Memory IC datasheet and documents for IS45S32800D-7TLA1

IS45S32800D-7TLA1

Memory IC Overview

The IS45S32800D-7TLA1 is a 256Mb Synchronous DRAM manufactured by ISSI. It features an 8M x 32 organization across four internal banks and operates with a single 3.3V power supply. The device supports a maximum clock frequency of 143 MHz and provides an access time of 5.4 ns at CAS latency 3. It utilizes an L VTTL interface and is housed in an 86-pin TSOP-II package.

Memory IC Feature Summary

Supports fully synchronous operation with all signals referenced to the positive clock edge
Includes internal bank architecture for hiding row access and precharge times
Features programmable burst lengths, sequences, and CAS latency settings

Memory IC Applications

High-speed data transfer systems requiring pipeline architecture
Memory subsystems utilizing 3.3V Vdd and Vddq supplies
Applications requiring auto-refresh or self-refresh power-saving modes

Memory IC Procurement Notes

Verify that the specific suffix '7' corresponds to the 143 MHz speed grade and 5.4 ns access time as defined in the datasheet timing tables. Confirm the package type matches the 86-pin TSOP-II specification. Ensure the operating temperature range requirements align with the Industrial or Automotive A1 grades available for this series.

Memory IC Selection Notes

Select this component when a 256Mb density with a 32-bit data bus width is required. It is suitable for designs needing a 3.3V single-supply operation with L VTTL compatibility. Consider the 86-pin TSOP-II form factor if board space constraints favor this surface-mount package over BGA options.
