IS42S32400F-6TLI

Memory IC Overview

The IS42S32400F-6TLI is a 128Mb Synchronous DRAM manufactured by ISSI. It features a 4M x 32 organization and operates at a maximum clock frequency of 166 MHz with a 6.5 ns access time. The device utilizes an LVTTL interface and requires a single 3.3V power supply (3.0V to 3.6V). It is housed in an 86-pin TSOP-II package and supports industrial operating temperatures ranging from -40°C to +85°C.

Memory IC Feature Summary

• Supports internal bank interleaving to hide row access and precharge times for seamless high-speed random-access operations.
• Features programmable burst lengths including 1, 2, 4, 8, or full page configurations with sequential or interleave sequences.
• Includes auto-refresh and self-refresh modes to maintain data integrity while optimizing power consumption.

Memory IC Applications

• Wireless access points and base stations
• Network routers and storage systems
• Industrial control systems
• Automotive telematics and infotainment

Memory IC Procurement Notes

Verify the specific suffix '6TLI' against the manufacturer's datasheet to confirm the exact speed grade (-6), package type (TSOP-II), and temperature range (Industrial). Ensure compatibility with system voltage requirements and check for moisture sensitivity handling procedures during assembly.

Memory IC Selection Notes

Select this component when a 32-bit wide memory interface is required for high-speed synchronous data transfer. Consider the 86-pin TSOP-II form factor for surface-mount applications where space constraints align with its dimensions. Verify that the target application supports LVTTL logic levels and standard SDRAM timing protocols.

Memory IC Part Context

This part belongs to the IS42S32400 series of 128Mb SDRAMs from ISSI. The series offers various speed grades and packaging options, including BGA variants. The 'IS42' prefix denotes commercial/industrial grade devices, distinct from automotive-grade parts which typically carry the 'IS45' designation.

Memory IC Replacement Considerations

Compatible substitutes include the IS42S32400J-6TLI-TR and IS42S32400F-7TLI. Verify pinout compatibility and ensure the replacement meets the required 166 MHz clock frequency and -40°C to +85°C temperature specifications.

Memory IC FAQ

How does the Auto Precharge function operate?

Auto Precharge initiates the precharge process automatically at the end of a read or write burst sequence if enabled via the A10 pin, eliminating the need for a separate precharge command.

What is the refresh requirement for this device?

The device requires 4096 refresh cycles every 64ms for Commercial and Industrial grades, ensuring data retention within the memory array.
