AS4C64M16D1-6TCNTR

Memory IC Overview

The AS4C64M16D1-6TCNTR is a 1 Gbit (64 M x 16) DDR SDRAM manufactured by Alliance Memory. It operates at a maximum clock frequency of 166 MHz with an access time of 700 ps. The device requires a supply voltage between 2.3 V and 2.7 V, with a maximum power consumption of 230 mA. It is housed in a 66-pin TSOP-II package designed for surface mount technology. The component supports commercial operating temperatures ranging from -40°C to +85°C and includes humidity sensitivity features.

Memory IC Feature Summary

• Supports high-speed data transfer via Double Data Rate architecture
• Utilizes low-voltage operation for reduced power consumption
• Designed for surface-mount integration on printed circuit boards

Memory IC Applications

• Consumer electronics requiring embedded memory storage
• Industrial control systems needing reliable data retention
• Telecommunications equipment utilizing synchronous dynamic RAM

Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging rather than tray distribution. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure the ordering quantity aligns with the supplier's standard pack sizes. Validate that the 166 MHz speed grade meets system timing requirements. Check for moisture sensitivity level ratings if reflow soldering is planned.

Memory IC Selection Notes

Select this component when a 1 Gbit capacity with a 16-bit data bus width is required. The 166 MHz speed grade suits applications needing moderate bandwidth without higher latency penalties. The TSOP-II package offers a cost-effective solution for space-constrained designs compared to BGA options. Ensure the system voltage regulator can maintain stability within the 2.3 V to 2.7 V range during peak current draw.

Memory IC Part Context

This part belongs to the AS4C64M16D1 series of DDR SDRAM devices from Alliance Memory. It shares architectural similarities with other members like the AS4C64M16D1-6TIN but differs in packaging format. The series provides scalable memory solutions for various digital signal processing and general-purpose computing tasks.

Memory IC Replacement Considerations

The AS4C64M16D1-6TCN is a pin-compatible alternative available in tray packaging. Verify electrical specifications match exactly before substitution. Cross-reference timing parameters to ensure compatibility with existing controller logic.
