AS4C16M16D1A-5TCNTR

Memory IC Overview

The AS4C16M16D1A-5TCNTR is a 256 Mbit (16 M x 16) DDR SDRAM component manufactured by Alliance Memory. It operates with a maximum clock frequency of 200 MHz and features a 700 ps access time. The device requires a supply voltage between 2.3 V and 2.7 V. It is housed in a 66-pin TSOP-II package designed for surface mount technology. The unit supports an industrial temperature range from -40°C to +85°C and includes humidity sensitivity classification.

Memory IC Feature Summary

• Supports double data rate synchronous dynamic random access memory architecture
• Provides high-speed data transfer capabilities at up to 200 MHz
• Designed for industrial-grade environmental stability

Memory IC Applications

• Industrial control systems requiring robust memory solutions
• Embedded computing platforms operating in extreme temperatures
• High-performance consumer electronics utilizing DDR interfaces

Memory IC Procurement Notes

Verify the specific suffix 'CNTR' indicates tape and reel packaging configuration rather than tray distribution. Confirm that the industrial temperature grade (-40°C to +85°C) aligns with your system's thermal requirements. Ensure voltage specifications match your power management design constraints before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 256 Mbit capacity with a 16-bit data bus width is required. Choose this part over commercial variants if operation within the extended industrial temperature range is necessary. Consider the TSOP-II form factor for compatibility with existing board layouts and assembly processes.

Memory IC Part Context

This model belongs to the AS4C16M16D1A series, representing a specific density and organization variant within Alliance Memory's DDR SDRAM portfolio. It shares architectural similarities with other members of the family but differs in storage capacity and pinout configuration compared to lower-density options like the 64 Mbit or 128 Mbit versions.

Memory IC Replacement Considerations

Check for direct cross-references such as the AS4C16M16D1A-5TIN, noting differences in packaging type. Verify electrical compatibility with alternative manufacturers offering equivalent 256 Mbit DDR parts.
