AS4C4M16SA-6TCNTR

Memory IC Overview

The AS4C4M16SA-6TCNTR is a 64 Mbit Synchronous Dynamic Random Access Memory (SDRAM) manufactured by Alliance Memory. It features a 16-bit data bus width and an organization of 4 Megawords by 16 bits. The device operates with a maximum clock frequency of 166 MHz and has a typical access time of 5.4 ns. It requires a single 3.3V power supply, operating within a voltage range of 3.0 V to 3.6 V. The component is housed in a 54-pin TSOP-II package and supports commercial temperature ranges from 0°C to +70°C.

Memory IC Feature Summary

• Fully synchronous operation utilizing a standard SDRAM interface for high-speed data transfer.
• Internally configured as four banks to enable concurrent operations and improved bandwidth efficiency.
• Designed for lead-free and halogen-free compliance, supporting environmentally conscious manufacturing processes.

Memory IC Applications

• Communications equipment requiring high memory bandwidth
• Medical devices needing reliable data storage
• Consumer products utilizing SDR technology

Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm that the 'A die' designation matches the required silicon revision for your design. Ensure the 54-pin TSOP-II footprint aligns with your PCB layout constraints. Check RoHS compliance documentation for final assembly requirements.

Memory IC Selection Notes

Select this component when a 64 Mbit capacity with a 16-bit interface is required. The 166 MHz speed class suits applications needing moderate to high throughput. Consider the TSOP-II form factor for space-constrained designs where BGA packages are unsuitable. Verify thermal performance within the commercial temperature range for your specific enclosure.

Memory IC Part Context

This part belongs to the AS4C4M16SA series of CMOS Synchronous DRAMs. It shares architectural similarities with other members like the AS4C8M16S and AS4C16M16S, differing primarily in density and pinout configurations. The SC4 family designation highlights its role in providing scalable memory solutions for various bandwidth demands.

Memory IC Replacement Considerations

Direct substitutes include other parts within the AS4C4M16SA series with compatible timing parameters. Cross-referencing with ISSI or Micron equivalents requires careful verification of pinouts and electrical characteristics due to potential functional differences.
