IS42S32200E-7TL-TR

The IS42S32200E-7TL-TR is a 64 Mbit synchronous DRAM (SDRAM) device from ISSI, organized as 2M × 32 with four internal banks for improved throughput. Designed for 3.3 V memory systems and a parallel LVTTL interface, this part targets applications that require synchronous, high-speed volatile storage with programmable burst and latency options within a commercial 0°C to +70°C operating temperature range.

Key Features

• Memory Architecture 64 Mbit organized as 524,288 × 32 × 4 banks (each bank 16,777,216 bits), internally arranged as 2,048 rows × 256 columns × 32 bits for efficient row/column access.
• Synchronous SDRAM Core Fully synchronous operation with all signals referenced to the rising clock edge and pipeline architecture for high-speed data transfer.
• Performance Options Available speed grades include clock frequencies up to 200/166/143/133 MHz; the -7 grade operates at 143 MHz with a typical access time from clock of 5.5 ns (CAS latency = 3).
• Programmability Programmable burst length (1, 2, 4, 8, full page) and burst sequence (sequential/interleave), plus programmable CAS latency (2 or 3 clocks) to match system timing requirements.
• Refresh and Self-Refresh Supports AUTO REFRESH and self-refresh modes. Refresh requirement: 4096 refresh cycles per 16 ms (A2 grade) or per 64 ms for commercial/industrial/A1 grades (commercial grade applies to this device).
• Interface and Logic LVTTL-compatible I/O with parallel memory interface enabling random column access every clock cycle and burst read/write operations with burst termination commands.
• Power Single-supply operation specified at 3.0 V to 3.6 V (standard 3.3 V systems).
• Package & Thermal 86-pin TSOP-II (86-TFSOP) package with 10.16 mm width; commercial operating ambient temperature 0°C to +70°C (TA).

Typical Applications

• High-speed buffer memory systems Suitable for designs that require synchronous, low-latency volatile storage and burst data transfers using a parallel interface.
• Embedded systems with 3.3 V supplies Fits systems operating from 3.0 V to 3.6 V that need configurable burst length and CAS latency to match timing constraints.
• Systems requiring predictable refresh behavior Commercial-grade refresh timing (4096 cycles every 64 ms) and self-refresh modes simplify system memory management.

Unique Advantages

• Configurable performance: Multiple speed grades and selectable CAS latency let designers tune latency and throughput to match system timing requirements.
• Burst-capable transfers: Programmable burst lengths and sequences enable efficient block data movement and reduce controller overhead in burst-heavy workloads.
• Synchronous pipeline architecture: All signals referenced to the clock rising edge and internal bank architecture enable predictable timing and improved effective throughput.
• Standard 3.3 V operation: Single-supply 3.0 V–3.6 V range supports common 3.3 V memory system rails for easy integration.
• Commercial thermal rating: Specified for 0°C to +70°C operation for designs targeting commercial-temperature deployments.
• Compact TSOP-II package: 86-pin TSOP-II footprint provides a space-efficient option for board-level memory implementations.
