NDS66PBA-20IT

Memory IC Overview

The NDS66PBA-20IT is a 64 Mbit SDRAM memory integrated circuit manufactured by Insignis Technology Corporation. It features an LVTTL interface and operates at a clock frequency of 200 MHz with a 4.5 ns access time. The device is organized as 4M x 16 bits and functions within a supply voltage range of 3V to 3.6V. It is housed in a 54-FBGA (8x8) surface-mount package and supports an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed data transfer via a 200 MHz clock frequency.
• Utilizes Low Voltage TTL (LVTTL) logic levels for interface compatibility.
• Designed for industrial environments with extended temperature operation capabilities.

Memory IC Applications

• Embedded systems requiring volatile memory storage
• Industrial control equipment
• Consumer electronics devices

Memory IC Procurement Notes

Verify the specific suffix IT against official manufacturer documentation to confirm the industrial temperature grade (-40°C to +85°C). Ensure the 54-FBGA footprint matches the target PCB layout. Confirm RoHS3 compliance status through current datasheets, as regulatory statuses may change over time.

Memory IC Selection Notes

Select this component when a 64 Mbit capacity with LVTTL signaling is required. Compare the 200 MHz speed grade against system timing requirements. Evaluate the 54-FBGA package constraints against available board space and thermal dissipation needs relative to other NDS66 series options.

Memory IC Part Context

This part belongs to the NDS66P series of synchronous DRAMs from Insignis Technology Corporation. It serves as a volatile memory solution for applications needing moderate density and standard parallel interfaces. The FBGA packaging facilitates compact design integration compared to larger leaded packages.

Memory IC Replacement Considerations

Consult official substitution guides for pin-compatible or functionally equivalent parts within the same family. Verify that any alternative maintains the LVTTL interface and 3V-3.6V supply requirements.
