IS45S16320F-7BLA1

The IS45S16320F-7BLA1 from Integrated Silicon Solution Inc. (ISSI) is a 512 Mbit volatile SDRAM device organized as 32M × 16 with a parallel memory interface. It delivers specified timing and power-operating ranges for system designs that require on-board DRAM in a compact ball grid array package.

This SDRAM is specified with a 143 MHz clock frequency, a 5.4 ns access time, and a supply range of 3.0 V to 3.6 V, enabling use where these electrical and timing characteristics match system requirements.

Key Features

• Memory  512 Mbit capacity organized as 32M × 16 providing a wide parallel data path for high-density memory needs.
• Technology & Type  SDRAM volatile memory in DRAM format designed for systems requiring synchronous parallel DRAM operation.
• Performance  Specified clock frequency of 143 MHz and an access time of 5.4 ns for timing-sensitive applications.
• Power  Operates from a 3.0 V to 3.6 V supply range to match common 3V-class system rails.
• Package & Mounting  Supplied in a 54-ball thin fine-pitch BGA (54-TFBGA). Supplier package reference: 54-TW-BGA (8×13), suitable for surface-mount PCB assembly.
• Environmental Range  Device operating temperature is specified from −40°C to 85°C (TA), supporting a wide commercial and industrial ambient range.
• Interface  Parallel memory interface for direct integration where parallel SDRAM is required.

Typical Applications

• Board-Level Memory Expansion  Provides 512 Mbit of parallel SDRAM density for systems that require additional DRAM capacity in a compact BGA footprint.
• System Memory Modules  Can be used as on-board DRAM in designs that operate at 3.0–3.6 V and require the defined timing characteristics.
• High-Speed Buffering  Suitable for buffering tasks where a 143 MHz clock and 5.4 ns access time meet system performance requirements.

Unique Advantages

• High-density footprint: 512 Mbit capacity in a 32M × 16 organization provides substantial memory in a single device, reducing board-level part count.
• Compact BGA package: 54-TFBGA (54-TW-BGA, 8×13) packaging enables space-efficient surface-mount designs.
• Wide operating temperature: Rated for −40°C to 85°C (TA), supporting designs across common commercial and industrial ambient conditions.
• Standard 3V supply compatibility: 3.0 V to 3.6 V supply range aligns with typical 3V system rails for straightforward power integration.
• Deterministic timing: 143 MHz clock frequency and 5.4 ns access time allow designers to plan memory timing and throughput precisely.
