatile memory device implemented as SDRAM with a parallel interface and a 4M × 32 organization. It provides synchronous DRAM storage with a 143 MHz clock rating and a compact 86-TSOP II package for board-level integration.
This device is intended for designs that require parallel SDRAM capacity with deterministic timing characteristics, offering moderate operating frequency, low access latency, and a commercial temperature range for general-purpose electronic systems.
Key Features
- Memory Type and Technology Synchronous DRAM (SDRAM), volatile memory suitable for applications requiring temporary high-speed data storage.
- Capacity and Organization 128 Mbit total capacity organized as 4M × 32 bits to support wide data buses and efficient word transfers.
- Performance Rated clock frequency of 143 MHz with a specified access time of 5.4 ns and a write cycle time (word/page) of 2 ns for predictable timing behavior.
- Interface Parallel memory interface to support conventional SDRAM bus architectures and direct parallel data transfers.
- Power Supply voltage range from 3.0 V to 3.6 V, compatible with standard 3 V SDRAM power domains.
- Package 86-TSOP II package (86-TFSOP, 0.400", 10.16 mm width) for surface-mount board implementation and compact footprint.
- Operating Temperature Commercial operating range of 0 °C – 70 °C for general-purpose electronic environments.
Typical Applications
- Embedded systems Provides parallel SDRAM storage for temporary data buffers and program working memory in embedded controller designs.
- Consumer electronics Used where moderate-density parallel SDRAM is required for frame buffers, temporary data storage, or media buffering.
- Networking and communications Serves as transient packet or frame memory in systems that use parallel SDRAM interfaces.
Unique Advantages
- 128 Mbit capacity in a single device: Delivers substantial temporary storage with a 4M × 32 organization to simplify bus interfacing and memory mapping.
- Deterministic timing: Specified 5.4 ns access time and 2 ns write cycle time provide clear timing margins for system designers.
- Standard 3 V supply compatibility: Operates across a 3.0 V–3.6 V range to match common memory power rails.
- Compact TSOP II package: 86-TSOP II footprint (10.16 mm width) supports high-density board layouts while maintaining parallel interface routing.
- Commercial temperature range: Rated 0 °C–70 °C for use in mainstream electronic products and development platforms.
