NDS66PBA-16IT

Memory IC Overview

The NDS66PBA-16IT is a Synchronous Dynamic Random Access Memory (SDRAM) integrated circuit manufactured by Insignis Technology Corporation. It provides a storage capacity of 64 Mbit, organized as 4M words 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 Thin Fine-pitch Ball Grid Array (54-FBGA) package measuring 8x8 mm. The component functions within a supply voltage range of 3V to 3.6V and is rated for an operating temperature between -40°C and 85°C.

Memory IC Feature Summary

• Supports fully synchronous operation with all signals referenced to the positive clock edge
• Includes internal bank architecture to hide row access and precharge times
• Capable of auto-refresh and self-refresh modes for data retention

Memory IC Applications

• Embedded systems requiring volatile memory storage
• Consumer electronics utilizing LVTTL interfaces
• Industrial control units operating in extended temperature ranges

Memory IC Procurement Notes

Verify the specific suffix 'BA' against official manufacturer documentation to confirm pinout and electrical characteristics, as variations exist within the NDS66 series. Ensure compatibility with LVTTL logic levels and 3V to 3.6V power supplies. Confirm the 54-FBGA footprint matches the target PCB design. Check current availability status due to potential supply constraints.

Memory IC Selection Notes

Select this component when a 64 Mbit density is required in a compact FBGA form factor. It is suitable for designs needing 16-bit data width at 166 MHz speeds. Consider the -40°C to 85°C industrial temperature rating for harsh environments. Verify that the system power budget aligns with the specified 3V to 3.6V operating range.

Memory IC Part Context

This part belongs to the NDS66P family of SDRAM devices from Insignis Technology Corporation. It shares architectural similarities with other members like the NDS36PT5-16IT but differs in density and packaging. The NDS66 series is designed for applications requiring moderate memory capacity with high-speed synchronous access capabilities.
