Technical Overview

The IS42S32400F-6TLI-TR is a 128-megabit synchronous DRAM manufactured by ISSI, organized as 4 million words by 32 bits. This high-performance memory component operates at 3.3V with a maximum clock frequency of 166 MHz, packaged in an 86-pin TSOP II (400 mil) configuration that complies with RoHS environmental standards. The device utilizes advanced pipeline architecture to achieve high-speed data transfers while maintaining synchronization with the system clock.

Key Features

High-speed operation supporting clock frequencies of 166 MHz, 143 MHz, and 133 MHz
Programmable CAS latency of 2 or 3 clock cycles for timing optimization
Flexible burst operations with programmable burst lengths of 1, 2, 4, 8, or full page
Multiple refresh modes including Auto Refresh (CBR) and Self Refresh capabilities
Internal bank architecture with four banks for efficient row access and precharge operations
LVTTL-compatible interface ensuring broad system compatibility
Temperature range options supporting commercial, industrial, and automotive applications

Technical Specifications

This SDRAM operates from a single 3.3V power supply with ±0.3V tolerance and features a fully synchronous design where all signals reference to positive clock edges. The memory organization consists of 1M x 32-bit x 4 banks, providing efficient memory management and access patterns. The device supports both sequential and interleave burst sequences, with burst termination controlled through burst stop and precharge commands. Refresh operations maintain 4096 cycles every 16ms for A2 grade or 64ms for commercial, industrial, and A1 grade variants.

Industry Applications

This memory component is engineered for demanding applications across multiple sectors. In networking equipment, it provides the high-speed data buffering required for packet processing and switching systems. Industrial automation systems benefit from its reliable operation across extended temperature ranges, while automotive electronics utilize its robust performance in vehicle control and infotainment systems. The device also serves computing applications requiring efficient memory subsystems, including embedded systems, workstations, and communication infrastructure where consistent data throughput and timing precision are critical.
