MR4A16BCYS35

Memory IC Overview

The MR4A16BCYS35 is a magnetoresistive random access memory (MRAM) device manufactured by Everspin Technologies. It offers a storage capacity of 16 Mbit, organized as 1M x 16 words with a 16-bit data bus width. The component utilizes a parallel interface and features a typical access time of 35 ns. It operates within a supply voltage range of 3 V to 3.6 V. The device is housed in a TSOP-II-54 surface-mount package and supports an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Provides SRAM-compatible read/write timing characteristics for seamless integration into existing designs.
• Features non-volatile memory technology that retains data without power while offering unlimited write endurance.

Memory IC Applications

• Industrial control systems requiring high endurance and fast access times
• Embedded applications needing non-volatile storage with SRAM-like performance
• Data logging systems demanding reliable write cycles

Memory IC Procurement Notes

Verify the specific suffix code to confirm the package type and temperature grade match the design requirements. Confirm RoHS compliance status through official documentation before procurement. Ensure handling procedures account for moisture sensitivity levels specified in the datasheet to prevent damage during assembly.

Memory IC Selection Notes

Select this part when a 16 Mbit capacity with a 16-bit data bus is required. Choose this model over narrower bus variants if system architecture demands wider data paths. Consider the TSOP-II-54 package constraints regarding board space and thermal management capabilities relative to alternative packages like BGA.

Memory IC Part Context

This component belongs to the MR4A16B series of parallel MRAM devices from Everspin Technologies. The series provides non-volatile memory solutions combining the speed of SRAM with the persistence of flash. Variants within the series differ primarily in package options and operating temperature ranges while maintaining consistent electrical performance specifications.

Memory IC Replacement Considerations

Direct substitutes include other MR4A16B series parts with different packages such as MR4A16BMA35 or MR4A16BUYS45. Verify pin compatibility and electrical parameters before substitution. Cross-reference with MR4A08B series only if 8-bit bus width is acceptable.
