NDS73PT9-20AT

Memory IC Overview

The NDS73PT9-20AT is a Synchronous Dynamic Random Access Memory (SDRAM) integrated circuit manufactured by Insignis Technology Corporation. It provides a storage capacity of 128 Mbit, organized as 4M x 32 bits. The device utilizes an LVTTL memory interface and operates with a clock frequency of 200 MHz. It functions within a supply voltage range of 3V to 3.6V and supports an extended operating temperature range from -40°C to 105°C. The component is housed in an 86-TSOP II package.

Memory IC Feature Summary

• High-speed synchronous data transfer capability via LVTTL interface
• Extended industrial temperature operation for harsh environments
• Compact surface-mount packaging for space-constrained designs

Memory IC Applications

• Industrial control systems requiring reliable volatile memory
• Embedded computing platforms with high-speed data processing needs
• Automotive electronics operating under extreme thermal conditions

Memory IC Procurement Notes

Verify the specific suffix 'AT' against official manufacturer documentation to confirm the extended temperature rating (-40°C to 105°C). Ensure compatibility with LVTTL logic levels in the target system design. Confirm package dimensions match the 86-TSOP II specification before integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Memory IC Selection Notes

Select this component when a 128 Mbit density is required alongside a 32-bit data width. The 200 MHz clock speed suits applications needing rapid data throughput. The wide temperature range makes it suitable for automotive or outdoor industrial use where standard commercial grade parts would fail. Ensure the host controller supports the LVTTL interface protocol.

Memory IC Part Context

This part belongs to the NDS73 series of SDRAM devices from Insignis Technology Corporation. The series focuses on providing high-performance memory solutions using advanced DRAM manufacturing processes. The NDS73PT9-20AT represents a variant optimized for higher clock speeds and broader environmental tolerance compared to standard commercial versions.

Memory IC Replacement Considerations

The NDS73PT9-16IT TR is a similar 128 Mbit SDRAM in the same package but operates at 166 MHz and typically has a lower temperature range. Verify if the reduced clock speed meets system requirements before substitution.
