IS42S32160B-75ETLI

The IS42S32160B-75ETLI is a 512Mbit synchronous DRAM organized as 16M × 32 with a quad-bank architecture and a parallel LVTTL interface. It uses a pipelined synchronous architecture to support high-speed data transfer and programmable burst operations.

This device is intended for designs that require volatile SDRAM storage with a 3.0–3.6V supply, support for programmable CAS latency and burst sequencing, and industrial temperature operation to −40°C to +85°C.

Key Features

• Memory Architecture  512 Mbit SDRAM organized as 16M × 32 and implemented as 4M × 32 × 4 banks for internal bank interleaving and efficient row handling.
• Synchronous Pipeline Operation  Fully synchronous operation with all signals referenced to the rising edge of CLK to enable predictable timing and pipeline data transfer.
• Clock and Timing  Clock frequency rating of 133 MHz and access time down to 5.5 ns (device timing options include programmable CAS latency 2 or 3 as specified in the datasheet).
• Burst Control  Programmable burst length (1, 2, 4, 8, full page) and selectable burst sequence (sequential or interleave) for flexible throughput patterns.
• Refresh and Power Modes  Supports Auto Refresh (CBR) and Self Refresh; refresh options per datasheet include 8192 refresh cycles with selectable refresh timing options.
• Interface  LVTTL-compatible signals and a parallel memory interface for direct integration into synchronous memory subsystems.
• Supply Voltage  Operates from 3.0 V to 3.6 V (3.3 V ±0.3 V), compatible with standard 3.3 V memory systems.
• Package  86-pin TSOP II package (86-TFSOP, 0.400" / 10.16 mm width) optimized for surface-mount applications.
• Operating Temperature  Industrial-range operation from −40°C to +85°C for use in temperature-demanding environments.

Typical Applications

• Embedded memory subsystems  Used where high-speed, synchronous DRAM storage with programmable burst and CAS timing is required.
• Industrial control systems  Suitable for systems that require operation across −40°C to +85°C and reliable refresh/self-refresh capabilities.
• Network and communications equipment  Fits designs needing parallel SDRAM with low access times and bank interleaving to sustain data throughput.
• High-performance buffering  Employed as a high-speed buffer or working memory where 512 Mbit capacity and 133 MHz clock operation are needed.

Unique Advantages

• Synchronous pipeline architecture: Enables consistent, clock-referenced data flow and predictable timing for system design.
• Flexible burst and CAS control: Programmable burst length and sequence plus selectable CAS latency allow tuning for throughput or latency needs.
• Quad-bank organization: Four internal banks provide the ability to hide row precharge time and support interleaved accesses for higher effective bandwidth.
• Industrial temperature range: −40°C to +85°C operation supports deployment in temperature-challenging environments.
• Standard 3.3 V supply range: 3.0–3.6 V operation ensures compatibility with common 3.3 V memory systems.
• Industry-standard TSOP II package: 86-pin TSOP-II package provides a compact surface-mount footprint for board-level integration.
