NDS76PBA-20IT TR

Memory IC Overview

The NDS76PBA-20IT TR is a Synchronous Dynamic Random Access Memory (SDRAM) integrated circuit manufactured by Insignis Technology Corporation. It provides a storage capacity of 128 Megabits, organized as 8 Megawords by 16 bits. The device operates with an LVTTL interface and supports clock frequencies up to 200 MHz. Key timing specifications include a write cycle time of 10 nanoseconds and an access time of 4.5 nanoseconds. It functions within a supply voltage range of 3V to 3.6V and is housed in a 54-pin Thin-Shrink Small Outline Package (TSOP II).

Memory IC Feature Summary

• Supports high-speed data transfer rates via a 200 MHz clock frequency.
• Utilizes Low Voltage Transistor-Transistor Logic (LVTTL) for standard digital interfacing.
• Features fast memory access times of 4.5 ns for efficient read operations.
• Designed for surface-mount installation in compact electronic assemblies.

Memory IC Applications

• Portable consumer electronics requiring volatile data storage.
• Embedded systems utilizing LVTTL-compatible processors.
• Industrial control units operating within specified temperature ranges.
• Communication equipment needing moderate bandwidth memory solutions.

Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing components. Confirm that the 54-TSOP II package dimensions match the target PCB footprint requirements. Ensure the selected variant meets the required -40°C to 85°C ambient temperature operating range for the intended application environment. Cross-reference the manufacturer part number against current distributor listings to confirm availability status.

Memory IC Selection Notes

Select this component when a 128Mb density is required alongside a TSOP II form factor. Compare the 4.5 ns access time against system bus speed requirements to ensure compatibility. Evaluate the 3V to 3.6V power supply constraints against the design's voltage regulation capabilities. Consider the LVTTL interface level if replacing older logic families without level shifters.

Memory IC Part Context

This part belongs to the NDS76P series of SDRAM devices from Insignis Technology Corporation. The series offers various densities and package options, including FBGA and TSOP configurations. The NDS76PBA-20IT TR specifically targets applications requiring a balance between performance and physical size constraints typical of mid-range embedded memory designs.

Memory IC Replacement Considerations

NDS76PT5-20IT TR is listed as a parameter-equivalent alternative offering identical electrical specifications in a TSOP II package. Verify pin-to-pin compatibility before substitution. Other series members like NDS76PBA-20IT exist but utilize different FBGA packaging, requiring layout modifications.
