Overview of IS42S86400D-6TL-TR – IC DRAM 512Mbit PAR 54TSOP II
The IS42S86400D-6TL-TR is a 512 Mbit synchronous DRAM (SDRAM) device from Integrated Silicon Solution Inc. It is organized as 64M × 8 with a parallel memory interface and is supplied in a 54-pin TSOP-II package.
Designed for high-speed, fully synchronous operation, this device supports programmable burst lengths and CAS latencies, internal bank architecture for hidden row access/precharge, and standard refresh modes to maintain data integrity in volatile memory applications.
Key Features
- Core / Architecture Fully synchronous SDRAM with internal bank structure that hides row access and precharge for continuous data flow.
- Memory Organization 512 Mbit capacity organized as 64M × 8 across four internal banks.
- Performance Rated for 166 MHz operation (–6 speed grade) with an access time from clock as low as 5.4 ns (CAS latency = 3).
- Programmable Burst and Latency Programmable burst lengths (1, 2, 4, 8, full page) and programmable burst sequence (sequential/interleave); CAS latency programmable to 2 or 3 clocks.
- Refresh and Power Management Supports Auto Refresh and Self Refresh modes with 8K refresh cycles per 64 ms to preserve stored data in volatile operation.
- Interface LVTTL-compatible signaling with a parallel memory interface and support for random column address every clock cycle.
- Power Supply voltage specified from 3.0 V to 3.6 V for the device variant listed.
- Package and Temperature Available in a 54-pin TSOP-II (0.400", 10.16 mm width) package; commercial operating temperature range 0°C to +70°C (TA).
Unique Advantages
- Synchronous pipeline architecture: Enables high-speed data transfer with all I/O referenced to the rising clock edge for predictable timing.
- Flexible data handling: Programmable burst lengths and sequence options let designers match memory behavior to system access patterns.
- Configurable latency: CAS latency selectable between 2 and 3 clocks to balance throughput and timing constraints.
- Robust refresh support: Auto Refresh and Self Refresh with 8K cycles per 64 ms help maintain data integrity in volatile applications.
- Compact package: 54-pin TSOP-II footprint offers a small form factor for board-level integration while providing a parallel x8 memory interface.
Why Choose IC DRAM 512MBIT PAR 54TSOP II?
The IS42S86400D-6TL-TR delivers a practical balance of density, speed and package size for systems requiring 512 Mbit of volatile SDRAM in a 54-pin TSOP-II. Its synchronous pipeline design, programmable burst/latency options and built-in refresh modes make it suitable for designs that need predictable, high-rate parallel memory access within the specified commercial temperature and voltage ranges.
This device is well suited to engineers specifying a compact, parallel SDRAM solution that requires configurable performance characteristics and standard LVTTL interfacing, backed by ISSI’s documented device specifications.
