Key Features

• Memory Type / Format Volatile SDRAM (DRAM) organized as 2M × 32 for a total density of 64 Mbit.
• Performance Rated clock frequency of 143 MHz with an access time of 5.4 ns to support high-speed memory transactions within its specified timing.
• Interface LVTTL memory interface for standard digital signaling at the device pins.
• Power Nominal supply voltage range of 3.0 V to 3.6 V to match common 3 V memory rails.
• Package 86-TSOP II (86-TFSOP, 0.400" / 10.16 mm width) supplier device package for compact board-level mounting.
• Operating Temperature Specified ambient temperature range from -40°C to 85°C (TA) for temperature-dependent design considerations.

Typical Applications

• Memory Expansion External SDRAM expansion where a 64 Mbit, 2M × 32 organization and LVTTL interface are required.
• High-Speed Buffering Applications that need a 143 MHz clock-rate SDRAM with 5.4 ns access characteristics for buffering or temporary data storage.
• Compact Board Designs Systems that require a small-footprint 86-TSOP II packaged DRAM for space-constrained layouts.

Unique Advantages

• Defined Density and Organization: 64 Mbit capacity in a 2M × 32 arrangement simplifies bus and address planning for mid-density memory requirements.
• Measured Timing Performance: 143 MHz clock rating and 5.4 ns access time provide quantifiable speed parameters for system timing analysis.
• Standard LVTTL Interface: LVTTL signaling enables integration with compatible digital logic levels without additional level-shifting assumptions.
• Wide Supply Tolerance: 3.0 V to 3.6 V supply range supports common 3 V system power domains.
• Industrial Temperature Range: -40°C to 85°C ambient rating supports deployment in environments requiring extended temperature operation.
• Compact TSOP II Packaging: 86-TSOP II package (0.400" / 10.16 mm width) for efficient PCB area utilization.

Why Choose IC DRAM 64MBIT PAR 86TSOP II?

The IS45S32200N-7TLA1 provides a clear combination of 64 Mbit SDRAM capacity, defined timing (143 MHz, 5.4 ns), LVTTL signaling, and an 86-TSOP II package that together support designs needing mid-density external DRAM with documented electrical and thermal limits. Its 3.0–3.6 V supply range and -40°C to 85°C operating window make it suitable for applications where those explicit voltage and temperature constraints are required.

This device is appropriate for engineers specifying external SDRAM based on capacity, pin interface, package footprint, and measurable timing parameters. The manufacturer is Integrated Silicon Solution Inc (ISSI), and technical decisions can be based on the listed specifications when evaluating suitability for a project.
