MR4A16BUYS45R

Memory IC Overview

The MR4A16BUYS45R is a 16 Mbit magnetoresistive random access memory (MRAM) device manufactured by Everspin Technologies. It features a parallel interface with a data bus width of 16 bits and an organization of 1M x 16. The component operates within a supply voltage range of 3 V to 3.6 V, with a maximum access time of 45 ns. It is housed in a TSOP-II-54 package and supports surface mount installation. The device functions reliably across an extended temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Provides SRAM-compatible read/write timing characteristics for seamless integration into existing designs.
• Offers unlimited endurance due to the non-volatile magnetic tunnel junction technology.
• Supports high-temperature operation suitable for demanding industrial environments.

Memory IC Applications

• Industrial control systems requiring non-volatile storage
• Automotive electronics operating under harsh thermal conditions
• Data logging applications needing high endurance

Memory IC Procurement Notes

Verify the specific suffix 'S45' against the manufacturer's latest datasheet to confirm pinout compatibility and electrical specifications. Ensure that the procurement channel provides components with valid RoHS compliance documentation. Confirm moisture sensitivity level handling requirements prior to assembly to prevent package damage during soldering processes.

Memory IC Selection Notes

Select this part when a parallel interface is required for direct CPU connection without additional controller overhead. Consider the 45 ns access time relative to system clock speeds. Evaluate the TSOP-II-54 footprint against available PCB space. Compare power consumption figures at 3V versus 3.3V if low-power operation is critical for the application design.

Memory IC Part Context

This component belongs to the MR4A16B series of parallel MRAM devices from Everspin Technologies. The series is designed to replace traditional SRAM or Flash memory in applications where non-volatility and high write endurance are essential. It shares architectural similarities with other members of the MR4 family but differs in capacity and speed grades.

Memory IC Replacement Considerations

Check for MR4A16BUYS35R for faster 35 ns access times. Verify MR4A16BUYS45 for identical specifications in tray packaging instead of reel/cut tape formats.
