IS42S16800J-7BLI

The IS42S16800J-7BLI is a 128 Mbit volatile SDRAM organized as 8M × 16, manufactured by Integrated Silicon Solution Inc (ISSI). It provides parallel DRAM storage with a 143 MHz clock capability and an access time of 5.4 ns for systems that require deterministic, board-level dynamic memory.

Designed for integration where compact package size, defined timing, and a standard LVTTL interface are required, this device supports operation across a wide supply voltage range and an extended industrial temperature window.

Key Features

• Memory Core 128 Mbit SDRAM organized as 8M × 16 (DRAM, volatile) for parallel dynamic memory applications.
• Performance Clock frequency up to 143 MHz with an access time of 5.4 ns to support time-critical memory operations.
• Interface LVTTL memory interface for compatibility with board-level logic and MCU/FPGA memory controllers that use LVTTL signaling.
• Power Operates from a 3.0 V to 3.6 V supply range to match common 3 V system power rails.
• Package 54-TFBGA package (8 × 8 mm) for compact board footprint and surface-mount assembly.
• Temperature Range Rated for operation from −40 °C to 85 °C (TA) to accommodate extended-temperature environments.

Typical Applications

• Parallel SDRAM memory expansion — Provides 128 Mbit of dynamic memory for systems that require an 8M × 16 DRAM organization.
• Industrial equipment — Extended operating temperature (−40 °C to 85 °C) supports deployment in industrial-grade electronics.
• Board-level compact systems — 54-TFBGA (8×8) package enables memory integration where PCB space is constrained.

Unique Advantages

• Deterministic timing: 5.4 ns access time and a 143 MHz clock specification enable predictable memory performance for timing-sensitive designs.
• Standard LVTTL interface: Simplifies integration with common logic voltage domains and controller architectures that use LVTTL signaling.
• Flexible supply range: 3.0 V to 3.6 V operation aligns with standard 3 V system rails for straightforward power design.
• Compact BGA footprint: 54-TFBGA (8×8) reduces PCB area compared with larger packages while supporting surface-mount assembly.
• Extended temperature rating: −40 °C to 85 °C operation supports deployments in environments with wide thermal variation.
• Manufacturer support: Produced by Integrated Silicon Solution Inc (ISSI), providing traceable sourcing and device consistency.
