NDS66PBA-16ET

Memory IC Overview

The NDS66PBA-16ET is a Synchronous Dynamic Random Access Memory (SDRAM) integrated circuit manufactured by Insignis Technology Corporation. It provides a total storage capacity of 64 Megabits, organized as 4 Megawords by 16 bits. The device operates with an LVTTL interface and supports a clock frequency of 166 MHz. It features a 5.4 ns access time and is housed in a 54-pin Fine-Pitch Ball Grid Array (FBGA) package measuring 8x8 mm. The component functions within a supply voltage range of 3V to 3.6V and is rated for operation across a temperature range of -40°C to 85°C.

Memory IC Feature Summary

• Provides 64Mbit volatile memory storage using SDRAM technology
• Supports high-speed data transfer via LVTTL interface at 166 MHz
• Designed for surface-mount installation in compact electronic assemblies

Memory IC Applications

• Embedded systems requiring non-volatile or volatile data buffering
• Consumer electronics utilizing standard DRAM interfaces
• Industrial control units operating within specified temperature ranges

Memory IC Procurement Notes

Verify the specific suffix ET against official datasheets to confirm package type and speed grade compatibility. Ensure that the 54-FBGA footprint matches the target PCB design. Confirm RoHS compliance status and moisture sensitivity level requirements before integration into production workflows.

Memory IC Selection Notes

Select this component when a 64Mbit density is required with a 16-bit data width. The FBGA package offers a smaller form factor compared to TSOP alternatives. Verify that the system power supply can maintain the 3V to 3.6V range under all load conditions to ensure stable operation.

Memory IC Part Context

This part belongs to the NDS66 series of SDRAM devices from Insignis Technology Corporation. The series typically includes variants with different densities and packages. The NDS66PBA-16IT is a similar variant often found in the same product family, sharing core electrical characteristics but potentially differing in packaging or testing specifications.

Memory IC Replacement Considerations

The NDS66PBA-16IT is a documented alternative within the same manufacturer's lineup. Cross-reference pinouts and electrical parameters carefully. Other manufacturers' 64Mbit SDRAMs may require significant schematic and layout modifications due to interface differences.
