MR4A08BYS35

Memory IC Overview

The MR4A08BYS35 is a 16 Mbit Magnetoresistive Random Access Memory (MRAM) device manufactured by Everspin Technologies. It is organized as 2 M x 8 with an 8-bit data bus width and features parallel interface timing of 35 ns. The component operates within a supply voltage range of 3 V to 3.6 V, drawing 60 mA during active operation and 152 mA at peak. It is housed in a TSOP-II-44 package and supports surface mount installation. The device functions reliably across a temperature range of 0°C to +70°C.

Memory IC Feature Summary

• Provides SRAM-compatible read/write timing for seamless integration into existing designs.
• Ensures data retention for over 20 years without requiring power.
• Offers unlimited read and write endurance capabilities.

Memory IC Applications

• Industrial control systems requiring persistent memory
• Automotive electronics applications
• Consumer devices needing non-volatile storage

Memory IC Procurement Notes

Verify the specific suffix YS35 confirms the TSOP-II-44 package and commercial temperature grade. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for any alternative trace code formats or packaging variations that may affect handling.

Memory IC Selection Notes

Select this part when SRAM-like speed is required alongside non-volatility. Ensure the 35 ns access time meets system latency needs. Verify that the 3.3 V nominal supply voltage aligns with your power architecture. Consider the TSOP-II-44 footprint constraints against available PCB space.

Memory IC Part Context

This component belongs to the MR4A08B series of parallel MRAM devices from Everspin Technologies. It shares core specifications with variants like MR4A08BCYS35 but differs in package type and potentially temperature rating. The series is designed to replace traditional SRAM or Flash in applications demanding high endurance and instant data availability.

Memory IC Replacement Considerations

Direct substitutes include MR4A08BCYS35 if TSOP-II-44 compatibility is maintained. Other family members like MR4A08BMA35 offer BGA packaging instead. Verify pinout compatibility before swapping packages.
