IS42S16320D-7TLI-TR

The IS42S16320D-7TLI-TR is a 512 Mbit synchronous DRAM device organized as 32M × 16. It uses a pipelined, fully synchronous architecture with parallel memory interface and LVTTL signaling for high-speed, clock-referenced operation.

Designed for board-level memory expansion where a 54-pin TSOP-II package and industrial temperature range are required, this device delivers programmable burst modes, selectable CAS latency, and standard SDRAM refresh modes to support system memory requirements.

Key Features

• Memory Core  The device is a 512 Mbit SDRAM organized as 32M × 16 with internal bank architecture to hide row access/precharge latency.
• Performance  Clock frequency up to 143 MHz (‑7 speed grade) with access time of 5.4 ns and programmable CAS latency (2 or 3 clocks).
• Interface  Parallel memory interface with LVTTL signaling for standard synchronous DRAM connectivity.
• Burst and Mode Control  Programmable burst lengths (1, 2, 4, 8, full page) and burst sequences (sequential/interleave); supports burst read/write and burst read/single write operations with burst termination commands.
• Refresh and Self-Refresh  Supports Auto Refresh and Self Refresh with 8K refresh cycles per 64 ms (standard SDRAM refresh behavior).
• Power  Supply voltage range specified at 3.0 V to 3.6 V for this device variant.
• Package & Temperature  54-pin TSOP-II (0.400", 10.16 mm width) package; operating temperature range −40 °C to +85 °C (TA).

Typical Applications

• Embedded and Industrial Systems  Board-level memory expansion where a 512 Mbit parallel SDRAM in a 54-pin TSOP-II package is required and operation to −40 °C is needed.
• Legacy Parallel SDRAM Designs  Replacement or population of existing designs that use parallel SDRAM interfaces and LVTTL signaling.
• Networking and Communications Modules  Local buffering and working memory in modules that require synchronous DRAM with programmable burst and CAS latency.
• Repair and Prototyping  Use in prototype boards or repair applications that specify the 54-TSOP II package and 32M × 16 organization.

Unique Advantages

• Synchronous, pipelined architecture: Enables clock-referenced operation and predictable timing for systems designed around a positive clock edge.
• Flexible performance tuning: Programmable CAS latency and burst configurations let designers trade latency and throughput to match system timing.
• Industrial temperature support: Specified operation from −40 °C to +85 °C for use in temperature-sensitive environments.
• Compact TSOP-II footprint: 54-pin TSOP-II package (10.16 mm width) simplifies PCB routing for board-level memory implementations.
• Standard refresh behavior: Auto and self-refresh support with 8K refresh cycles per 64 ms for reliable dynamic memory retention management.
