IS42S16320D-7BLI

The IS42S16320D-7BLI is a 512 Mbit synchronous DRAM (SDRAM) organized as 32M × 16 and provided in a 54-ball TF-BGA package. It implements a pipeline architecture for high-speed synchronous data transfers with all signals referenced to the rising edge of the clock.

Designed as parallel volatile memory for board-level integration, this device targets applications that require a compact, industrial-temperature-capable SDRAM with programmable burst and latency options and a LVTTL-compatible interface.

Key Features

• Memory Core: 512 Mbit SDRAM organized as 32M × 16 with internal bank architecture for hiding row access and precharge operations.
• Performance: Clock frequency up to 143 MHz (–7 grade) with access time of 5.4 ns and programmable CAS latency (2 or 3 clocks) to match system timing.
• Burst and Sequencing: Programmable burst length (1, 2, 4, 8, full page) and selectable burst sequence (sequential/interleave) for flexible data transfer modes.
• Refresh and Reliability: Auto Refresh and Self Refresh supported; 8K refresh cycles every 64 ms as specified for reliable data retention in volatile operation.
• Interface and Signaling: Parallel memory interface with LVTTL-compatible signals and support for burst read/write and burst read/single write operations.
• Power: Power supply range listed as 3.0 V to 3.6 V.
• Package and Mounting: Available in a 54-TF-BGA (54‑TW‑BGA, 8 × 13) ball-grid package for compact board-level mounting.
• Operating Temperature: Rated for –40 °C to +85 °C (TA), suitable for industrial temperature environments.

Typical Applications

• System Memory: Used as parallel SDRAM for designs requiring a 512 Mbit synchronous memory with programmable burst and latency options.
• Industrial Equipment: Suitable for systems operating across –40 °C to +85 °C that need reliable volatile memory in a compact package.
• Board-Level Memory Expansion: Compact 54-ball TF-BGA package supports dense PCB implementations where board space is constrained.
• High-Speed Interfaces: Employed where clocked SDRAM with up to 143 MHz operation and LVTTL signaling is required for synchronous data buffering.

Unique Advantages

• 512 Mbit Density in a Compact Package: Provides 32M × 16 organization in a 54-ball TF-BGA for high-density board-level memory.
• Programmable Performance: CAS latency and burst length options allow tuning memory timing and throughput to match system requirements.
• Pipeline Architecture: Fully synchronous pipeline design references all signals to the rising clock edge, enabling deterministic timing and high-speed transfers.
• Industrial Temperature Range: Operates from –40 °C to +85 °C to meet demanding environmental requirements.
• Refresh and Low-Power Modes: Supports Auto Refresh and Self Refresh with 8K refresh cycles per 64 ms for reliable volatile operation.
• Standard Voltage Range: 3.0 V to 3.6 V power supply compatibility for common system power rails.
