NDS66PT5-20IT TR

Memory IC Overview

The NDS66PT5-20IT TR is a Synchronous Dynamic Random Access Memory (SDRAM) integrated circuit manufactured by Insignis Technology Corporation. It provides a total storage capacity of 64 Mbit, organized as 4 Megawords by 16 bits. The device operates with an LVTTL interface and supports a clock frequency of 200 MHz, achieving a typical access time of 4.5 ns. It is housed in a 54-pin Thin-Shrink Small Outline Package (TSOP II). The component functions within a supply voltage range of 3.0V to 3.6V and is rated for an industrial operating temperature range from -40°C to +85°C.

Memory IC Procurement Notes

Verify the specific package variant against the datasheet, as similar part numbers may exist in different packages such as FBGA. Confirm that the 'TR' suffix denotes tape and reel packaging if required for automated assembly. Ensure the supplier provides RoHS compliance documentation consistent with the manufacturer's current specifications. Check for any recent product change notices regarding pinout or electrical characteristics.

Memory IC Selection Notes

Select this component when a 64 Mbit SDRAM solution with a TSOP II footprint is required. Compare performance metrics against other members of the NDS66 series, noting that faster variants like the NDS66PBA-20IT utilize FBGA packages. Ensure the design accommodates the 3.3V power supply requirements and the thermal constraints of the TSOP II package within the target application environment.

Memory IC Part Context

This part belongs to the NDS66 series of SDRAM devices from Insignis Technology Corporation. The series includes various densities and speeds, typically ranging from 32 Mbit to 64 Mbit. The NDS66PT5-20IT TR specifically represents the 64 Mbit configuration in a TSOP II package, distinguishing it from higher-speed or differently packaged alternatives like the NDS66PBA-20IT which uses an FBGA form factor.

Memory IC Replacement Considerations

Direct substitutes within the same family include the NDS66PT5-20ET TR, which shares identical electrical specifications but may differ in temperature grade or testing standards. Cross-package replacements such as the NDS66PBA-20IT require careful PCB layout adjustments due to the difference between TSOP II and FBGA footprints.
