Overview of IS42S16320D-7TLI – IC DRAM 512MBIT PAR 54TSOP II
The IS42S16320D-7TLI is a 512Mbit synchronous DRAM (SDRAM) organized as 32M × 16 with a parallel memory interface in a 54-pin TSOP-II package. It implements a fully synchronous pipeline architecture with internal bank management to optimize high-speed data transfers.
Designed for systems that require deterministic SDRAM timing and industrial operating range, this device offers a 143 MHz clock option, programmable CAS latency and burst features to match a variety of memory access patterns while operating from a 3.0 V–3.6 V supply.
Key Features
- Memory Organization: 32M × 16 configuration providing 512 Mbit of volatile SDRAM in a single package.
- Performance: 143 MHz clock frequency (–7 speed grade) with typical access time of 5.4 ns for fast read access.
- Programmable Timing and Burst: Programmable CAS latency (2 or 3 clocks) and selectable burst lengths (1, 2, 4, 8, full page) with sequential or interleaved burst sequence options.
- Synchronous Architecture & Bank Management: Fully synchronous operation referenced to the rising clock edge and internal bank architecture for hiding row access/precharge latency.
- Refresh and Power Modes: Supports Auto Refresh and Self Refresh with 8K refresh cycles every 64 ms to maintain data integrity.
- Interface and Signaling: Parallel memory interface with LVTTL-compatible signaling.
- Power Supply: Operates from 3.0 V to 3.6 V supply.
- Package and Mounting: 54-pin TSOP-II (0.400", 10.16 mm width) package for surface-mount designs.
- Operating Temperature: Industrial temperature range of −40°C to +85°C (TA).
Unique Advantages
- Deterministic synchronous operation: Fully synchronous, clock-referenced design simplifies timing integration with host controllers.
- Flexible access patterns: Programmable burst lengths and burst sequence options allow tuning for both sequential and random access workloads.
- Latency control: Selectable CAS latency (2 or 3) enables trade-offs between speed and system timing margins.
- Robust refresh features: Auto and self-refresh modes with 8K/64 ms support reduce host refresh management and help preserve data across suspend states.
- Industrial-ready thermal range: Rated for −40°C to +85°C operation to support temperature-demanding deployments.
- Compact surface-mount package: 54-pin TSOP-II footprint provides a space-efficient memory solution for board-level integration.
Why Choose IC DRAM 512MBIT PAR 54TSOP II?
