AS4C4M16S-6TINTR

Memory IC Overview

The AS4C4M16S-6TINTR is a 64Mb Synchronous DRAM (SDRAM) organized as 4M x 16 bits. It features a 54-pin TSOP II package and operates on a single +3.3V power supply with an LVTTL interface. The device supports a maximum clock frequency of 166 MHz, providing a minimum access time from the clock of 5.4 ns. It includes internal pipelined architecture, programmable mode registers for CAS latency and burst length, and supports Auto Refresh and Self Refresh modes.

Memory IC Feature Summary

• Fully synchronous operation with internal pipelined architecture
• Programmable Mode Registers for CAS Latency, Burst Length, and Burst Type
• Supports Auto Refresh and Self Refresh modes for data retention
• Single +3.3V power supply with LVTTL interface

Memory IC Applications

• High-performance PC applications requiring high memory bandwidth
• Consumer electronics systems utilizing SDRAM interfaces
• Industrial embedded systems operating within specified temperature ranges

Memory IC Procurement Notes

Verify that the specific suffix 'IN' corresponds to the Industrial temperature range (-40°C to +85°C) and Pb/Halogen-free status as defined in the manufacturer's ordering information. Confirm the package type is the 54-pin 400 mil plastic TSOP II. Ensure compatibility with system voltage requirements of +3.3V ± 0.3V before integration.

Memory IC Selection Notes

Select this component when a 64Mb density with a 16-bit data bus width is required. The 166 MHz speed grade is suitable for systems needing fast access times. Consider the 54-pin TSOP II package constraints for PCB layout. Verify that the application can support the necessary refresh cycles (4096 cycles/64ms) and power management modes like Clock Suspend or Power Down.

Memory IC Part Context

This part belongs to the Alliance Memory AS4C4M16S series of Synchronous DRAMs. It shares architectural similarities with other members of the family but differs in speed grades and temperature ratings. The -6 variant specifically denotes the 166 MHz performance level, distinguishing it from slower variants like the -7.

Memory IC Replacement Considerations

Compatible alternatives include the AS4C4M16SA-6TIN and AS4C4M16S-6TCN. Verify pinout compatibility and electrical specifications against the target system design before substitution.
